Privacy Policy

Best Password Generator (Chrome extension) · Effective November 6, 2026

Short version: Best Password Generator does not collect, transmit, sell, or share any data. It makes no network requests. Everything it stores stays on your device, encrypted.

What the extension stores

Only on your device, inside Chrome's storage for this extension:

Both are encrypted with AES-256-GCM before they are written to disk. The encryption key is created on your device, is never transmitted, and is stored so that no script can read its raw bytes. Nothing is synced to your Google account. Removing the extension deletes all of it.

What the extension does not do

Web pages

The extension has no standing access to any website. When you right-click a field and choose Fill new password, Fill new memorable password, Fill new passphrase, or Fill new username, Chrome grants it temporary access to that one tab. It uses that access only to write the generated value into the field you clicked (and an empty confirm-password field right after it in the same form), and to show a brief "filled and copied" message. The only things it looks at are which field you clicked and whether the next password field is empty. Nothing from the page is stored or sent anywhere.

Permissions and why they are needed

PermissionUsed for
storageSaving your settings and optional history, encrypted, on your device.
clipboardWriteCopying a generated value when you click Copy, press a copy shortcut, or use a Fill command.
contextMenusAdding the Fill commands to the right-click menu on text fields.
activeTabTemporary access to the current tab, only after you choose a Fill command.
scriptingWriting the value into the field you clicked and showing the confirmation, within that temporary access.
offscreenCopying to the clipboard for Fill commands (the background script cannot access the clipboard directly). Closed right after each copy.

Randomness

Values are generated with your browser's cryptographically secure random number generator (crypto.getRandomValues). Passphrases and real-word memorable passwords use the EFF Large Wordlist, which is bundled inside the extension. Made-up words are built from random syllables on your device.

Changes

If this policy changes, the new version will be posted at this address with a new effective date. Because the extension collects no data, changes cannot affect data already collected about you: there is none.
