What we keep

If you use the calculators without an account, nothing you type leaves your device except when you make a share card, which stores only the numbers shown on the card. Recent sums are kept in your browser's local storage.

With an account we keep your email address, a hashed password (held by our sign-in service), and the items, trips and settings you enter. If you subscribe, Stripe handles your card; we keep only Stripe's customer and subscription references.

What we use it for

To run your ledger, to send the monthly profit email (you can turn it off from any email or from Settings), and to send account notices. We don't sell your data, and we don't share it except with the services that run Hustl: our hosting and database (Helm7), payments (Stripe), email (ThreadCamp), and Google Analytics for anonymous usage numbers.

Analytics

We measure which pages and steps people use with Google Analytics. Signed-in usage is tagged with a one-way hash of your account id, never your email.

Your choices

Download everything from Settings as a CSV at any time. Delete your account from Settings and your items, trips and share cards are deleted with it. Questions: [email protected].
