Privacy Policy

Introduction

Welcome to Quill, an iOS companion app for PostHog. This Privacy Policy explains how we collect, use, and protect your information when you use our app.

Information We Collect

Quill collects very limited personal information:

• Name (Optional): We may ask for your name during signup. Providing your name is completely optional.
• PostHog API Key: We collect and securely store the PostHog API key you provide to enable the app's functionality.

How We Store Your Information

We follow Apple's recommended security practices:

• Your PostHog API key is stored securely in the iOS Keychain, which provides a high level of encryption and protection.
• Any optional information you provide (such as your name) is stored locally on your device.
• Quill has no servers. All personal information is stored on device.

Usage Data and Analytics

Quill collects anonymous usage data to help us improve the app:

• We send anonymous tracking data to PostHog about certain events within the app, such as screen views and metrics created.
• All analytics data is collected anonymously and cannot be traced back to individual users.
• This data helps us understand how users interact with our app and identify areas for improvement.

Data Sharing

We do not sell, trade, or otherwise transfer your personally identifiable information to third parties. The anonymous usage data collected is only used for analytics purposes through PostHog.
