Arithmix Privacy Policy
Last updated: October 14, 2026
The short version: Arithmix does not collect, store, or share your personal information. There are no accounts, no ads, and no tracking. Your practice progress and settings stay on your device.
Who we are
Arithmix is a mental math practice app published by KN Byte Labs and built by Nadia Iskandar and Kristian Iskandar. In this policy, "we," "us," and "our" mean KN Byte Labs.
Information we collect
We do not collect any personal information through Arithmix. Specifically, the app does not:
- require you to create an account or sign in
- ask for your name, email address, age, location, or contact information
- collect device identifiers or advertising identifiers
- use third-party analytics, advertising, or tracking tools
- access your contacts, photos, microphone, camera, or location
Data stored on your device
To work properly, Arithmix saves some information locally on your device, such as your selected level, your progress, your test results and speed, and any custom flashcards or tests you create. This information stays on your device. We cannot see it, and it is not sent to us or to anyone else. If you delete the app, this data is deleted with it.
Children's privacy
Arithmix is designed for students, including children under 13. Because we do not collect personal information from anyone, including children, there is no personal information to share, sell, or disclose. We do not show ads, and we do not include links or features that let children communicate with others or share information publicly.
Information from Apple
If you choose to share analytics or crash data with app developers in your device's settings, Apple may provide us with aggregated, anonymous information about app usage and crashes. We use this only to find and fix problems. Apple handles this data under its own privacy policy, and it does not identify you.
Third parties
Arithmix does not share data with third parties because it does not collect any data. The app does not contain third-party SDKs that collect information.
Data security
Because your data stays on your device, it is protected by your device's own security features, such as your passcode and iOS data protection.
Changes to this policy
If we change how Arithmix handles information, for example by adding accounts or syncing, we will update this policy and the "Last updated" date above before the change takes effect.
