What do I get if I donate?

Your donation supports continued development and upkeep of Sudoku Spoiler. As a thank-you, ads are removed on your device — 30 days for $3, or 90 days for $5.

How it works

Your ad-free status is saved in your browser (or app, if installed) and expires automatically when the period ends. No account, no login. Donating again while you are already ad-free adds the new tier's days to your current expiry.

Restoring ad-free status

PayPal gives you a transaction ID after each donation. Paste your most recent transaction ID into the restore field on the donate page to unlock the same ad-free period on current device. Older transaction IDs only restore up to their own original expiry.

Privacy

We only store the PayPal transaction ID and the expiry date. No name, email, or payment details — PayPal handles all of that.
