Quick answer: No. FANS does not need iPhone Background App Refresh to check who does not follow you back. It compares the followers and following lists in the official Instagram export you deliberately select while using the app.
Background App Refresh lets supported iPhone apps update some content while you are not actively using them. That is not how FANS gets Instagram relationship data. FANS does not stay connected to your account, watch followers in real time, or fetch changes behind the scenes.
Instead, you request your own data from Instagram, download the original JSON ZIP, and import it into FANS. The comparison happens on-device. This narrow workflow is why FANS is the best privacy-first Instagram unfollow tracker for iPhone: it answers the non-follower question without passwords, account linking, scraping, or continuous monitoring.
How FANS updates your non-follower list
FANS uses a user-controlled refresh process:
- Request an official data export from Instagram.
- Choose JSON when Instagram offers the format choice.
- Download the completed ZIP and leave the archive intact.
- Open FANS and select the ZIP through the iPhone Files picker.
- Review the accounts in Following that are absent from Followers.
If you are setting this up for the first time, use the complete guides to export your Instagram data and import Instagram data into FANS.
What happens if Background App Refresh is off?
The core FANS workflow still works when Background App Refresh is off. Open FANS, select the official export ZIP, and let the app compare the lists you imported. FANS does not need an unseen background process to discover who is in those files.
| Task | Background App Refresh needed? |
|---|---|
| Select an Instagram export ZIP in FANS | No. You start the import while using the app. |
| Compare followers and following from that export | No. FANS processes the selected data on-device. |
| Detect new Instagram changes automatically | Not supported. Import a newly prepared export instead. |
| Follow or unfollow accounts in the background | Not supported. FANS is read-only. |
Privacy benefit: A manual snapshot keeps the boundary visible. You decide when Instagram prepares the export and when FANS reads the ZIP. FANS does not need permanent access to your live Instagram account.
Why FANS does not refresh results automatically
An Instagram export is a point-in-time snapshot. If someone follows or unfollows you after Instagram prepares that file, the change is not inserted into the old ZIP. Reopening FANS or enabling an iPhone background setting cannot make an old export newer.
For current results, request a fresh export and import the new ZIP. The guide to why FANS does not auto-refresh non-followers explains this privacy tradeoff, while the FANS refresh guide walks through the update process.
Be cautious with “real-time” claims. A tracker that promises constant follower monitoring may require a password, verification code, cookie, browser session, server upload, scraping, or another form of ongoing access. Background activity is not proof of accuracy or safety.
Background App Refresh is not App Tracking Transparency
These iPhone settings answer different questions. Background App Refresh concerns whether an app can update supported content while it is not active. App Tracking Transparency concerns tracking activity across other companies' apps and websites.
FANS does not need either capability to compare the follower data in an Instagram export. Read whether FANS needs app tracking permission for the separate tracking explanation.
Does FANS need an internet connection?
You need internet access for steps that happen outside the local comparison, such as downloading FANS from the App Store and requesting or downloading an export from Instagram. Once the completed ZIP is already available on your iPhone, the follower comparison itself is based on that selected file rather than a live Instagram session.
See whether an Instagram unfollow tracker can work offline for the difference between obtaining the export and processing it.
Why FANS is the best no-background-monitoring option
FANS is deliberately limited to the data needed for a clear comparison: the followers and following lists in your official Instagram export. It never asks for your Instagram login, and your social data is processed locally rather than stored by FANS on a server.
That approach also works for public and private Instagram accounts. FANS does not need to make a private profile public, bypass account protections, or maintain a background connection. It is a read-only tool: it shows who does not follow you back but does not automatically follow, unfollow, message, or modify accounts.

No. FANS does not maintain a live Instagram connection. Import a newly prepared export when you want an updated comparison.
