Effective Date: 08 Sep 2025
Thank you for using Laffu, your personal offline expense tracker.
We respect your privacy and are committed to keeping your information safe, private, and fully under your control.
This Privacy Policy explains what permissions our app uses, why they are needed, and how your data is handled.
All SMS and contact data stays on your device only.
We do not upload, store, or share your personal information with any server or third party.
You remain in full control of your data β uninstalling the app deletes everything.
RECEIVE_SMS, READ_SMS, SEND_SMS, RECEIVE_MMS, RECEIVE_WAP_PUSH
Why we need them:
To detect and categorize bank transaction alerts from SMS/MMS messages.
To show you a complete SMS inbox experience inside the app.
To allow you to send replies directly from the app.
How we use them:
We only analyze SMS messages that come from banks/financial institutions.
All analysis happens locally on your device β no SMS content ever leaves your phone.
Other SMS (personal chats, OTPs) remain untouched unless you open them in the inbox.
Android only allows the default SMS app to access SMS and MMS data.
For Laffu to automatically track your bank messages and show you an inbox, it must be set as your default SMS app.
You can change this setting back to your original SMS app anytime in your device settings.
READ_CONTACTS
Why we need it:
To display sender names in your SMS inbox and conversation list.
How we use it:
Contacts are only used for local name matching.
We do not upload, share, or store your contact list.
POST_NOTIFICATIONS
Why we need it:
To notify you when new SMS messages arrive.
To alert you of newly detected transactions.
How we use it:
Notifications are generated and managed only on your device.
android.hardware.telephony
The app requires telephony features because it needs access to SMS and MMS messages to function as an expense tracker.
Local Only: All data (SMS, contacts, transactions, budgets) stays on your device.
No Cloud Storage: We do not collect, store, or upload any of your data to external servers.
No Third Parties: We do not share your information with advertisers, marketers, or other companies.
Data Deletion: Uninstalling the app removes all your local data.
Your privacy comes first β the app was designed to work offline by default.
You stay in full control of your messages, expenses, and contacts.
We only request permissions that are strictly necessary for the app to function as both an SMS app and an expense tracker.
If you have any questions about this Privacy Policy or how your data is handled, please contact us at:

β This policy reassures users why each permission is needed and makes it clear to Google Play that:
Youβre compliant with their SMS/Contacts sensitive data requirements.
Youβre transparent about being the default SMS app.
No personal data leaves the device.
