The spreadsheet
The workbook runs on your computer or Google Drive. We do not receive the figures you type. There is no account, no upload, and no telemetry in the file.
The future app
Designed local-first: books stay on the device. Optional encrypted backup you control. We do not host your income, expenses, or tenant details. If optional cloud sync is ever added it will be UK/EU servers, encrypted, export + delete, no selling data, no training models on your books, and ICO registration if we become a data controller.
This waitlist
If you email us, we receive only what you send — typically your name and email — so we can tell you when the app (or an update) is ready. We do not collect financial data through this page. You can ask to be removed by emailing the same address.
