Contact the developer

Developer: Zhun Ren
Support email: 3071355785@qq.com

For a technical issue, describe the steps, what you expected and what happened. Include the App version, device model, iOS version or screenshots where helpful. Hide unrelated personal information and do not send passwords, verification codes or full payment details.

Purchased Pro is not showing

1. Check that the subscription is active in iPhone Settings → your name → Subscriptions.
2. Make sure Media & Purchases uses the Apple Account used for the purchase and that you have a network connection.
3. Select Restore Purchases on the App’s membership screen. If access is still missing, contact the support email.

Restoring purchases does not buy another subscription.

Cancellation, trials and plan changes

Manage or cancel in iPhone Settings → your name → Subscriptions → Sonencia / 频率. To avoid renewal, cancel at least 24 hours before the current subscription or trial period ends. Deleting the App does not cancel a subscription.

The annual plan’s 3-day free trial is available only to users eligible under Apple’s rules. Check Apple’s screen for the end of a trial, access after cancellation and when a switch between annual and quarterly plans takes effect.

Billing and refunds

Request a refund from Apple at reportaproblem.apple.com. The Developer can help investigate App or access issues, but cannot directly change Apple bills or approve or issue Apple refunds. Your statutory rights remain unaffected.

Playback or visual issues

Check media volume, Bluetooth or other audio outputs, mix levels and timer settings. If tilt interaction does not respond, try the touch-drag interaction in the App. If the issue persists, send reproducible steps. Avoid deleting the App as a first troubleshooting step, as this may remove local settings.

Local records and privacy

Your profile, favourites, presets and listening statistics are stored on your device. The Developer cannot remotely read or restore them from a server. Restore Purchases restores valid purchased access, not these local records. See the Privacy Policy for photos, motion data, backups and deletion, and the Terms of Use for service rules.
