Privacy Policy

1. Data We Collect

Data stored locally on your device:

• Lookup history: DNS lookup results including domain names, record types, and timestamps are stored in a local database on your device.
• Preferences: App settings are stored in SharedPreferences.

Data we do NOT collect:

• We do not collect or transmit your DNS queries, results, or browsing history to any server.
• We do not track your usage or activity.
• We do not have analytics or telemetry.
• We do not collect your IP address, device identifiers, or location.

2. Network Requests

DNSLens makes the following network requests as part of its core functionality:

• DNS queries: UDP/TCP queries to public DNS resolvers (Google 8.8.8.8, Cloudflare 1.1.1.1, Quad9 9.9.9.9, OpenDNS 208.67.222.222) for the domains you look up.
• Propagation checks: Queries to multiple resolvers simultaneously to compare results.

All of these requests are initiated by you and are not automated or background processes.

3. Third-Party Services

Google AdMob

The App displays advertisements via Google AdMob. Google may collect device identifiers, IP addresses, and usage data for ad targeting and measurement. This is governed by Google's Privacy Policy.

4. Data Security

• All lookup data is stored locally in an on-device Room database.
• The app database cannot be extracted via Android backup (backup is disabled).
• Domain input validation prevents injection attacks.
• DNS queries are sent only to trusted public resolvers.

5. Data Retention

All data is stored locally on your device. You can clear lookup history at any time within the app. Uninstalling the App deletes all stored data.

6. Children's Privacy

The App is not directed at children under 13. We do not knowingly collect information from children.

7. Changes to This Policy

We may update this Privacy Policy from time to time. The updated version will be accessible within the App and at this URL.
