Requires a real app install (not a bookmark shortcut) and Notifications permission.

Notifications

Allow alerts when a coupon is due. After you Install the app, Android can also remind you while it's closed.

Your data

Everything stays on this device (IndexedDB, with a localStorage backup). Photos are stored only on this device. Nothing is uploaded. Safari can still wipe unused site data after 7 days unless you Add to Home Screen.

Checking storage…

Install as an app

Android (Chrome): Tap ⬇ Install when it appears (or Chrome’s Install app). That installs a real app with no URL bar — not a Chrome shortcut. If you already added a shortcut that still shows the name and URL at the top, remove that icon and Install again.
iPhone / iPad (Safari): Share (□↑) → Add to Home Screen.
