Privacy

Local progress: Zevlixa stores progress, preferences and mastery data in your browser. You can export or import a progress backup. Clearing browser/site data can remove local progress.

Speech practice: supported browsers may provide speech recognition. Zevlixa compares the recognized transcript with the practice sentence; it does not claim to provide a clinical or phoneme-level accent score. Typed comparison is available when recognition is unavailable.

Optional AI: when the Cloudflare Workers AI binding is configured, selected optional requests may be sent to the site’s own AI endpoint. The core local content does not depend on AI.

Advertising: third-party ad scripts are not loaded until you choose “Allow ads” on that device. If you select “Essential only,” the game remains usable without loading those ad scripts. You can reopen Ads privacy from the footer.

Contact/data requests: Zevlixa does not publish a dedicated privacy-contact address in this build. If an official contact channel is published later, privacy and data requests can be directed there.
