PIN-Locked Access

Everything you need.
Nothing they can find.

Signal Protocol encryption meets invisible design. Messages, calls, groups, voice memos, photos, and video — all private at every layer.

PIN-Locked Privacy

Your messages are locked behind a secure PIN. No email, no phone number, no identity required. Just a PIN and a 12-word recovery phrase that only you control.

Signal-Grade Encryption

Every message is protected by the Signal Protocol — the same encryption trusted by journalists, activists, and security experts. Forward secrecy means even compromised keys can't unlock past messages.

Self-Destructing Messages

Every message automatically deletes after being read. Set timers from 5 seconds to 24 hours. A live countdown shows the exact moment it vanishes — from both devices.

Encrypted Voice & Video Calls

Make private voice and video calls with AES-256 encryption. Your calls are encrypted end-to-end — we never hear a word. Both users must have Pro for video.

PRO

Encrypted Group Chat

Create private group conversations with up to 50 members. Every message and photo is encrypted with rotating Sender Keys — if someone leaves, they lose access to future messages.

Voice Memos

Record and send encrypted voice messages that self-destruct like text. A visual waveform lets you scrub through playback. Slide to cancel if you change your mind.

Screenshot Protection

theSHFT blocks screenshots and screen recording inside the app. If someone tries to capture your screen, the other person in the conversation is notified instantly.

Duress PIN

Enter the duress PIN and theSHFT silently wipes all data — messages, contacts, encryption keys. No confirmation dialogs. No traces left behind.

PRO

Encrypted Photos & Video

Send photos and videos with the same encryption as text. In groups, media is encrypted with the group's Sender Key. Everything auto-deletes with the message timer.

Remote Wipe

Lost your phone? Trigger a remote wipe to erase all theSHFT data from the device. Your account can be restored with your 12-word recovery phrase.

Simple to use.
Impossible to intercept.

Frequently asked questions

How is theSHFT different from other messaging apps?

theSHFT uses the Signal Protocol for end-to-end encryption, requires no email or phone number to sign up, and every message self-destructs after being read. Your identity is protected from sign-up to send.

What happens if I lose my phone?

Your 12-word recovery phrase lets you restore your account on a new device. You can also trigger a remote wipe to erase all theSHFT data from the lost device. Without the recovery phrase, your data cannot be accessed.

Can theSHFT read my messages?

No. Messages are encrypted on your device before being sent. We use a zero-knowledge architecture — the encryption keys only exist on your device and your contact's device. We have no ability to decrypt your messages, even if compelled by law enforcement.

Can someone screenshot my conversations?

No. theSHFT blocks screenshots and screen recording inside the app. If someone manages to take a screenshot, the other person in the conversation is notified immediately. Your privacy is protected at every layer.

What is a Duress PIN?

The Duress PIN is your emergency option. When entered, it silently and immediately wipes all data — messages, contacts, encryption keys, account data — with no confirmation dialogs and no trace. The app returns to its fresh-install state. This is a Pro feature.

How do self-destructing messages work?

Every message you send has a timer. Once the recipient reads the message, the timer starts. When it reaches zero, the message is permanently deleted from both devices. Free users can set timers up to 60 seconds. Pro users can set timers up to 24 hours.

Do I need an email or phone number to sign up?

No. theSHFT uses a 12-word recovery phrase instead of email or phone verification. No personal information is required to create an account. You choose a username and that's it.

Are voice and video calls encrypted?

Yes. Voice and video calls are encrypted end-to-end with AES-256-GCM2. The encryption key is derived from the same key exchange used for messages — we never hear your calls. Voice calls are free. Video calls require Pro.

How does group chat encryption work?

Group messages use Sender Keys — each member generates a unique symmetric key that's distributed to the group. When a member is removed, all keys automatically rotate so they can't decrypt future messages. Groups support up to 50 members.

Is theSHFT available on Android?

theSHFT is currently available on iOS (iPhone, iPad, and Mac with Apple Silicon). Android support is planned for a future release.
