## What is ContactTrim?

Duplicate contacts and blank cards piling up? ContactTrim cleans them safely. Every feature is free — there is no paywalled functionality.

Worried about bad merges or lost contacts? That is exactly what ContactTrim is built for:

• Automatic snapshots with one-tap rollback — before any merge or delete, every affected contact (photo included) is saved to a local snapshot. Restore the original state anytime.
• Field-by-field merge preview — see the diff first: phones and emails are unioned and deduplicated automatically; for conflicting fields like name or company, you pick which card's value wins. No all-or-nothing merges.
• Adjustable sensitivity — loose / standard / strict presets plus fine-grained threshold tuning; go strict if you fear false positives.
• Three problem types in one scan — exact duplicates, likely duplicates (country-code-aware phone matching, fuzzy name matching for both CJK and Western names), plus blank and incomplete cards.
• Unlimited merges, unlimited cleanup, unlimited snapshots and rollbacks.
• Duplicates across accounts (e.g. iCloud vs. work) are flagged but never auto-merged, so nothing gets lost.

About privacy:
• Scanning, matching, merging and snapshots all happen on your iPhone. Your contacts are never uploaded, analyzed, or shared with anyone.
• Contact notes are never read or modified (the notes entitlement is not requested).
• No tracking, and no "Allow Tracking" prompt.
• Only the banner at the bottom of the screen needs a connection, and ads never touch your contact data. Everything else works offline.

Prefer no banner? A one-time "Remove Ads" purchase is available in Settings. It only hides the bottom banner — it does not unlock anything, because every feature is already free.
