Privacy Policy for Speed Evolution
Last updated: 2026
Speed Evolution is an offline museum of railway speed. This policy explains, in plain language, what the app does with information. In short: it collects nothing about you and sends nothing anywhere.
1. Information we collect
We do not collect any personal information. The app has no account, no sign-in and no registration. It does not ask for your name, email address, location, contacts, photos or any other personal data.
2. Information stored on your device
To remember your visit, the app saves a small amount of information on your device only:
- your progress: which exhibits you have discovered, your favourites and your quiz scores, stored in a file inside the app's own storage;
- your settings: speed unit, haptics and timeline effects, stored in the app's local preferences.
This information never leaves your device. Your progress is removed when you use "Reset progress" in Settings, and all of this information is removed when you delete the app. It may be included in your device backups, according to your own device settings.
3. Network access
The app does not connect to the internet. All train, era and country information is included in the app itself.
4. Device capabilities
The app does not use your location, camera, microphone, photo library, contacts, health data or notifications. Haptic feedback is produced locally and can be turned off in Settings.
5. No tracking, analytics or advertising
The app contains no advertising, no analytics tools and no third-party software development kits. It does not track you across apps or websites and does not use the advertising identifier.
6. Purchases
The app contains no in-app purchases or subscriptions.
7. Children
The app is suitable for all ages. Because it collects no personal information, it collects none from children.
8. Changes to this policy
If the app changes in a way that affects your privacy, this policy will be updated and the date above will change.
