Locki Firefox

Locki

Protect PII and sensitive information in any web app. Professional-grade encryption that fits perfectly into your team's workflow.

Features & Capabilities

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.

Is Locki Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Locki requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Locki is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
