Contact Book: the EU alternative to Cardhop
Same job, hosted in the EU. Contact Book runs in Germany under German law - your data stays in EU jurisdiction end to end.
If your reason for moving off Cardhop is data sovereignty, the comparison gets simpler. Contact Book is hosted in Germany on infrastructure we operate ourselves - no US-headquartered company in the request path. The CLOUD Act does not reach what physically lives here.
At a glance
Cardhop (from the Fantastical team) is a polished replacement for the stock Contacts app - fast search, natural-language entry, dialing and emailing in a tap, all reading your existing Apple / Google contacts. It's an address book done right. Contact Book is a different category: a relationship memory with cadence reminders, conversation logs, life events, gifts, and a family graph. Pick Cardhop if you want your existing contacts to feel great to use; pick us if you want to track the relationship, not just the phone number.
EU jurisdiction
What 'EU-hosted' actually means here, end to end
Contact Book runs on dedicated machines we operate ourselves, physically located in Germany. There is no US-headquartered subprocessor in the request path - the data plane (your records, your files, your audit log) lives entirely in EU jurisdiction. Two third parties exist outside that boundary: Stripe (payment information only, under the EU-US Data Privacy Framework) and the mail relay for transactional email. Neither sees your records. Cardhop's setup is the variable - if their primary infra is US-based, the CLOUD Act applies regardless of what their privacy page claims.
