1. Regarding our business model:

• Currently, our app is completely free with no paid features. All users can access all available features without any payment.
• We plan to introduce subscription features in the future, which will allow users to sync their favorite requests and configuration information across devices, but this functionality has not been implemented yet.
• Account registration is completely free and optional.
• There are no paid features, subscriptions, or in-app purchases in the current version.

2. Regarding account deletion:

• We have implemented an account deletion option in our app.
• Users can find the “Delete Account” link at the bottom of the user profile screen after logging in.
• This link directs users to our website (https://kainy.cn/SyncMeIn/privacy.html#close_my_account) where they can complete the account deletion process.
• The account deletion process is straightforward and does not require contacting customer service.

3. What user information is the app collecting using VPN?

SyncMeIn uses a VPN configuration to intercept and inspect HTTP/HTTPS traffic for debugging and development purposes.

The app collects the following information through the VPN functionality:

• Network request and response data (HTTP/HTTPS traffic) that passes through the VPN
• Domain names and URLs of websites and services accessed through the VPN
• Request headers and response data for analysis and debugging
• Connection metadata (IP addresses, ports) necessary for the proper functioning of the proxy service

The app does NOT collect or store:

• Personal user identification information
• Passwords or authentication credentials
• Browsing history beyond the current session (unless explicitly saved by the user)
• Device information beyond what’s necessary for VPN operation
• Location data or other sensitive personal information

4. For what purposes is this information collected?

The collected information is used exclusively for the following purposes:

• Traffic Analysis and Debugging: To help developers inspect, analyze, and debug HTTP/HTTPS requests and responses during app development
• Request Modification: To allow users to rewrite or modify requests for testing and development purposes
• Domain Filtering: To selectively capture only traffic from specific domains as configured by the user
• Script Execution: To enable users to run custom JavaScript scripts to process requests or responses for testing
• Local History: To provide a temporary record of captured traffic for analysis within the current debugging session

All data processing happens locally on the user’s device. The VPN functionality is designed as a development tool to help users debug their own applications and network traffic.

No, the data collected through the VPN is not shared with any third parties. All traffic data is:

• Processed locally on the user’s device
• Only stored temporarily in the app’s local storage
• Only accessible to the user of the app
• Not transmitted to external servers except when explicitly initiated by the user (e.g., when forwarding traffic to another device for debugging)

The app includes user authentication functionality, but this is solely for user account management and does not involve sharing the VPN-captured traffic data with third parties.

If users choose to export their captured traffic history (in HAR format), this exported data remains under their control and is not automatically uploaded to any server.

In summary

SyncMeIn is a developer tool that uses VPN functionality to provide local traffic inspection and modification capabilities, with all data processing happening on-device and no sharing of captured traffic with third parties。
