What this site knows about you
What we store
Your first name, and which of the four dates work for you. An email address too, but only if you asked us to tell you the result.
What we don't store
No cookies. No browser storage of any kind. No analytics, no tracking, no advertising, no phone numbers, and no IP addresses (rate limiting uses a one-way hash that is never stored in readable form).
If you tap "How far is it?" on the reveal page, we ask your browser for your location. That happens only on your device — it works out a distance and is never sent to us or stored.
Why
To pick a date for a private birthday party and to tell you what it turned out to be. Nothing else. Your answers are never sold, shared, or used for anything else.
Who else touches it
The site runs on Vercel and Supabase, both hosted in Frankfurt, Germany.
When you share your link in WhatsApp, Meta's servers fetch the preview image, and that image has your first name on it. That is the only way any of this leaves our servers.
How long
Everything is deleted automatically by 30 September 2026, a few weeks after the party. Deleted, not archived.
Who is responsible
Your rights
You can ask to see, correct, or delete your data at any time, and you don't need a reason. Message Aydin and it's done the same day. You also have the right to complain to a supervisory authority.
