Privacy Policy

Effective date: March 1, 2026

The short version: Guitar Shark collects minimal data, never sells your information, doesn't show ads, and processes microphone audio entirely on your device. Your practice data stays on your iPhone unless you choose to sync it.

1. Who We Are

Guitar Shark is developed and operated by devZane, LLC, a Texas limited liability company ("we," "us," "our"). This policy describes how we collect, use, and protect information when you use the Guitar Shark mobile application ("App") and website at guitarshark.app ("Website").

2. Information We Collect

Information You Don't Give Us (Free Tools)

When you use Guitar Shark's free tools without creating an account, we collect no personal information. Specifically:

Practice data (streaks, session time, progress) is stored locally on your device using Apple's on-device storage
Microphone audio used by the tuner and ear training is processed entirely on-device — it is never recorded, stored, or transmitted
No analytics SDKs or third-party tracking code is included in the App

Information You May Give Us (Account & Subscription)

If you create an account or subscribe to Shark Mode, we may collect:

Account information: Email address and display name
Subscription status: Whether you have an active subscription (managed entirely by Apple — we never see your payment details, credit card number, or Apple ID password)
Synced practice data: If you opt into cross-device sync, your practice history and progress may be stored on our servers
Support correspondence: If you email us, we retain that communication to help resolve your issue

Information Collected Automatically

Website: Our website is hosted on Cloudflare Pages. Cloudflare may collect standard web server logs (IP address, browser type, pages visited) as part of its infrastructure. See Cloudflare's Privacy Policy
App: We do not include any analytics frameworks, crash reporting SDKs, or advertising identifiers in the App. Apple may collect anonymized usage data through its own systems if you have opted in via iOS Settings

3. How We Use Your Information

To provide, maintain, and improve the App
To manage your account and subscription
To respond to your support requests
To send important service-related communications (e.g., security notices)

We do not use your information for marketing, profiling, or targeted advertising.

4. What We Never Do

We never sell, rent, or trade your personal information
We never show advertisements
We never track you across other apps or websites
We never record, store, or transmit microphone audio
We never share data with data brokers

5. Third-Party Services

Apple App Store & StoreKit: Handles all subscription billing, payment processing, and receipt validation. Apple's terms and privacy policy govern these transactions
Cloudflare: Provides website hosting (Cloudflare Pages), API infrastructure (Cloudflare Workers), and data storage (Cloudflare D1/R2). Data may be processed in Cloudflare's global network. See Cloudflare's Privacy Policy
Resend: If we send you transactional emails (e.g., account verification), they are delivered via Resend. See Resend's Privacy Policy

We do not integrate any social media SDKs, advertising networks, or third-party analytics tools.

6. Data Storage & Security

Account and synced data is stored on Cloudflare's infrastructure, which employs encryption at rest and in transit. We use industry-standard security measures to protect your information, but no system is 100% secure.

Local practice data is stored on your device using Apple's sandboxed storage and is protected by your device's passcode and encryption.

7. Data Retention & Deletion

Local data: Remains on your device until you delete the App
Account data: Retained while your account is active. You can request deletion at any time by emailing support@guitarshark.app — we will delete your data within 30 days
Support emails: Retained for up to 2 years for quality and legal purposes

8. Children's Privacy

Guitar Shark is suitable for users of all ages. We do not knowingly collect personal information from children under 13 (or the applicable age in your jurisdiction). If you believe a child has provided us personal information, please contact us and we will delete it promptly.

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
Data portability

To exercise any of these rights, email support@guitarshark.app. We will respond within 30 days.

10. California Residents

Under the California Consumer Privacy Act (CCPA), California residents have additional rights. We do not sell personal information. We do not use personal information for cross-context behavioral advertising. You may contact us to exercise your CCPA rights at support@guitarshark.app.

11. International Users

Guitar Shark is operated from the United States. If you access the App from outside the US, your information may be transferred to and processed in the United States, where data protection laws may differ from your jurisdiction.

12. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you through the App or by updating the effective date above. Continued use after changes constitutes acceptance.
