Privacy
Your video, every recording and the rendered file stay in your browser tab. Nothing you load or play is sent to a server. There are no accounts.
What the browser keeps
A few preferences (listening volume, reverb choice, drum pad settings, whether MIDI is switched off) are saved in your browser's local storage so they are the same next time. Clearing site data removes them.
What is measured
Page views are counted with Google Analytics on the live site only, never for automated visits or for the site owner. No analytics ever receives your video or audio.
