No analytics or advertising identifiers are stored. Consent under § 25 TDDDG is therefore not required.

Your Rights

You have the right to information, correction, deletion, restriction of processing, data portability, and objection regarding the processing of your personal data. Right to object under Art. 21 GDPR: you have the right to object, on grounds relating to your particular situation, at any time to the processing of personal data concerning you that is based on Art. 6(1)(e) or (f) GDPR; this also applies to profiling based on those provisions. You may withdraw your consent to the processing of your email address for product updates at any time. The lawfulness of processing carried out before the withdrawal remains unaffected. Right to lodge a complaint with a supervisory authority: you have the right to lodge a complaint with a supervisory authority. The competent authority is the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (LDI NRW).

Obligation to provide data and automated decisions

Providing your account and contact data is required in order to use the service. No automated individual decision-making within the meaning of Art. 22 GDPR, and no profiling, takes place.

Product Updates

If you enter your email address in the signup form in our footer, we store it for the sole purpose of sending you occasional product updates — new fields, data freshness changes, and roadmap notes. The submission is delivered to us through Web3Forms. We ask you to confirm your subscription before we send anything further, and every message includes a way to unsubscribe. We do not share the address with anyone else, and we delete it as soon as you unsubscribe or ask us to.
