Scientific Calqon ("the App") is developed and published by Pinclave ("we", "us", "our"). This policy explains how the App handles your information. The short version: we do not collect, transmit, or store your personal data on our servers — everything you enter stays on your device.
1. Information we collect
We collect nothing. No accounts, no sign-in, no analytics, no advertising, no tracking. The expressions you type, your results, calculation history, matrices, graphs, statistics data, and settings are stored only locally on your device and are never sent to us or any third party.
2. How your data is stored
Your calculation history and preferences (theme, angle mode, display settings) live in the App's local storage on your device. Nothing is synced, uploaded, or backed up to any server of ours. You can clear the history from within the App at any time.
3. Network use
The App is designed to work fully offline. The only network activity is subscription billing, which is handled entirely by the Apple App Store and Google Play. We do not receive or store your name, card details, or billing address.
Those platforms have their own privacy policies:
- Apple — https://www.apple.com/legal/privacy/
- Google — https://policies.google.com/privacy
4. Copying, sharing, and exports
Copying a result places it on your device's clipboard, and exporting a graph as an image or PDF hands off to your device's own share sheet. What happens after that — pasting into another app, saving to Files, sending it on — is governed by the privacy policies of the apps you choose, and we don't see that content.
5. Children's privacy
The App is suitable for students and general audiences, and it collects nothing from anyone.
6. Your choices and rights
We hold none of your data. You can clear your calculation history inside the App, and you can remove everything by clearing the App's data or uninstalling it — this is permanent and cannot be undone, and because we keep no copy, there is nothing for us to recover.
7. Changes to this policy
We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.
