Frosted — Privacy Policy
What Frosted reads
Frosted reads the visible text content of posts in your LinkedIn feed while the extension is enabled. It does this by reading the innerText of post elements rendered on your screen — the same text you can read yourself.
Frosted does not read:
- Your LinkedIn profile information
- Private messages or notifications
- Posts outside the feed (articles, company pages, search results)
- Any data from non-LinkedIn pages
Where processing happens
Entirely on your device.
- Pattern detection: Runs synchronously in the browser tab. No network request is made.
- Borderline posts: Posts that score in the ambiguous band are resolved by the same local pattern rules, using the score and your sensitivity setting. No model is consulted, no download occurs, and no network request is made.
Frosted itself makes no network requests and transmits no data.
What is stored locally
Frosted stores the following in chrome.storage.local (your browser's extension storage, private to your device):
| Key | Contents | Why |
|---|---|---|
frosted_settings |
enabled (bool), sensitivity (low/medium/high), feedbackButtonsEnabled (bool), betaBannerDismissed (bool), installTimestamp (number) |
Your preferences. feedbackButtonsEnabled is retained for backward compatibility and has no UI. |
frosted_stats |
totalScanned, totalFiltered, sessionStart, dailyFiltered, dailyDate |
The counts shown in the UI; no post content |
frosted_install_fp |
A 4-character random string (e.g., 7k2m) |
Per-install DOM prefix; not linked to your identity |
feedbackLog |
Array of up to 200 feedback entries. Each entry stores: feedback type (false-positive or false-negative), up to 500 characters of post text, pattern score, matched categories, classifier path (which detection path decided the post; always the pattern path in this version), sensitivity setting, AI reason (a field reserved for on-device AI, unused in this version), timestamp, extension version, and browser locale. Entries are added only when you explicitly click a feedback button. | FP/FN data for classifier improvement during beta |
Frosted does not store:
- Author names, profile URLs, or account identifiers
- Your browsing history or session data outside the feed
Frosted stores up to 500 characters of post text in your local browser storage only when you explicitly click a feedback button. This data never leaves your device, is capped at 200 entries, and can be viewed, exported, or cleared at any time from the side panel.
What is never collected
- No analytics
- No telemetry
- No crash reports
- No usage metrics
- No third-party SDKs in the extension
