How can we help?

Contact support@thuvassery.com.

Reporting a problem

Include the app version, phone model, Android version, what you expected and the steps that caused the problem. A screenshot can help. Do not send passwords, payment-card information, private keys or purchase tokens.

Coaching voices

Device Voice uses installed offline English text-to-speech voices. If none are available, install one through your phone's speech settings. Expressive Voice requires compatible imported packs; there is no public pack download at present.

Backing up games

Use Settings → Storage & Backup to export games and preferences before clearing app data or uninstalling. Voice models, prepared audio, credits and subscription credentials are excluded.

Subscriptions and payments

Subscriptions are not yet enabled in the current test build. Once available, purchases, renewals and cancellation will be managed through Google Play. Uninstalling an app does not cancel a subscription.
