Privacy Policy

Last updated 10 November 2026

Keen is a personal budgeting app for iPhone and iPad. It keeps your balance and budget up to date from your bank alerts, statements and receipts. This policy explains what Keen reads, where it is kept and what it is never used for.

The short version

Keen has no account system and no server of its own. Your data stays on your devices and in your own iCloud account.
Keen does not sell your data, show ads, or use analytics or tracking tools.
Connecting Gmail is optional and read-only.

What Keen stores

Transactions, balances, budgets, receipts and settings you add or that Keen finds for you. They are stored on your device and, if iCloud is on, synced through your private iCloud database using Apple's CloudKit. If you share a household budget, only the budget you choose to share is visible to the people you invite.

Data from Google (Gmail)

If you choose to connect a Gmail account, Keen asks for the gmail.readonly permission. Keen uses it only to find money-related emails you already receive: bank payment alerts, purchase receipts, order confirmations, invoices and subscription notices.

Where it's read: emails are fetched directly from Google to your device and read there. They are not sent to any Keen server or to any other party.
What's kept: only the details Keen finds, such as the amount, date, shop and items. Keen does not keep copies of your emails.
Sign-in: your Google sign-in token is kept in your device's Keychain.
Read-only: Keen cannot send, delete, label or change your email.
Never used for advertising, never sold, never transferred to others, and never used to train AI models.

Keen's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

On-device intelligence

Where available, Keen uses Apple's on-device model to help read emails and receipts. This runs on your device; nothing is sent elsewhere.

Other services Keen contacts

When you use certain features, Keen contacts a service directly from your device: a restaurant's own website to read its menu when you plan an outing, a map service to find the place, and some retailers' websites to show a photo of an item on your receipt. Only what's needed for that lookup is sent, such as a place or product name.

Deleting your data

Disconnect Gmail in Keen's Email settings, or remove Keen at myaccount.google.com/permissions.
Deleting Keen removes its data from your device. To remove synced data, delete Keen's data under iCloud in your device's Settings.
