What is ContactAttic?

ContactAttic is a local desktop app that merges your contacts from every old phone, account and export into a single, clean, de-duplicated address book that lives entirely on your own machine.

It imports vCard files (2.1, 3.0 and 4.0) and merges duplicate people together — the same person split across five cards with three phone numbers becomes one clean entry. It reads from compressed and nested archives so nothing is left behind, and never silently drops a contact that exists in only one source.

Deliberately not cloud, not AI, and not a subscription. Your contacts never leave your computer, there is no account and nothing is uploaded. It is desktop software you buy once and own, and all minor updates are free.

ContactAttic is one of the Attic apps, which apply the same approach to email, photos, documents and chats.

Platforms: Windows and Linux (macOS coming). One-time purchase.
