Why we don't ask for consent. Under the Privacy and Electronic Communications Regulations, we do not need your consent for a cookie that is strictly necessary to provide a service you have asked for. That includes automatic authentication. This cookie:
- is
HttpOnlyandSecure; - cannot be read by scripts;
- is stored by us only as a one-way hash.
Payments. When you pay, you are taken to Stripe's own checkout page. Stripe sets its own cookies there, for fraud prevention and to process your payment. Stripe's cookie policy explains them.
Changes. If we ever add a cookie that is not strictly necessary, we will ask for your consent before setting it, and update this page first.
