Is Sonic Equalizer free to download?
Yes, the core app is free to download on Google Play. Optional Pro and Lifetime plans unlock additional features like the 10-band EQ, all 18 themes, and the 3D Virtualizer.
How do I cancel my subscription?
You can cancel your subscription any time through your Google Play account → Subscriptions. The premium features will remain active until the end of your current billing period.
The app stopped working after a few hours — what do I do?
This is usually caused by Android's battery optimisation settings killing background apps. Go to Settings → Battery → App Optimisation and exclude Sonic Equalizer to keep it running continuously.
Does the equalizer work with all music apps?
Sonic Equalizer works system-wide and enhances audio from most Android apps including Spotify, YouTube, YouTube Music, and local media players. Some streaming apps restrict third-party EQ access.
How do I request a refund?
Refunds are handled by Google Play. Visit your Google Play Order History within 48 hours of purchase for an instant refund, or contact Google Play support for purchases older than 48 hours.
Is my audio data stored or shared?
No. Sonic Equalizer processes audio locally on your device. We do not record, store, or transmit your music or any audio content. See our
Privacy Policy for full details.
