Overview

ApiChatcher (hereinafter referred to as "we" or "the App") is a multi-platform HTTP/HTTPS packet capture and debugging tool supporting iOS, macOS, and Windows, designed to help developers and testers capture, analyze, and debug network traffic. We respect and protect the privacy rights of every user. This Privacy Policy aims to provide detailed information on how we collect, use, store, and protect your personal information. Please read the following content carefully before using the App.

App Description

ApiChatcher is a multi-platform HTTP/HTTPS packet capture and debugging tool supporting iOS, macOS, and Windows. It helps users capture HTTP/HTTPS requests and responses, generate API documentation, export to Postman or Apifox, replay requests, rewrite responses, and use scripts for complex debugging requirements.

Data Storage and Processing

Data Storage Location

  • Local Storage: ApiChatcher stores all captured network traffic data locally on your device. This means your data is saved directly on your device, not on our servers. Therefore, your captured data is secure and private.

Account System

  • Optional Login: ApiChatcher provides an optional account login feature. You can register and log in to your account using your email address and a verification code. The login feature is optional, and you do not need to log in to use the core packet capture and debugging features of this application.
  • Purpose of Login: The login feature is solely used to synchronize your subscription status, allowing your subscription benefits to take effect across multiple platforms (iOS, macOS, Windows) and multiple devices simultaneously. We will not use your login information for any other purpose.
  • Account Usage Limit: A single account can only be used on up to 3 platforms simultaneously. The account is for your personal use only. Please do not share or lend your account to others.
  • Data Separation: Your account information is completely separated from your captured network traffic data. Logging in or not does not affect your local control over captured data.

Network Traffic Data

Captured Data

  • Local Processing: All captured HTTP/HTTPS requests and responses are processed and stored locally on your device.

User Data Collection

User Data We Collect

  • Data We Do Not Collect: ApiChatcher does not collect, store, or analyze your captured packet data, network traffic content, device information, location data, etc. All captured data is always stored locally on your device. We firmly believe that your data should solely belong to you.
