“No API Cost” Clarification

This app includes no external API usage — all processing happens locally on the user’s device.

FFmpeg Audio Processing: The app uses a locally integrated FFmpeg library to apply voice filters and audio transformations. No online server or API calls are made during processing.
Text-to-Speech (TTS): The TTS feature uses the device’s built-in native TTS engine (Android/iOS). It does not rely on any external or paid APIs like Google Cloud or OpenAI. This ensures no internet connection or subscription is required for text-to-speech functionality.
Offline Functionality: All core features — recording, applying effects, playback, and saving — work completely offline. An internet connection is only needed if users share audio through social or messaging apps.
No Ongoing Costs: Buyers will not incur any subscription or API fees after purchase. All voice processing and text-to-speech operations run locally.
