Privacy Policy
Last updated: March 17, 2026
What we collect
We only collect data necessary to operate the app:
- Account data — email address, display name (on signup)
- Expense data — receipts, amounts, merchants, categories, dates, currencies
- Mileage data — trip routes (start, destination, distance), if you use the mileage tracker
- Device data — browser type, OS (for error analysis)
- Usage data — page views, feature usage (via Google Analytics 4)
Why we collect it
- To provide and improve the expense tracking service
- To power AI receipt extraction and spending analysis
- To send transactional emails (password reset, subscription confirmation)
- To generate reports and exports for you
- To process payments via Stripe (we never see or store your card number)
What we don't do
- We never sell your data to third parties
- We never use your expense data for advertising
- We don't require bank account connections
- We don't track you across other websites
Third-party services
We use a small number of trusted services to operate Expense Lens. Each handles only the minimum data necessary.

| Google Analytics 4 | Anonymous usage analytics |
| Stripe | Payment processing |
| Resend | Transactional emails |
| Google Maps API | Route calculation (mileage tracker) |
Data retention
- Account data — stored while your account is active
- Receipt images — stored until you delete the expense or your account
- On account deletion — all data permanently removed within 30 days
Your rights
You can at any time:
- Unsubscribe from emails (link in every email)
- Export your data as CSV from the app
- Delete your account from app Settings → Delete account
- Request a copy or deletion of your data by email
For any privacy requests, email [email protected].
Cookies
The landing page uses Google Tag Manager for anonymous visit analytics. The app uses essential cookies for authentication only — no tracking cookies, no ad cookies. You can decline analytics cookies; the app works fully without them.
Changes
If we make significant changes to this policy, we'll notify you by email. Minor clarifications may be made without notice.
