Privacy Policy
Last updated: 12 June 2026
Hanzi Master (“we”, “us”, “our”) respects your privacy. This policy explains, in plain language, what information we collect and how we use it when you use our website at hanzimaster.app and our mobile apps (together, the “Service”).
Information we collect
- Account information. If you create an account, your email address and a password. Passwords are always kept in encrypted form, we never see them.
- Learning progress. The characters you’ve studied, your review schedule and your streak, so we can save your progress and sync it across your devices.
- Basic technical data. Standard information such as device or browser type and general usage, collected automatically to keep the Service secure and working reliably.
We do not show ads, and we do not sell or rent your personal information to anyone.
How we use your information
- To run the Service, sign you in, and save and sync your progress.
- To send essential account emails, such as sign-up confirmation and password resets.
- To show optional study reminders, which are scheduled on your own device.
- To keep the Service secure and to improve it.
How your information is stored
Your account and progress are stored securely with trusted third-party providers that help us run the Service, protected by encryption in transit and standard access controls. Some settings and progress are also saved locally on your device. We keep your data only for as long as your account is active.
Your choices and rights
You can access, update or delete your personal information at any time. Depending on where you live (for example under the EU/UK GDPR or California’s CCPA), you may have additional rights over your data. To make any request, just email us, see “Contact” below.
Deleting your account
You can delete your account and its associated data at any time by emailing us at privacy@hanzimaster.app. Once deleted, your personal data is removed, except anything we’re legally required to keep.
Purchases & subscriptions
If you buy a subscription or a one-time upgrade, your payment is processed by the relevant app store (Apple or Google) or by our payment provider (Stripe), we never receive or store your full card details. We keep a record of what you purchased and your subscription status so we can unlock your access and keep it in sync across your devices.
Children
The Service isn’t directed at children under 13, and we don’t knowingly collect their personal information. If you believe a child has provided us information, contact us and we’ll delete it.
Changes to this policy
If we update this policy, we’ll post the new version on this page and update the “Last updated” date above.
