Domino Dominion — Private Beta Privacy Notice
Last updated: 21 August 2026. This is a private, invite-only test build.
Who this is. Domino Dominion is an early test version of a dominoes game. This notice explains what data the beta collects and who processes it. Questions or deletion requests: cledet@calcoenterprises.us.
How you get in, and the one thing we know about you. The beta is invitation-only. To invite you, we add your email address to an access allowlist operated by Cloudflare, which emails you a one-time code each time you sign in. That email address is the only real-world identifying information we hold, and it is used for access control and nothing else — no marketing, no newsletters, no sharing.
Inside the game, there is no account. Once you're through the gate, the app creates a random anonymous ID for you and stores it in your browser. The game itself never asks for your name or email. If you clear your browser storage, that ID is gone and you'll get a new one.
We do not connect the two. Your email lives in the access allowlist; your anonymous ID lives in the game's database. Nothing joins them.
What we collect and why
- Your email address — held in the Cloudflare Access allowlist so we can send you a sign-in code. Access control only.
- Match records — completed matches and the moves in them, stored in our database (Supabase) so the game can work and results can be reviewed. These are tied to your anonymous ID, not to you.
- Connection and hosting data — the game server runs on Colyseus Cloud and the web app is hosted by Cloudflare. Both process the technical data needed to serve the app to your device.
That's the whole list. This beta build sends no analytics and no crash reports to anyone. There is no third-party tracking, no advertising, and no session recording.
We do not sell your data, show ads, or use it for anything beyond running and improving this beta.
Deletion, and what we can honestly promise
You can ask us to delete your data at cledet@calcoenterprises.us.
Two parts, and they work differently:
- Your email — we can remove it from the access allowlist completely. That also ends your access to the beta.
- Your match data — we can only delete this while the anonymous ID still exists on your device, because that ID is the only link between you and those records. Once it's cleared, we genuinely cannot tell which matches were yours.
We would rather say this plainly than promise something the system can't do.
Beta data may be reset. Because this is an early test, data may be deleted or reset at any time.
Other things worth stating
Not for children. This beta isn't directed to children under 13, or the equivalent age in your region.
Where this applies. Access is by individual invitation only — every tester is added to the allowlist by us, and no one else can get in. The beta is operated for testers in the United States.
Changes. If the beta's data practices change, we'll update this notice before the change takes effect. In particular: if we later add analytics or crash reporting, this notice will say so first.
