KoshioPrivacy Policy
Last updated: 13 August 2026
Koshio is a game about claiming ground by running. To make it work we have to process your location and a few basic details about you. This page explains what we collect and why, who can see what, and how to delete your data.
In short: your running routes are visible only to you. Other people see your username, avatar, colour, XP and your territories on the map — not your email, not your body measurements, not the points of your route. You can permanently delete your account from inside the app; you don't need to ask us.
1. Who is responsible
Koshio is run by an independent developer. For anything privacy-related, one address: info@koshio.app
2. What we process
| Data | Why | Required |
|---|---|---|
| Email address | Account identity; sign-in and confirmation | Yes |
| Username, avatar, territory colour | Showing you on the map and in rankings | Yes |
| Country and city | Scope of the leaderboards | Yes |
| Location (GPS traces) | The game itself: territory is computed from your route | Yes |
| Height, weight, birth year, sex | Calorie estimates only | No — you can leave these empty |
| Step count | Anti-cheat (compared against distance) | No (if your device supports it) |
| Runs, territories, XP | Game results and your history | Created automatically |
| Friend connections | Friend list and filters | Only when you choose |
More about location
During a run Koshio records your location in the background too, so your route doesn't break when you pocket your phone and lock the screen. Recording starts only when you start a run and stops when you finish it. Outside of runs, your location is not tracked.
3. What others can see
Other users can only see:
- Your username, avatar and territory colour
- Your total XP and your place in rankings
- The shape and size of your territories on the map
What they cannot see:
- Your email address
- Your height, weight, birth year or sex
- The points, durations or speeds of your routes
This split isn't a promise, it's enforced in the database: personal fields are simply absent from the view exposed to other users, and automated tests verify this on every release.
4. Who we share with
We don't sell your data and we don't give it to advertising networks. There are no ads and no third-party tracking in the app. We use these providers to run the service:
| Provider | Purpose | Where |
|---|---|---|
| Supabase | Database and authentication | Germany (Frankfurt), EU |
| Google Maps | Map rendering | Google infrastructure |
| Resend | Account emails | EU (Ireland) |
| DiceBear | Avatar images | Only an avatar id is sent |
| Expo / Cloudflare | App delivery and this website | — |
5. How long we keep it
Your data is kept for as long as your account exists — run history only means something if it accumulates. When you delete your account, your runs, territories, notifications and friend connections go with it.
6. Your rights
Most of them you can exercise yourself, without asking anyone:
- Correction: change your profile any time (Profile → Edit profile).
- Freeze: Settings → freeze account. You disappear from the map, the rankings and friend search; nothing is deleted. Signing in again restores it automatically.
- Permanent deletion: Settings → delete account. Irreversible; all your data goes with it.
- Access and portability: for a copy of your data, write to info@koshio.app.
If you are in the European Union your GDPR rights apply, and if you are in Türkiye your KVKK rights apply; use the same address.
7. Children
Koshio is not directed at children under 13 and we don't knowingly collect data from them. In the European Union the applicable age can be up to 16 depending on the country. If you notice your child has an account, write to us and we'll delete it.
8. Security
Connections are encrypted (HTTPS) and your session is stored encrypted on your phone. The database enforces row-level rules so each user can only reach their own data. That said, no system is one hundred percent secure and we don't claim otherwise.
9. Changes
If we update this text we'll change the date at the top. For significant changes we'll also tell you inside the app.
Note: this text was written to be plain and accurate, but it has not been reviewed by a lawyer.
