Privacy Policy
Effective 12 August 2026 · applies to the LLM Masker Chrome extension
What LLM Masker does
LLM Masker scans the text of prompts you write on supported AI chat sites (ChatGPT, Claude, Gemini, Copilot, DeepSeek, Perplexity, Google AI Mode) and replaces detected secrets and personal data — API keys, AWS credentials, JWT tokens, emails, phone numbers, credit card numbers, US Social Security numbers — with a safe placeholder before the prompt is sent. Detection runs entirely on your device using pattern matching. There is no account, no sign-up, and no analytics.
Data we do not collect
- Prompt content — never transmitted anywhere. Scanning happens locally; there is no network call in the scan path.
- Matched values — the secrets the extension detects are never stored, logged, or transmitted. Not even locally.
- Browsing activity, analytics, telemetry — none. The extension contains no analytics or tracking code of any kind.
- Personal information — we have no servers holding user data, and no user accounts.
What is stored on your device
The extension keeps a small amount of data in Chrome's local extension storage, on your device only:
- Your settings — the on/off state, detector choices, and masking-timing preferences.
- Masking statistics — a total count and a short recent-activity log holding only the type of each detection (e.g. "Email Address") and a timestamp. Capped at 50 entries and 30 days. The matched value itself is never stored.
- A random install identifier — generated locally and kept locally; it is not transmitted.
- A PRO licence token, if you purchase PRO.
You can erase the statistics at any time with Settings → Clear activity data, and everything is deleted when you uninstall the extension.
The one network request
If — and only if — a PRO licence is stored, the extension periodically contacts api.llmmasker.com to verify that licence. This request carries the licence token and nothing else: no prompt content, no browsing data, no personal information. Without a PRO licence, the extension makes zero network requests. Fonts and all assets are bundled inside the extension, so nothing is fetched from third parties.
Permissions we request, and why
storage— save your settings and the local statistics described above.offscreen— run pattern matching off the page's main thread so chat sites stay responsive.alarms— schedule the periodic PRO licence re-check.- Site access to the seven supported AI chat surfaces (including Google Search's AI Mode) — required to scan and mask your prompt on those pages. On google.com the extension touches only the AI Mode composer, never ordinary Search.
Data sharing and selling
We do not share, sell, or transfer any user data to anyone. There is nothing to share — the data never reaches us.
Children's privacy
LLM Masker is a general-audience developer tool and does not knowingly collect any information from anyone, including children.
Changes to this policy
If we change this policy, the new version will be posted at this address with an updated effective date. Material changes to what the extension does with data will also be noted in the extension's release notes.
