When you sign in with Google, Supabase stores your email address on our behalf for authentication purposes — we do not store it in our own database or use it beyond account creation. We store your display name and, if provided by Google, your profile picture URL. When you save a score, we store your game results (correct answers, time, game mode). We do not log street selections, map clicks, or any other in-game interactions. Guest players leave no data whatsoever.
Supabase — database and authentication provider. Your account data and scores are stored on Supabase-managed PostgreSQL servers. Supabase acts as a data processor on our behalf. See the Supabase Privacy Policy.
Vercel — hosting. Web requests may be logged by Vercel for operational purposes. See the Vercel Privacy Policy.
OpenStreetMap / Overpass API — street geometry data originates from OpenStreetMap (© OpenStreetMap contributors, ODbL). No personally identifiable information is sent to OpenStreetMap.
Google OAuth — if you sign in with Google, Supabase receives your Google profile name and email address on our behalf to create your account. We use your display name; your email is held by Supabase for authentication only. We do not receive your password. See Google's Privacy Policy.
Vercel Analytics & Speed Insights — we collect aggregated, anonymised visitor metrics (page views, country, browser/device type, Core Web Vitals). No cookies are set and no personal data is collected. See the Vercel Privacy Policy.
We use a session cookie to keep you signed in across page loads. No tracking or advertising cookies are set. Vercel Analytics does not use cookies.
We do not sell or share your personal data with third parties. Scores saved to the leaderboard (username, correct count, time, mode) are publicly visible to all players.
You can delete your account and all associated scores at any time from your Account page. Deletion is immediate and permanent — your profile, all scores, and all leaderboard entries are removed instantly. If you are unable to access your account, email streetguesser.noblore@gmail.com and we will process your request within 30 days.
You can download a copy of all data we hold about you at any time from the Settings tab of your Account page. You can also delete your account and all associated data there. For any other requests — including questions about what data Supabase holds on our behalf — email streetguesser.noblore@gmail.com.
