Private, like Quilleaf itself
- Nothing you type leaves your browser. The sums are done on your device. There is no sign-up, no cookies of ours, no analytics and no ads.
- A link keeps your figures. Each calculator puts them after the # sign in the address bar, so you can bookmark or share them. Browsers never send that part to a server, so quilleaf.com doesn’t see it.
- The maths is shown. Every calculator explains its formula and what it assumes, and its tests check the answers against known values.
Quilleaf is a free app for Android that keeps your money ledger on your phone, with no sign-up. It reads your bank SMS to fill itself in, and tracks your loans, cards, bills and investments.
These figures are estimates to help you plan, not financial advice. Banks, lenders and fund houses round and time things their own way, and rates change: check with them before you decide.
