Privacy Policy

Last Updated: October 26, 2023

Welcome to A-Ring Calculator Pro ("the App"). We are committed to protecting your privacy and providing a secure, professional experience. This Privacy Policy explains how we handle information within the Pro version of our application.

1. Information Collection and Use

A-Ring Calculator Pro is designed with a "Privacy First" philosophy. We do not collect, store, or transmit any personal identification information or sensitive user data to external servers.

• Personal Data: We do not require you to provide any personal information (such as name, email, or phone number) to use the calculator.
• Calculation Data: All calculations, history, and memory values are processed and stored locally on your device. This data never leaves your device.
• Usage Data: We do not track your app usage patterns or feature interactions.

2. Permissions and Their Purpose

The App requests minimal permissions necessary for core functionality and maintenance:

• INTERNET: Required for checking application updates via the Google Play Store and processing donation transactions.
• BILLING: Required to facilitate optional user donations via the secure Google Play Billing system.
• VIBRATE: Used solely to provide haptic feedback during button interactions (can be disabled in settings).

3. Third-Party Services

While the App itself does not collect data, it utilizes trusted third-party services provided by Google for platform-level functionality:

• Google Play Services: Used for app distribution and core system features.
• Google Play Billing: Handles secure transactions if you choose to support the developer via donations.

These services may collect certain information as governed by their own privacy policies. We encourage you to review Google's Privacy Policy.

4. No Advertising and No Tracking

Unlike the standard version, A-Ring Calculator Pro contains no advertisements. Consequently:

• There are no third-party advertising SDKs (such as AdMob or Unity Ads) included in this version.
• We do not collect or share your Advertising ID (AAID).
• There are no trackers or analytical cookies embedded in the application.

5. Data Security

We value your trust in using our App. Since your data is stored locally, its security depends on your device's security settings. We recommend using standard device security features (passcode/biometrics) to protect your local data.

6. Children’s Privacy

Our App does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children. If we discover that a child under 13 has provided us with personal information, we immediately delete this from our servers (though no such information is typically requested).

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page.
