ContactTrim: Merge Contacts

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.
