Privacy
MultiCalc collects nothing and sends nothing.
Last updated: 5 September 2026
There is no account, no server, no analytics, no crash reporting and no advertising. The app never asks you to sign in.
On Android it is not granted the INTERNET permission at all, so
it could not send anything anywhere even if it tried to.
What is stored, and where
Everything you do in MultiCalc is written to the app's own private storage on your phone, which nothing except the app can read:
- the calculators you have open, their names and their colours
- what is currently on each display
- each calculator's history of past calculations
- your theme and vibration settings
Android removes all of it when you uninstall the app. You can clear it sooner from your phone's Settings, under Apps, MultiCalc, Storage.
What leaves your phone
Nothing, unless you choose to send it.
- Export history. When you tap Export, the app hands a file to Android's own save dialog and you choose where it goes. Where it lands after that is up to you, and the app has no further part in it.
- Support link. Tapping "Support this project" opens a page in your browser. That page is served by GitHub and is covered by GitHub's privacy statement. MultiCalc sends nothing with the link about you or your use of the app.
Permissions
One: VIBRATE, so keys can give a short buzz. You can turn it off in
the app's Settings.
The app also declares in its manifest that it needs to see which app on your phone is a calculator. That is how Android's package visibility works, and without it the app cannot find your calculator to open a second copy of it. It is a declaration about what the app may look up, not a permission you grant, and nothing about the apps on your phone is recorded or transmitted.
MultiCalc does not ask for internet access, location, contacts, camera, microphone, files, or anything else.
Children
MultiCalc is a calculator. There is no advertising, nothing to buy, no user generated content, no social features and no data collection, so there is nothing in it that treats children differently from anyone else.
Changes
If this policy ever changes, the new version replaces this page and the date at the top changes with it.
