Last updated 24 August 2026

The short version

This app collects nothing. There is no account, no sign-in, no analytics, no advertising, and no tracking of any kind. Nothing you enter leaves your phone.

Why that is a guarantee rather than a promise

The released app does not request the Android INTERNET permission. Without it, Android will not let the app open a network connection at all — so it cannot send your data anywhere even if it were asked to. The app also contains no networking code and no third-party analytics, advertising or crash-reporting libraries.

What the app stores, and where

Everything the app remembers is written to private storage on your own device, readable only by this app:

Home-screen widgets read that same local data in order to draw. It is never transmitted.

Deleting your data

Removing a place from the app deletes it. Uninstalling the app deletes everything the app has stored, including anything its widgets were using. There is nothing held anywhere else, so there is nothing for us to delete on your behalf and no request for us to action.

Permissions

The app requests no runtime permissions — no location, no contacts, no notifications. A few normal, install-time permissions come from the Android libraries that draw home-screen widgets (ACCESS_NETWORK_STATE, FOREGROUND_SERVICE, RECEIVE_BOOT_COMPLETED, WAKE_LOCK). They are not used to collect anything, and without the internet permission they cannot be.

Sharing a time

When you share a proposed meeting time, the app hands the text and image to Android's own share sheet and you choose where it goes. It goes only to the app you pick. Nothing is copied to us.

Children

The app collects no personal information from anyone, of any age.

Time zone data

Time zone and daylight-saving rules come from the IANA Time Zone Database and are bundled inside the app. No lookup is performed over a network.

Changes to this policy

If this policy changes, the revised version will be posted at this address with a new date above. Material changes will also be described in the app's release notes on Google Play.
