What the app stores on your device

Family Budget AI stores most budgeting data locally on your device so the app can work as your personal or household planner.

  • Budget data such as bills, income, sections, pots, debts, clubs, school costs, travel, and other entries you add.
  • Household setup information such as adult and child names, emojis, and section preferences.
  • App settings such as theme, layout, language, currency, footer shortcuts, hidden sections, reminder preferences, and sync settings.
  • Your app passcode is not stored in plain text. A hashed form is stored locally if you enable the passcode lock.
  • If you choose to use receipt AI with your own provider key, that key is stored locally on your device unless you remove it.

What is sent to our server

You can use Family Budget AI locally without turning on partner sync. If you enable partner sync, selected household data is sent to our secure server so linked devices can stay in sync.

  • Shared household budget data and sync timestamps.
  • Temporary pairing data used to create and join one-time link codes between devices.
  • Basic technical request data needed to operate, secure, and rate-limit the service.

We do not provide a public account system in the current app version. The sync service exists to keep linked household devices in step with each other.

Receipt AI and third-party AI providers

Receipt AI is optional. It only runs when you actively use the receipt scan feature and add your own AI provider key.

  • When enabled, receipt OCR text, the current draft receipt details, and allowed budget sections may be sent through our server to the AI provider you selected.
  • Supported providers may include OpenAI, Anthropic, Google, OpenRouter, Groq, DeepSeek, or another provider you choose in the app.
  • Your provider key is supplied by you and is not a server master key from us.

If you do not enable receipt AI, receipt categorisation stays manual and no receipt text is sent to a third-party AI provider through this feature.

Notifications

Bill reminders are scheduled locally on supported native devices. They use your device notification permission and do not currently rely on remote push delivery from our server.

Payments

Where the app is sold through an app store, purchase processing is handled by the relevant store platform and its payment systems. We do not receive your full payment card details inside the app.

What we do not intentionally collect

  • We do not use in-app advertising.
  • We do not intentionally collect your precise location.
  • We do not provide a public social feed or public profile system.

How long data is kept

  • Local app data stays on your device until you delete it, clear app/browser storage, or remove the app.
  • If you use partner sync, shared household data remains on the sync service until it is replaced, unlinked, or you request deletion.
  • Temporary pairing codes are short-lived and expire automatically.

Your choices

  • You can use the app locally without partner sync.
  • You can remove your AI provider key from the app settings at any time.
  • You can turn reminders off in the app and in your device settings.
  • You can unlink a synced device from the shared household in the app settings.

Data access, deletion, and questions

Changes to this policy

We may update this policy from time to time as the app, store requirements, or legal obligations change. The latest version will always be available at this page.
