This Privacy Policy applies to Lexo (com.lexo.keyboard), published by K4Y Apps. It explains what data the app collects, shares, and how you can control it.
Lexo is a local-only keyboard: everything it does - text prediction, autocorrect, personalization, and all ML inference - runs entirely on your device. No keystrokes or typed text are ever collected, transmitted, or included in any diagnostic report. There is no account, no cloud sync, no usage analytics, and no advertising of any kind. Crash reporting is off by default: nothing is sent unless you turn on the optional "Send crash reports" setting at Settings > Advanced > Other. If you do turn it on, anonymous crash and diagnostic logs are sent to Firebase Crashlytics to help fix bugs, and you can turn it off again at any time.
The following data is sent off your device by services we operate or treat as service providers. It is used only to keep the app working and to fix bugs; it is not sold, and it is not used to profile you or to track how you use the app.
| Category | Data type | Purposes | Optional |
|---|---|---|---|
| App info and performance | Crash logs | App functionality | Yes |
| App info and performance | Diagnostics | App functionality | Yes |
The app does not share any data with third parties.
Lexo is not directed at children under 13. We do not knowingly collect personal information from children. If you believe we have, please contact us at hello@k4yapp.com and we will delete it.
If we make material changes to this privacy policy, we will update the "last updated" date above. Continued use of the app after any changes constitutes acceptance of the updated policy.
If you have questions or concerns about this privacy policy, please contact us at hello@k4yapp.com.
