II. General information on data processing

1. Scope of processing of personal data

As a matter of principle, we process our users' personal data only insofar as this is necessary to provide a functional website and our content and services. Our users' personal data are processed only on the basis of consent or a legal permission. An exception applies in cases where obtaining prior consent is not possible for factual reasons and the processing of the data is permitted by law.

2. Legal basis for the processing of personal data

Insofar as we obtain the consent of the data subject for processing operations involving personal data, Art. 6(1)(a) of the General Data Protection Regulation (GDPR) serves as the legal basis.

For the processing of personal data necessary for the performance of a contract to which the data subject is a party, Art. 6(1)(b) GDPR serves as the legal basis. This also applies to processing operations necessary to carry out pre-contractual measures. Insofar as processing of personal data is necessary to fulfill a legal obligation to which our company is subject, Art. 6(1)(c) GDPR serves as the legal basis.

If vital interests of the data subject or another natural person require the processing of personal data, Art. 6(1)(d) GDPR serves as the legal basis.

If processing is necessary to safeguard a legitimate interest of our company or a third party and the interests, fundamental rights and freedoms of the data subject do not override the former interest, Art. 6(1)(f) GDPR serves as the legal basis for the processing.

3. Data erasure and storage period

The personal data of the data subject are deleted or blocked as soon as the purpose of storage no longer applies. Data may also be stored beyond this if provided for by European or national legislators in EU regulations, laws or other provisions to which the controller is subject. Data are also blocked or deleted when a storage period prescribed by the aforementioned standards expires, unless further storage of the data is necessary for concluding or performing a contract.

III. Hosting, provision of the website and log files

1. Hosting

Our website is operated by domainfactory GmbH, Oskar-Messter-Str. 33, 85737 Ismaning, Germany. The servers are located in Germany. A data processing agreement pursuant to Art. 28 GDPR is in place with the provider.

2. Description and scope of data processing

Each time our website is accessed, our system automatically collects data and information from the computer system of the accessing computer. The following data are collected:

(1) IP address of the user
(2) Date and time
(3) URL accessed
(4) Referring URL (if any)
(5) Browser identifier

The data are also stored in our system's log files. These data are not stored together with other personal data of the user.

To protect against attacks, we store the IP address for a maximum of 15 minutes after failed login attempts; after five failed attempts, login from this address is temporarily blocked.

3. Legal basis for data processing

The legal basis for the temporary storage of data and log files is Art. 6(1)(f) GDPR.

4. Purpose of data processing

Temporary storage of the IP address by the system is necessary to enable delivery of the website to the user's computer. For this purpose, the user's IP address must remain stored for the duration of the session.

Data are stored in log files to ensure the functionality of the website. We also use the data to optimize the website and to ensure the security of our information technology systems. The data are not evaluated for marketing purposes in this context. These purposes also constitute our legitimate interest in data processing pursuant to Art. 6(1)(f) GDPR.

5. Storage period

The data are deleted as soon as they are no longer required for the purpose for which they were collected. In the case of data collected for providing the website, this is the case when the respective session has ended. In the case of data stored in log files, this is the case after seven days at the latest. Storage beyond this is possible. In this case, the users' IP addresses are deleted or anonymized so that the accessing client can no longer be identified.

6. Options to object and remove

Collecting data for providing the website and storing data in log files is essential for operating the website. An objection under Art. 21 GDPR is possible, but means that the website cannot be used.

IV. Cookies, local storage and consent management

1. Technically necessary cookies and local storage

For logging in to the customer account, we set technically necessary cookies (session, login). Some online tools store settings exclusively in your browser (local storage), for example the selected language of the spec sheet, your own table values, the most recently used piping specs or Catalog Checker settings. This information is not transmitted to us. The legal basis is Section 25(2) No. 2 TDDDG in conjunction with Art. 6(1)(b) or (f) GDPR; storage is necessary to provide the functions you request. You can delete these data in your browser at any time.

2. Analytics cookies

We only set analytics cookies (Google Analytics 4, see Section XIII) with your consent (Section 25(1) TDDDG, Art. 6(1)(a) GDPR). Without consent, they are not set.

