Documentation · Offline and device storage
Supported browsers and known limitations
Current iPhone Safari and Android Chrome are primary targets in browser and installed modes. Camera, OPFS, persistence and sharing vary, so every optional capability has a fallback.
Use a secure HTTPS origin and current browser version.
On iPhone, expect site storage to remain vulnerable to eviction and test installed-mode updates carefully.
File input replaces live camera; IndexedDB Blob storage replaces OPFS; buttons replace swipe-only comparison.
