Is ListDiff safe?
Last updated: 2026-07-27
Short answer: yes, for normal list-comparison use. ListDiff at listdiff.org is designed so your list contents stay in the browser during compare.
What stays local
- Paste boxes, file imports, and compare results are processed in your browser session.
- You do not need an account to run a comparison.
- You can clear the page anytime with Clear all or by closing the tab.
What ListDiff does not do
- It does not log into Instagram, CRM, or other third-party accounts.
- It does not scrape platforms for you—you bring your own exports or pasted text.
- It is not a malware scanner; treat downloaded export files the same way you treat any file from your own accounts.
Analytics note
The site may use privacy-oriented analytics (for example page views) that do not need your list contents. Product privacy details are in Privacy.
