Privacy focused people management and search

Contacts are scattered all over your apps, often have a large overlap, and aren't necessarily filled in with the most amount of information you'd like. When every app requests access to your contacts, it doesn't really feel like you own your network.

And even when you meticulously update your private Apple contacts, there's no good way to keep building the relationship or continuously updating their important details.

Contrack solves all of these by being an all-in-one, self-hosted contact management app that a follows a simple 4 step process:

Import → Dedupe → Enrich → Track

	Import Everyone, from everywhere. Drop in your contacts from Apple, Google, LinkedIn or Facebook. Connect your calendar or inbox, and past conversations and meetings appear right on each person's timeline.
	Dedupe One person. One clean story. The same friend from three address books becomes a single profile. Contrack merges the obvious matches automatically and lets you review the rest side by side, with a 90-day undo if you ever change your mind.
	Enrich All the context you never had time to type. Paste a quick note like "Met at Sarah's wedding, loves natural wine, kids are Leo and Maya, catch up every quarter" or "Partner at Sequoia, follow up next Tuesday on seed round", and Contrack turns it into a complete profile with dates, tags, and reminders. Or let web research fill in roles and links with cited sources.
	Track Never let someone important drift away. Write a note in plain language and "next Tuesday" becomes a reminder automatically. Set how often you want to stay in touch, and each morning Contrack gently shows who is due and whose birthday or milestone is coming up.

Multiple profiles, one home Run one Contrack for your family or team. Invite someone with a link or create their profile in seconds. Every person gets their own private address book, notes, and reminders.

Verified backups Your history is irreplaceable. Take a complete, integrity-checked snapshot of your address book in one click, or let Contrack back itself up automatically on your schedule.

Works with your AI assistant Connect Claude, ChatGPT, or Cursor in one click so your favorite assistant can look up context and log notes for you, with read-only access whenever you prefer.

Right in your pocket Add Contrack to your phone's home screen. Before you walk into coffee or a meeting, every note and detail is one tap away.

And everything else you expect: rich notes with file & image attachments, @mentions that link people together, custom dates and anniversaries, lists and tags, passkey sign-in, a 90-day trash with undo, open exports anytime, and warm light and dark themes.

Privacy

Privacy isn't a setting. It's the foundation. Contrack lives on your own computer or home server. Your relationships aren't training anyone's model, sitting on a rented cloud, or locked behind a monthly subscription. Search happens right on your device.

Share one home server with your family or team while keeping everyone's address book completely private to them. And when you want AI to research a contact or turn a quick note into a rich profile, you bring the model you trust, or use none at all.
