He followed someone.You'll know who.

Yes. Type the username, done. No Instagram login needed on your end.

The web app does — any browser, iOS or Android. The Chrome extension is desktop-only (Chrome, Edge, Brave, Opera) because mobile browsers don't support extensions.

If you follow them on Instagram, yes. The Chrome extension reads private accounts through your own logged-in session — nothing you couldn't already see by hand.

No — and honestly, neither can any other tool. If you don't follow them, Instagram doesn't show you their data, period. The Chrome extension works only on private accounts you already follow, because it uses your own session.

No. No profile visits are logged on their end, no follow requests are sent, and public stories can be viewed without appearing in the viewers list. You're reading the same public page anyone else can — just dated and saved.

No. The web app reads public data the same way any browser does — no bots, no fake accounts, no API abuse. The extension reads through your own session, with the same profile you already use daily.

Yes, for public accounts — anything a person can see by visiting a profile is public-record data; we just log it systematically. For private accounts, the Chrome extension only reads what your own logged-in Instagram session is already allowed to see. No scraping around permissions, no backdoors.

Never. We don't ask, store, or touch it. Not even a little.

Snapshots. Comparisons over time. No hacking, no secret access — just cleaner data.

Daily, automatically, for every account you're tracking. The live timeline updates as new changes are detected, and you get a weekly email summary every Monday with what shifted.

Type your username into Loyalty Lens. We snapshot your followers daily, and every Monday you get an email listing everyone who left that week, with the date. Exportable to CSV if you want receipts.

Web app = fast check, any device, public accounts. Extension = deeper history, timestamps, exports, private accounts you follow.

Yes. CSV export is there for when you need more than a screenshot from memory.

Yes to start — 500 free credits, no card, no trial timer. One check costs one credit, so you can watch a couple of accounts for a long time before you ever think about topping up.
