Privacy Policy
Last updated: June 8, 2026
The short version: ReviewLenz collects Trustpilot reviews through your browser session, sends them to our server for AI analysis, and returns a report. We do not sell your data, track your browsing, or store personal information beyond what is needed to deliver the service.
1. What ReviewLenz Does
ReviewLenz is a Chrome extension that helps you analyse customer reviews on Trustpilot. When you initiate a scan, the extension:
- Opens Trustpilot review pages in background tabs using your logged-in browser session
- Extracts publicly visible review data (rating, text, date, title) from those pages
- Sends the collected reviews to our analysis server for AI processing
- Returns a structured intelligence report displayed in a local browser tab
2. Data We Collect
Review data: When you initiate a scan, we temporarily process the review text, rating, date, and title from Trustpilot pages. This data is publicly available on Trustpilot.
Technical data: A randomly generated session identifier (not linked to your identity) is used to route your scan results back to your browser. No IP addresses, names, emails, or personal identifiers are collected during scans.
What we do NOT collect:
- Your Trustpilot login credentials
- Your browsing history outside of Trustpilot review pages
- Personal information from your Trustpilot account
- Cookies, passwords, or authentication tokens
- Data from any website other than Trustpilot review pages you explicitly scan
3. How We Use Your Data
Collected review data is used exclusively to:
- Generate AI-powered analysis reports (sentiment, themes, NPS, action plans)
- Power the conversational AI chat feature within your report
- Cache results temporarily (up to 24 hours) to avoid redundant processing
We do not use review data for advertising, profiling, training AI models, or any purpose other than delivering your analysis report.
4. Data Storage and Retention
- Analysis results may be cached on our server for up to 24 hours to improve performance for repeat lookups of the same brand.
- Raw review text is not permanently stored on our servers. It is processed in memory during analysis and discarded after the report is generated.
- Local storage: Your most recent analysis result is saved in your browser's local extension storage so you can revisit the report. This data never leaves your device unless you initiate a new scan.
5. Third-Party Services
ReviewLenz uses the following third-party services to deliver analysis:
- OpenAI (GPT-4o) — processes review text to generate the structured analysis. OpenAI's data usage policies apply to this processing. Reviews are sent as API input and are not used by OpenAI to train models per their API terms.
- Railway — hosts our backend server infrastructure.
We do not share data with advertisers, data brokers, or analytics services.
6. Permissions Explained
- tabs: To detect when you're on a Trustpilot review page and activate the extension UI.
- storage: To save your analysis results locally and maintain your session identifier.
- scripting: To run the content script that extracts review data from Trustpilot pages you scan.
- windows: To open minimised browser windows for collecting review pages without interrupting your workflow.
- Host access to trustpilot.com: To navigate and read Trustpilot review pages during scanning.
- Host access to doreviews.site: To communicate with our analysis API server.
7. Your Choices and Control
- You choose when to scan — the extension never collects data without you clicking "Start Scanning".
- You can cancel any scan in progress.
- You can clear locally stored results by removing the extension or clearing extension storage.
- You can uninstall the extension at any time to stop all data collection.
8. Security
All communication between the extension and our server uses HTTPS encryption. Review data is transmitted securely and processed in isolated server environments. We follow industry-standard security practices for our infrastructure.
9. Children's Privacy
ReviewLenz is not intended for use by individuals under the age of 13. We do not knowingly collect data from children.
10. Changes to This Policy
We may update this privacy policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the extension after changes constitutes acceptance of the revised policy.
