Privacy Policy

SmartExpense · Last updated: June 3, 2026

SmartExpense (“we”, “our”, or “the app”) helps groups track shared expenses and settle balances. This policy explains what information we collect, how we use it, and your choices. By using SmartExpense, you agree to this policy.

1. Information we collect

Account information — When you sign in with Google, we receive your name, email address, profile photo URL, and a unique user ID from Firebase Authentication.
Expense and room data — Room names, member lists, expenses, splits, settlement records, notes, and amounts you enter are stored in Google Firebase Firestore so your group can collaborate in real time.
Receipt and bill images — If you attach a photo for an expense or settlement proof, the image is compressed on your device and uploaded to our image hosting service. Images are associated with a room ID and used only to display receipts to room members.
Device and push tokens — We store Firebase Cloud Messaging (FCM) tokens to send notifications about settlements and room activity. We may also collect basic device information required by Firebase services.
App preferences — Theme choice and similar settings may be stored locally on your device.

2. Information we do not collect

We do not process or store UPI/bank payments inside the app.
We do not collect your UPI ID, card numbers, or banking credentials.
When you tap Pay, Android opens your chosen UPI app on your phone. That payment happens entirely outside SmartExpense.

3. How we use your information

Authenticate you and keep your account secure
Sync expenses, balances, and settlements with people in your rooms
Display receipt images to room members
Send push notifications about settlements and updates
Deliver app updates (including over-the-air patches via Shorebird)
Improve reliability and fix bugs

4. Permissions on Android

Camera — To take photos of bills and settlement receipts.
Photos / media — To pick existing images from your gallery for bills and proof of payment.
Notifications — To alert you about settlement status and room activity.
Internet — Required to sync data and upload images.
Installed UPI apps (queries) — Used only to show Android’s “Pay with” chooser so you can pick GPay, PhonePe, Paytm, or another UPI app. We do not read your installed apps list for advertising or tracking.

5. Third-party services

SmartExpense uses trusted third-party services that process data on our behalf:

Google Firebase — Authentication, Firestore database, Cloud Messaging
Google Sign-In — Account login
Cloudflare Workers — Secure image upload and delivery for receipts
Shorebird — App update delivery

Each provider has its own privacy policy. Firebase: firebase.google.com/support/privacy

6. Data sharing

Expense and settlement data in a room is visible to members of that room. We do not sell your personal information. We may disclose data if required by law or to protect the rights and safety of users.

7. Data retention and deletion

Data remains in Firebase while your account and rooms exist. If you delete your account or leave all rooms, associated personal data can be removed upon request. Uploaded receipt images may remain until manually deleted or until the room is removed.

8. Security

Data is transmitted over HTTPS. Firebase security rules restrict access so only authenticated room members can read room data. No method of storage is 100% secure, but we take reasonable steps to protect your information.

9. Children

SmartExpense is not directed at children under 13. We do not knowingly collect data from children.

10. Your rights

Depending on your location, you may have the right to access, correct, or delete your data. Contact us using the email below.

11. Changes

We may update this policy. The “Last updated” date at the top will change when we do. Continued use of the app means you accept the updated policy.
