Privacy Policy

Last updated: April 18, 2026

Quan105Labs ("we", "our", "us") operates the Quan105Labs website and the mobile applications published under the Quan105Labs developer account on Google Play (the "Services"). This page informs you of our policies regarding the collection, use, and disclosure of personal information when you use our Services.

1. Information we collect

We design our apps to collect as little information as possible. Depending on the specific app, we may collect:

  • App usage data — anonymous statistics such as app opens, session duration, and feature usage, to help us improve our apps.
  • Crash reports — technical information automatically generated when the app crashes, including device model, OS version, and stack traces. This data is anonymous and cannot be used to identify you.
  • Device information — basic technical information such as Android version, screen size, and language settings, used only to deliver a suitable experience.

We do not collect your name, email address, phone number, contacts, location, photos, or any personally identifiable information unless you voluntarily provide it (for example, by emailing us for support).

2. How we use information

The limited information we collect is used solely to:

  • Improve app stability and fix bugs
  • Understand which features are used and which need improvement
  • Provide customer support when you contact us
  • Comply with legal obligations

3. Third-party services

Some of our apps may use the following third-party services. Each service has its own privacy policy:

  • Google Play Services — required for app distribution. Google Privacy Policy
  • Firebase (Google) — for crash reporting and anonymous analytics. Firebase Privacy
  • Google AdMob — if an app displays ads, AdMob may serve personalized or non-personalized ads. AdMob Privacy

4. Data retention

Anonymous analytics and crash data are retained by the respective third-party services according to their policies. We do not store any personal data on our own servers.

5. Children's privacy

Our Services are not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us so we can delete it.

6. Your rights

You have the right to:

  • Request information about what data is collected about you
  • Request deletion of any data we may hold
  • Opt out of personalized ads via your Android device settings
  • Uninstall our apps at any time

To exercise these rights, email us at quan105labs@gmail.com.

7. Changes to this policy

We may update this Privacy Policy occasionally. Changes will be posted on this page with an updated "Last updated" date. Material changes will be announced through our apps or website.
