This always works • Pause from the Quick Settings tile, the widget or the app Why KeyRelay uses Accessibility KeyRelay uses the Accessibility service to see the keys you press, so the keys you mapped can run the actions you chose. It notes the app in front for profiles and conditions, reads the text field you are in only for text actions, and checks whether the on-screen keyboard is showing. It taps, swipes or pinches only when you press a key mapped to one, at the spot you picked. Its only overlays are the spot picker, your floating buttons and the keep-screen-on window. It does not collect, store or send personal data, does not read your messages, screen or passwords, and runs nothing on its own. Turn it off anytime in Settings › Accessibility. The KeyRelay keyboard is optional and off until you turn it on. It types only what your mappings say, reads nothing, saves nothing and never types into password fields. Privacy • Key presses are handled in memory, never logged or stored • Mappings stay on your phone; backup and restore are free • No ads, no account, no analytics, no crash reporting Free: 5 mappings, short and long press, every action except screen taps, text snippets, Do Not Disturb and intents, starter sets, backup, share codes and the key tester. Pro removes the limit and adds the rest, once for life or yearly. KeyRelay is an independent app, not affiliated with any controller, keyboard, TV or phone maker.
