Clear SMS is an open-source, privacy-first SMS app that automatically organizes your inbox - completely offline, on your device.

Smart inbox

Messages are automatically sorted into Important, Promotional, Personal, OTP and Unknown using a transparent, regex-based rules engine - no ML black box, every rule is human-readable JSON you can inspect and edit.
390+ community-maintained rules plus a 715k sender-ID directory.
Full-text search with category and time filters, heuristic scam-awareness flagging.

Finance dashboard

Debit/credit transactions are extracted from bank SMS into accounts, credit cards and spend summaries with hand-rolled charts.
Balance tracking with an optional biometric balance lock.

Bills and alerts

Upcoming bills, autopay, insurance and credit-card due dates in one Alerts view.
Train and flight journeys, package deliveries with courier and tracking id.

Messaging

Full SMS send and receive (default-SMS-app role), MMS send and receive with on-device image compression.
Dual-SIM support, message scheduling, drafts, delivery reports, pinned conversations.
Recycle bin with 30-day retention, undo for delete and archive, blocked senders and keywords.

OTP handling

Big, copyable OTP notifications, optional auto-copy and configurable auto-delete.

Private by design

No INTERNET permission - no servers, no telemetry, no analytics, no trackers.
No Firebase, no Play Services - pure AOSP compatible.
Local backup and restore for messages and settings; your data never leaves your device.
The only network activity is the Android system's own MMS transaction with your carrier - inherent to how MMS works.

Material You - dynamic color on Android 12+, light/dark/system themes.
