ContactTrim: Merge Contacts

Streamline daily tracking and management with ContactTrim 連絡先の重複整理. Core features work offline, no account required.

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.