3. Consent management with Borlabs Cookie

We obtain your consent via the cookie banner "Borlabs Cookie". The plugin runs on our own server; it stores your selection (consent ID, time, selected services) in a cookie in your browser and as proof on our server. The legal basis is Art. 6(1)(c) GDPR (obligation to provide proof) in conjunction with Art. 7(1) GDPR. You can change or withdraw your selection at any time via the cookie settings. How long your selection remains stored is shown in the cookie settings for the respective entry.

4. Your options

Cookies are stored on the user's computer and transmitted from it to our site. By changing the settings in your web browser, you can disable or restrict the transmission of cookies. Cookies that have already been stored can be deleted at any time. If technically necessary cookies are disabled, it may no longer be possible to use all functions of the website, such as login.

V. Newsletter

1. Description and scope of data processing

On our website you can subscribe to a free newsletter. When you subscribe, the data from the input form are transmitted to us. Subscription uses the double opt-in procedure: you receive an email with a confirmation link; we only send the newsletter after confirmation. The date, time and IP address of subscription and confirmation are also stored as proof. The newsletter is sent via our own website; the data are not passed on to third parties.

2. Legal basis

The legal basis is your consent pursuant to Art. 6(1)(a) GDPR; for proof of consent, Art. 6(1)(c) GDPR.

3. Purpose

The email address is used to deliver the newsletter. The other information serves to prevent misuse of the services or of the email address used and to be able to prove consent.

4. Storage period, withdrawal

The email address is stored as long as the subscription is active. You can unsubscribe from the newsletter at any time; every newsletter contains a link for this. This also withdraws your consent. We retain proof of consent for up to three years after the end of the subscription.

VI. Contact form and email contact

1. Description and scope of data processing

Our website has contact forms that can be used for electronic contact. If a user takes advantage of this option, the data entered in the input form are transmitted to us and stored, in particular name, email address, company and – if provided – telephone and location. At the time the message is sent, the IP address of the user's computer and the date and time are also stored.

Alternatively, you can contact us via the email addresses provided. In this case, the user's personal data transmitted with the email will be stored. Our email mailboxes are operated via Microsoft 365 (Microsoft Ireland Operations Ltd., Dublin), see Section XV.

The data are used exclusively for handling the enquiry.

2. Legal basis for data processing

If the user has given consent, the legal basis for processing the data is Art. 6(1)(a) GDPR. The legal basis for processing data transmitted in the course of sending an email is Art. 6(1)(f) GDPR. If the contact aims at concluding a contract, the additional legal basis for processing is Art. 6(1)(b) GDPR.

3. Purpose of data processing

We process the personal data from the input form solely to handle the contact. In the case of contact by email, this also constitutes the necessary legitimate interest in processing the data. The other personal data processed during the sending process serve to prevent misuse of the contact form and to ensure the security of our information technology systems.

4. Storage period

The data are deleted as soon as they are no longer required for the purpose for which they were collected. For personal data from the input form of the contact form and those sent by email, this is the case when the respective conversation with the user has ended. The conversation has ended when it can be inferred from the circumstances that the matter in question has been conclusively resolved. Statutory retention obligations (e.g. for business letters under Section 257 HGB) remain unaffected. The additional personal data collected during the sending process are deleted after seven days at the latest.

5. Options to object and remove

The user can withdraw consent to the processing of personal data at any time. If the user contacts us by email, they can object to the storage of their personal data at any time. In such a case, the conversation cannot be continued. All personal data stored in the course of the contact will then be deleted, unless there is a statutory retention obligation.

VII. Customer account

1. Description and scope of data processing

You can create a free customer account for our online tools, work aids, downloads and orders. In doing so, we process your salutation, first and last name, company, business email address, telephone and location, your professional background (e.g. user, piping design engineer, university teaching, studies; we confirm this information upon activation), your password (stored only as a hash), the time of your consent to the privacy policy and – if requested – your newsletter subscription. We activate new accounts manually after a review; for this purpose, we compare the email address with our customer records. For this comparison, the website holds only checksums (hashes) of the email addresses of our contacts and their company domains, no names.

