Privacy

Numio apps collect nothing. There is nothing to opt out of.

The apps

No data collected. Nothing you do in the apps is sent to me or anyone else.
No analytics or crash reporting. No tracking libraries of any kind.
No ads.
No accounts. There’s nothing to sign up for.
No internet permission. None of the apps can go online, so they work fully offline.
Your data stays on your phone. Calculator history, alarms, world clocks, words Ezhuthola learns, and pinned clips are stored only on your device. Uninstalling the app deletes them.

Each app page lists every Android permission the app asks for and why: Numio Calculator, Clock by Numio, Ezhuthola, Decibel by Numio.

No cookies, no analytics and no trackers.
Fonts and images are served from this site, not from Google or other third parties.
The site is hosted on GitHub Pages. Like any web host, GitHub may keep standard server logs, such as IP addresses, for security. See GitHub’s note on Pages data collection.
Download buttons take you to GitHub, which has its own privacy statement.

Messages to info@getnumio.org are used only to reply to you. I don’t add anyone to mailing lists.
