Privacy policy — HUGO Pro Music

Last updated: 29 October 2026 · Versión en español

HUGO Pro Music works offline and has no user accounts. Only the ads in the free version, the purchase of HUGO Pro Music and the AI assistant use the internet; the assistant is optional and only works if you connect your own AI.

What data is stored: your songs, sheet music, annotations, setlists, recordings, settings and practice log. Everything is stored only on your device.

What the developer does NOT receive: the developer does not receive your songs or your personal data. The app has no server and no analytics of its own, and it does not sell data.

Ads (free version): the free version shows Google AdMob ads. To show them, Google's ads SDK may collect and share with Google the device's advertising ID, approximate location (from the IP address), ad interaction data and diagnostic and crash data, for advertising, measurement, analytics and fraud prevention. In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent before showing personalised ads, and you can change it at any time in Settings → HUGO Pro Music → Ad privacy. You can reset or delete your advertising ID in Android settings. More information: policies.google.com/technologies/ads

HUGO Pro Music (optional purchase): the purchase is made through Google Play. Google handles the payment; the developer does not receive your payment details. With HUGO Pro Music no ads are shown.

AI assistant (optional): if you choose to use it, you enter your own API key from an AI provider you choose (for example Anthropic/Claude, OpenAI/ChatGPT, Google/Gemini or another compatible one). Only when you press send, the app sends directly to that provider, over an encrypted connection (HTTPS), your message and the context needed: your musician profile (name, instruments, level, daily goal and a summary of your practice over the last 30 days) and, if you ask it to analyse a song, its details and content (chord sheet, MusicXML score or PDF). That processing is carried out by the provider under its own privacy policy. Your API key is stored only on your device, is not included in backups and is never sent to the developer. Conversations are not saved on the device.

Microphone permission: used only for the tuner, the recorder, the looper, recording over tracks and note recognition in the trainers. Audio is processed on the device and is only saved if you choose to save it.

Camera permission: used only if you choose “Scan with the camera” to photograph paper sheet music. Photos are stored only on your device.

Notifications: if you turn on calendar reminders, the app schedules local notifications on your device (for example, before a rehearsal). No notifications are sent from any server.

Sharing: the app only shares content (for example, the practice card or an exported file) when you ask it to, through the Android share menu.

Deleting your data: Settings → Data → Delete all data (this also deletes the API key), or uninstall the app.

This website: it uses no cookies of its own, no forms and no analytics.
