Privacy Policy
This is a browser game with no sign-up. We collect only the minimum data needed to run the game and improve its levels.
What we collect
| Data | Details |
|---|---|
| Anonymous device identifier | A random ID generated in your browser on first launch, used to link progress to this device. It does not contain and cannot reveal your identity. |
| Game progress | Cleared levels, stars and harbor repair state, used for cloud saves and for moving to another device with a recovery code. |
| In-game events | For example level started / completed / failed, hint used, rewarded ad watched, building repaired, together with the event time and game version. Used for level-difficulty and error statistics. |
| Technical logs | Our server briefly logs the IP address and browser type of requests, only for abuse prevention (rate limiting) and troubleshooting. |
Advertising
Rewarded video ads in the game are provided by Google. Google and its partners may use cookies or similar technologies to serve and measure ads; that data is handled by Google under its own policies: Google Privacy Policy, How Google uses information from sites that use its services. You can manage ad personalization in Google Ads Settings.
Hosting and traffic analytics
This site is hosted on Cloudflare. Cloudflare processes connection data such as your IP address to deliver and protect the service, and its cookie-less Web Analytics measures aggregate page views and load performance. It is not used for cross-site tracking.
What we do not collect
We do not ask for or collect your name, e-mail address, phone number, passwords, contacts, precise location, photos or payment information. The game has no registration or login.
How we use data
- to save your progress and restore it across devices;
- to compute aggregate statistics (completion rates, durations) for balancing levels and fixing problems;
- to record that an ad reward was granted, so it is neither lost nor duplicated;
- to protect the service from abuse.
We do not sell data and do not use it to identify individuals.
Retention
- In-game events: deleted automatically after 180 days;
- Game progress and the anonymous device identifier: kept until you ask us to delete them or the game is shut down;
- Recovery codes expire after 24 hours; database backups are kept for 14 days.
How to delete your data
E-mail privacy@example.com (TODO: owner to replace with the real address) with the recovery code or player ID shown on the settings page; we will delete the related progress and event data within 30 days. Clearing this site's data in your browser removes the locally stored identifier and progress.
Cookies and local storage
The game itself sets no cookies. It uses the browser's local storage (localStorage) for the anonymous device identifier, the session token, local progress and a queue of not-yet-uploaded requests. Google, as the ad provider, may set its own cookies (see "Advertising").
Children
The game is not directed at collecting personal information from children under 13. If you believe we have collected a child's data by mistake, contact us at the address above.
Changes
When this policy changes we update the effective date at the top of this page; significant changes are also announced in the game.
