FollowSight privacy policy

Last updated: 10 November 2026

FollowSight is a browser extension that shows who doesn't follow you back on Instagram, along with your fans, mutuals, new followers, unfollowers and blocked accounts, and lets you follow, unfollow, block or unblock from those lists. This policy explains what the extension touches and where that information goes.

The short version

• FollowSight has no server. It does not collect, sell or share your data, and the developer never receives anything unless you choose to send it yourself.
• It never asks for your Instagram password. It works inside the instagram.com tab you are already logged in to.
• Your lists and their history are saved in your browser only.
• No analytics, advertising or tracking code is included, in the extension or on this website.

Requests to Instagram

FollowSight works only while an instagram.com tab is open and logged in. When you press Scan, it runs small scripts inside that tab that call the same web addresses Instagram's own website uses to show your followers and following lists, the follow status of those accounts, your blocked accounts, and your account's name and picture. Because the requests run in your tab, your browser sends them with your existing Instagram session, and they go directly from your browser to Instagram. FollowSight does not read or store your password or cookies. It reads page values Instagram needs for a request (such as its security tokens) at the moment of the request and does not keep them.

Follow, unfollow, block and unblock are sent to Instagram only when you click that button for one account. FollowSight does not perform actions on its own, in bulk, or on a schedule.

FollowSight does not read your messages, posts, stories, comments, likes or saved items.

Profile pictures

Profile pictures are loaded from Instagram's image servers (cdninstagram.com and fbcdn.net), the same places Instagram loads them from, without sending your Instagram cookies.

Information stored on your device

For each Instagram account you scan with, FollowSight saves:

• The latest followers and following lists: username, display name, account id, picture address, and whether the account is verified or private.
• The changes found between scans: new followers, unfollowers, and accounts that disappeared from both lists.
• Your Ignored list, the Blocked list as last loaded, your own name and picture address, and the number of new unfollowers you haven't looked at yet (for the toolbar badge).

It also saves your view choices (sort and filters), the colours it copies from Instagram's light or dark theme, and timers that keep it from repeating a request Instagram recently refused.

This is kept in the browser's extension storage on your device only. Clear saved data in the panel deletes the saved lists, changes, ignored and blocked lists and profile details for the account you are viewing. Uninstalling FollowSight removes everything.

Copy debug info and exports

Copy debug info copies a short report to your clipboard: the extension version, your browser's name and version, when you last scanned, whether each kind of request worked, and how many accounts each list returned. It contains no usernames, account ids or tokens. It is only shared if you paste it somewhere yourself.

Copy usernames and Export CSV save the list you are looking at to your clipboard or to a file on your device. Nothing is uploaded.

Links that open other sites

Open profile opens the account on instagram.com, and Message opens an ig.me link in your browser. Anything you do there is covered by Instagram's own privacy policy.

Permissions

• scripting: runs FollowSight's requests inside your logged-in instagram.com tab.
• storage and unlimitedStorage: save your lists and their history on your device. Large accounts can have thousands of followers, and a history of changes, which can go past the browser's default storage limit.
• sidePanel: shows FollowSight in the browser's side panel, so it stays open with your lists while you use Instagram.
• Access to instagram.com: needed to run those requests in your Instagram tab.
• Access to cdninstagram.com and fbcdn.net: loads profile pictures from Instagram's image servers.

Changes

If this policy changes, for example if a paid version that checks a licence is added, the updated version will be posted at this address with a new date before that version is released.
