Privacy Policy
Jumper Jack · by amgdev · Last updated 1 November 2026
Jumper Jack is a game for iPhone made by amgdev ("we"). This page explains what information the game uses and why. The short version: the game has no accounts, does not track you, and does not sell your data.
What stays on your phone
Your progress (levels cleared, coins, power-ups, best scores, achievements and settings) is saved only on your device. We don't run any server that receives it, and deleting the game deletes it.
Game Center
If you sign in to Apple's Game Center, your scores and achievements are sent to Apple so they can appear on leaderboards with your Game Center nickname. Game Center is run by Apple under Apple's Privacy Policy. We never see your Apple ID or email. You can play without signing in.
Advertising
The game shows ads from Google AdMob: optional rewarded ads you choose to watch, and occasional ads between levels. We ask Google for non-personalised ads only, rated for general audiences. The game does not ask to track you and does not use your device's advertising identifier.
To show and measure ads, Google may still process limited information such as your device type, operating system, app version, a device identifier (not the advertising identifier), approximate location derived from your IP address, and how you interact with the ads. Google may link this information to an identifier to show and measure ads, but it is not used to track you across other companies' apps and websites. Google handles this under its Privacy Policy and How Google uses information from apps that use its services.
Purchases
In-app purchases (such as Remove Ads and coin packs) are handled entirely by Apple. We never receive your payment details. The game only learns which item was bought, so it can deliver it and restore it. To help protect children, the game allows at most one coin or booster pack per day.
What we don't do
- No accounts, logins or sign-up forms.
- No analytics or tracking tools of our own.
- No selling of personal information, and no sharing beyond what Google's ad service processes as described above.
- We never ask for or read your precise location, contacts, photos, camera or microphone.
Children
Jumper Jack is suitable for all ages. We don't knowingly collect personal information from anyone, including children, and the ads are limited to general-audience content.
If you email us, we use your message and address only to reply to you.
Changes
If this policy changes, we'll update this page and the date at the top.
