Numink Privacy Policy
How the Numink Android app handles your information. In short: it collects none. Your notebooks stay on your phone, and the only network use is Google Play processing the optional Pro purchase.
Who this covers
This policy covers Numink, the notebook calculator for Android developed by Ahmedonics Technologies (Private) Limited. It was first published on 29 May 2026; this version is dated 18 October 2026. How this website handles its visitors is described in the company privacy policy.
Information we collect
None. Numink does not collect or transmit your notebooks, calculations or any personal data. The app has no servers of its own, no analytics and no advertising.
Information stored on your device
Your notebooks, saved variables, pinned results, templates and settings are stored on your device only. Uninstalling the app removes them. A backup file you create is written only to the location you choose and stays under your control.
Permissions
Numink requests no location, contacts, camera or microphone permission. It holds the Internet permission only so that Google Play Billing can process the optional Pro purchase; it is not used to send your data anywhere. Saving a backup or a QR image goes through the system file picker or share sheet, which you control.
Purchases
The optional Pro purchase is processed by Google Play Billing. Numink does not receive or store your payment details. Google's handling of purchases is governed by the Google Play Terms of Service and Google's Privacy Policy.
Children
Numink is a general-audience utility and does not knowingly collect data from anyone, including children under 13.
Third-party software
The app includes open-source libraries: ZXing, AndroidX and Jetpack Compose, and the Kotlin standard library, all under the Apache License 2.0. They run on the device and do not collect data.
