Cookie Policy.

Sparks uses cookies and similar technologies that are necessary to run the product. We do not run third-party advertising cookies.

What we use

• Authentication — secure session cookies so you stay signed in (Supabase Auth).
• Preferences — local storage / cookies for theme and UI preferences you set.
• Security & reliability — short-lived tokens and CSRF protections on OAuth flows.

Control

You can clear cookies in your browser. Disabling authentication cookies will sign you out and prevent use of the app until you sign in again.
