Engineering Mechanical Tools

Last updated: 24-01-2026

Engineering Mechanical Tools (“the App”) is a paid mobile application providing mechanical engineering calculations and reference tools. We are committed to ensuring that your privacy is protected.

1. No Data Collection

We do not collect, store, or share any personal, sensitive, or identifiable user data.

• No Accounts: No login, signup, or user profiles are required.
• No Personal Info: We do not collect names, emails, phone numbers, or contacts.
• No Tracking: We do not use analytics, cookies, or background tracking scripts.

2. Payments & Licensing

The App is a one-time paid application. All financial transactions are processed securely through the Google Play Store Billing System.

• We do not have access to your credit card details or bank information.
• We only receive confirmation of payment from Google to validate your app license.

3. Camera & AI Features

The App includes optional features that utilize your device's camera for mechanical part analysis.

• Camera Access: Used only with your explicit permission.
• Image Processing: Images are processed in real-time. They are not stored on your device gallery or our servers.
• AI Disclaimer: To provide analysis, the App may transmit image data to Google's Gemini AI services. This data is processed temporarily and is not used by us to identify you.

4. Third-Party Services

To provide core functionality, the App interacts with:

• Google Play Services: For license verification and app updates.
• Generative AI Services (Gemini): For on-demand analysis features.

These services may collect technical data as per their own Privacy Policies.

5. Data Security & Storage

Since the App operates locally and does not maintain a database of user information, your data remains entirely on your own device. There is no cloud synchronization or remote storage of your calculations.

6. Children’s Privacy

This App is intended for use by engineering professionals and students. It does not knowingly collect any information from children under the age of 13.

7. Changes to This Policy

We reserve the right to update this policy to reflect changes in our App or legal requirements. Any updates will be posted on this page and reflected in the "Last Updated" date.
