LockiSecurity
Locki encrypts any text you select — passwords, notes, personal data — before it ever leaves your browser.
Passwords shared in chats. Personal notes stored in web apps. Drafts that auto-save to the cloud. Sensitive text is exposed at every step of a normal digital workflow — usually without the user realizing it.
Teams regularly share passwords in Slack, email, or notes. These platforms store everything unencrypted and readable by admins.
Notes apps, documents, and drafts are synced to cloud servers. A breach of the cloud provider exposes your content.
Draft emails and documents auto-save to servers before you've even decided to share them. That data is accessible to the provider.
Forms collect data before submission. Trackers, injected scripts, and browser extensions can read that text as you type it.
Select the sensitive text in any field and encrypt it with Locki before saving or submitting. Only the encrypted version is stored.
Inputs, textareas, rich-text editors, note apps — Locki works in any browser-based text field.
Each encryption uses a unique random key parameter. Even encrypting the same text twice produces different output.
Encrypted text stays as ciphertext until you click it. Locki reveals it for a short period, then automatically hides it again.
How it works
01
Enter any sensitive content — a password, personal data, or confidential note — in any web field.
02
Highlight the text, right-click, and choose "Encrypt with Locki". The text is replaced with encrypted ciphertext immediately.
03
Save the document, submit the form, or share the text. Only the encrypted version is stored or transmitted.
04
Click the [lockied] placeholder anytime to reveal the original text for a short period. It hides automatically after that.
Common use cases
Encrypt passwords before sharing them in Slack, email, or any collaboration tool. Even if the message is leaked, the password stays safe.
Keep private notes encrypted in Notion, Obsidian Web, or Google Docs. Only you — and people with your key — can read them.
Encrypt sensitive sections of in-progress documents before they're auto-saved to the cloud. Protect the content at the source.
Encrypt API keys, tokens, and access credentials before pasting them into tickets, wikis, or chat messages.
Protect ID numbers, account details, and financial information before entering them in web forms or sharing them online.
Encrypt the parts of a conversation that need to stay between specific people — regardless of which platform you use.
Locki uses AES-256-GCM with a unique IV per operation. All encryption runs in your browser using the Web Crypto API. Your key never leaves your device, and Locki's servers never see your plaintext. See our full security architecture for technical details.
