Please include the following information when you write to us — it speeds up handling a lot:

1. Your iOS version (for example iOS 17.5)
2. Your device model (for example iPhone 16 Pro)
3. The app version number
4. A screenshot or a description of the steps that reproduce the problem
5. Expected behavior vs. actual behavior

• Pricing: One-time purchase $0.99 — pay once, unlimited renames forever
• Request a refund: reportaproblem.apple.com
• Restore purchases: open the app → “Unlock” button at the top → “Restore Purchases”

Apple handles the entire charge. The app never touches your payment details. Prices are as currently shown in the App Store. A one-time purchase is a single payment — it never renews on its own and is never charged again.

BatchRenamer runs entirely on your device and does not collect any personal information. See the full details in our Privacy Policy.

Q: How do I undo a rename?
After you run a rename once from the main screen, an “Undo this rename” button appears below it, and you can roll the whole operation back immediately.

Q: Why does the app say the folder has no permission when I open it?
Please use the “Choose Folder” button to authorize a folder through the Files app. The app can only access folders you have explicitly authorized.

Q: I have used up my free renames.
You get 3 free renames to try first. After that, a one-time purchase of $0.99 gives you unlimited renames forever — pay once, it never renews on its own.
