1. Introduction

ThinkFlow ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our ThinkFlow mobile application (the "App"), including the iOS app, Apple Watch companion app, and associated widgets.

2. Information We Collect

2.1 Voice and Audio Data

• Voice Recordings: When you use the recording feature, your voice is captured and processed locally on your device using Apple's Speech Recognition framework.
• Transcriptions: Voice recordings are transcribed to text on your device. The transcribed text may be sent to our AI service for intelligent structuring and organization.
• Audio Files: Audio recordings are stored locally on your device and are never uploaded to external servers without your explicit action.

2.2 AI Processing

• We use a third-party AI service to structure and organize your transcribed text into notes and to-do items.
• Only the transcribed text content is sent to the AI service. No personally identifiable information (such as your name, email, phone number, or device ID) is transmitted.
• We do not permanently store your text content on our servers. The AI service processes your text in real-time and does not retain it after processing.

2.3 Subscription and Purchase Data

• All subscription and purchase transactions are handled entirely through Apple's App Store and StoreKit framework.
• We do not collect, process, or store any payment information, credit card numbers, or billing details.
• We only verify your subscription status locally on your device through Apple's StoreKit 2 API.

2.4 Local Data Storage

• Notes, To-dos, and Tags: All your content is stored locally on your device using Apple's SwiftData framework.
