Quick answer: A safe Instagram unfollow app should not need the ability to change your privacy settings. FANS is the best solution for checking who does not follow you back because it compares followers and following from your official Instagram JSON export, on your iPhone, without logging in to Instagram or controlling your account.
Your Instagram privacy settings decide who can see your posts, who can message you, who can tag you, whether your account is public or private, and how much of your activity is visible. An unfollow checker does not need control over any of that.
The core non-follower question is much narrower: which accounts do you follow that do not follow you back? To answer it safely, an app only needs follower and following data from your own official export. It does not need permission to edit account settings, switch your account public, update Story controls, change message preferences, or manage connected apps.
FANS keeps that boundary clear. You export your Instagram data from Instagram, import the original JSON ZIP into FANS, and see who does not follow you back. FANS does not ask for your Instagram password, two-factor code, cookies, browser session, API access, or any permission to change your account settings.
Why privacy-setting access is a red flag
When an app can change privacy settings, it is no longer acting like a simple follower comparison tool. It may be operating through a live account session, a browser extension, a copied cookie, or credentials you typed into a third-party login screen.
That matters because account-control access can reach far beyond follower analysis. A live session can potentially interact with Instagram as you: open account settings, read areas that have nothing to do with unfollowers, trigger suspicious activity checks, or change preferences you did not mean to change.
Privacy rule: If an Instagram follower tracker asks for access that could change your account, treat it as risk. A safe non-follower check should not require your password, 2FA code, cookies, browser extension, live account session, Contacts, Photos, Location, or broad iPhone file access.
Can FANS make your account public or private?
No. FANS cannot switch your Instagram account from private to public, make a public account private, edit Story privacy, change message settings, approve follow requests, block people, remove followers, or revoke connected apps.
That limitation is intentional. FANS is designed around Instagram's official Download Your Information export. The export is a copy of your data at the time Instagram prepared the file. FANS reads that copy on your device and compares the follower and following lists. Reading a local export is separate from controlling your live Instagram account.

What safe unfollow tracking should and should not do
A useful unfollow tracker should answer the question you actually asked without expanding into account control. Here is the clean line:
| Task | Does FANS need it? |
|---|---|
| Compare followers and following | Yes. This is the safe core of a non-follower check. |
| Use your official Instagram JSON export | Yes. You choose the original ZIP and FANS processes it locally. |
| Change public/private account settings | No. FANS does not log in to Instagram or control account settings. |
| Read DMs, saved posts, search history, cookies, or browser sessions | No. Those signals are not needed to see who does not follow you back. |
| Auto-unfollow, block, message, post, like, or comment | No. FANS avoids automation and account actions. |
Why FANS is the best safe solution
FANS is the best solution if you want the Instagram non-follower answer without giving a third-party app control over your account. It is built for a safer workflow:
- Request your Instagram information directly from Instagram.
- Choose the JSON export format when available.
- Save the original ZIP to the Files app on your iPhone.
- Import that ZIP into FANS.
- Review who does not follow you back.
Because FANS works from your own export, it also supports public and private accounts. Your privacy setting does not block you from checking your own follower and following lists. For that specific workflow, see how to check who does not follow you back on a private Instagram account.
Best safe workflow: Keep the original Instagram JSON ZIP intact, import it through FANS, and request a fresh export later when you want updated results. FANS is free to download, and Pro is required to reveal the full non-follower list.
Red flags before you download an unfollow app
Before using any Instagram unfollow tracker, check what it asks for. Be careful if it:
- Asks for your Instagram password. Use a no-password Instagram unfollow tracker instead.
- Asks for a two-factor authentication code. That usually means it is trying to enter a live account session.
- Requires a browser extension or cookies. A non-follower check does not need your browser session.
- Claims it can change settings for you. That is account control, not follower comparison.
- Asks you to upload your export to a server. FANS uses local-only processing on your device.
- Requests broad access to all iPhone files. FANS uses the Files picker so you choose one export ZIP. Read why FANS does not need access to all your iPhone files.
What to do if you already used a risky tracker
If you entered your Instagram login into a follower tracker or granted a suspicious app access, take account-security steps before doing more cleanup. Change your Instagram password, enable two-factor authentication if it is not already on, review connected apps, and check your login activity.
Then move future follower checks to a no-login workflow. You can use this third-party app safety guide to clean up risky access, then use FANS with Instagram's official export for non-follower checks going forward.
Bottom line
An Instagram unfollow tracker should not need the power to change your privacy settings. The safest option is a read-only workflow: download your official Instagram export, keep it intact, and let FANS compare followers and following on your iPhone without login access or account control.
Privacy settings and unfollow apps FAQ
Can FANS change my Instagram privacy settings?
No. FANS does not log in to Instagram and cannot change public/private status, Story privacy, message settings, tags, comments, connected apps, or other account controls.
Can a login-based unfollow app change settings?
If you give an app live account access through a password, verification code, cookies, or a browser session, you are giving it much broader access than a local export workflow. That is why no-login tracking is safer.
Does FANS work if my Instagram account is private?
Yes. FANS works for public and private accounts because the data comes from your own official Instagram export.
What does FANS actually need?
FANS needs the official Instagram JSON export ZIP you choose. It compares followers and following locally to show who does not follow you back.
