Privacy Policy
Last updated November 13, 2026 · FlashDev, s.r.o.
This policy explains what Musicalio stores about you, why, and what you can do about it. We collect only what the app needs to work.
Who we are
Musicalio is run by FlashDev, s.r.o., which is the controller of your personal data. For any privacy question or request, write to hello@musicalio.app.
What we store
Your email address and name; your Google account ID if you sign in with Google; the sheet music you upload and the scores converted from it; your piece settings and practice preferences; your sign-in sessions; and a monthly count of conversions to enforce the free quota.
How we use it
Only to run the app: to sign you in, keep your library in sync across devices, convert your uploads into notation, and send sign-in and account emails. We don’t sell your data, show ads, or use your uploads to train models. Microphone audio for the tuner and practice modes is analysed in your browser and never leaves your device.
Who processes it
The app runs on Cloudflare, which hosts the service, stores the database and your files, runs conversions, and sends our emails. If you choose Google sign-in, Google confirms your identity and shares your name and email with us. If you buy Plus, Paddle (our reseller) processes the payment and keeps your billing details; we receive only your subscription status and a customer ID, never your card details. Data may be processed outside your country under these providers’ standard safeguards.
How long we keep it
Your data stays until you delete it. Deleting a piece removes its files; deleting your account in Account settings removes your profile, library and files at once. Sign-in codes expire after 15 minutes, and sessions end when you sign out or they lapse.
Your rights
You can see and change your details in Account settings, and delete your account there at any time. You can also ask us at hello@musicalio.app for a copy of your data, a correction, or deletion, and you may complain to your local data protection authority.
Changes
If we change this policy we’ll update the date above, and tell you by email about significant changes.
