The Service is provided "as is." We strive for reliable operation but cannot guarantee uninterrupted availability.

Liability is limited to intent and gross negligence. In cases of slight negligence, we are only liable for breaches of essential contractual obligations, limited to foreseeable, typical damages. This does not apply to damages arising from injury to life, body, or health.

You may delete your account at any time. We reserve the right to suspend or terminate accounts that violate these Terms.

Upon cancellation of a paid subscription, access continues until the end of the paid period. After that, the account reverts to the free tier (Pawn).

We reserve the right to modify these Terms. Material changes will be communicated with reasonable notice via email or within the Service. Continued use after changes take effect constitutes acceptance.

These Terms are governed by the laws of the Federal Republic of Germany. The place of jurisdiction is Berlin, to the extent permitted by law. The UN Convention on Contracts for the International Sale of Goods (CISG) does not apply.

For consumers within the EU, mandatory consumer protection provisions of the country of residence apply in addition.
