What FundsFlow is

FundsFlow is a private personal ledger for recording money you send, receive, or pass along within your own circle of friends. It is not a payments app, a bank, a lending product, or an investment product — it does not move money on your behalf. This policy explains what information the app and its backend collect, why, and how it is protected.

Information we collect

  • Phone number — used solely to verify your identity via Firebase Authentication OTP sign-in. We never see or store your OTP code.
  • Friend records you create — names, optional phone numbers, and optional notes for the people in your ledger.
  • Transaction records you create — sender, receiver, amount, date, optional note, and optional reference ID.
  • Stock or IPO holdings you record — company name, optional quantity, amount invested, and the purchase and sale dates.
  • Attachments you choose to upload — receipt images or PDF files attached to a transaction. The app only ever reads the specific files you pick; it does not scan your gallery or storage.

Friend records can contain details about other people. You enter those yourself, and it is on you to have their agreement to record them. FundsFlow never contacts them, and they have no account or visibility here.

What we don't collect

  • We do not access your contacts, SMS, call logs, or any data outside what you manually enter into the app.
  • We do not collect location data.
  • We do not use advertising identifiers or run ads.

How your information is used

Your data exists only to power your own ledger. It is never shared with the friends you record transactions about, never sold, and never used for advertising. Every request to our backend is authenticated and scoped to your account — there is no code path where one user's ledger is visible to another user.

Where your data is stored

  • Firebase Authentication (Google) — verifies your phone number and issues your sign-in session. We do not store your OTP.
  • Supabase PostgreSQL — stores your friends, transactions, and account records, behind a backend that authenticates every request.
  • Supabase Storage — stores attachment files in a private bucket. Files are never public; access requires a short-lived signed link generated on demand.

These are the only third parties that process your data, and each is used strictly as infrastructure — none of them has independent access to use your data for their own purposes.

On your device

If you add a FundsFlow home screen widget, the figures it shows are kept on your device so it can draw them without opening the app. They sit in the app's own private storage, are not readable by other apps, and are wiped when you sign out. Do note that a widget puts your totals on your home screen, where anyone holding your phone can read them.

The app also opts out of Android's automatic backup, so its data is not copied to your Google account.

Exports and sharing

You can export your whole ledger as a CSV file, or share one friend's transactions as a PDF. Those files are produced on your device at your request and go wherever you choose to send them. Once shared, a file is outside the app's control and no longer covered by this policy.

How your data is protected

  • Traffic between the app and the backend is encrypted in transit over HTTPS.
  • Every request is verified against your Firebase sign-in and scoped to your account before any data is read or written.
  • Attachments live in a private storage bucket and are reachable only through a short-lived signed link created on demand.
  • The app contains no analytics, crash reporting, advertising, or tracking SDKs of any kind.

Data retention and deletion

Your data is retained for as long as your account exists. You can permanently delete your account and all associated data at any time from within the app, or by following the steps on our account deletion page. Deletion is immediate and permanent — we do not retain backups of deleted accounts.

Children's privacy

FundsFlow is not directed at children and is not intended for use by anyone under the age required by applicable law to manage their own account.

Changes to this policy

If this policy changes, the "last updated" date above will change with it. Material changes will be reflected here before they take effect.
