GDPR isn't a checkbox - it's a posture. If you're moving off rexx HR because their AVV / DPA is opaque, KI BMS 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

rexx HR is a full HR suite (employee files, payroll integration, recruiting, onboarding, talent management) with German legal grounding and enterprise experience. KI BMS is only the recruiting module - but productive faster, KI pre-sort in the free tier, monthly cancellation. Need a real HR suite? Pick rexx. Want a dedicated ATS? Pick us. Common reality: rexx HR for files, KI BMS for the pipeline.

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. KI BMS 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 rexx HR sits on each of these is the rest of this page.

When to pick which

Pick KI BMS when

Recruiting is the bottleneck; the rest of HR is manageable with Excel + DATEV.
You want your ATS set up in an afternoon, not a quarter.
Small to mid team (8-100 employees), not controlled by procurement.

Pick rexx HR when

200+ employees, want employee files + onboarding + payroll integration in one tool.
Procurement + works council require a mature HR suite with enterprise experience.
Talent management + training should be connected to the ATS.
