    Get started in seconds:

    Most data leaks don't happen through sophisticated attacks. They happen when someone pastes an API key into a team chat, leaves credentials in a project tracker comment, or sends a contract draft to an AI assistant. Locki encrypts the sensitive parts before they leave your control — right inside the apps your team already uses, with a single right-click.
    
    ⚫ AES-256-GCM encryption
    Every piece of text you encrypt with Locki is protected using AES-256-GCM — the same standard trusted by banks and government systems. Encryption happens entirely in your browser. Plaintext never leaves your device.
    
    ⚫ Zero-knowledge architecture
    Locki is built so that we never have access to your data. Keys are never transmitted or stored in plaintext on our servers. Even with full database access, Locki cannot read what your team has encrypted.
    
    ⚫ Works inside every browser-based app
    Locki works directly inside any web app without integrations, APIs, or workflow changes — whether it's a messaging platform, email client, project tracker, document editor, or support tool. Select text, right-click, encrypt. That's it.
    
    ⚫ AI data leak prevention
    When your team pastes customer records into an AI assistant, that content leaves your organization's control entirely. Locki lets you encrypt the sensitive parts of a prompt before submitting — so your team can use AI tools without exposing what shouldn't be exposed.
    
    ⚫ Smart Suggestions — automatic sensitive data detection
    Locki detects unencrypted sensitive patterns before you send them: credit card numbers, API keys, SSNs, and custom patterns defined by your admin. It works as a lightweight DLP layer inside every app, without requiring a separate tool.
    
    ⚫ Centralized key management for teams
    The admin dashboard gives security leads full control over shared encryption keys, user access, and group-based permissions. Scope keys by team or role — finance, engineering, legal — so each group only accesses what they need.
    
    ⚫ Full audit trail
    Every encryption, decryption, key rotation, and access change is logged with actor, timestamp, and context. No plaintext content is ever stored — only metadata. Built for compliance visibility without compromising privacy.
    
    ⚫ Key rotation with version history
    Rotate encryption keys at any time without breaking existing encrypted content. Previous key versions are retained so nothing becomes inaccessible, and access can be revoked instantly for any individual or group.
    
    ⚫ GDPR-compliant by architecture
    No tracking, no behavioral data collection, no plaintext storage. Locki's compliance posture comes from how it's built, not from a policy document.
    
    Install the extension, sign in with your organization account, and your team's encryption keys sync automatically. Setup takes a few minutes, and your team can start encrypting right away.
