Privacy Policy
For the SlopRadar Chrome extension.
Last updated: May 28, 2026
Scope of this policy
This policy covers only the SlopRadar Chrome extension — a browser extension that uses Chrome's on-device Gemini Nano model to detect AI-generated marketing slop in your social feeds.
The FeatureBoard web application has its own separate policy at featureboard.ai/privacy. SlopRadar does not share infrastructure, data, or analytics with that product.
TL;DR
SlopRadar does not collect, transmit, sell, or share any of your data. Everything happens locally inside your own browser. There are no servers, no analytics, no tracking, and no third parties involved in any classification.
1. What the extension processes
To detect AI-generated slop in your social feeds, SlopRadar reads the text of posts on the supported sites (LinkedIn, X/Twitter, Reddit, and Threads) and classifies each post using Chrome's built-in, on-device Gemini Nano model. This classification runs entirely on your device. Post text is never sent over the network by this extension.
2. What is stored, and where
The extension stores the following using Chrome's local extension storage (chrome.storage.local), which lives only on your device:
- Your settings — display mode, confidence threshold, theme, excluded sites.
- The slop-detection pattern list, including patterns you add or that are learned from your Confirm slop / Not slop feedback.
- Short text fingerprints created when you right-click a post to flag it.
- Cached classification verdicts (hashed text → verdict) so reopening your feed is responsive — these are pruned after 7 days and capped at 2,000 entries.
- Aggregate counters (how many posts were checked and hidden) for the stats panel.
- A rolling local log used by the in-extension Logs panel for debugging.
None of this is transmitted anywhere. Uninstalling the extension removes it.
3. What is NOT collected
- No personal information, account details, or credentials.
- No browsing history.
- No data sent to the developer or any third party.
- No advertising or tracking identifiers.
- No telemetry, crash reports, or usage analytics of any kind.
4. AI processing
Classification is performed by Chrome's built-in Gemini Nano model, which runs on your device. SlopRadar does not call any external AI service. The model itself ships with Chrome and is governed by Google's terms for that model — not by SlopRadar.
5. Permissions and why they are requested
- Host access (LinkedIn, X/Twitter, Reddit, Threads) — to read post text on those sites and visually hide detected slop.
- storage — to save your settings, patterns, and cached verdicts locally.
- scripting / tabs — to run the detector on supported tabs and reflect the on/off state in the toolbar icon.
- contextMenus — to provide the right-click Mark as slop menu item.
6. Your rights
Since SlopRadar holds no data about you outside your own browser, there is nothing on our side to access, correct, or delete. You can clear everything the extension stores by either using its settings (Clear patterns, Clear log) or uninstalling the extension.
