Dumbo Jump Privacy Policy
Effective September 27, 2026 (revised)
Dumbo Jump never asks for your name, email, phone number, or location. There is no sign-up and no password. However, the leaderboard, 1:1 races, and usage statistics do send the information listed below to a server. Here is exactly what goes where.
Anonymous sign-in
The leaderboard and races need to tell devices apart. The app gets a random anonymous ID from Google's Firebase Anonymous Authentication. No name, email, or phone number is attached to it.
What is stored on the server
The following is stored on Google Firebase (Cloud Firestore) servers:
- Nickname — the name you choose for the leaderboard (up to 12 characters)
- Endless Climb records — today's height and your all-time best, the character you used, and device type (iOS or Android)
- Race data — the movement trace of a race, finish time, nickname, character, skill total, and whether you left
- The anonymous ID attached to these records
What others can see: anyone can see the nickname, height, and character on the leaderboard. In a race, your opponent sees your nickname, character, skill total, and movement. Your fastest race of the day may appear as a ghost in other players' races.
If you never choose a nickname, nothing is posted to the leaderboard.
How long it is kept, and how to delete it
- Race rooms and race traces are deleted automatically after about a day, and ghosts after about three days.
- Leaderboard records stay until deleted.
- In the game, Leaderboard › Remove my records immediately deletes today's record, your all-time record, and your nickname. Daily records from past days are not removed this way.
- To delete everything, including past records, email us with your nickname and we will find and delete them.
What is stored on your device
The game has to remember where you left off. The following is stored on your device:
- Stars earned per stage, and which stages are unlocked
- Skill unlock progress
- Pearls, items, unlocked characters and your chosen character
- Daily check-in history
- Your best Endless Climb score and race wins/losses
- Your nickname
- Whether you bought ad removal
- Settings (haptics, sound effects, music, notifications)
Deleting the app deletes this data. You can also clear it yourself from the in-game settings. Records already on the server stay after the app is deleted, so please remove them as described above.
Usage statistics
To improve the game, we use Google Analytics for Firebase. It collects:
- Screens viewed
- Stage start, clear, and fail; boss fights; Endless Climb results; race start and result
- Shop purchases, in-app purchases (product ID only), revives, character unlocks, check-ins, and interstitial ads shown
- Your furthest stage and most-used character
- A random app-instance ID assigned by Firebase
This is not linked to your name or contact details. The advertising identifier (IDFA) is not used, and ad personalization signals are turned off. Data is collected only after the ad consent flow allows it; otherwise nothing is sent.
Currently only the iOS version sends statistics. The Android version does not.
In-app purchases
Ad removal (Ad Pass) is paid through the Apple App Store or Google Play. Payment details such as card numbers are handled by the store; the developer never receives them. The app only remembers on your device whether you bought it.
Advertising
Dumbo Jump shows ads through Google AdMob. Google may use device information to select and deliver those ads, and that processing is governed by Google's own policies.
Why we ask about tracking
On iOS, the app asks whether you allow tracking the first time you open it. If you allow it, the advertising identifier (IDFA) is used to choose more relevant ads.
Saying no changes nothing about the game. Ads still appear and no feature is locked — the ads are simply not personalised.
You can change your answer at any time.
- iOS: Settings › Privacy & Security › Tracking
- In the EEA and the UK, an ad consent form appears at first launch.
- In some US states, you can revisit the choice from Settings › Privacy options inside the game.
Sharing with third parties
We do not sell your information. The companies below process it only as needed to run the app:
- Google — Firebase (anonymous sign-in, server storage, usage statistics) and AdMob (ads)
- Apple and Google — payments through the App Store and Google Play
