Legal basis
Strictly necessary cookies and storage entries do not require consent (§ 25(2) no. 2 German TDDDG, Art. 5(3) ePrivacy Directive); the processing is based on Art. 6(1)(b) and (f) GDPR. If we ever use optional services, we will ask for your consent first; until then they are not loaded.
Stripe's payment page
When you buy credits, you move to Stripe's payment page (checkout.stripe.com). Stripe sets its own cookies there, among other things for fraud prevention; Stripe's cookie policy applies.
Deleting
You can delete cookies and stored data in your browser at any time. You are then signed out, and your language choice is reset.
