WangYuYun Privacy Policy
In effect since Sep 17, 2026
We do not log your browsing. This policy sets out exactly what we do collect, why, and for how long.
On this page
1. Scope
This Privacy Policy explains what information Vigorously LLC ("we", "us") collects when you use WangYuYun (the "Service"), why we collect it, how we use and retain it, and what rights you have. It applies to our client apps, our website, and our backend services.
2. What We Do Not Log
The core commitment of the Service is that we do not log what you do online. We do not collect or store:
- the sites, domains, or IP addresses you visit;
- any part of the content you transmit;
- DNS queries;
- any mapping between source and destination addresses during a session.
Our server nodes count only the upstream and downstream bytes attributable to each credential within a time window, for billing and capacity planning. Those counters contain no destination information.
3. What We Collect
3.1 Account information
- email address (when you register with email);
- an irreversible hash of your password (we cannot recover your password);
- display name and avatar, if you choose to provide them;
- the subject identifier returned by Apple or Google when you sign in with them.
If you start a trial with a device identifier, we store only a hash of that identifier and do not require an email address.
3.2 Device and client information
- device identifier, name, and model;
- operating system version and app version;
- the brand app and platform in use;
- push token, if you enable notifications.
We use this to enforce device limits, deliver notifications, assess compatibility, and troubleshoot.
