Privacy
Last updated: 2026-06-30
Your privacy matters. This template policy describes how a zmlkit-based application handles personal data — adapt it to your business and jurisdiction.
1. Who we are
[Company Name] ("we", "us") operates the application and website you are using. This Privacy Policy explains what personal data we collect, why, and the choices you have. For questions, contact us at [privacy@example.com].
2. Information we collect
Account data: email address, display name, and authentication identifiers (including OAuth provider IDs when you sign in with Google or GitHub).
Usage and content: prompts and generations you create, credit transactions, and support messages.
Payment data: orders and subscription status. Card details are handled by our payment processors (e.g. Stripe, RevenueCat) and are not stored on our servers.
Technical data: IP address, device information, and diagnostics used for security, fraud prevention, and reliability (including crash/error monitoring).
3. How we use your data
To provide and secure the service: authentication, credits and billing, AI features, and abuse prevention.
To communicate with you about your account, transactions, and important changes.
To comply with legal obligations and enforce our terms.
We do not sell your personal data.
4. Legal bases
Where applicable (e.g. GDPR), we process data to perform our contract with you, for our legitimate interests in operating and securing the service, to comply with the law, and with your consent where required.
5. Sharing and processors
We share data with service providers that help us run the product, such as hosting, database, object storage, email, payment, AI inference, and error-monitoring providers. Each app is isolated; your data is scoped to the app you used.
We may disclose data if required by law or to protect rights, safety, and the integrity of the service.
6. Third-party SDKs
Depending on which features are enabled in the build you use, the app and website embed the following third-party SDKs, which may collect the data listed below. [Template note: keep this list in sync with the SDKs your app actually enables and delete the rest — China app-store review compares it against the binary.]

The service is not directed to children under the age required by your jurisdiction, and we do not knowingly collect their data.
11. Changes to this policy
We may update this policy from time to time. Material changes will be notified through the service or by email. Continued use after changes means you accept the updated policy.
