This Privacy Policy describes how ProstHub processes personal data when providing our B2B platform for digital QR menus, TV signage and AI-assisted content.
1. Controller and Contact
- Controller:
- Bilal Saglam
- Freelancer Softwareentwickler — ProstHub
- Kohlenstraße 105, 34121 Kassel, Germany
- Email: info@prosthub.com
2. Scope of Processing
- This Policy applies to users of our B2B Service (e.g., venue admins). Guests who view a public QR menu generally do not need to provide personal data.
3. Categories of Data
- Account and business contact data (name, email).
- Content you provide (menu items, photos, logos, captions); this is typically business data.
- Billing data processed by Stripe (see Stripe’s privacy notices).
- Technical data: server logs (IP address, timestamps, user agent) for security and diagnostics.
- AI inputs/outputs you submit for generating tasting notes, captions and images.
4. Purposes and Legal Bases
- Contract performance (Art. 6(1)(b) GDPR): account creation, hosting menus, signage, AI text/images.
- Legitimate interests (Art. 6(1)(f) GDPR): service security, abuse prevention, product improvement.
- Legal obligations (Art. 6(1)(c) GDPR): invoicing, tax and compliance requirements.
- Consent (Art. 6(1)(a) GDPR): only where we ask for it (e.g., non-essential cookies, marketing).
5. Processors and Transfers
- Hosting on Google Cloud (EU regions where feasible).
- Payments via Stripe.
- Additional sub‑processors may be used to provide features; a current list is available on request.
- We do not sell personal data.
6. Storage Period (Retention)
- We store account and venue content for the life of the subscription.
- Backups/logs are retained for limited periods needed for security and operations.
- After termination, upon request and where feasible, a data export of menu data can be provided within 30 days; thereafter, data may be deleted or anonymised unless legal retention applies.
7. Your Rights (GDPR)
- Right of access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction (Art. 18), portability (Art. 20), and objection (Art. 21).
- You also have the right to lodge a complaint with a supervisory authority (in Germany, e.g., HBDI Hessen).
- As our Service targets B2B customers, these rights primarily concern natural persons whose data may be processed (e.g., admin users).
8. Security
- We use technical and organisational measures appropriate to the risk, including least‑privilege access, encryption in transit, and regular updates.
9. Cookies and Analytics
- MVP: we use only essential cookies required for authentication/session where applicable.
- No marketing/advertising cookies are used by default. If we add non‑essential cookies or analytics, we will request consent where required.
10. Changes to this Policy
- We may update this Policy to reflect changes to our processing. Significant changes will be notified via email or in‑app notice.
