PRIVACY POLICY
Effective September 17, 2026 · Applies to the Zanshin app for iOS and Android, published by Nervous Penguin Studios LLC ("we", "us").
Zanshin is a game, not a data business. We do not require an account, we do not collect your name, email, or contacts, and we do not sell personal data. Here is everything that actually happens:
DATA STORED ON YOUR DEVICE
Your progress (levels completed, scores, streaks, badges, settings, and suspended runs) is stored locally on your device. It is not uploaded anywhere. The one exception is the optional Community feature, described below.
GAME CENTER AND PLAY GAMES
If you are signed into Apple's Game Center (iOS) or Google Play Games (Android), your scores are submitted to that platform's leaderboards under its identity, governed by Apple's privacy policy or Google's privacy policy. We receive no personal information from this.
COMMUNITY LEVELS AND CHALLENGES
The Community section is optional; nothing here happens until you open it. When you do, the game creates an account for you on Google Firebase, identified by your Game Center or Play Games player name. If you use the Community, we store the levels you publish, the levels you like, your scores on community leaderboards, the challenges you send and receive, and a device token used to deliver challenge notifications. Published levels and leaderboard entries are visible to other players under your player name. Challenges work across platforms, so a player name from one platform can be seen by players on the other. You can delete this account and its data at any time from Settings inside the game, and it is all we hold: there is no email, no password, and no profile beyond the player name your platform provides.
ADVERTISING
The free version of Zanshin shows ads served by Google AdMob. AdMob may collect device identifiers (such as the advertising identifier), approximate location derived from IP address, and ad interaction data to serve and measure ads, as described in Google's privacy policy and how Google uses data from AdMob.
- In the EEA and UK, we ask for your consent before any ad is requested, using Google's consent framework. You can change your choice any time from the game's settings.
- On iOS, we ask your permission before the advertising identifier is used, through Apple's App Tracking Transparency prompt. If you decline, you still see ads, but they are not personalized. You can change your choice at any time in iOS Settings, under Privacy & Security and then Tracking.
- Purchasing the supporter pack removes all advertising, and with it all AdMob data collection.
PURCHASES
In-app purchases are processed entirely by Apple or Google, depending on your platform. We receive no payment details. Your entitlement (ads removed, soundtrack unlocked) is stored on your device and restorable through your Apple ID or Google account.
CHILDREN
Zanshin does not knowingly collect personal information from children. Advertising is configured through Google's tools in accordance with applicable law.
CHANGES
If this policy changes, the new version will be posted at this address with an updated effective date.
