Delete your data
For Momentum, and for every game published by Ludavia.
Last updated 12 September 2026.
The short version. Uninstalling the game deletes everything it kept on your phone, at once. For the little that advertising and analytics send to Google, write to contact@ludavia.games and we will have it deleted. Nothing we hold carries your name, because the game never asks for it.
Step 1, what you can delete yourself, right now
Uninstall the game. Your progress and your settings live in the app's own private storage. They go with it, immediately and completely, and no copy of them exists anywhere else.
Or erase only your progress without uninstalling: open the settings inside the game, choose to reset your progress, and confirm. It takes two taps and it is irreversible.
Reset your advertising identifier. In Android, go to Settings, then Privacy, then Ads. You can reset or delete the identifier there. It applies to every app on the phone, not only ours.
Step 2, ask us for the rest
Write to contact@ludavia.games with Delete my data as the subject, and tell us which game you played and roughly when.
We answer within 30 days, in English or French. There is nothing to prove and no account to close: we will ask you for nothing more than the message itself.
This policy was written in English. The other versions are translations; where they differ, the English version is the one that governs.
Why we may ask for a date. The game has no account and no login, so we hold no name, no email address and nothing that identifies you. What reaches Google carries a random identifier tied to your installation, not to you. That is good for your privacy and awkward for a deletion request: it is the reason a rough date helps us find and remove the right records.
What is deleted, what is kept, and for how long
| Data | Where it is | What happens |
|---|---|---|
| Your progress and settings | Your phone only | Deleted when you uninstall, or from the settings screen. We never receive a copy. |
| Game events: the tier you reached, a level left, an error that did not crash the game | Google Analytics for Firebase | Deleted automatically after two months, the shortest period the service allows us to set. Deleted sooner on request. |
| Crash reports | Firebase Crashlytics | Kept for the period Google applies, then deleted. Deleted sooner on request. |
| Advertising data | Google AdMob | Held by Google under its own policy. Reset your advertising identifier to break the link, and see how Google uses it. |
Nothing else exists. No name, no email address, no contacts, no photos, no messages, no files, no financial data, no precise location.
Refusing rather than deleting
You can also stop the collection instead of erasing it afterwards. In the European Economic Area, the United Kingdom and Switzerland, a consent message appears before anything is sent, and you can change your answer at any time from the game settings. A refusal stops the analytics events and the crash reports, not only the personalised ads.
