Big Talk Calc ("the app") is developed by Aleksandr Pakhomov. This policy explains how the app handles your information.
Summary
Big Talk Calc does not collect, store on our servers, share or sell any personal information.
Information we do not collect
We do not collect your name, email address, location, contacts, photos, device identifiers or any other personal data. The app has no accounts, no advertising, and no analytics or tracking tools.
Information stored on your device
The app saves a few settings on your device only, so it works the way you left it. These are your speech preferences (speaking on or off, speed and language) and a daily count of free calculations. This information never leaves your device and is not accessible to us. It is deleted when you delete the app.
Your calculations
Numbers and calculations you enter stay on your device. They are not sent anywhere.
Speech
The app uses your device's built-in text-to-speech voices to read buttons and results aloud. Speech is generated on your device.
In-app purchases
The app offers an optional one-time purchase (Pro). Payments are processed entirely by Apple through the App Store. We do not receive or store your payment details, name or Apple Account information. We only receive confirmation from Apple, through the device, that the purchase has been made.
Third parties
The app does not use any third-party services, software development kits or advertising networks. Apple's App Store handles purchases under Apple's own privacy policy.
Children's privacy
Because we do not collect any personal information, the app is safe for users of all ages.
Changes to this policy
If this policy changes, we will update the date at the top. Continued use of the app after a change means you accept the updated policy.
