Mobile App by Kamxol
Fimbi
Fimbi is a personal expense and bill tracker built to be private by design. There are no accounts, no sign-up, no ads, and no in-app purchases. Your financial data never leaves your device unless you export it yourself.
Last updated: 27 July 2026
Your expenses, income, bills, budgets, loans, and settings (language, currency, theme, notification preferences) are stored in a local database on your device. We do not transmit, collect, or have any access to this data. Uninstalling the app deletes it. You may create backup files (JSON/CSV) at any time; those files are saved or shared only where you choose to put them.
The Loans feature lets you record money you have lent to or borrowed from someone. To do that you may type in that person’s name (required) and, optionally, their phone number and address.
We never read your address book — the app has no contacts permission and no contact picker, so anything about another person is there only because you typed it. Like everything else, it is stored solely in the local database on your device and is never transmitted to us or anyone else. It is included in any JSON backup or CSV export you choose to create, so please consider that before sharing an export file with someone.
These are used only at the moment you ask for them, and nothing is uploaded:
If you turn on App Lock, unlocking is handled entirely by your device’s own fingerprint, face, or PIN system. The app is only told whether authentication succeeded or failed. Your biometric data never leaves the secure hardware on your device, and the app never sees or stores it.
The app is free and every feature is included. There are no ads, no subscriptions, and no in-app purchases, so no advertising, analytics, or billing SDK is bundled and nothing is sent to a third party.
Bill and loan reminders are scheduled locally on your device. No notification data is sent to any server.
Fimbi is a general-audience app and is not directed at children under 13.
If we change this policy, we will update this page and the effective date above. Material changes will be noted in the app’s release notes.
