Montavelo started as a personal private numbers kept in a notebook. The notebook worked because it asked nothing: no accounts to impress, no streaks to mourn. The app keeps exactly that spirit and adds the two things paper cannot do — a weekly review that notices drift, and exports that keep your history yours.
Today the private numbers ships with a weekly review, plain exports and a shared mode for households. Nothing else is planned this year — depth beats feature count.
The tone is plain-spoken, steady. If that sounds like your kind of tool, the first week takes one evening.
Manual entries first; connections optional, encryption standard.
If a chart needs a legend to explain itself, it does not ship.
Every byte you put in can come back out as CSV.
We measure weeks kept, not minutes spent.
