Cookie policy

Last updated November 12, 2026.

Sandbox uses a small number of cookies and browser storage. None of them are for advertising, and none are sold or shared with ad networks.

What we store

  • Session cookie — keeps you signed in. Without it you would have to sign in again on every page. It expires when your session does.
  • Theme preference — remembers whether you picked light or dark mode.
  • Pending prompt— if you type a game idea on the home page before signing up, it is saved in your browser's local storage so the composer can pick it up after you finish signing up. It is deleted as soon as it is used.

Third parties

Stripe and Razorpay set their own cookies on their checkout pages, under their own policies. Google and GitHub do the same on their sign-in pages, if you use them.

Your control

Your browser can block or delete cookies. Blocking the session cookie signs you out — the app cannot keep you signed in without it. The theme and pending prompt are conveniences; blocking them only loses the preference and the saved prompt.
