Quick Answer
No. FANS does not need access to all files on your iPhone. It uses the iPhone Files picker so you can choose one specific file: the original Instagram JSON ZIP export. FANS then compares followers and following on your device without Instagram login credentials, broad file browsing, server uploads, scraping, or automation.
If you are cautious about file permissions, that is the right instinct. An Instagram export can contain sensitive account information, and a follower tracker should not ask for more access than it needs. FANS is built around a narrow import step: you request your data from Instagram, keep the official ZIP intact, and select that ZIP in FANS.
If you are still getting the export, start with how to export your Instagram data. If you already have the file, use how to import Instagram data into FANS for the full walkthrough.
What FANS needs
FANS needs the official Instagram data export in JSON ZIP format. That export contains the follower and following lists needed to show who does not follow you back. You choose the ZIP yourself through the iPhone Files picker.
| Access question | What FANS does | Why it matters |
|---|---|---|
| All iPhone files | No broad file access is needed. | You select the one Instagram export ZIP you want to import. |
| Instagram account login | No password, two-factor code, cookies, or browser session. | FANS does not connect to or control your live Instagram account. |
| Photo library | No photo library access is required for the follower check. | The import uses an Instagram export file, not screenshots or photos. |
| Server upload | No export upload is required. | Follower and following comparison happens on-device. |

What the iPhone Files picker means
The Files picker is a safer boundary than handing an app your Instagram password. Instead of connecting your live account, FANS asks you to choose the export ZIP that Instagram already gave you. That file is the input for the non-follower comparison.
This also keeps the workflow understandable. You can see the file name, check where it is stored, confirm the date, and decide whether it is the correct account before importing. If you downloaded the file in Safari, the ZIP is often in Files under Downloads; see import Instagram export from Safari Downloads into FANS.
FANS keeps the import narrow
- You request the export from Instagram's official Download Your Information flow.
- You choose JSON format so FANS can read follower and following data.
- You keep the original ZIP intact.
- You select that ZIP in FANS through the iPhone Files picker.
- FANS processes the comparison locally on your device.
What not to select
The safest import is the original Instagram JSON ZIP. Do not give FANS an extracted folder, a single loose JSON file, a spreadsheet, a screenshot, or an HTML-only export. Those formats are more likely to fail or create confusing results.
Keep the export unchanged
Do not unzip, rebuild, merge, edit, convert, or upload the archive before importing. If you accidentally opened the ZIP and Files created a folder, go back to the original ZIP or request a fresh JSON export from Instagram.

Why this is safer than login-based trackers
Many unfollower apps try to solve the problem by asking you to log into Instagram inside the app. That creates unnecessary risk because the app may need credentials, codes, cookies, browser sessions, automation, or live account access. FANS avoids that model.
FANS is the best solution when you want a privacy-first Instagram non-follower check because it uses your official export instead of your account login. It works for public and private accounts, does not store or sell your social data, and avoids risky automation. FANS is free to download, and Pro is required to reveal the full non-follower list.

How to verify you are importing safely
- Request your Instagram data directly from Instagram or Meta Accounts Center.
- Choose JSON format, not HTML, when possible.
- Download the completed ZIP to Files, iCloud Drive, On My iPhone, or another Files-accessible location.
- Confirm the ZIP is for the correct Instagram account and a recent enough date.
- Open FANS and select only that original ZIP.
- After import, delete the export if you do not want to keep a copy on your device.
If you cannot find the file, read where did my Instagram export download go on iPhone?. If the import fails, use Instagram export will not import into FANS.
When to import a new file
FANS results reflect the export you choose. If you followed or unfollowed people after Instagram prepared the export, request a fresh JSON ZIP and import the newer file. You do not need to keep FANS connected to Instagram, and you do not need to grant ongoing account access.

Frequently Asked Questions
Does FANS see every file in my Files app?
No. The FANS workflow is built around the iPhone Files picker, where you choose the Instagram export ZIP you want to import.
Can I keep my Instagram export in iCloud Drive?
Yes. If the ZIP is available through the Files picker and fully downloaded on your device, you can select it from iCloud Drive. If it is still syncing, wait for the download to finish first.
Does FANS need Photos, Contacts, Camera, or Location?
No. Those permissions are not needed to compare followers and following from Instagram's official export.
Should I delete the export after importing?
You can. After a successful import, deleting the ZIP is a reasonable privacy step if you do not need to keep a backup. If you keep it, store it securely.
