These terms cover your use of ZUPI: Pulse Shield. By playing, you agree to them.
ZUPI is a free arcade reflex game. All 600 levels are playable by everyone at no cost, offline, with no energy meter and no waiting. Ads appear between some levels from level 25 onward.
ZUPI Ad-Free Monthly is an auto-renewing subscription with a length of 1 month, priced at USD 5.99 per month in the United States. Your own currency and price are shown on the purchase screen before you confirm.
It removes the ads between levels. That is all it does: it grants no extra lives, no levels and no scoring or ranking advantage, so the leaderboard stays fair for everyone.
Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically for the same price and length unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in Settings → your name → Subscriptions. Cancelling stops future renewals; it does not refund the period already paid for. Deleting the app does not cancel the subscription. Refunds are handled by Apple under Apple's policy, not by us.
An account is optional and only syncs progress and places a name on the global leaderboard. Keep your credentials to yourself. Player names are checked server-side; names that are abusive or impersonate others may be reset, and scores obtained by tampering with the app may be removed.
ZUPI is provided "as is". We work to keep it running correctly, but we do not guarantee it will always be available or error-free.
We may update these terms or the game over time. Continued play after a change means you accept the update.
