Privacy Policy

Effective Date: 2025-06-29

This Privacy Policy describes how “Qimen.Guru” (“we,” “us,” or “our”) handles information in connection with your use of the “Qimen.Guru Qimen Calculator” mobile application (the “App”). Your privacy is important to us, and we are committed to protecting it.

1. Data Collection and Use

Our App is a Trusted Web Activity (TWA) that displays our web application within a native Android application frame.

We collect minimal non-personal data to facilitate secure access to certain features of our backend services. When you first interact with parts of the App that require special access, the App:

• Signs you in anonymously
• Stores an authentication token (cookie) to manage your session

This process does not collect personally identifiable information. The cookie is used only to validate your session when accessing protected API routes.

Additionally, the App may store certain user preferences or application settings in your device’s local storage, including:

• Your selected location (manually specified or device-detected, if you grant location permission)
• App interface preferences or configuration settings

2. Location Data

If you choose to grant location access, we use this information solely to power the in-app features that require it.

Your location is not tracked in the background, nor is it stored remotely, shared or used for any purpose other than providing direct, immediate functionality within the app. You can revoke location permissions at any time through your device’s system settings.

3. Data Sharing

We do not share any personally identifiable information with third parties.

4. Data Security

We rely on the built-in security measures of the Android operating system and the browser engine to protect the information stored locally on your device. Since we do not transmit or store your data on external servers, the risk of a remote data breach is eliminated.

5. Third-Party Services

The App uses the following third-party services:

• Cloudflare Web Analytics: We use Cloudflare’s privacy-first analytics to collect aggregate, non-personal data such as page views and browser types. This data helps us understand general usage patterns and improve the App. Cloudflare Web Analytics does not use cookies or track individual users across sites.

6. Your Choices

You may:

• Clear app local storage data via your browser or app settings
• Revoke location access at any time

7. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected with an updated effective date. Continued use of the App after any changes constitutes acceptance of the revised policy.

8. Contact

If you have any questions or concerns regarding this Privacy Policy, you may contact us at: https://qimen.guru

By using this App, you agree to the terms outlined in this Privacy Policy.
