We can see your accounts. We can't touch them.

Enforced byPlaid, read-only scope

Your bank password never reaches us

Plaid runs the login in its own window. We receive a token you can revoke from Settings, from Plaid, or from your bank.

Plaid

Encrypted at rest and in transit

AES-256 on disk, TLS on the wire. The database sits on Supabase inside AWS, and Cloudflare terminates every connection.

Isolated per household

Row-level security scopes every query to your household inside the database itself, on every table, not only in app code.

Supabase

Hosts you can look up

Supabase is SOC 2 Type II audited and runs on AWS. Vercel serves the app. Promi itself has not been audited yet, and this page will say so until it has.

We never see your card number

Stripe handles billing on the web and Android, Apple on iOS. Card details go to them and never to our servers.

Never sold, never trained on

No ads, no affiliate links, no third-party trackers. AI insights run on Anthropic under an agreement that keeps your data out of model training.
