Privacy

Your audio never leaves your device.

• No microphone permission. The cleaning and testing tools only play sound — they never listen.
• No audio upload. Every tone is synthesized locally with the Web Audio API.
• No backend processing. There is no server that sees your audio because there is no audio data to send.
• No accounts. Personalization (run count, last used tool, last result) lives in your browser's localStorage only.
• Minimal analytics. We tally anonymous event counters on-device (e.g. cycles completed, reported outcomes) to compute honest improvement rates. No audio, files, or identifiers are collected.
