About CapKin

Why CapKin exists

CapKin started from a simple frustration: in most homes the budgeting falls to one person, and the spreadsheet quietly dies by February. We're building the budget you can keep up with by just talking — say what you spent, confirm it in a tap, and the whole household stays on the same page.

We keep a person in the loop on every entry, and every total is recomputed on the server, so the shared picture always adds up. We track only what you tell us — we never touch your bank or move your money. We're building in the open, with our founding households shaping what comes next.

The principles we build by

• —A person in the loop. Every entry is confirmed by a person, and children's entries wait for a parent's approval.
• —Your bank stays yours. No bank connection, no credentials, and no money movement — ever.
• —One shared picture. The whole household logs to the same budget, and every total is recomputed on the server.
• —Calm by default. No dark patterns and no newsletter pop-ups. CapKin is built to WCAG 2.1 AA.
• —Kids included, safely. Children can log their own spending for a parent to approve, with no debit card and no ads.