In the account, we store which content you have unlocked and downloaded, your information for the training needs assessment and your use of the online tools (see Section X).

2. Legal basis

Art. 6(1)(b) GDPR (user relationship or contract); for the review before activation, Art. 6(1)(f) GDPR – our legitimate interest is protecting our tools and data against misuse.

3. Storage period

We store the data for as long as the account exists. You can request deletion of your account at any time by email to homepage@seitz-ingenieure.de. We retain data on orders and invoices in accordance with the statutory periods (Section 147 AO, Section 257 HGB: up to ten years).

VIII. Orders, activation and downloads

Orders and quote requests via our order form are directed exclusively at businesses. We process the information from the form (company, contact person, billing address, email, telephone, service ordered) for handling, invoicing and activation. We manage access with the WordPress plugin "Paid Member Subscriptions" on our own server; we create the invoice in our ERP system. We remind you by email before access expires.

To protect our content, downloaded files and program files of the online tools contain an identifier of your customer account; every download is logged with date, file and account. This allows us to trace which account a file came from in the event of unauthorized disclosure.

Legal basis: Art. 6(1)(b) GDPR (contract), Art. 6(1)(c) GDPR (retention obligations) and, for the identifier, Art. 6(1)(f) GDPR (protection of our copyrights and database rights). Storage period: order and invoice data up to ten years, access logs until the end of the access term plus 12 months.

IX. Training: booking requests, participant access, evaluation and certificate

1. Booking requests

You can request training dates via the training calendar. We process the information from the form (course, date, location, number of participants, company, contact person, participants, billing address, email, telephone) to handle the request and conduct the training. We obtain dates and prices from a shared schedule of our partner Contelos GmbH; no personal data are transmitted in the process. Requests for courses conducted by Contelos-Seitz Consulting GmbH (currently Revit/BIM, Vault and infrastructure/GIS) are forwarded to it in copy.

2. Participant access

Participants in our training courses receive three months' free access to the corresponding online content. For this purpose, we create a customer account with name and email address; for online training, we take this information from the Microsoft Teams attendance list.

3. Evaluation and certificate of attendance

After the training, participants receive by email a personal link to the evaluation and a certificate of attendance as a PDF with a certificate number. We store the evaluation, name, course, date and certificate number; the number can be used to verify the authenticity of the certificate on our website (only name, course and date are then displayed). We only publish quotes from evaluations with your explicit consent.

4. Legal basis and storage period

Art. 6(1)(b) GDPR (enquiry, contract, certificate), Art. 6(1)(f) GDPR (quality assurance through ratings) and Art. 6(1)(a) GDPR (publication of quotes). We retain booking and invoice data for up to ten years, certificate data for ten years, and ratings for up to three years.

X. Online tools

1. Calculators

The Piping Spec Calculator, the Support Span Calculator and the other piping calculators calculate exclusively in your browser. Your inputs are not transmitted to us. For the output of the spec sheet and other results, we log the operation and the name of the piping spec in the customer account. A piping spec that you save is stored as a file on your computer; we do not store your piping specs. Queries to the ASEING manufacturer database (e.g. matching manufacturer systems for material and pressure rating) contain only technical information.

2. Catalog Checker and Catalog Builder (ASEING)

The Catalog Checker runs in your browser; your catalog files are not uploaded. Only the file name, the number of part families (for testing and billing) and, when adding families, the names of the added families are transmitted to us. When creating the Excel file or adding data to the company database, the Catalog Builder transfers the manufacturer data read from manufacturer catalogs and the selected industry to the ASEING manufacturer database – without any reference to you, your company or your project. You can opt out of this transfer at any time with the "Contribute manufacturer data" checkbox; we store this setting with your customer account.

Company database: If you add a catalog to your company database, we store the component families generated from it (not your source files) assigned to your customer account. If we have activated the shared company database at your company's request, approved customer accounts with the same company e-mail domain can see the catalogs you make visible to your company, together with your name as their creator. You can opt out of this for individual catalogs or for your account at any time. The legal basis is Art. 6(1)(b) GDPR; you delete the data yourself in the Catalog Builder, and at the latest it is deleted together with your customer account (unless, at your company's request, we first transfer a catalog to another customer account of the same company).

