Drop in one WhatsApp chat to see who carries it and when you last really talked. Set a pace for the people you want to keep close, get one quiet morning nudge when someone is due, reach out, and tap We spoke. We tell you plainly what we keep on our servers, and it is yours to export or delete at any time.

Bring in a WhatsApp chat you already have. Arcane reads the rhythm between you, helps you set a pace that fits, nudges you in the morning when someone is due, and keeps a private file for each person — alongside a family tree, a one-link birthday Ask, and five research-grade personality tests.
Drop in one WhatsApp export and Arcane reads the rhythm between you — not a scorecard, just the give-and-take you can't feel from the inside.
Keep the things you actually want to remember about the people in your life, set the pace you want to keep with each of them, and gather what's missing without chasing.
When someone slips past the pace you set, Arcane sends at most one quiet morning notification and gives you a starting point from their file.
Not a quiz with a cute label at the end. Arcane runs the actual instruments researchers use, with their published scoring and published norms — no invented types, and no verdicts.
When you save to your Arc, what it works out is kept on our servers so it reaches your other devices — we can read that copy, it is not encrypted yet, and nothing about it is hidden from you.
When you try a chat before signing up, it stays in this browser until you save. Once you save, your Arc — including saved chats (with the other person's messages), your notes, and your diary — is stored readable on our servers; we can read it, and it is not encrypted yet.
Saved chats include the other person's messages, which are never used to contact them or train models. Ask answers are held on our servers until the Ask's deletion date (30 days), and kept facts copy to that person's file. A shared family tree is visible to relatives you invite.
Export a full, portable copy any time — or delete a chat, a person, or your whole Arc in one tap. Deleting wipes the copy on our servers as well as the one in your browser, with nothing kept afterwards.
Everything above is the free Arcane. Mind+ is the optional layer we're building next — a model that reads your Arc and thinks with you, opt-in, and only ever with what you choose to share.
