Privacy Policy

Your files stay local

MIDI Room parses and plays your .mid files entirely in your browser using the Web Audio API. Your MIDI files are never uploaded, stored, or shared — there is no server component that receives them.

Local storage

We use browser local storage to remember small preferences such as theme and tempo settings. This data never leaves your device and can be cleared at any time from your browser settings.
