Who is my contractual counterparty?

Finn Glas, a German sole proprietor based in 72461 Tailfingen, Germany. Address, press contact under §18(2) MStV and every disclosure required by §5 TMG live at /imprint.

Where is the data stored?

On dedicated servers we operate ourselves, physically located in Germany. Records, attachments, audit log, embeddings - all in the same EU jurisdiction. Backups stay within Germany at other physical locations and roll off on a 30-day window. We deliberately don't name the exact provider or data centre - it doesn't help the customer and would make operator changes a public event.

Which law applies in case of a dispute?

German law, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection rules of your country of residence remain unaffected. Venue is the registered seat of the operator (see /imprint), where legally permitted. No arbitration clause - you have the same legal recourse as with any other German vendor.

Can I get German-language support?

Yes. Both co-founders reply in German and English. No outsourcing, no ticket queue, no bot replies - you talk to someone who wrote the code.

How does the invoice + refund work?

Stripe issues a PDF invoice automatically after every payment, with VAT shown where applicable (the German Kleinunternehmer status under §19 UStG can drop the VAT line - the invoice is still fully bookkeeping-grade). Refund is self-serve in account settings: within the first 30 days of any new paid period you can refund the most recent charge yourself - no email, no exit interview. Full text in /terms §4.

Contact Book is the German alternative to Notion: hosted in Germany, German operator of record, German law applies. Three things that travel together for a reason - any one of them on its own is half a promise.

At a glance

A Notion CRM template is a great starting point. It's free, it's flexible, and it works for the first month. After that, three things tend to break: cadence reminders are flaky, life-event reminders rely on calendar tricks, and adding a custom field to a contact gradually fills the page with property pills nobody cleans up. Contact Book is the next step up - the same idea, but with the relationship-specific surface baked in.

Three pillars together

Three pillars that travel together

Hosted in Germany alone means little if the operator of record is a Delaware LLC - the CLOUD Act follows the seat, not the server. A German operator alone means little if the servers sit in Virginia - the access risk lives there. German law alone means little if both of those are missing - the venue clause cannot solve a data problem. Contact Book brings all three together: dedicated servers in Germany, Finn Glas (sole proprietor) registered in 72461 Tailfingen, German law on the contract. The gap to Notion is usually that one of these three is missing.
