NFC Guardian: Tap Pay Alerts

Stay in control of your phone's contactless payment radio. NFC Guardian
watches your device's NFC status in the background and reminds you to
turn it off once you're done tapping to pay — so it's never left on
longer than it needs to be.

WHY IT MATTERS
Your phone's NFC chip can stay active well after you've finished a
contactless payment. Most people forget to switch it off, leaving tap-to-
pay live at all times. NFC Guardian closes that gap with a simple, smart
reminder system — no complicated settings, no guesswork.

HOW IT WORKS
• Live NFC status on your home screen — see at a glance if NFC is on or off
• Smart reminders when NFC has been left on unused, so you can turn it
off in one tap
• Payment-aware detection — when your wallet app is open and you're
actively paying, we stay quiet and let you pay in peace
• One-tap deep link straight to your NFC settings — no digging through
menus
• Weekly history so you can see how often NFC gets left on and build a
better habit over time
• Home screen quick-settings tile for instant access

BUILT FOR PRIVACY
NFC Guardian runs entirely on your device. There are no servers, no
accounts, no logins, and no data ever leaves your phone. Your NFC status,
your reminders, and your history stay local — always. This isn't a
payment app and never intercepts, reads, or processes any transaction.
It simply watches your phone's NFC radio state and nudges you to manage
it.

WHO IT'S FOR
Anyone who uses Google Wallet, Samsung Wallet, or any tap-to-pay app and
wants an extra layer of everyday security awareness — commuters who tap
to pay on transit, frequent contactless shoppers, and anyone who prefers
to keep NFC off by default and only on when they need it.

ONE-TIME PURCHASE
No subscriptions, no recurring charges. Pay once and the app is yours —
every future update included.
