Cookie Notice

Last reviewed: 17 June 2026 · Version 1.0

Sparklemuffin uses only the cookies needed to make the service work. We do not use advertising or tracking cookies, and there is no behavioural profiling.

Essential cookies

Session / authentication — set when you log in to keep you signed in securely. These are set by our authentication provider, Supabase. Payment session — set by Stripe during the checkout process to handle your payment securely. These cookies are not retained after checkout.

These cookies are strictly necessary for the service to function. Under the Privacy and Electronic Communications Regulations (PECR) they do not require your consent, but we list them here for transparency.

If we introduce any non-essential cookies in future, we will update this notice and add a consent banner.

See our Privacy Policy for how we handle personal data more broadly.
