Number Tower: Privacy Policy
Effective 14 October 2026
Number Tower ("the game") is a mobile math game published by vlodargames ("we"). This page explains what information is handled when you play, who handles it, and what choices you have.
The short version
- The game has no sign-up. We do not ask for your name, email address, phone number or contacts.
- Your progress, currency, city and settings are saved on your device.
- For leaderboards and online duels the game creates an anonymous player ID and stores your chosen nickname, your scores and your duel rating on our game server (hosted by Supabase).
- The game shows ads and sells optional items. The companies that provide the ads and process the purchases receive some technical data from your device, described below.
Data saved on your device
Best floors, currency, city upgrades, unlocked towers, the daily tower result and settings (sound, mode) are stored in the game's local storage on your device. It is deleted when you clear the game's data or uninstall the game.
Leaderboards and online play
When the game starts it signs in anonymously to our game server: a random player ID is created, with no name, email or password. The server stores, under that ID:
- the nickname you type in (shown to other players on leaderboards and in duels; it can be anything, it does not have to be your name),
- the results of your runs submitted to leaderboards (tower, mode, floor, score, date),
- your duel rating and the outcome of online duels.
During an online duel your correct and wrong answers are sent to your opponent in real time so both towers can be shown. No message or chat is exchanged. The server is provided by Supabase in the European Union (Frankfurt). The player ID is tied to the game's data on your device; uninstalling the game or clearing its data creates a new ID the next time you play. If you want your nickname and scores deleted, email us your nickname and we will remove them.

- On Android you can reset or delete your advertising ID in Settings > Privacy > Ads.
- Buying "No ads" or "All towers + no ads" in the game removes the ad breaks. Rewarded videos (Continue, Double rewards) are always optional.

The game is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the game, contact us and we will help to have it removed.
How long data is kept
Leaderboard results, nicknames and ratings are kept on our server for as long as the leaderboards exist, or until you ask us to delete them. Data held by Google and RevenueCat is kept according to their policies. Purchase records are kept as long as needed to restore your purchases and to meet legal obligations.
Your rights
Depending on where you live, you may have the right to access, correct or delete your personal data, to object to its use, and to complain to a data protection authority. For data on your device, clear the game's data or uninstall the game; for advertising, reset your advertising ID; for your nickname and scores, email us. For anything else, write to us and we will help, including passing your request to the services listed above.
Changes
If this policy changes, the new version will be published on this page with a new effective date.
