Software that respects you
Three different problems, one set of rules about how they are built.
Your data stays with you
No accounts, no cloud of ours, no tracking. Where an app syncs, it syncs to your own Google Drive — a file you can open, move or delete without asking us.
They work with no internet
Not degraded offline — designed for it. On a flight, in a shop with a dead connection, at a retreat: the app does not notice.
You pay once, or once a year
No ads, no data sold, no subscription that quietly becomes indispensable. The free tiers have no time limit on them.
