Privacy Policy

Phong Thủy Số Sim is an independent app that analyzes phone number numerology. This policy explains how we handle your information.

1. Information We Collect

Phong Thủy Số Sim does not require account registration and does not store personal information. Specifically:

• Last 4 digits of a phone number — entered by you for analysis. Only these 4 digits are sent to our server. We never store the full number or link it to your identity.
• Anonymous usage data — lookup type, selected language, ad view counts. No personally identifiable information.
• Ad data (Google AdMob) — AdMob may collect your device advertising ID and anonymized data to serve relevant ads. See Google's Privacy Policy.

2. How We Use Information

• Provide numerology analysis results based on the 4 digits you enter
• Improve app quality and performance
• Display ads to keep the app free

3. Sharing of Information

We do not sell or trade your information to third parties, except:

• Google AdMob — for ad delivery
• Cloudflare — server infrastructure and CDN

4. Local Storage

The app caches lookup results on your device (up to 7 days) to avoid unnecessary reloading. This data exists only on your device and is removed when you uninstall the app.

5. App Permissions

Phong Thủy Số Sim requests only the minimum permissions required:

• Internet — to fetch results and display ads

The app does not access your contacts, camera, location, or any other sensitive data.

6. Children

This app is not directed at children under the age of 13. We do not knowingly collect information from children.

7. Changes to This Policy

We may update this policy. Any changes will be posted on this page with a new "Last updated" date.
