5.4. Cloudflare, Inc. is certified under the EU-US Data Privacy Framework. Further information: https://www.cloudflare.com/privacypolicy/

§ 6 – Registration and user account

6.1. The use of the platform requires the creation of a user account. The following personal data is collected during registration:

6.4. Account data is stored for the duration of the contractual relationship. After termination and expiry of any statutory retention periods, the data will be deleted (see § 21).

§ 7 – Authentication and account security

7.1. DPP Hero uses the Supabase Auth service (Supabase, Inc., San Francisco, USA) for authentication. The Supabase project of DPP Hero is operated in the EU region eu-central-1 (Frankfurt, Germany) on servers of Amazon Web Services (AWS). All database, authentication, and file storage data is stored and processed on servers within the European Union. The following data is processed during login:

(b) Session token (JWT access token and refresh token);

(c) Authenticator Assurance Level (AAL) to distinguish between single-factor authentication and multi-factor authentication;

(d) Language preference (the language selected by the user).

7.2. Two-factor authentication (2FA). DPP Hero optionally offers two-factor authentication using time-based one-time passwords (TOTP). When 2FA is activated, encrypted TOTP secrets are stored server-side at Supabase. The legal basis is Art. 6(1)(b) GDPR (performance of a contract) in conjunction with Art. 6(1)(f) GDPR (security of the user account).

7.3. Password reset. When using the password reset function, a one-time, time-limited reset link is sent to the registered email address. The legal basis is Art. 6(1)(b) GDPR.

8.3. The contact person's name constitutes personal data within the meaning of Art. 4(1) GDPR. The user ensures that the person concerned is informed about the data processing.

§ 9 – Public company profile

(a) Public company name;

(b) Business address;

(c) Website;

(d) Support email address;

(e) Contact person;

(f) Spare parts email and website.

9.2. The data from the public profile is displayed in published product passports and is therefore accessible to anyone via the internet. The user acknowledges that the data stored in the public profile becomes publicly accessible upon publication of a product passport.

9.3. The legal basis is Art. 6(1)(b) GDPR, as the provision of the public profile is a direct component of the contractually agreed platform functionality. Publication is carried out exclusively at the express initiative of the user.

9.4. The user may modify or remove the public profile data at any time via the dashboard.

§ 10 – Product data and digital product passports

10.1. The platform enables the collection, management, and publication of product data in a multi-step process (identification, materials, carbon footprint, due diligence, circularity, performance, labeling).

10.2. Product data may contain personal data, in particular:

(a) Name and address of the manufacturing facility;

(b) Information about contact persons;

(c) Contact person for spare parts.

10.3. DPP Hero processes the product data exclusively for the provision of the contractually agreed platform functions (input, storage, preview, publication, export). The legal basis is Art. 6(1)(b) GDPR.

10.4. Published product passports. Upon publication of a product passport, the product data designated as "public" is made available via a publicly accessible URL and can be accessed without authentication. Publication is carried out exclusively at the express initiative of the user.

10.5. Product images and documents. Uploaded images and documents (PDF, JPEG, PNG, WebP) are stored in publicly accessible storage areas (see § 16). The user ensures that uploaded documents do not contain personal data of third parties for which no appropriate legal basis for processing exists.

10.6. Insofar as the user enters personal data of third parties as part of the product data (e.g., contact persons, employees at manufacturing facilities), the user is the controller responsible under data protection law within the meaning of Art. 4(7) GDPR and ensures that an appropriate legal basis exists and that the data subjects have been informed in accordance with Art. 13/14 GDPR.

§ 11 – Digital signing and audit trail

11.1. The platform offers HMAC-SHA256-based integrity verification for product data. During the signing process, the following data is processed and stored:

(b) HMAC-SHA256 signature;

(c) Timestamp of the signing;

(d) User ID of the signing user;

(c) The submitted data is fully archived in the share token table.

When using a share link, no IP addresses, browser fingerprints, or other technical identifiers of the recipient are stored (without prejudice to the server log files pursuant to § 4).

(b) Product documents: Uploaded PDF files and images are stored. The file paths contain the user ID as the directory name.

16.3. Uploaded files are accessible via public URLs. This is technically necessary so that the files can be displayed in published product passports and previews. The user is advised that uploaded files may potentially be accessed by third parties if the URL is known.

16.4. When a product is deleted, the associated files are removed from storage. Upon termination of the contractual relationship, all files are deleted in accordance with § 21.

No personal data is collected; no user can be identified or re-identified across sessions. Consent pursuant to Art. 5(3) ePrivacy Directive (2002/58/EC) is therefore not required. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in the statistical analysis of website usage). Provider: Vercel, Inc., San Francisco, USA. Vercel, Inc. is certified under the EU-US Data Privacy Framework.

17.5. DPP Hero uses the Offset Website service by Tree-Nation (Tree-Nation S.A., Barcelona, Spain) for CO₂ compensation of the website.
