Your audio never leaves your device
Audio files are not uploaded. Decoding, measurement, mastering and file writing all run inside your browser. We have no server that could receive your audio, and we never see your file names.
The only personal data we collect
If you voluntarily join the waitlist, we store the email address you submit. We use it once, to tell you when premium or the desktop app is available. We do not sell it, share it, or add it to any other list. Ask us to delete it and we will do so within 30 days.
Anonymous usage statistics
We use PostHog to count how the app is used. We send band values only — for example "3-5m" for length or "-12~-15" for loudness — never file names, never exact measurements, never audio. Cookies are not used for this (memory-only storage), and we honour Do Not Track: if your browser sends it, we collect nothing.
What we store on your device
Your language choice and a monthly count of how many tracks you downloaded are kept in your browser localStorage. Clearing your browser data resets both. Nothing in there is sent to us.
