Privacy policy
Last updated: 5 August 2026
Short version: apart from an identifier for your account, the decisions you record and your preference settings, we collect nothing. We use no ad network, no analytics tool and no tracking software.
What we collect
| Anonymous account id | Created automatically the first time you open the app. No email required. It exists so your records stay visible only to you. |
| Email address | Only if you choose to make your account permanent. It is optional. |
| Decision journal | The match, market, selection, odds you entered, stake units and an optional note. You write the note — we advise against putting personal information in it. |
| Preferences | Language, odds format, whether you have seen the introduction. Stored on your device, never sent to the server. |
What we do not collect
- No advertising id, tracking cookie or fingerprinting.
- No analytics or crash-reporting SDK.
- No location, contacts, photos or device identifiers.
- On iOS we do not ask for tracking permission (ATT), because there is no tracking.
- Your data is never shared with or sold to third parties.
Why we collect it
Only to provide the service: to store your decisions, show them back to you and compute your accuracy. Never for marketing, profiling or ad targeting.
Where it is stored
On a server in Germany, in our own database. Access is restricted at the row level: a user's records can be read only by that user.
How long
Until you delete your account. When you do, your journal and account are permanently deleted and cannot be recovered.
Exercising your rights
You can delete your account and all your data from inside the app: Settings → Delete account. For access, correction or portability requests, write to the address below.
Children
This service is not intended for anyone under 18.
