Privacy Policy
Last updated July 7, 2026
This policy explains what information Mahjee collects, how we use it, and the choices you have. We keep it short and plain because that's how a privacy policy should be.
This Privacy Policy applies to the Mahjee website at mahjee.app and, when it launches, the Mahjee mobile app (together, the “Service”), operated by Mahjee (legal entity name) (“we,” “us,” “our”).
Information we collect
Today, the Service is a simple marketing site. It has no sign-up form and doesn't ask you for your name, email, or any other personal details. We collect only:
- Basic usage data. Like most websites, our hosting and privacy-friendly analytics may record standard technical information such as your approximate region, browser type, and the pages you view. We use this in aggregate to understand interest and improve the site.
When the app launches, we expect to also handle: an account email (if you choose to create an account), your practice progress and mastery data (stored primarily on your device and synced to our servers so you don't lose it), and standard diagnostics. We'll update this policy with the specifics before those features ship.
What we do not collect
We do not sell your personal information. We don't collect payment details on this site. We don't ask for more than we need.
How we use information
- To operate, secure, and improve the Service.
- To respond when you contact us.
- To comply with legal obligations.
How we share information
We share information only with service providers who help us run the Service — for example, our website host and analytics provider — and only as needed for them to perform that work. We may also disclose information if required by law or to protect our rights. We never sell your data.
Data retention
We keep the limited usage data described above only as long as needed for the purposes above, and no longer.
Your choices and rights
- Access, correction, deletion. Depending on where you live (for example, under the GDPR or California's CCPA/CPRA), you may have the right to access, correct, delete, or port your personal information, and to object to certain processing. To exercise any of these, contact us below.
Children
The Service is not directed to children under 13, and we do not knowingly collect personal information from them.
International visitors
We operate from your country/region. If you access the Service from elsewhere, your information may be processed in a country with different data protection laws than your own.
Security
We use reasonable technical and organizational measures to protect your information. No method of transmission or storage is perfectly secure, so we can't guarantee absolute security.
Changes to this policy
We may update this policy as the Service evolves — especially when the app launches. We'll change the “last updated” date above and, for material changes, provide a more prominent notice.
