Privacy policy
This is a translation. If the two versions differ, the Czech version applies.
1. Who processes your data
The data controller is David Pavelek, Company ID (IČO) 29973431, registered at Vysoká 940/8, Litice, 321 00 Plzeň, Czech Republic ("we"). He is the author and operator of the game Perimeter Control.
Contact for all questions about personal data: perimetercontrol.game@gmail.com.
2. What data we process and why
The game is built on location: you claim territory by walking a loop outside. Without location the game cannot work.
| Data | What exactly | Why we need it |
|---|---|---|
| Location | precise GPS location during an active expedition, including while the screen is off (background location) | to record the expedition route and calculate the claimed territory |
| Routes and territories | route points of expeditions and loops, time, distance walked, shape and area of your territories, buildings | to save your progress and show territories on the map |
| Account | nickname, colour, a random account identifier and a hash of a secret key that stays on your phone | to recognise your phone without an email or password |
| Technical data | IP address and request details when connecting to the game server and the map server | to deliver game data and maps to your phone |
| Tester application | name or nickname, Google account email, phone model, area where you move around, Discord name, questionnaire answers | to invite you to testing and communicate with you |
What we do not collect: email or password in the game, device identifiers, contacts, analytics or crash reports.
What other players see: the shape of your territories, your nickname and colour. They see the day a territory was claimed, rounded; only you see the exact time. No one else sees your routes or current location, except during a group expedition (below).
Location outside expeditions: we record location only during an active expedition. When you end the expedition, recording stops. In-game notifications are created on your phone and are not sent through any third-party service.
Group claiming (coming soon): if you join a group expedition, the other members of that group see your current location and you see theirs.
- only members of the group see the location, no one else,
- it is shared only during the joint expedition and stops immediately when it ends or when you leave the group,
- you join a group yourself and can leave it at any time,
- we do not store the movement history of other members; only the current location is shared.
We do not sell personal data and do not use it for advertising.
3. Legal basis
- Performance of a contract (Art. 6(1)(b) GDPR): location, routes, territories and account. We cannot provide the game without them.
- Legitimate interest (Art. 6(1)(f) GDPR): technical data for fixing bugs and preventing cheating, such as fake location.
- Consent (Art. 6(1)(a) GDPR): data from the tester application. You can withdraw consent at any time by email.
You always grant location access in your phone's settings and can revoke it there at any time.
4. Who receives the data
We share data only with those who help us run the game:
| Recipient | Why | Where the data is |
|---|---|---|
| the operator's server | storing game data; during testing it runs on the operator's computer | Czech Republic |
| ngrok, Inc. | secure connection (tunnel) between the app and the server; all game traffic passes through it | USA |
| OpenFreeMap (Hyperknot Software Kft.) | map tiles; receives your IP address and the map area you view | Hungary (EU) |
| Google (Google Play, Google Forms) | game distribution, tester applications | EU and USA |
| Discord | communication with testers, if you join | USA |
Transfers to the USA rely on the EU–US Data Privacy Framework or standard contractual clauses. We share data with others only when the law requires it.
5. How long we keep data
| Data | Retention |
|---|---|
| Account, territories and game data | while the account exists; deleted immediately when the account is deleted |
| Expedition and loop routes on the server | 30 days, then deleted automatically |
| Unclaimed route line | 24 hours |
| Technical connection data | not stored permanently |
| Tester application | until the end of testing, at most 12 months, or until consent is withdrawn |
We may reset data from the test version before the official release. We will tell you in advance.
6. Your rights
You have the right to:
- find out what data we hold about you and get a copy,
- have incorrect data corrected,
- have data deleted,
- restrict processing or object to processing based on legitimate interest,
- receive your data in a machine-readable format (portability),
- withdraw consent at any time,
- lodge a complaint with the Czech Office for Personal Data Protection (uoou.gov.cz) or the authority in your country.
Just write to perimetercontrol.game@gmail.com. We reply within 30 days.
7. Deleting your account
Delete your account in the game: Profile → Delete account. The account and all its data, including routes and territories, are deleted immediately. In your profile you can also delete only your routes on the server or the history on your phone and keep the account. If you can't get into the game, email us and we'll delete the account for you.
8. Children
The game is intended for people over 15. Younger people may use it only with the consent of a parent or legal guardian. If we find that an account belongs to a child without such consent, we delete it.
9. Security
The app communicates with the server encrypted over HTTPS. You don't log in with a password: your phone holds a random secret key and the server knows only its hash, so the key cannot be misused even if server data leaks. Only the game operator has access to the server.
10. Changes to this policy
We may update this policy, for example when the game gets new features. We will inform you of significant changes in the game or by email. The current version is always on this page.
