Privacy Policy for Checkers

Checkers is published by Millstone Group Partners LLC and distributed through the Google Play Store and the Apple App Store. This policy covers the app on both platforms and the online play service behind it.

What we collect

Account information. Your email address and the credentials you use to sign in. You can sign in with Google or create an account directly in the app. If you sign in with Google, we receive your email address and an account identifier from Google, and we never see or store your Google password. If you create an account in the app, your email address and password are held by the authentication system of our hosting platform. We cannot read your password. You also choose a display name, which is described below.

Gameplay metrics and online play statistics. Games played, games won and lost, moves made, match duration, opponent pairings, ratings or rankings, and the timestamps of your sessions. These records make the leaderboard work, match you against opponents of similar ability, and let us detect cheating and abuse.

Technical and diagnostic data. Device model, operating system version, app version, and crash reports when the app closes unexpectedly.

We do not collect your location, contacts, photos, files, microphone, or camera. We do not collect payment information. We show no advertising and do not track you across other apps or websites.

Your display name is public

The leaderboard is visible to other players. Your display name, along with your ranking and the game statistics that produce it, appears there and can be seen by anyone using the app. Choose a display name accordingly, and do not use your full name or your email address as your display name. Everything else we hold, including your email address, stays private.

Why we collect it

Your email address identifies your account, lets you sign back in on a new device, and is how we reach you about the service, such as a security notice or a change to this policy. Gameplay statistics produce the leaderboard and the matchmaking. Diagnostic data lets us fix crashes.

We process account data to provide the service you asked for. Where the law requires consent, we ask for it. Where it does not, we rely on our legitimate interest in running a working, fair game.

Who else touches it

We do not sell, rent, or trade your data. No advertising network, data broker, or analytics partner receives any of it.

Online play, account sign-in, and the leaderboard run on Base44, a platform operated by Wix, which hosts the app and stores its data on our behalf under a data processing agreement. Base44 acts on our instructions and is not permitted to use your data for its own purposes. Other players see only what the leaderboard shows.

We will disclose data where a law, court order, or lawful government request requires it, or where we need to investigate cheating, fraud, or abuse. If the company is acquired or merges, the data transfers with it and this policy continues to apply.

Deleting your account

You can delete your account from inside the app, through the Delete Account option in the Account menu. Deletion removes your account, your email address, your display name, and your game history, and your entries disappear from the leaderboard.

You can also request deletion through the account deletion form on our Privacy page. We complete requests within 30 days.

Deleted data persists in encrypted backups for up to 30 days, after which those backups expire and the data is gone. Aggregate statistics that no longer identify you, and any records we must keep to prevent abuse, may remain after deletion.

How long we keep data

We keep your account data for as long as the account exists. Crash reports are retained for 90 days. An account that is created but never used to play a game is removed after 90 days. An account that has been used is removed after one year with no sign-in, along with its game history and leaderboard entries.

Security

Traffic between the app and the servers uses HTTPS with TLS, and data at rest is encrypted with AES-256. Sign-in is handled by our hosting platform's authentication system, so passwords are never stored in the app's own data and are not visible to us. Access to production data is limited to named staff and requires multi-factor authentication. Our hosting platform holds SOC 2 Type II and ISO 27001 certification. No system is perfectly secure and we cannot guarantee absolute security.

Children

Checkers requires an account and publishes a display name on a public leaderboard, so the app is not directed to children under 13, and we do not knowingly collect personal information from a child under 13. A parent or guardian who believes their child has created an account can write to us at the address below or use the deletion form, and we will remove the account.

Your rights

You can access, correct, or delete your data using the in-app controls or the deletion form. Residents of California, Virginia, Colorado, Connecticut, and other states with comprehensive privacy laws have rights of access, deletion, correction, and opt-out of sale or targeted advertising. We do not sell personal information and do not share it for cross-context behavioral advertising.

Residents of the European Economic Area and the United Kingdom have rights of access, rectification, erasure, restriction, portability, and objection under the GDPR, and may lodge a complaint with their local supervisory authority.

International transfers

Data is processed and stored in the United States. If you play from outside the United States, your information is transferred there. Where personal data moves out of the European Economic Area or the United Kingdom, we rely on the European Commission's standard contractual clauses.

Changes

We will revise this page and update the date above before any change takes effect, and will notify you in the app if the change materially expands what we collect.
