In their own words
Contact Book
Contact Book is a personal CRM for capturing contact details, logging interactions and keeping track of gifts, life events and follow-ups. Profiles can hold emails, phones, companies, addresses, birthdays, social links, food preferences, allergies and how you met someone. A shared screen brings together profiles, a relationship graph, a timeline, life events, gifts, follow-ups and a journal. Users can import and export information, export everything or delete an account through self-service settings. The service is available on the web and offers HTTP API, CLI and MCP access to the same data and access rules. The operator says its application servers and database are hosted in Germany. Public endpoints use TLS 1.3, database disks are encrypted at rest, and backups are encrypted before leaving the primary host. Daily database snapshots are retained for 30 days, stored in another physical location, and restore tests are performed quarterly. The operator says it does not sell user data or share it with advertisers. Contact Book has a free plan; Standard costs €10 per month or €100 per year. Email and calendar sync are not offered.
