Interpolation Calculator ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle user data, how advertisements are displayed in the App, and how users can opt to remove ads.

1. No Data Collection

We respect your privacy and do not collect, store, or share any personal data from users.

We do not:

• Collect personal information such as names, email addresses, phone numbers, or locations.
• Track user activity within the App.
• Use cookies or tracking technologies for data collection.
• Sell or share any information with third parties.

Since the App does not collect data, there is no risk of unauthorized access, data breaches, or misuse of personal information.

2. Advertising and In-App Purchases

The Interpolation Calculator App contains advertisements to support its free availability. Additionally, users have the option to remove ads through an in-app purchase.

2.1. Advertisements

• The App displays third-party advertisements, which may be served by Google AdMob or similar ad networks.
• Ad providers may use non-personalized advertising (based on general device information, such as app usage) to serve relevant ads.
• Ads are displayed within the App interface but do not interfere with core functionality.

2.2. Removing Ads

• Users can remove ads permanently by purchasing the "Remove Ads" feature available in the App.
• Once the purchase is completed, advertisements will no longer be displayed within the App.
• The purchase is tied to the user's Google Play account and can be restored if the App is reinstalled on the same account.

2.3. Third-Party Ad Services

• Since ads are provided by third-party networks, they may collect anonymous data to improve ad relevance.
• Any data collection by ad networks is subject to their respective Privacy Policies.
• Users are encouraged to review Google AdMob's Privacy Policy (or the applicable ad network) for more details on their data practices.

3. Third-Party Services

Other than ad services, the App does not integrate with third-party platforms, cloud storage, or analytics tools.

If advertisements are displayed, they are managed by third-party providers, and we do not control their data collection policies.

4. Data Protection and Security

Since the App does not collect user data, there is no need for additional security measures on our side. However, we recommend users:

• Review the privacy settings of their Google Play account.
• Check privacy policies of advertising providers if they are concerned about targeted ads.
• Keep their devices updated for security enhancements.

5. User Rights and Control

Users have full control over their experience within the App.

• Opting Out of Ads – Users can remove ads through the in-app purchase.
• Managing Ad Preferences – Users can modify their ad settings in Google Play or disable personalized ads through device settings.
• No Data Requests – Since we do not store user data, we do not process access, modification, or deletion requests.

6. Children's Privacy

The App is not specifically designed for children, and advertisements displayed may not always be child-friendly.

Parents can:

• Disable ads through an in-app purchase.
• Use parental controls in Google Play to limit app access or ad content.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected within the App or on our website.

The "Last Updated" date at the top of this document will indicate the most recent revision. Continued use of the App after updates means acceptance of the revised policy.
