GDPR compliance

ProofEU was built from day one for European companies subject to the General Data Protection Regulation. Here is exactly what we do — and don't do — with your data.

Data location

Database: Turso SQLite Cloud, Dublin (Ireland) region (EU). No automatic replication to servers outside the EEA.

Application server: Vercel Edge Network, with Dublin (Ireland) as the preferred region. European requests are processed in Europe.

File storage: No user files stored outside the EEA. Project logos are hashed and stored in the Dublin (Ireland) database.

Data security

In transit: TLS 1.3 on all connections (HTTPS enforced, HSTS enabled).

At rest: AES-256 encryption of the Turso database at the disk level.

Passwords: Hashed with bcrypt (cost factor 12). Never stored in plain text.

Tokens: Collection and access tokens are cryptographically random UUID v4 values.

Data we collect

ProofEU only collects the data necessary to run the service (data minimization):

  • The account administrator's email and hashed password
  • The end customer's name, role, company and testimonial (entered by them)
  • Testimonial creation timestamps

No third-party tracking cookies. No Facebook/Google pixel. No external behavioral analytics tool.

Data subject rights

ProofEU honors all rights granted by the GDPR (Art. 15 to 22):

  • Access and portability: CSV export of all your testimonials from the dashboard or via the API (Pro plan).
  • Rectification: Testimonials can be edited from the dashboard.
  • Erasure: Delete a testimonial or an account from the dashboard. Complete data deletion within 30 days.
  • Objection: Email privacy@proofeu.com for any request.

Data Processing Agreement (DPA)

As a processor of your customer data (the testimonial authors), ProofEU provides a Data Processing Agreement (DPA) compliant with Article 28 of the GDPR.

This agreement defines our obligations as a processor, the security measures implemented, and the procedures in case of a data breach.
