Privacy Policy

Last updated: 5 October 2026. This site is CrowdSweeper (crowdsweeper.app) — a shared, real-time Minesweeper game. There are no accounts and no logins.

What we collect

Game activity: anonymous board moves, flags and events. These contain no personal data.
Chat: the display name you pick (randomly generated or self-chosen) and the messages you send. Chat is public — anyone can read it, so don't share personal details there.
Cookies: a random player identity and your cookie choice are stored in your own browser only. We do not store personal profiles on our side.

Advertising and measurement (Google)

Who receives data: Google LLC (Google AdSense for adverts, Google Ads for measuring advert performance).
Purposes: showing adverts on this site, and measuring advert clicks and conversions.
Data used: cookies and identifiers in your browser, such as advertising identifiers, page views and ad interactions.
In regions that require consent (European Economic Area, UK, Switzerland), these cookies stay switched off until you press Accept on the cookie banner. If you press Decline, adverts may still appear but are not personalised and no measurement is recorded.
You can change your choice any time with the Cookie settings link on the game page, clear the stored choice in your browser, or manage Google ad personalisation at adssettings.google.com.

How to remove your data

Because there are no accounts, there is nothing to delete from your side beyond what your browser stores: clear your browser storage for this site, and use the Cookie settings link to withdraw your advertising consent at any time.
