Privacy Policy

We keep data collection to what the Service needs to work.

• Account information. If you choose to sign in (for example with Google), we receive your name, email address, and profile image from the sign-in provider so we can create and identify your account.
• Gameplay data. Daily challenge results, streaks, calorie estimates, break schedules, and settings you configure, so your progress can be shown back to you and, if you are signed in, synced across devices.
• Guest data. If you do not sign in, gameplay progress and preferences are stored locally in your browser and are never sent to our servers.
• Camera input (movement games only). Movement games use your device camera for on-device pose detection. Video frames are processed locally in your browser to detect movement; they are never uploaded, transmitted, or stored by us. Camera access is only requested when you open a movement game, and you can decline or revoke it at any time in your browser settings.
• Usage and device data. Basic technical information such as browser type, extension version, and coarse usage metrics (for example, which games are played), used to fix bugs and understand which features are useful.
• Billing information. If you subscribe to a paid plan, payment is handled by our payment processor. We receive confirmation of your subscription and its status, but we do not store your full card or bank details.

• To operate the Service — showing your board, streaks, and history.
• To sync your progress across devices when you are signed in.
• To provide, manage, and bill paid subscriptions.
• To respond to support requests you send us.
• To understand aggregate usage and improve the Service.
• To keep the Service secure and prevent abuse.

We do not sell your personal information, and we do not use camera video for advertising or profiling.

Signed-in account and gameplay data is stored with our infrastructure providers. Guest progress and local preferences stay on your device using your browser's local storage and are not transmitted to us. Camera frames for movement games are processed entirely on-device and are never stored anywhere.

We do not sell personal information. We share limited data only with:

• Service providers who host our infrastructure, process payments, or provide analytics, bound by confidentiality obligations.
• Sign-in providers (such as Google), which handle your authentication.
• Authorities, if required by law or to protect the rights, safety, or property of our users or the public.

• Play as a guest at any time to avoid creating an account.
• Skip camera games entirely and use keyboard-based games instead.
• Revoke camera permission at any time in your browser settings.
• Access, correct, export, or delete your account data by contacting us — see our Data Deletion Policy for details.
• Cancel a paid subscription at any time — see our Refund & Cancellation policy for details.

We retain account and gameplay data for as long as your account is active, so your streaks and history remain available to you. If you delete your account, we remove your personal data within a reasonable period as described in our Data Deletion Policy, except where retention is required for legal, tax, or fraud-prevention purposes.

The Service is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will remove it.

We use reasonable technical and organizational measures to protect your information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above, and we'll take reasonable steps to notify active users of significant changes.

Questions about this policy or your data can be sent to support@thegoodgametheory.com.
