Quick Answer
Deleting or reinstalling FANS does not change anything inside your Instagram account. FANS does not connect to Instagram, control your account, or store your social graph on a server. If you delete the app, plan to reimport the original Instagram JSON ZIP or request a fresh export when you want to check non-followers again.
This is a practical privacy question. If an app says your Instagram data stays local, you should know what happens when you remove the app, offload it, reinstall it, or move to a new phone.
FANS is the best solution for checking who does not follow you back because it keeps the workflow simple: export your data from Instagram, import the official JSON ZIP into FANS, and review the result on your device without Instagram login access. That same model makes deletion and reinstalling easier to understand.
What deleting FANS does and does not do
Deleting FANS removes the app from your iPhone. It does not delete your Instagram account, unfollow anyone, remove followers, erase posts, change privacy settings, revoke Instagram sessions, or affect anything stored by Instagram.
| Action | What happens | What to do next |
|---|---|---|
| Delete FANS | The app is removed from your iPhone. Your Instagram account is unchanged. | Reinstall later and import an official JSON ZIP if you want results again. |
| Offload FANS | iOS may remove the app while keeping some app documents depending on device settings. | If anything looks missing after reinstalling, import the ZIP again. |
| Delete an Instagram export ZIP | Your local copy of the export is removed from Files or Downloads. | Request a fresh export from Instagram if you need another import. |
| Delete Instagram | This is separate from FANS and affects the Instagram app or account, depending on what you choose in Instagram. | Export your data first if you want a non-follower snapshot before leaving. |

Will reinstalling FANS restore old results?
The safest assumption is that a reinstall needs a new import. FANS works from the export file you choose, not from a hidden live connection to Instagram. If your previous result is not present after reinstalling, that is not a blocker. Import the original Instagram JSON ZIP again, or request a fresh export for current results.
The clean reinstall workflow
- Reinstall FANS from the App Store.
- Find your original Instagram JSON ZIP in Files, iCloud Drive, Downloads, or another Files-accessible location.
- Open FANS and import the original ZIP.
- If the ZIP is old, request a fresh official export from Instagram instead.
- Review the non-follower list in FANS without logging into Instagram inside the app.

Should you keep the export before deleting the app?
It depends on whether you want to preserve that snapshot. An Instagram export is a point-in-time file. Keeping it lets you reimport the same historical snapshot later. Requesting a fresh export gives you a newer answer.
- Keep one secure copy if you want to recheck the same date or compare old and new results manually.
- Delete old copies if you do not need them and want less sensitive data sitting in Files, Downloads, Mail, or cloud storage.
- Request a fresh export when you want the current list of who does not follow you back.

Why FANS is safer after reinstalling than login-based trackers
Some tracker apps make reinstalling feel risky because they depend on a live account connection. They may ask you to log in again, paste a verification code, reconnect a browser session, or grant new permissions. That is not the FANS model.
FANS uses Instagram's official Download Your Information export. It does not need your Instagram password, two-factor code, cookies, browser session, Meta account link, API key, VPN, proxy, scraping access, or automation permissions. Reinstalling the app does not create a new Instagram security event because FANS is not logging into Instagram as you.

What if you switched phones?
If you deleted FANS because you switched to a new iPhone, the same rule applies: import a valid Instagram JSON ZIP again. You can move the original export through iCloud Drive, AirDrop, or another Files-accessible location, or you can request a fresh export from Instagram.
The dedicated new-device guide is Use FANS After Switching to a New iPhone. If your export is in iCloud Drive, read Import Instagram Export From iCloud Drive Into FANS.
Do not use reinstalling as a reason to share your login
If another tracker asks for your Instagram username and password after you reinstall it, stop. A simple non-follower check should not require live account access. Use the official export and import it into FANS instead.
How to refresh after reinstalling
If you want updated results after reinstalling FANS, request a new Instagram export. Every export is a snapshot. A ZIP from last month cannot include new follows, unfollows, follow-backs, username changes, or account removals that happened after Instagram prepared it.
- Open Instagram or Meta Accounts Center and request your data export.
- Choose JSON format when Instagram gives a format option.
- Save the original ZIP to Files, iCloud Drive, or On My iPhone.
- Open FANS and import the ZIP without unzipping or rebuilding it.
- Use the new result as your current non-follower list.

Does deleting FANS delete my Instagram account?
No. Deleting FANS only removes the iPhone app. Your Instagram account, posts, followers, following list, messages, and settings remain controlled by Instagram.
Can I reinstall FANS and use the same export?
Yes, if you still have the original Instagram JSON ZIP and want the same snapshot. If you want current results, request a fresh export before importing.
Does FANS need my Instagram password after reinstalling?
No. FANS never asks for your Instagram password, verification code, cookies, browser session, or live account access. Reinstalling does not change that workflow.
Should I delete old Instagram exports too?
