Monica

Monica is a personal relationship manager, a contact book that remembers the context behind every person in your life. Each contact can hold details, notes, reminders, tags, a gift history and a timeline of interactions, and records can be imported from Google, Outlook, Apple or another Monica instance.

People use it to stay in touch with friends and family, to keep track of professional contacts and conversations, or to manage a shared household address book.

Hosting it yourself keeps that social map confidential, avoids paying per contact, and turns the whole history into a database you can copy and restore.
