Flousi

Privacy Policy

Last updated: August 23, 2026. This policy explains how Flousi handles data in the website, PWA, and mobile app.

Privacy-first design

Flousi is a personal finance tracking and decision-support app. It runs local-first: your accounts, transactions, assets, notes, imports, and settings are stored in your device or browser storage. In this release Flousi does not upload your finance records to our servers. Flousi never connects to your bank and never asks for a banking password.

Data you enter

Flousi may store the finance records you add, including account names, balances, transactions, categories, imported statement details, assets, liabilities, vehicle information, settings, app PIN settings, and notes. Flousi does not ask for bank login credentials and does not need your card PIN.

How Flousi uses data

Your data is used to calculate totals, charts, category breakdowns, account summaries, net worth, duplicate checks, and review-first insights. Flousi does not initiate bank transfers, card payments, loan payments, crypto orders, investment trades, or any other movement of money.

Local storage and your Flousi profile

Your finance records are stored in your browser or device storage. Online backup of those records is not enabled in this release, so they stay on the device you entered them on. Clearing your browser storage or losing the device loses the data, which is why the app offers an export.

You can create a Flousi profile to sign in. That profile holds only account details - your email address or username, a hashed password, and the date of birth used for the minimum-age check - not your finance records. You can export your data or delete your profile from Settings at any time.

AI and insights

Flousi may show deterministic insights based on the data you enter. External AI analysis is not required for the app to work and should be used only when explicitly configured and enabled. If there is not enough data, Flousi should say that instead of guessing.

How long data is kept

Your finance records live in your device or browser storage and are kept until you delete them. Clearing your browser data, resetting the app from Settings, or uninstalling removes them immediately. We hold no copy, so there is nothing for us to delete on your behalf and nothing to recover if you clear it - which is why the app offers an export.

If you created a Flousi profile, the account details described above are kept while the profile exists. When you delete your profile, the account record is removed and any residual authentication rows are cleared within 30 days. Error reports are scrubbed of finance data, not linked to your profile, and kept for at most 30 days.

Service providers we use

Flousi relies on a small number of processors to run the service. Supabase handles profile sign-in and stores the account details described above. Cloudflare provides website and application hosting, content delivery, and DNS, and so handles the network traffic between your device and Flousi. Neither receives your finance records in this release.

Currency rates are fetched by our own server rather than by your browser, so no request carrying your data reaches the rate provider. Other optional features may use documented external providers for market data, OCR, or similar utilities, and stay off unless you turn them on. Flousi shows source and unavailable states when provider data is missing. It does not invent live prices, balances, or financial values.

Reliability

Error reports: when something breaks in the app, Flousi sends an anonymous error report so it can be fixed. A report holds only the error type and message (scrubbed), the page, the app version, the browser family, the screen size class, and the device type and operating system version (for example "iPhone, iOS 18"). It never includes balances, amounts, transactions, account names, notes, messages, imported files, usernames or email addresses, and it is not linked to your profile. Reports are capped per device each day and kept for at most 30 days in Flousi's own infrastructure. You can turn error reports off at any time in Settings > Privacy & AI.

Receipt scanning and the Flousi assistant: when you scan a receipt or a balance screenshot, the photo is read on your phone and is never uploaded; only the amount, date, shop and VAT you confirm are saved. The assistant's tips and answers are worked out on your phone from your own records; your questions are not sent anywhere.

Export, deletion, and control

  • You can clear local app data from the app settings or your browser storage controls.
  • You can export app data where export tools are available.
  • If you created a profile, you can request deletion of that profile and its account details from Settings, or through the support contact below.
  • You should not send bank passwords, PINs, or full card numbers to support.
