Privacy Policy

1. Introduction

Knighthouse Labs ("we," "our," or "us") is dedicated to protecting your privacy. This Privacy Policy explains our practices regarding the collection, use, disclosure, and safeguarding of information when you use our applications, services, and websites.

We build privacy-conscious software. Our core design philosophy is to minimize data collection and ensure that your personal information remains strictly under your control.

2. Information We Collect

Depending on the specific app or service you use, we may collect the following types of information:

• Device and Usage Information: Anonymous telemetry, operating system version, device model, app performance metrics, and crash logs to help us identify and resolve technical issues.
• User-Provided Information: Information you voluntarily provide when contacting support, submitting feedback, or requesting assistance (such as your email address).
• Local App Data: For apps that process audio, files, media, or local documents (such as Minimalist Guitar Tuner), all audio processing and pitch analysis occurs locally in real-time on your device. We do not transmit, record, or store your microphone audio or sound input on remote servers.

3. How We Use Information

We use collected data solely to:

• Deliver, operate, maintain, and improve our software and applications.
• Diagnose technical bugs, performance bottlenecks, and app crashes.
• Respond to your direct customer support inquiries and communications.
• Comply with applicable legal obligations and prevent misuse.

We do not sell, rent, or trade your personal information to data brokers or third-party advertisers.

4. Third-Party Services

Our applications may utilize trusted infrastructure providers to deliver essential features (such as Apple App Store infrastructure, Cloudflare edge hosting, and anonymous crash reporting). These third parties process data only to the extent required to deliver their specialized functions and are bound by strict data protection standards.

5. Data Storage and Security

We apply industry-standard technical and organizational security measures to protect information against unauthorized access, loss, misuse, or alteration. While no method of digital transmission or storage is 100% impenetrable, we continually assess and update our practices to maintain high data integrity.

6. Your Rights & Choices

Depending on your jurisdiction (including the EU GDPR and California CCPA/CPRA), you may have specific rights regarding your personal information, including:

• The right to request access to any personal data we hold about you.
• The right to request the correction or complete deletion of your data.
• The right to opt-out of optional diagnostic telemetry within app settings.

To exercise any of these rights, you may reach out to us at any time using the contact details below.

7. Children's Privacy

Our services and applications are not directed to individuals under the age of 13. We do not knowingly collect personal information from children. If we discover that a child has provided us with personal information, we will take immediate steps to delete such data.

8. Changes to This Policy

We may update this Privacy Policy periodically to reflect updates in our apps or legal requirements. When updates occur, the "Last Updated" date at the top of this page will be revised.
