Plain-language privacy notice, standard German GDPR DPA available on request, self-serve export + delete.

GDPR isn't a checkbox - it's a posture. If you're moving off Dex 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.
Dex is sharply focused on "don't lose touch" - it adds reminders + activity tracking on top of LinkedIn-style integrations. Contact Book does that too, and adds gifts, life events, pets, family relationships, and a journal. If keep-in-touch reminders are 80% of what you want, Dex is excellent. If you also remember birthdays, family details, gift histories, and want all of it in one place, you're more at home with us.
GDPR posture
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 Dex sits on each of these is the rest of this page.
GDPR questions