3. Billing and company package

We record every paid use (catalog credits) and every use within a trial with date, account, company, operation, catalog or piping spec name and number of families. A Catalog Checker package applies to the ordering company: customer accounts with the same company email domain can use it and see the package balance, the name of the person who ordered it and the names of the catalogs checked within the package.

4. Standards status notification (voluntary)

If you switch on the standards status notification in the Catalog Checker, we store the standard numbers (e.g. "DIN EN 1092-1") and the file names of the checked catalogs, up to 50 catalogs, in your customer account in order to notify you in the Catalog Checker of later changes to the standards status. We do not store dimensions, materials or the composition of your piping specs. The legal basis is your consent (Art. 6(1)(a) GDPR). You can withdraw it at any time in the Catalog Checker with "switch off and delete"; the information is then deleted.

5. Technical decisions in the Catalog Checker (voluntary)

If you leave a finding in the Catalog Checker as "Intentionally so", we note this in the check report. Only if you also tick the box "Send decision anonymously to ASEING" do we transmit the decision to us: type and wording of the finding without numbers and names, component class, proposed field and value, your justification, the confirmed professional background of your account (as weighting) and a non-reversible identifier instead of your account. We do not transmit catalog or company names. We evaluate the decisions to improve the check rules. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time with effect for the future (untick the box or email homepage@seitz-ingenieure.de). We delete the entries as soon as they are no longer needed for maintaining the rules, at the latest after three years.

6. Legal basis and storage period

Art. 6(1)(b) GDPR (use and billing), Art. 6(1)(f) GDPR (protecting the tools against misuse, including daily limits per account). We retain bookings for up to ten years if they are relevant for billing, otherwise until the account is deleted.

XI. Tool feedback

In the online tools, you can send us questions, error reports and ratings, with a screenshot if you wish. We store the message with a case number, tool, page, time, name and email address and send it by email to our website mailbox. You receive our reply by email. For standard cases, the website creates draft replies according to fixed rules; every reply is checked by us before it is sent. For technical evaluation, we may process the content of the feedback without name and email address with an AI assistant (Claude by Anthropic PBC, USA).

Legal basis: Art. 6(1)(b) and (f) GDPR (handling your request, improving our tools). We delete the cases twelve months after completion.

XII. Support appointments via Microsoft Teams

You can request support appointments via our website. We process company, name, email, telephone, program, topic and description. We check available times against our Outlook calendar; after our confirmation, we create the appointment as a Microsoft Teams meeting. For billing, we read the meeting's attendance report (join and leave times) after the appointment. The provider is Microsoft Ireland Operations Ltd., One Microsoft Place, South County Business Park, Leopardstown, Dublin 18, Ireland. The legal basis is Art. 6(1)(b) GDPR; we retain billing data for up to ten years.

XIII. Google Analytics 4

1. Description and scope of data processing

This website uses the web analytics service "Google Analytics 4" of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland ("Google"), integrated via the WordPress plugin "Site Kit by Google". Google Analytics uses cookies and similar technologies that enable an analysis of your use of our website. The information generated about your use of this website is generally transmitted to a Google server and processed there. IP addresses are not stored in Google Analytics 4.

Google Analytics is only activated on our website after your explicit consent via our cookie banner.

2. Legal basis

Your consent pursuant to Section 25(1) TDDDG and Art. 6(1)(a) GDPR.

3. Purpose

We use Google Analytics to analyze the use of our website and improve it regularly.

4. Recipients and transfers to third countries

The recipient of the data is Google. A transfer to Google LLC in the USA cannot be ruled out. Google LLC is certified under the EU-US Data Privacy Framework; an adequacy decision of the EU Commission (Art. 45 GDPR) therefore exists for the transfer.

5. Storage period

Data linked to cookies and user identifiers (event and user data) are automatically deleted in Google Analytics after 2 months; on a repeat visit, the period for the user data starts again.

6. Withdrawal

You can withdraw your consent at any time with effect for the future via our cookie settings.

