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 Google Contacts 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.
Google Contacts is excellent at what it does: keeping a phone-shaped address book in sync across your devices. Contact Book is built for the next layer up - logging conversations, gifts, life events, and follow-ups so the relationships you care about don't quietly drift apart. If you only need names + numbers on your phone, stick with Google. If you find yourself opening a contact card and asking what did we last talk about, you'll outgrow Google Contacts the same week you try 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 Google Contacts sits on each of these is the rest of this page.
GDPR questions
