Privacy Policy

Last updated: 19 July 2026

This English translation is provided for convenience. In case of any discrepancy, the Turkish version prevails.

StampWorld ("the app") is a mobile application that lets travellers record the places they visit with GPS and photo verification, collecting a digital passport and badges. This policy explains what data we collect, why, and what your rights are.

Data We Collect

Country (chosen at sign-up)Local leaderboardUntil the account is deleted
Task completion records (location, date, points)Passport, badges, leaderboards, statisticsUntil the account is deleted
Momentary location (only during verification)Checking proximity to the task locationNot stored — used only at the moment of verification to compute distance; no raw location history is kept

Profile photo (optional)Shown on your profile, leaderboards and friend listsUntil you change it, remove it, or delete your account (applies when the profile photo feature is enabled)
Friend connectionsFriend list and friends leaderboardUntil the account is deleted
Location where a task photo was takenVerifying the photo was really taken at that location (moderation)Together with the photo for 7 days, then deleted automatically
Notification identifier (push token)Delivering notifications such as friend requests to your deviceUntil the account is deleted (removed if you turn notifications off)
Advertising identifierShowing rewarded ads (Google AdMob)Kept on your device; used only with your consent — requested via App Tracking Transparency on iOS and a consent screen on Android

Photo retention: Task photos are kept for 7 days for moderation purposes only and are then deleted from the server automatically. Your profile photo is persistent: it is kept until you change it, remove it, or delete your account — deleting your account also permanently removes your profile photo from the server. Uploaded photos may be reviewed and removed by us following a report of inappropriate content.

What we do not collect: No background location tracking (location is only accessed with "while in use" permission). We do not access your contacts, messages or other data on your device. Your data is never sold to third parties. We use Google AdMob to show ads; if you consent, your advertising identifier is shared with AdMob for that purpose only — this is not a sale, and you can withdraw consent at any time in your device settings.

Location Use

Your location is accessed only at the moment you verify a task, with "while using the app" permission. The coordinate obtained is used momentarily to compute your distance to the task point and is not saved. The only thing recorded is that the task was completed (task ID + date).

Where Your Data Is Stored

All data is stored on Supabase infrastructure hosted within the European Union (Frankfurt, Germany) and encrypted in transit (TLS).

Visibility of Your Data

Your display name and total points are shown to other users on the global/local leaderboards. Your badges and basic statistics are visible only to your mutually accepted friends. Your visit history (which locations you have travelled to) is never shown to any user.

Your Rights (KVKK / GDPR)

Access and rectification: You can change your name inside the app.
Deletion: Via Profile → Settings → Delete Account you can permanently delete your account and all of your data (completions, badges, friendships, points). This action is irreversible and immediate.
Portability and other requests: You can reach us at the contact address below.

Children's Privacy

StampWorld is not directed at users under 13 and does not knowingly collect data from this age group.

Changes

When this policy is updated, the date in the header is refreshed; significant changes are announced inside the app.
