Privacy

How we handle your data

Last updated: November 11, 2026

Draft – the final text will come from our legal service.

1. Controller

Books4Memories, Büker-Meyer GbR, c/o startupdetector GmbH, Indira-Gandhi-Straße 7A, 13088 Berlin, Germany. Email: hallo@klebebotschaft.de

2. In short

No account, no tracking, no cookies. When you visit this website, we only process what is needed to run it securely.

3. Hosting

The website runs on Vercel Inc. (USA). The servers that render our pages are located in Frankfurt am Main. We have a data processing agreement with Vercel; transfers to the USA rely on the EU-US Data Privacy Framework and standard contractual clauses. The legal basis is our legitimate interest in a secure, fast website (Art. 6(1)(f) GDPR).

4. Server log files

Each request technically involves your IP address, date and time, the page requested, the referring page, and your browser and operating system – to deliver the page, find errors and fend off attacks (Art. 6(1)(f) GDPR). Log files are kept only briefly and then deleted automatically.

5. Load-time measurement

We use Vercel Speed Insights to measure how fast our pages load. Without cookies and without recognising you, it sends measurements, the page visited (sticker addresses shortened), device type, browser and country. The legal basis is our legitimate interest in a fast website (Art. 6(1)(f) GDPR).

6. Fonts

We serve all fonts ourselves. Loading a page does not connect to Google or any other font provider.

7. Purchase and payment

When you buy a sticker sheet, payment is handled by Stripe Payments Europe Ltd. (Ireland). You enter your payment details directly at Stripe; we only receive your email address, the amount and a payment reference. We store the order (email address, amount, date) for delivery, resending and statutory retention periods (Art. 6(1)(b) and (c) GDPR).

8. Delivery by email

We send the sticker sheet to your email address via Twilio SendGrid (USA). A data processing agreement is in place with SendGrid; transfers to the USA rely on the EU-US Data Privacy Framework and standard contractual clauses. We use your address only for this delivery and for “Send again”, never for advertising (Art. 6(1)(b) GDPR).

9. Contact by email

If you write to us, we process your message and email address to reply (Art. 6(1)(b) and (f) GDPR). We delete them once your request is settled and no legal retention obligations apply.

10. Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR). Just write to hallo@klebebotschaft.de. You can also complain to a data protection authority, for example the Berlin Commissioner for Data Protection and Freedom of Information.
