Gexmark is a real-world exploration game: you uncover the map by physically moving. This policy explains what data we process and why. We collect the minimum.
A cell you open appears on the shared world map. If you opened it first, your nickname is shown next to it as the discoverer — that's part of the game. Your exact route is never visible to other players.
We do not sell your data and do not share it with advertisers. There are no ads in the app. Data is stored on our servers in the European Union (Germany), transmitted over HTTPS, and used only to run the game.
When you purchase the Friend of Gexmark pack or request support, we process the game ID, purchase reference, payment confirmation, amount and date, and the contact information and messages you provide. We use these details to verify and deliver the pack, restore the appearance and handle refunds or disputes. Information is kept for these purposes and any legally required record-keeping period. Payment details are entered with the payment service; we do not receive or store full card details or security codes. Purchases currently take place on Boosty under its own data processing terms.
To understand which versions of Gexmark are used and improve compatibility, the app sends a small technical report to our own server, normally once a day while the app is open and additionally after an update or account change. It contains the game account ID, a random installation ID, app version, build variant, installer reported by Android, Android API version, and server receipt time. The report contains no coordinates, route, advertising ID or hardware identifier. The installation ID changes after a reinstall and is excluded from Android backups. These details are visible only to the administrator. Activity summaries and technical reports are retained for up to 90 days and are removed when you delete your game account. No third-party analytics SDK receives this report.
The gexmark.online homepage uses Yandex Metrica (counter 114057113) to measure visits and clicks on Google Play, RuStore and Telegram links. Yandex may process cookies, IP addresses, browser and device information, the page address and referral source for website statistics. Webvisor session recording and click maps are disabled in our integration. We do not send game account IDs, private exploration history or GPS routes to this counter. This is separate from the app technical reports described above. See Yandex Privacy Policy.
If you choose to verify Telegram community membership for an achievement, we link your game account ID with your numeric Telegram ID. Our dedicated bot checks your membership with Telegram at your request. An existing member can also verify. One Telegram account can confirm one game account. Temporary verification links expire; completed achievements remain earned. The Telegram link and unfinished verification requests are removed when you delete your game account.
You can delete your account right in the app (Settings → Delete account). On deletion, your identity is erased (nickname, Google/Yandex/email sign-in links, coins) and sign-in becomes impossible. Your trace on the shared world map (opened cells) is kept anonymized — as an “unknown explorer” — because the world record is permanent. If you can't access the app, you can request deletion by emailing gexmarkgame@gmail.com. You can pause recording at any time.
Precise location (ACCESS_FINE_LOCATION), background location for
recording with the screen off, notifications, and optional physical activity recognition
(ACTIVITY_RECOGNITION) — processed on the device only, to save battery while you are
still. Without location the game does not work — it's the whole point.
The game is not intended for children under 13 and does not knowingly collect their data.
We may update this policy; the current version is always available at this address with its effective date.
