GDPR isn't a checkbox - it's a posture. If you're moving off Cloze because their AVV / DPA is opaque, Contact Book is what a clean alternative looks like: subprocessor list of two (Stripe + mail relay), self-serve export + delete from account settings, and a standard German GDPR DPA on request when your procurement team needs one.

At a glance

Cloze ingests your email + calendar + social and uses AI to surface contacts you should reach out to. Contact Book is the opposite - it expects you to log meaningful interactions deliberately, and trades AI surfacing for a calmer, more private system. If you want a relationship intelligence engine that watches your inbox, Cloze is the obvious pick. If you want a personal CRM that does not read your email, that's exactly what we are.

GDPR posture

GDPR is a posture, not a checkbox

Three things matter under GDPR for a tool like this: (1) lawful basis for processing, (2) data subject rights (export, delete, port), and (3) the auftragsverarbeitungs­vertrag / DPA chain. Contact Book treats them as engineering invariants, not legal optics. Lawful basis is the contract you sign with us. Subject rights are self-serve from your account settings - no support ticket required. The subprocessor list has two entries (Stripe + mail relay). A standard German GDPR DPA is available on request from /sales whenever your procurement team needs one - we don't charge for it and don't gate it behind a plan tier. Where Cloze sits on each of these is the rest of this page.

Hosted in Germany matters; you don't want US-headquartered infrastructure for your inbox-adjacent data.

Pick Cloze when
