Why there is no cookie banner
These cookies are necessary to provide sign-in, security, and the project workflow you request. They are not used for advertising or cross-site tracking. Where the law allows, strictly necessary cookies do not require opt-in consent. If we later add analytics, personalization, or advertising cookies, we will update this notice and request consent where required before setting them.

You can block or delete cookies in your browser, but blocking these cookies will prevent sign-in and project handoff features from working. Auth0 and Stripe may set their own necessary cookies on their hosted domains when you use sign-in or checkout.
