1. Introduction

Welcome to ToneSeed Fretboard Trainer ("we," "our," or "us"). This Privacy Policy explains how we collect, use, disclose, and safeguard information when you use the ToneSeed Fretboard Trainer mobile application (the "App") and the fretboard.toneseed.app website.

2. Information We Collect

ToneSeed Fretboard Trainer is designed to work offline and without an account. Your practice data and preferences are stored locally on your device by default. If you create an account, your data may also be synced to our cloud servers. We collect the following categories of information:

Account information - if you create an account, we collect your email address and authentication credentials. If you sign in with Apple or Google, we receive the basic profile information those providers share with us, such as your email and, where available, your name.
Practice and progress data - information generated as you use the App, such as completed sessions, answer accuracy, response times, XP, streak or activity counters, per-note statistics, interval statistics, bend training results, and whether specific fretboard positions have already been introduced.
Instrument presets and preferences - settings you configure, such as instrument type, string count, fret count, custom tunings, left-handed layout, active preset, note label style, tuner reference frequency, default training mode, language, theme, and haptics preferences.
Chord and reference data - chord favorites and other app content you save, including voicing details tied to your instrument preset.
Purchase and entitlement information - subscription status and purchase entitlement data needed to unlock ToneSeed Fretboard Pro features. Payments are processed by Apple, Google, and RevenueCat; we do not receive your full payment card details.
Usage analytics - events about how the App is used, such as onboarding progress, selected instrument, training modes, session completion, paywall interactions, and settings changes.
Device and diagnostic data - technical information such as app version, operating system, device details, crash reports, and diagnostics used to maintain app stability and compatibility.
Support communications - information you provide when you contact us, such as your email address, message content, and any diagnostic details you choose to include.

3. How We Use Your Information

We use the information we collect to:

Provide, maintain, and improve the App
Save your practice progress, presets, settings, chord favorites, and training history
Sync your progress across devices if you create an account
Process subscriptions, restore purchases, and determine whether you have access to Pro features
Analyze usage patterns so we can improve lessons, exercises, and app design
Diagnose crashes and maintain app stability
Deliver app configuration, compatibility, and force-update information
Respond to support requests and feedback

4. Data Storage and Sync

Your practice data, presets, chord favorites, and preferences are stored locally on your device. If you create an account, selected data is also synced to cloud servers so you can back up your progress and access it on another device. Synced data includes your instrument presets, practice statistics, completed sessions, chord favorites, and synced app settings.

We implement appropriate technical and organizational measures to protect your information, but no method of transmission or storage is 100% secure.

5. Third-Party Services

We rely on third-party service providers to operate the App. These providers may process your information on our behalf for purposes such as:

Authentication and cloud sync - Supabase provides account authentication and stores synced app data when you create an account.
Authentication providers - Apple and Google may process your information when you choose to sign in with their account services.
Analytics, diagnostics, and configuration - Firebase services help us understand app usage, diagnose crashes, and deliver remote configuration.
Subscription management - RevenueCat helps us manage purchase entitlement status and present subscription offers.
Payment processing - Apple App Store and Google Play process in-app purchases and subscriptions under their own terms and privacy policies.

Each third-party service operates under its own privacy policy, which we encourage you to review.

6. Microphone Access

ToneSeed Fretboard Trainer may request access to your device microphone for features such as the chromatic tuner, mic-verified note and interval exercises, and bend training. Audio is processed locally on your device for pitch detection. We do not record, store, or transmit microphone audio.

7. Data Retention

Local data remains on your device until you uninstall the App, clear app data, or reset your progress in the App. If you have an account, your cloud data is retained for as long as your account exists. Analytics, crash, purchase, and diagnostic data is retained according to the retention policies of the respective service providers.

8. Account Deletion

You can delete your account at any time from within the App settings. When you do, your account and synced personal data are permanently erased from our cloud servers, and local app data on your device is cleared during the deletion process. An anonymized audit record of the deletion may be retained for security and operational purposes.

9. Your Rights

Depending on your jurisdiction, you may have the right to:

Access the personal data we hold about you
Request correction of inaccurate data
Request deletion of your data
Object to or restrict processing of your data
Request a copy of your data in a portable format

To exercise any of these rights, please contact us at the email address below. We will respond to your request within a reasonable timeframe.

10. Children's Privacy

The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of changes by updating the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
