Account information — When you sign up, we collect your name, email address, and a hashed password (or authentication token if you use Google Sign-In).
Page configuration — Everything you add to your love page: names, subtitles, profile photos (stored as compressed base64), start dates, love letters, Spotify playlist links, "things I love" lists, and emoji preferences.
Telegram messages — If you use the Live Messages feature, messages sent via our Telegram bot (@siriuslovebot) are stored in Vercel KV and linked to your page slug. Your Telegram chat ID and chosen password are held temporarily to verify identity.
Real-time drawing data — Canvas strokes are stored in Firebase Realtime Database, keyed by your page slug. Anyone with your page URL can view and draw on the shared canvas.
Usage data — We use Vercel Analytics to collect anonymised, aggregated page view statistics (no personal identifiers, no cookies).
