Privacy policy

Last changed 20 October 2026

In short: Frank, his notes and where he’s been stay on your household’s own devices. Frank has no accounts, no analytics and no advertising, and no Frank server sits in the middle.

The app

Your notes stay in the household. Frank’s notes, and the trail of where he’s been, are kept only on your household’s own devices, and travel only between them, over Iceblock, encrypted. Nobody outside the household, not even Frank’s developer, can read them.

It sends nothing to us. The app has no analytics, crash reports, advertising or tracking, and doesn’t check for updates by itself. It never contacts a server of ours.

Android™’s backups are off, so Frank’s notes and trail aren’t copied to Google Drive.

What the household shares. Frank belongs to the whole household, so every member’s devices keep his trail: each time he was passed on or found, each note, and which member’s device wrote each one. The app never shows where Frank is or who’s around, but the trail is there on each member’s devices.

What your devices tell others. Frank travels over Iceblock, so your devices share what Iceblock’s privacy policy describes to find and reach each other: with your own devices, with the household’s, with anyone on the same local network, and with your router.

The website

The website, frank.tricauda.com, keeps no logs, sets no cookies and stores nothing in your browser. Everything it does happens in your browser, and it loads nothing from anywhere else.

Invitations stay private. A Frank invitation has its details after the #, which browsers never send to a server. Opening one shows it to you, and to nobody else.

Downloads

Frank isn’t out yet. When he is, this says where he’s downloaded from, and what that records.

Changes

This policy changes when Frank changes what he records or shares, and the date at its top says when it last did.
