Ultra-secure data encryption

Bracket uses a distributed, multi-layer AES-256 encryption design with automatic key rotation, ensuring state-of-the-art security for email data.

Lightning fast sign in without sacrificing security

Securely sign in without a password

Request to sign in using your email address, then click the secure link from your inbox. Bracket includes extra security measures, making it more secure than password logins.

Expiring, one-time-use links

Sign-in links expire 15 minutes after delivery and only work once.

Geolocation of sign-in requests

Sign-in request notifications include the requesting device IP and approximate location.

Advanced device fingerprinting

Sign-in links only work from the device that originally requested access. If a different device attempts to sign in, the link is invalidated and the session is blocked.

Send from any email client on any OS

Bracket allows sending encrypted email from any email client or operating system, including iPhone, Android, Windows, Linux, or PC.

No apps or plugins to install

To send an encrypted email with Bracket, just wrap the subject in brackets and send. No additional apps or plugins are required.

Ephemeral message storage

All data is temporary and there are no mailbox quotas. By default, messages expire in 1 year, but users can set messages to expire sooner.

Personal data keys

A personal data key gives users control of their encrypted message data. When enabled, all messages require the personal data key to decrypt, and this key is never stored in Bracket.

Journaling

Bracket allows seamless archive integration, enabling automatic journaling of data to an archive. The optional 'Export to Inbox' feature allows users to securely transfer messages to their normal email inbox.
