Mum and dad’s bank

The guide

Mum and dad’s bank (Banque de papa et maman) is a virtual piggy bank you run for your child. Pocket money can go “to the bank”, the bank (you) pays generous interest to learn from, and your child watches the money grow on a page of their own.

▶ The 90-second video: why it helps with compound interest, how to deploy it, what parents do and what kids see (French and English subtitles).

About languages. The app is French first. The screens you see before your bank exists (welcome page, invitation, creating the bank, recovery card) are always in French; this guide gives each French button with its translation. Once your bank exists, switch it to English in Réglages → Langue → English: your parent space and your children’s pages change, whatever their phones are set to.

Who does what

The hostInstalled the app on their Cloudflare account and creates invitations from the /admin page. They cannot read any bank: no names, no amounts, no notes.
The parentRuns the bank: Sunday coins, deposits, withdrawals, the interest rate. They need to stay liquid to pay their kids :). Also they have a secret parent link and 12 recovery words.
The childLooks at their bank account with their own link, on their phone or tablet. They cannot change anything.

The promise

No recovery is possible without your 12 words or a backup. That is the price of privacy: nobody, not even the host, can find your bank for you. Create the bank explains what to keep, and where.
