Privacy Policy

Guitar Mentor ("we", "us") builds tools that help guitarists learn, practise and perform, powered by our music intelligence, PlugAI. This policy explains what we collect, why, and the choices you have.

What we collect

• Account data — when you Sign in with Apple we receive a user identifier and, if you allow it, your name and email address.
• Practice data — your songs, setlists, streaks, XP, lesson progress and related activity, so the app can pick up where you left off.
• PlugAI conversations — the prompts you send and the responses generated, used to deliver and improve the feature.
• Audio & song content — audio files you choose to import or analyse, and the stems, chords, sections, lyrics you provide, and MIDI derived from them. Live microphone input for the tuner and Chord Assist is processed on your device to detect pitch and chords and is not recorded or uploaded unless you explicitly save or import a song.
• Subscriptions & purchases — when you start a free trial or subscribe to Pro, our payments partner RevenueCat records your subscription status and purchase history. The payment itself is processed by Apple; we never receive your card details.
• Diagnostics & usage — aggregated crash reports and basic product-interaction data to keep the app stable and improve it.

How we use it

To run the app's features, sync your library across your devices, manage your subscription and enforce fair-use limits on the free and Pro plans, and to maintain and improve PlugAI's quality. We do not sell your personal data, and we do not use it to track you across other companies' apps or websites.

Service providers we share with

We rely on trusted providers, under agreements that protect your data:

• Apple — Sign in with Apple and App Store payments.
• Google Firebase and Google Cloud — authentication, crash reporting (Crashlytics), backend hosting and data processing.
• RevenueCat — subscription and entitlement management.
• Cloudflare R2 — storage for imported audio, generated stems, exports and analysis files.
• DeepSeek — PlugAI chat, coaching and text generation.
• Groq — speech-to-text transcription when lyrics or vocals are processed from user-imported audio.
• Replicate — audio analysis tasks such as source separation, chord detection, note extraction and lyric alignment.
• Firecrawl and LRCLIB — web lookup and lyric metadata features where available.

Your choices & rights

• Use the app as a guest, with reduced data collection.
• Request a copy of your data, or its deletion, at any time.
• Revoke microphone access in iOS Settings — the tuner and Chord Assist simply won't run.

Deleting your account

You can delete your account at any time in the app (Profile → Delete account). This permanently removes your profile, song analyses and setlists from our servers and wipes Guitar Mentor's data from your device. Deleting your account does not automatically cancel an active App Store subscription — manage or cancel that in your App Store subscription settings.

Data retention & security

We keep your data only as long as needed to provide the service or as required by law, and protect it with encryption in transit and access controls.

Children

Guitar Mentor is not directed to children under 13, and we do not knowingly collect their data.

Changes to this policy

We may update this policy as the app evolves. Material changes will be reflected here with a new "last updated" date.
