Leakless is a Chrome extension that detects and masks secrets, credentials, and personally identifiable information (PII) in text you paste or select — so you can share a safe version in Slack, Jira, GitHub, or an AI chat. Leakless runs entirely on your device. It does not collect, upload, transmit, or store any of the text you redact.
When you paste text into the Leakless popup or use the right-click "Copy redacted" menu, the text is analyzed by detection patterns bundled inside the extension. All of this happens locally in your browser. The text you enter and the redacted output are never sent to any server, and Leakless retains no copy of either.
chrome.storage.local and never leave your browser.If you choose to activate a Leakless Pro license, the extension contacts Lemon Squeezy once to verify your license key. This request sends only your license key — it contains no text you have pasted, no detected secrets, no browsing data, and no personal information beyond the key itself. After activation, Pro status is stored locally and the extension does not contact any server again.
No other network request is ever made. There is no telemetry, no analytics endpoint, and no remote code loading.
