1. Commitment to Privacy
This Privacy Policy explains how SMS Organizer ("App", "Application", "we", "our", or "us"), developed by Mathankumar S, handles information when you use our mobile application on Android devices.
Strict Zero-Data Collection Principle: We do NOT collect, store, track, monitor, monetize, sell, or transmit any of your personal data, text messages, contacts, phone numbers, or OTP codes to any external servers, cloud databases, or third-party service providers. All processing is performed strictly offline on your own device.
2. Architecture: 100% On-Device & Offline-First
SMS Organizer is purposefully engineered as an offline-first, client-only application. The App does not contain network synchronization backends, remote databases, or cloud accounts. When you open SMS Organizer:
- Your messages are read directly from your Android device's built-in system telephony database (
content://sms,content://mms). - All message categorization (Personal, Transactions, Banking, OTPs, Offers, Spam) is evaluated dynamically on your device's local CPU using regular expressions and rule-based heuristic filters.
- No machine learning models, telemetry packets, or diagnostic logs containing user text or phone numbers are ever dispatched across the Internet.
3. Android Permissions & How They Are Used
To function as your primary SMS client and provide smart organizer features, SMS Organizer requests specific Android permissions. Each permission is used solely for the stated purpose directly on your device:
| Permission | Android Constant | Purpose & Usage |
|---|---|---|
| Default SMS / Receive SMS | RECEIVE_SMS, BROADCAST_SMS |
Required to intercept incoming text messages, classify them into appropriate categories, and notify you in real-time. |
| Read & Write SMS | READ_SMS, WRITE_SMS, RECEIVE_MMS |
Allows the App to display your past conversation threads, mark messages as read, delete unwanted messages, and manage SMS drafts. |
| Send SMS | SEND_SMS |
Enables composing and sending SMS and MMS messages directly through your active SIM card. Standard carrier messaging charges apply. |
| Read Contacts | READ_CONTACTS |
Used strictly on-device to resolve phone numbers into contact names and display avatars for saved contacts. Contacts data never leaves your device. |
| Post Notifications | POST_NOTIFICATIONS |
To display system notifications and head-up banners for incoming messages, complete with quick action buttons (Copy OTP, Mark as Read, Direct Reply). |
| Exact Alarms | SCHEDULE_EXACT_ALARM |
Used exclusively to schedule local on-device cleanups for expired OTPs if you enable the optional Auto-Delete OTP feature in App Settings. |
| Phone State | READ_PHONE_STATE |
Used only to identify dual SIM subscriptions so you can choose which SIM card to send text messages from. |
4. On-Device Categorization & Sensitive Information
SMS messages frequently contain highly sensitive information such as One-Time Passwords (OTPs), bank balance alerts, credit card transaction receipts, and personal correspondence.
Here is how we safeguard this information:
- No Cloud AI or Remote Processing: Categorization does not rely on third-party cloud AI or external APIs. All heuristics execute locally in the app process.
- One-Tap OTP Copy: When an OTP is recognized locally, the App offers a convenient "Copy OTP" button in the notification and UI. The code is placed into your device clipboard only upon your action or system settings preference.
- No Financial Account Linking: SMS Organizer never asks for your bank credentials, passwords, PINs, or UPI access. It merely reads standard plain-text SMS notifications sent by your bank or service provider.
5. Data Storage, Retention & Deletion
You maintain complete, absolute ownership of your data at all times:
- Standard Telephony Storage: Messages are stored in the Android OS standard Telephony provider. Deleting a message in SMS Organizer deletes it permanently from your device storage.
- Preferences & Settings: Your application preferences (such as Dark/Light theme, default SIM preference, delivery report toggles, and notification settings) are saved in your private on-device
SharedPreferencesstorage. - Auto-Delete OTP: If enabled, the App runs a local background worker to permanently remove OTP messages that exceed your selected retention window (e.g., 24 hours, 7 days, 30 days).
- App Uninstallation: If you uninstall SMS Organizer, all private app preferences are wiped immediately by the Android operating system. Your SMS messages remain safely in your Android system telephony database for other SMS apps to access.
6. Third-Party Libraries and Advertisements
SMS Organizer does NOT include:
- Any third-party advertising SDKs (e.g., Google AdMob, Unity Ads, Meta Audience Network).
- Any third-party user behavior or behavioral tracking trackers (e.g., Firebase Analytics, Adjust, AppsFlyer, Mixpanel).
- Any background data selling, scraping, or analytics syndication partners.
The Application is built entirely with official Google Android Jetpack libraries and open-source Android architectural components.
7. Children's Privacy (COPPA & GDPR Compliance)
SMS Organizer does not address or knowingly collect data from children under the age of 13 (or under 16 in the European Union). Because we collect zero personal data from any user regardless of age, our practices fully comply with the Children's Online Privacy Protection Act (COPPA) and international child privacy regulations.
8. Security Safeguards
Because SMS Organizer operates strictly offline, your data is never exposed to remote server breaches or man-in-the-middle network interceptions. Security is safeguarded by:
- Android's application sandboxing architecture, ensuring no other application can access SMS Organizer's private internal storage without root privileges.
- Your device's hardware-backed encryption, lock screen PIN/biometric authentication, and operating system updates.
9. Changes to this Privacy Policy
We may update this Privacy Policy from time to time to reflect operational, legal, or regulatory updates. Any changes will be published here with an updated "Effective Date." We encourage you to review this page periodically.
