Privacy policy
Idol Star does not collect any data about you. It has no account system, no servers, and no code that sends anything anywhere. Your run is saved as one small file on your own phone, and that is the only place it exists.
What we collect
Nothing. The app contains no analytics service, no advertising libraries, no crash reporting service, no in-app purchase libraries and no social or sign-in integrations. It does not ask for your name, your email address, your contacts, your location, your photos, your microphone or your camera. It does not read your advertising identifier or any other device identifier.
The app has no networking code at all. On Android it does not declare the
INTERNET permission. The only system feature it uses is the one
that tells it where its own private storage folder is, so it can write your
save file there.
What the app stores on your device
One file, run.json, inside the app's own documents folder.
It is unusually small, because of how the game is built: the game is
deterministic, so instead of saving the state of your run it saves the
instructions for rebuilding it, and replays them when you come back.
The whole file is three things:
- a seed — one number the game uses to decide what happens
- the name you typed for your character
- the list of choices you tapped, in order
That is all of it. There are no statistics in the file, no timestamps, no device information and no identifiers. It is plain readable JSON and you can open it with any text editor. None of it is transmitted.
The name you type is treated as a character name, not as your name. It is never sent anywhere and never shown to anyone else, because there is nobody else in the app.
The game's content — every event, every line of writing — ships inside the app as a bundled file. Nothing is downloaded at runtime, so there is no request to a content server and nothing to log.
Device backups
Because the save lives in the app's documents folder, it is picked up by your phone's normal backup: Android Auto Backup on Android, and device or iCloud backup on iOS. That is deliberate, so reinstalling the app does not delete a run in progress. Those backups are handled by Apple and Google under their own privacy policies and your own backup settings. We cannot see them, and we have no way to read your save.
Accounts, online play, leaderboards
There are none. There is no login, no friends list, no chat, no cloud save and no online leaderboard. The other characters in the game — the other trainees, the trainers, the company — are invented by the game. They are not other people and they are never presented as other people. The entire game works with the phone in aeroplane mode.
If online features are ever added, this page will be updated before they ship and the store listing's privacy answers will be redone to match.
Advertising and purchases
The app contains no advertising and no in-app purchases. There is no ad network in the build, so there is no ad profiling, no App Tracking Transparency prompt and nothing to opt out of. Nothing in the game can be bought, and no outcome can be paid for.
Sharing a run
The screen at the end of a run has a Copy run button. It puts a short summary of your run, and its seed, onto your device's clipboard so you can paste it somewhere yourself if you want to. It sends nothing on its own, and we never see it. What happens to it after you paste it is up to you and the app you paste it into.
Deleting your data
Uninstalling Idol Star deletes the app's documents folder, and with it the save file. There is nothing left on a server, because there is no server.
Two things to know:
- Your phone's backup may still hold a copy of the save after you uninstall. Clearing that is done in your device's backup settings, not in the game.
- Starting a new life replaces the existing one. There is one save, and beginning again overwrites it.
Children
Idol Star is rated 12+ and is not directed at young children, but little of that matters here: the app collects no personal data from anyone, of any age. There are no ads, no purchases, no chat, no user profiles and no way for one player to see another player's content. Nothing a child types into the game leaves the device.
We do not knowingly collect personal information from children, because we do not collect personal information at all. If you believe something in the app contradicts this, please write to the address below and we will fix it.
Your rights
Data protection law gives you rights to access, correct, export and delete personal data held about you. We hold none, so there is nothing for us to hand over or erase. Your save file is yours, on your device, and you can read it with any text editor.
Changes to this policy
If the app starts doing something this page does not describe — analytics, ads, purchases, cloud save — this page is updated first, with a new date at the top, and the store privacy forms are updated with it. We will not quietly add collection under an old policy.
