Frequently asked questions
Does the app delete anything automatically?
No. Photos deletion requires your selection and the iOS confirmation. Contacts change only after a separate reviewed merge confirmation; Files checks remain read-only.
Do my photos leave my iPhone?
No. Photo, video, screenshot text, and similarity analysis runs on your iPhone and is not sent to our server.
Why does the app need Photos access?
Access is required to inspect the library you select, build local comparisons, and request a deletion only after your review.
Can I use Limited Photos access?
Yes. The app remains usable with the items you select, and iOS lets you change the limited selection later.
What is Local Scan?
Local Scan analyzes eligible items already available on the device and avoids requesting iCloud media downloads.
What is Complete Scan?
After your confirmation, Apple Photos may download eligible iCloud items directly to the iPhone for broader analysis.
Can I recover deleted photos?
Photos normally places deleted items in Recently Deleted. Recovery timing and behavior are managed by Apple Photos.
What does Reset analysis do?
It clears app-owned local analysis state. It does not delete any photo or video from your Photos library.
How do I remove an item from deletion?
Tap its selected control again. The item is removed from the deletion list immediately.
Does the app require payment?
The app is a one-time paid App Store download. The price is USD 5.00 in the United States and VND 149,000 in Vietnam; the App Store displays your applicable local price. All shipping features are included, with no subscription or additional in-app purchase.
Can I merge duplicate contacts?
Yes. Scan accessible contacts and review a group. Use Quick Merge · Preview to select the group and open a proposed result directly, or Review & Merge to choose at least two cards manually with nothing preselected. Quick Merge proposes primary details from the scanned name, phone, email and organization fields; it does not prove that the cards belong to one person. In the preview, change selected contacts to exclude another person, change primary details or change the destination account. Inspect the proposed fields before confirming. Preparing or cancelling a preview does not change contacts or create a backup. Verified contacts can be merged across accounts. Select the destination account/address book and review where the result will be saved and which source cards will be deleted. One selected source already in that destination is updated, preferring a primary source; otherwise a new contact is created there and all selected sources are deleted. Other primary sources are also deleted. Only groups in the destination address book can be retained. Unverified sources, unavailable accounts or provider restrictions can prevent completion; scan again before retrying if a save fails. Shared phone numbers or emails are potential matches, not proof of identity. Confirmed changes may sync through your Contacts provider.
Are contact Notes copied?
No. The app cannot read or back up the restricted Notes field on deleted cards. Save important Notes separately in Contacts before merging. Only Notes on the actual retained destination source are untouched; other primary sources may be deleted when consolidating accounts. This limit is disclosed before confirmation.
How do Merge Backups work?
A protected local vCard of readable fields from every selected source card, including linked cards, is required before a merge writes changes. Export or delete it in Merge Backups. Recovery is manual import in Contacts and may create duplicates; it does not automatically restore account locations, groups or undo a merge. Copies are excluded from OS backup, survive failed merge attempts, and are removed when you delete them or uninstall the app.
Does the app scan all files on my iPhone?
No. Duplicate Files reads only the folder chosen through Files. A provider may download content for comparison or preview. It does not modify or delete files.
