We do not connect to your bank
It is the most common question and at the same time the most important product decision. Below is the full reasoning and exactly what we store.
Why having no integration is an advantage
Recurring payments by definition do not change — rent is the same every month, so is a subscription. Counting them needs no transaction feed; a list you fill in once is enough. A bank integration would solve a problem that is not here, and introduce four new ones.
Purchases, locations, payee names — none of it reaches us, because we have no way of seeing it.
PSD2 access expires. Apps built on it keep asking you to log into your bank again.
A big bank, a credit union, a company card, a payment from a parent, cash for rent — you enter all of it the same way.
The worst case is a list of service names and amounts. Unpleasant, but it opens nobody a path to your money.
- Service names and categories
- Amounts, cycles and charge dates
- Asset valuations you enter yourself
- Email address and password hash
- Receipt photos you attach to warranties, stored privately
- Account or card numbers
- Bank logins or passwords
- Transaction history or bank balances
- Anything from your mailbox
How it is protected
The database and files live in Frankfurt, in a data center certified to ISO 27001. Website hosting and email sending are run by US companies, under the EU standard contractual clauses.
TLS 1.3 in transit, AES-256 on disk and in backups.
Argon2id hash with salt. The password cannot be recovered from it — not by us either. You can also turn on two-step sign-in: a code from an app on your phone on top of the password.
Daily, kept 30 days, encrypted with a separate key.
We reach into account data only at your explicit request in a ticket, and it is logged.
Subscription only. We do not sell data and have no advertisers.
Other questions
Yes, both in your account in the panel (Account → Data and privacy), without contacting us. The export is a JSON file with the full history, including price changes. Deletion removes data irreversibly within 24 hours; backups expire after 30 days.
We commit to 90 days notice and to keeping export working until the last day. The JSON format is documented, so the data can be loaded elsewhere — you are not left with nothing.
Only when you ask for it. Suggestions in “Save money” come from stated rules computed on your account, and Ask answers prepared questions from your own data inside the app — neither uses a language model. The one exception is the “Check with AI” button in “Save money”: when you press it, the server sends your active items (names, plans, categories, amounts, billing periods, usage, plan limits, renewal dates and what you tick under “More options” — without names or your card) to Claude, Anthropic's model, and shows its suggestions. Your email address, notes and income are not sent, and Anthropic does not use data sent through its API to train models.
