What the app stores

Ninety-Nine keeps your game progress on your device so it is there the next time you open the app:

• your best score in each game, kept separately for each mode where a game has more than one,
• your Brain Power meter and day streak,
• the date you last played, used to apply the daily decay and streak rules,
• a few game settings and records, such as the mode you last chose, the shapes collected in Perfect Center's shape book, today's Daily set, and how sharp your Stickman Battle rival has become.

This information is saved in the app's private storage on your phone or tablet. There is no account, no sign-in and no cloud sync. The result of each round is also part of the anonymous statistics below, but your saved progress stays on the device.

Anonymous gameplay statistics

To learn which games are played and where players get stuck, the app sends anonymous usage events to PostHog, our analytics provider:

• when the app is installed, updated, opened and closed,
• which screens and games are opened,
• the result of each round: the game and mode, the score, whether it was a new best, the Brain Power change and your streak, or the result of a two-player game,
• when a score card is saved or shared, and when an invite link is opened.

Each event also carries the device model, operating system, app version, language and time zone. PostHog uses your IP address to work out your country, then discards the IP address. It does not keep your city or anything more precise.

Events are tied to a random ID created when the app is first opened. It is not linked to your name, email, advertising ID or any account, and it is never used to track you across other apps or websites. PostHog stores the statistics in the United States, and they are used only to understand and improve the game.

When you are offline, events wait on your device and are sent the next time you are online. The game plays exactly the same either way.

Score cards

After a round you can turn your result into a score card: an image of your score, drawn on your device. Nothing happens to it unless you tap a button.

• Share opens your device's share sheet. The card goes only to the app or person you pick there, and what happens to it after that is up to them.
• Save adds the card to your photo library.

Ninety-Nine never sends a score card anywhere on its own. The copy it makes to share or save sits in the app's temporary cache and is cleared when you close the share sheet.

What the app does not do

• It does not show advertisements.
• It does not use advertising identifiers, cross-app tracking or fingerprinting.
• It does not record your screen, your drawings or what you type.
• It does not read your photo library, and it does not access your contacts, GPS location, microphone, camera or files.
• It does not sell your information or share it with anyone other than the analytics provider above. A score card leaves your device only when you share it yourself.

Permissions

The first time you tap Save on a score card, your device asks whether Ninety-Nine may add photos to your library. On iOS this is add-only access: the app can save the card but cannot see your existing photos. If you decline, you can still share the card. Nothing else in the app asks for a permission.

On Android the app declares VIBRATE so it can play haptic feedback when you score, and INTERNET, which it uses to send the anonymous statistics above. It also declares READ_MEDIA_IMAGES and READ_MEDIA_VISUAL_USER_SELECTED, which come with the component it uses to save images. They are used only to save a score card when you tap Save, never to read or scan your photos.

Children

Ninety-Nine is suitable for all ages. It never asks anyone, including children, for a name, email address or other contact details, and the gameplay statistics above are anonymous.

Deleting your data

Uninstalling the app deletes everything it stored on your device and resets its random ID, so future statistics cannot be connected to past ones. Score cards you saved to your photo library or sent to someone stay there until you delete them. Because the statistics are not linked to you, we cannot pick out yours, but you can email us with any questions.

Changes

If a future version of Ninety-Nine changes what it collects, this policy will be updated before that version is released.
