Privacy Policy
Upfling: Tower Jump Climber. Last updated 12 November 2026.
This policy covers the game Upfling: Tower Jump Climber, both the Android app (package name app.upfling) and the web version at upfling.app. "We" means the developer of Upfling.
In short: the game has no accounts, no ads, no analytics and no tracking. It works without sending us anything that identifies you. If you choose to post a nickname to the world leaderboard or use invite codes, a small amount of data is sent so those features can work.
Data kept on your device
Your settings, best runs, medals, unlocked characters and a randomly generated id are stored on your device only. We cannot see them. Reset in the game's Settings erases your runs, medals and unlocks. Clearing the app's data or uninstalling it erases everything, including the random id.
Data sent to us, and when
- World leaderboard (optional). If you choose a nickname, the game sends that nickname, the floor, score, combo and character of your best run, and the random id. The nickname and run are shown publicly on the leaderboard.
- Invite friends (optional). If you open the Invite screen, the game sends the random id to create your invite code and to count friends who join with it. If you enter a friend's code, the game sends your random id and that code.
- Reporting a name (optional). If you report a name on the leaderboard, the game sends that name and your random id, so we can review the report and limit misuse. The name is also hidden on your device.
- Rank lookup. After a run the game asks our server where that floor and score would rank. This request carries no nickname and no id.
The random id is created by the game. It is not your phone's advertising id or any hardware identifier, and it is not linked to your name, email, phone number or Google account.
The game does not collect your location, contacts, photos, files, microphone, camera, purchase history or advertising id. If you turn on tilt controls, motion sensor readings are used on the device to move your character and are never sent anywhere.
How the data is used
Only to run the features above: showing the leaderboard, ranking your run, limiting spam and inappropriate names, reviewing reported names, and unlocking characters through invites. We do not use it for advertising or profiling.
Who the data is shared with
We do not sell your data or share it with advertisers or data brokers. Two service providers process it on our behalf:
- Supabase hosts the leaderboard and invite database.
- Cloudflare hosts the website upfling.app.
As with any internet service, these providers see the IP address of each request and may keep short-lived technical logs for security and reliability. We do not store your IP address with your leaderboard entry and do not use it to identify you.
Security
All data is sent over an encrypted connection (https). Access to the database is restricted, and the game can only read and write through limited functions.
How long we keep it
Your leaderboard entry and invite code are kept until you ask us to delete them or the game is shut down. Reports of names are kept while they are reviewed and as a record of what was decided.
Deleting your data
To delete data on your device, clear the app's data or uninstall the app. To delete your leaderboard entry and invite code from our server, contact us with the nickname shown on the leaderboard. We will remove it within 30 days.
Children
Upfling is not directed at children under 13. The game asks for no personal information beyond an optional nickname. Nicknames are filtered, and any player can report a name from the leaderboard screen. If you believe a child has posted personal information as a nickname, contact us and we will remove it.
Contact
For privacy questions or deletion requests, email hello@upfling.app.