XIV. schubwerk Analytics

In order to design our website according to needs, we use the analytics tool "schubwerk Analytics". When the website is accessed, this tool processes communication data (e.g. information about the device used, IP address) and stores them on the servers of "schubwerk Analytics" located in Germany. The IP address is irreversibly anonymized at the moment the page is accessed. "schubwerk Analytics" does not set cookies. No information is read from the device you use. "schubwerk Analytics" only uses data that are automatically sent by you for technical reasons when accessing the website. No conclusions about your identity are possible.

We use the analytics service on the basis of our legitimate interest in recording visitor flows on our website and providing our service in a form that enables a user-friendly experience of the online offering, Art. 6(1)(f) GDPR.

XV. Recipients at a glance

• domainfactory GmbH (website hosting, Germany) – processor
• Microsoft Ireland Operations Ltd. (email, calendar, Microsoft Teams) – processor; transfer to the USA possible, Microsoft Corporation is certified under the EU-US Data Privacy Framework

XVI. Rights of the data subject

If your personal data are processed, you are a data subject within the meaning of the GDPR and you have the following rights vis-à-vis the controller:

1. Right of access

You can request confirmation from the controller as to whether personal data concerning you are being processed by us.

If such processing takes place, you can request the following information from the controller:

(1) the purposes for which the personal data are processed
(2) the categories of personal data being processed
(3) the recipients or categories of recipients to whom the personal data concerning you have been or will be disclosed

(5) the existence of the right to request rectification or erasure of the personal data concerning you, the right to restriction of processing by the controller, or the right to object to such processing
(6) the existence of the right to lodge a complaint with a supervisory authority
(7) all available information on the source of the data if the personal data are not collected from the data subject
(8) the existence of automated decision-making, including profiling, pursuant to Art. 22(1) and (4) GDPR and – at least in those cases – meaningful information about the logic involved, as well as the significance and the envisaged consequences of such processing for the data subject.

You have the right to request information as to whether the personal data concerning you are transferred to a third country or to an international organization. In this context, you can request to be informed of the appropriate safeguards pursuant to Art. 46 GDPR relating to the transfer.

2. Right to rectification

You have the right to rectification and/or completion vis-à-vis the controller if the personal data processed concerning you are inaccurate or incomplete. The controller must carry out the rectification without undue delay.

3. Right to restriction of processing

You can request the restriction of processing of the personal data concerning you under the following conditions:

(1) if you contest the accuracy of the personal data concerning you, for a period enabling the controller to verify the accuracy of the personal data
(2) the processing is unlawful and you oppose the erasure of the personal data and request the restriction of their use instead
(3) the controller no longer needs the personal data for the purposes of the processing, but you require them for the establishment, exercise or defense of legal claims, or
(4) if you have objected to the processing pursuant to Art. 21(1) GDPR and it has not yet been determined whether the legitimate grounds of the controller override your grounds.

Where processing of the personal data concerning you has been restricted, such data – with the exception of storage – may only be processed with your consent or for the establishment, exercise or defense of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the Union or of a Member State.

If processing has been restricted under the above conditions, you will be informed by the controller before the restriction is lifted.

4. Right to erasure

a) Obligation to erase

You can request the controller to erase the personal data concerning you without undue delay, and the controller is obliged to erase these data without undue delay where one of the following grounds applies:

(1) The personal data concerning you are no longer necessary for the purposes for which they were collected or otherwise processed.
(2) You withdraw your consent on which the processing was based pursuant to Art. 6(1)(a) or Art. 9(2)(a) GDPR, and there is no other legal basis for the processing.
(3) You object to the processing pursuant to Art. 21(1) GDPR and there are no overriding legitimate grounds for the processing, or you object to the processing pursuant to Art. 21(2) GDPR.
(4) The personal data concerning you have been processed unlawfully.
(5) The erasure of the personal data concerning you is required for compliance with a legal obligation under Union or Member State law to which the controller is subject.
(6) The personal data concerning you have been collected in relation to the offer of information society services referred to in Art. 8(1) GDPR.

b) Information to third parties

If the controller has made the personal data concerning you public and is obliged to erase them pursuant to Art. 17(1) GDPR, the controller shall take reasonable steps, including technical measures, taking into account available technology and the cost of implementation, to inform controllers processing the personal data that you as the data subject have requested the erasure of all links to, or copies or replications of, those personal data.

