Why Zinro needs these permissions and how your privacy is protected
Display Over Other Apps (Overlay)
EssentialAllows Zinro to render the floating edge tab, suggestion chips, and side panel directly over WhatsApp, Instagram, Telegram, and other apps.
Accessibility Service
EssentialEnables Zinro to detect the active chat input field and read the visible conversation text solely to generate relevant reply suggestions when you ask.
- We do NOT save, log, or record your chat conversations on our servers.
- Data is processed in-memory transiently only at the moment you request a suggestion.
- Passwords, payment screens, and non-chat apps are automatically ignored.
Blocked by Android "Restricted setting"?

- Go to phone Settings → Apps → Zinro.
- Tap the three dots (⋮) in the top-right corner.
- Tap "Allow restricted settings" and enter your phone PIN.
- Return to Zinro and toggle Accessibility ON.
