Privacy Policy

Last Updated: May 15, 2026

1. No Data Collection

At Calcova, we believe your mathematical work is your own. **We do not collect, store, or transmit any of your personal data, calculation history, or expressions to our servers.** Your privacy is built into the core of our application.

2. Local Storage Only

All data generated while using Calcova—including your calculation history, formula library, and custom settings—is **stored exclusively on your local device**. We do not have access to this information, and it never leaves your device unless you choose to back it up via your own private cloud services (like iCloud).

3. Subscriptions and Payments

Payments for Calcova Pro are handled entirely through **Apple StoreKit**. We receive confirmation of your subscription status to unlock premium features, but we do not collect or store your name, email, credit card information, or billing address.

4. Third-Party Services

Calcova does not use third-party analytics, tracking pixels, or advertising networks. We do not sell your data because we do not have any data to sell.

5. Data Security

Because your data stays on your device, its security is managed by your device's operating system. We recommend using standard security features like FaceID, TouchID, or a passcode to protect your device and your Calcova data.

6. Contact Us

If you have any questions about our commitment to your privacy, please reach out to us at hongphat.ly@saposs.com.
