Privacy Policy
Last updated: September 2026
UnfollowLens does not store your uploaded file or analysis results on our servers.
1. Service Overview
UnfollowLens is a free web service that analyzes Instagram data files to find accounts that don't follow you back.
2. Data Processing
- Uploaded Files: Instagram ZIP files are never sent to a server. The file is processed entirely in your browser.
- Data Storage: Analysis results are only displayed in the user's browser and are not stored on our servers.
- Account Status Check: Only the Instagram usernames (public handles) of accounts that do not follow you back are sent to our server to check whether they are active, deleted, or private. Our server does not store these usernames; they are discarded once the request is processed. See section 4 for what Apify retains.
- Account Information: No registration or login is required.
3. Cookies and Tracking
- Language Settings: Your selected language preference is stored in your browser's localStorage.
- Google Analytics: We use Google Analytics 4 for visit statistics. It collects usage data such as page views and device/browser information via cookies; this data does not include your name or email. See the Google Privacy Policy for details.
- Google AdSense: This service uses Google AdSense to display advertisements. Google may use cookies to serve ads based on your interests. For more information, please see Google's Advertising Policies.
- Support Links: The site links to external support pages such as Buy Me a Coffee; once you leave this site, that service's privacy policy applies.
4. Third-party API Usage
Account status checks are performed through Apify, a third-party data provider, which looks up public Instagram profile information. During this process:
- We do not log into your Instagram account.
- We only check publicly accessible information.
- The only information passed along is the username of each account being checked; your uploaded file and your own account details are never shared.
- Profile images are fetched through our server for display; the server relays them without keeping a copy (your browser may cache them).
- Apify's handling of this data is governed by the Apify Privacy Policy.
- Apify keeps a record of each lookup (the usernames and results) for a limited period under its own retention policy.
5. Data Security
- All communications are encrypted via HTTPS.
- Uploaded files are never sent to a server and are processed entirely in your browser.
- No user data is permanently stored on our servers.
- Request IPs are processed only in memory for rate limiting and are never written to files or logs. Cloudflare, which hosts the site, processes requests under the Cloudflare Privacy Policy.
6. User Rights
No personal information remains on UnfollowLens servers, so there is nothing to request deletion of from us. Records held by Google, Apify, or Cloudflare are governed by their own policies and procedures.
7. Policy Changes
This privacy policy may be updated as the service changes. Changes will be posted on this page.
