Short version. BassBoost Pro applies Android's built-in audio effects (EQ, bass boost, virtualizer, loudness) to your media. It does not record, analyse or upload any audio. EQ presets live on your device. The only network calls are Google Play Billing (subscriptions) and Google AdMob (rewarded ads on request).

1. Who we are

BassBoost Pro (package com.webtulip.bassboostpro) is published by Webtulip.

2. What information the app processes

2.1 Information you create

Stored in the app's private DataStore on your device. Never uploaded.

2.2 What the app does with audio

BassBoost Pro attaches to Android's global audio effect chain via android.media.audiofx APIs (Equalizer, BassBoost, Virtualizer, LoudnessEnhancer). These effects re-shape audio that other apps are playing. BassBoost Pro never accesses, records or analyses audio content. It only adjusts gain on frequency bands.
