Privacy Policy
BEFUN AI TECH. PTE. LTD. ("BEFUN AI TECH", "we", "us", or "our") respects your privacy and is committed to protecting the personal information you share with us. This Privacy Policy explains what information we collect when you use our website and mobile applications (including Calculator Plus — Math Solver), how we use it, and your choices.
1. Information We Collect
We aim to collect as little personal data as possible. We may process the following categories of information:
- Device and app data. Device model, operating system version, app version, language and region settings, anonymous device identifiers, and crash diagnostics. This data helps us keep the app stable.
- Usage data. Anonymous, aggregated information about how features are used (for example, which calculator functions are opened) so we can improve the product.
- Photos you submit. When you point the camera at an equation to use the photo math solver, the image is processed to recognize and solve the equation. We do not use these photos to identify you and do not retain them beyond what is needed to return a result.
- Support communications. If you contact us at [email protected], we keep your message and contact details to respond to your request.
2. How We Use Information

- To improve product quality and develop new features.
- To respond to questions and provide customer support.
- To comply with applicable laws and protect our legal rights.
3. Information We Do Not Collect
Calculator Plus does not require an account. We do not ask for your name, email address, phone number, or location to use the core features of the app. We do not sell personal information, and we do not use your data for behavioural advertising.
4. Sharing of Information
We do not sell or rent your personal information. We may share limited information only in the following circumstances:
- With service providers that help us operate the product (for example, crash reporting and analytics infrastructure). These providers are contractually required to handle data on our behalf and only for the purposes we instruct.
- If required by law, regulation, legal process, or governmental request.
- In connection with a merger, acquisition, or sale of assets, in which case we will provide notice and continue to protect your information.
