2. Quick answers
Where is my progress saved?
On your phone only. The Game has no accounts, no sign-in and no cloud save. If you uninstall the Game or clear its data, the progress is gone, and we cannot restore it. Your phone’s own backup (Google or Apple) may restore it, depending on your device settings.
I got a new phone. Can I move my progress?
Not by ourselves: there is no account to sign in to. If your old and new phone share a system backup, the Game’s data may come with it.
Is the BTC in the Game real?
No. All currencies in the Game are virtual, have no real-world value and cannot be withdrawn or exchanged. See the Terms of Use.
The Game says there is no video right now.
Rewarded videos depend on your connection and on what advertisers have available at that moment. Check your internet connection and try again a little later.
Can I turn ads off?
The Game is free and supported by ads. Rewarded videos are always optional. You can reset or switch off personalised ads in your phone settings: see section 5 of the Privacy Policy.
How do I switch notifications off?
The reminders are scheduled by the Game on your phone. Switch them off in the system settings of your phone (notifications for Mining Fever).
Which language does the Game use?
The language of your phone, if the Game has it (English, Russian, Spanish, Portuguese, German, French, Turkish, Japanese or Arabic), otherwise English.
3. Delete your data
The Game has no accounts, so there is no account to close. What exists, and how to delete it:
- On your phone. Your progress, miner name and settings are stored in the Game’s private storage on your device. Uninstalling the Game deletes them, and so does clearing its data on Android (Settings → Apps → Mining Fever → Storage → Clear data). On iOS, delete the app (touch and hold its icon → Remove App → Delete App). We do not receive them and cannot restore them.
- At the services built into the Game. Analytics, attribution, A/B tests and advertising services (listed in section 4 of the Privacy Policy) may hold technical data linked to random identifiers, for example the advertising ID of your device. To ask for it to be deleted, write to support@tefs.com with the subject “Delete my data” and give us what we can search by:
- Android: the advertising ID from Settings → Privacy → Ads. If you deleted or reset it (section 5 of the Privacy Policy suggests this), send the same as for iOS below: the model of your phone, the version of the Game, the approximate date you installed it and the date you last played.
- iOS: the system does not show you the advertising identifier (IDFA), and the Game and its services receive it only if you allowed tracking in Settings → Privacy & Security → Tracking (if you declined, they do not, see section 5 of the Privacy Policy). Send instead the model of your iPhone, the version of the Game, the approximate date you installed it and the date you last played.
- At advertising networks. Data held by the advertising networks that show ads in the Game is deleted by contacting them through the links in section 4.4 of the Privacy Policy.
We answer within the time the law requires. Your other rights, and the steps to reset or limit advertising identifiers, are in sections 5, 8 and 9 of the Privacy Policy. Starting over (clearing the data or reinstalling) creates new random identifiers, and we do not link new data to the old.
