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.

Sourdough Tracker is the German alternative to A paper notebook: 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

Paper has a real advantage: nothing more honest than a flour-dusted page that's been near the dough. It also has a real disadvantage: you can't search it, you can't sort it, you can't filter feeds vs bakes, and the photos live in a separate device. Sourdough Tracker is the digital equivalent that respects what paper does well - one-tap entries, no nag, your data stays yours - while adding what paper can't: search, filtering, photos in line with the entry they belong to, and per-starter sharing. Many bakers happily run both.

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. Sourdough Tracker brings all three together: dedicated servers in Germany, Finn Glas (sole proprietor) registered in 72461 Tailfingen, German law on the contract. The gap to A paper notebook is usually that one of these three is missing.
