Signed before arrival, not scribbled at the desk
When a guest checks in online, they complete their registration details and sign them digitally before they ever reach your site. Nothing is re-typed by a receptionist and nothing waits on a paper form being legible.
Self / online check-in is an add-on, included from the Professional plan upward. Because the registration is already signed when the guest arrives, the queue at reception is shorter and the arrival is a hand-over, not a form-filling session.
In Germany: the municipal Meldeschein, in your municipality’s format
For Swiss sites, the registration is produced as the municipal Meldeschein in the exact format your municipality expects, and it is signed digitally at self-check-in.
The same check-in data is what Grondia compiles your guest-night statistics overnight statistics from, and what drives per-commune visitor tax — Kurtaxe by guest type, with exemptions and caps — so one signed registration feeds the reports instead of being re-entered three times.
One record, retained exactly as long as required
Every guest is one profile with one registration record, not a stack of loose forms in a drawer. Retention is enforced by the platform: records are kept for the required period and then securely deleted, rather than lingering indefinitely.
Every access to guest data is written to a tamper-evident audit log — who looked, when, and what they did — so you can show exactly how a registration was handled.
The data stays in Switzerland
Guest registrations are hosted exclusively in ISO 27001-certified Swiss data centres, with nothing replicated abroad — no US sub-processor, no EU fallback region.
Traffic is TLS 1.3, data at rest is AES-256, and everything is retained under the GDPR. If you ever cancel, there is a 90-day window to export your data before it is securely deleted.
What the guest gets in return
The guest-facing portal is in German, French, Italian and English, so a guest completes their registration in their own language.
Once checked in, the same guest can carry a digital guest card — a single QR that opens the barrier, the pool and the showers and unlocks partner discounts — so the registration they signed is also the thing that lets them in.
