Installation and use
LingoKey is installed like any App Store app, but iOS requires a separate one-time step to add a third-party keyboard. Follow the complete setup guide.
Privacy and Full Access
Full Access is the iOS permission that lets a third-party keyboard communicate over the network. It is necessary for cloud translation, but it does not make every keystroke a translation request. Read the plain-language privacy explanation.
Translation quality and modes
Different messages need different priorities. Instant mode favors speed; Professional mode is intended for more polished wording. You should always review important legal, medical, financial, or safety-critical text before sending it.
Natural, Casual, Formal, Business, and Social styles describe the requested voice. They can improve fit for a situation, but they do not turn automated translation into professional human review.
Languages
Source keyboards and translation targets are not the same list. LingoKey provides dedicated input for Simplified Chinese, English variants, Spanish, French, and German, while the target selector includes more than 100 languages and regional variants. See the detailed language guide.
Incoming messages and undo
For text you received, copy it and open clipboard translation. For text LingoKey just replaced, use undo while the surrounding field remains unchanged. These are separate, explicit workflows and neither one continuously monitors your typing or clipboard.
Lingo PRO and App Store billing
Apple shows the actual local price, renewal period, and any introductory offer you are eligible to receive. Restore Purchases uses the Apple Account that made the original purchase. Deleting the app does not cancel the subscription.
