When two contact records likely belong to the same person, Alps flags it for you instead of leaving you to spot it manually. You decide whether to merge them or dismiss the suggestion.
Spotting a possible duplicate
When Alps suspects two contacts are the same person, the newer contact's profile shows a possible duplicate banner naming the suggested match. You can open that contact to compare the two before deciding what to do.
Merging two contacts
If the suggested match really is the same person, merge them from the duplicate banner. One contact becomes the primary record and absorbs the other. Here is exactly what happens:
Conversations, WhatsApp threads, and other identities from both contacts are combined onto the primary contact.
Notes from both contacts are kept, not overwritten.
Custom property values from the duplicate take priority if the same property was filled in differently on both records.
Every conversation that pointed to the old contact is re-pointed to the primary one, so nothing gets orphaned.
The duplicate record is deleted once the merge completes. This can't be undone, so it's worth a quick check before confirming.
Dismissing a suggestion
Not every flagged pair is actually the same person. If Alps got it wrong, you can dismiss the suggestion directly from the banner, which clears the flag without changing either contact.
