SMS Tech
Private SMS / MMS app with voice messages, encrypted vault, biometric unlock.
新版本 1.28.14
Maintenance release: nothing changes in how the app works.
The app no longer requests BROADCAST_WAP_PUSH. Android grants it only to the system, so the request did nothing; receiving MMS is unaffected.

SMS Tech is an ad-free, tracker-free SMS / MMS app for Android. It replaces the stock messaging app while keeping every message on your device — no cloud, no analytics, no third-party SDK shipping your data anywhere.

Features
- SMS and MMS — full default-SMS-app support on Android 8 (API 26) through 15+
- Voice messages — push-to-talk recording sent as a real MMS, capped at 60 s / 300 KB so every carrier accepts it
- Encrypted vault — hide sensitive conversations behind SQLCipher, with the key wrapped in the Android Keystore. Toggle "Lock vault on leave" to re-lock it every time the app goes to background
- Decoy PIN — a second PIN that opens the app in a decoy view where the vault stays invisible and inaccessible
- Emergency mode — hold the button for 3 s to send an alert SMS to your Safety Call contacts, with a single GPS fix if you granted location; without that permission the SMS still goes out, only without coordinates. Quick access to the emergency numbers of the country your phone is connected to, and shortcuts on the lockscreen notification. Placing the call directly is opt-in: by default the dialer simply opens pre-filled
- Biometric unlock — fingerprint or face, with a PIN fallback you set yourself
- Contextual reply — long-press a message, pick "Reply" and your composer shows a mini-quote so the recipient sees what you are answering
- Delegated translation — long-press a message and pick "Translate" to hand the text to whichever translation app you have installed (Google Translate, DeepL, Aves Translate …) through a system Intent. No translation model is bundled, and SMS Tech itself sends nothing anywhere
- Scheduled messages — write an SMS, pick a date and time, and it is sent at that moment even if the app is closed
- OS-wide blocked numbers — at first launch, SMS Tech mirrors the system blocklist (Phone app, Samsung Messages) and retroactively deletes the conversations that match
- Attachment picker — Photo, Video, File, Contact card. Photos are automatically re-encoded as JPEG to fit MMS carrier caps
- Full-text search across every conversation, with FTS4 indexing
- Export a conversation as a PDF for archival
- Encrypted local backup using a passphrase distinct from your unlock PIN
- Themes — Light / Dark / AMOLED / "Dark Tech" slate-blue accent
- English, French, German, Italian and Spanish UI
- Confirmation toggle in Settings → Send → "Confirm before send" requires a confirmation dialog before any SMS, MMS or attachment is dispatched
Privacy
- No analytics, no crash reporters, no third-party tracking SDK
- No network access: SMS Tech does not hold the Internet permission; Android's own MMS service carries MMS. Nothing but your messages leaves the phone
- Location and phone-call permissions serve Emergency mode only. Both are opt-in, neither is ever used in the background, and the app works without granting either