c) Exceptions

The right to erasure does not apply insofar as the processing is necessary

(1) for exercising the right of freedom of expression and information
(2) for compliance with a legal obligation which requires processing under Union or Member State law to which the controller is subject, or for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller
(3) for reasons of public interest in the area of public health pursuant to Art. 9(2)(h) and (i) and Art. 9(3) GDPR
(4) for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes pursuant to Art. 89(1) GDPR, insofar as the right referred to in section a) is likely to render impossible or seriously impair the achievement of the objectives of that processing, or
(5) for the establishment, exercise or defense of legal claims.

5. Right to notification

If you have asserted the right to rectification, erasure or restriction of processing against the controller, the controller is obliged to communicate this rectification or erasure of the data or restriction of processing to all recipients to whom the personal data concerning you have been disclosed, unless this proves impossible or involves disproportionate effort.

You have the right vis-à-vis the controller to be informed about these recipients.

6. Right to data portability

You have the right to receive the personal data concerning you, which you have provided to the controller, in a structured, commonly used and machine-readable format. You also have the right to transmit those data to another controller without hindrance from the controller to which the personal data have been provided, where

(1) the processing is based on consent pursuant to Art. 6(1)(a) GDPR or Art. 9(2)(a) GDPR or on a contract pursuant to Art. 6(1)(b) GDPR, and
(2) the processing is carried out by automated means.

In exercising this right, you also have the right to have the personal data concerning you transmitted directly from one controller to another, where technically feasible. This must not adversely affect the freedoms and rights of others.

The right to data portability does not apply to processing of personal data necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

7. Right to object

You have the right to object at any time, on grounds relating to your particular situation, to the processing of personal data concerning you which is based on Art. 6(1)(e) or (f) GDPR; this also applies to profiling based on these provisions.

The controller will no longer process the personal data concerning you unless it can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms, or the processing serves the establishment, exercise or defense of legal claims.

If the personal data concerning you are processed for direct marketing purposes, you have the right to object at any time to the processing of personal data concerning you for such marketing; this also applies to profiling to the extent that it is related to such direct marketing.

If you object to processing for direct marketing purposes, the personal data concerning you will no longer be processed for these purposes.

In the context of the use of information society services – notwithstanding Directive 2002/58/EC – you may exercise your right to object by automated means using technical specifications.

8. Right to withdraw consent under data protection law

You have the right to withdraw your declaration of consent under data protection law at any time. The withdrawal of consent does not affect the lawfulness of processing based on consent before its withdrawal.

9. Automated individual decision-making, including profiling

You have the right not to be subject to a decision based solely on automated processing – including profiling – which produces legal effects concerning you or similarly significantly affects you. This does not apply if the decision

(1) is necessary for entering into or performing a contract between you and the controller
(2) is authorized by Union or Member State law to which the controller is subject and which also lays down suitable measures to safeguard your rights and freedoms and your legitimate interests, or
(3) is based on your explicit consent.

However, these decisions may not be based on special categories of personal data pursuant to Art. 9(1) GDPR, unless Art. 9(2)(a) or (g) GDPR applies and suitable measures have been taken to protect the rights and freedoms and your legitimate interests.

In the cases referred to in (1) and (3), the controller shall implement suitable measures to safeguard the rights and freedoms and your legitimate interests, at least the right to obtain human intervention on the part of the controller, to express your point of view and to contest the decision.

10. Right to lodge a complaint with a supervisory authority

Without prejudice to any other administrative or judicial remedy, you have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, place of work or place of the alleged infringement, if you consider that the processing of personal data concerning you infringes the GDPR. The authority responsible for us is the Hessischer Beauftragter für Datenschutz und Informationsfreiheit (Hessian Commissioner for Data Protection and Freedom of Information), Gustav-Stresemann-Ring 1, 65189 Wiesbaden.

The supervisory authority with which the complaint has been lodged informs the complainant of the progress and outcome of the complaint, including the possibility of a judicial remedy pursuant to Art. 78 GDPR.
