If your network access behaves abnormally, first check and adjust DNS settings in the Rules page.

The app has built-in support for:

1. Changing DNS settings after dial-up/connection.

2. DNS connectivity checks.

3. DNS pollution detection.

Where to configure: open the app main screen, go to Rules, then modify the default DNS request settings.

One-tap preset recovery: at the bottom of the Rules page, we provide built-in presets for common regions, including Mainland China, Hong Kong/Macau, and default profiles for countries/regions such as Iran and Russia.

Dynamic IP database update: the Rules page also includes dynamic IP database update, which you can run when needed.

Why detected DNS may differ from configured DNS:

DNS probing uses temporary domain resolution to identify the actual egress resolver IP within a DNS cluster, so the detected result may not be exactly the DNS address you entered.

For example, even if you configure Google Public DNS (8.8.8.8), the detected resolver may be another cluster node responding to your request.

To delete your account:

Open the app and go to Account -> Security -> Delete Account.

Please note:

1. Account deletion is permanent and cannot be undone.

2. Email verification is required before deletion.

3. After deletion, related payment records, usage records, and other associated data will be removed.

4. The account will be deleted regardless of whether you are a VIP member.

When you hit connection issues, unstable speed, or anything hard to reproduce, rich diagnostics help us troubleshoot much faster.

Recommended (best): use the in-app ticket / feedback flow. In recent builds you can attach profiles, network diagnostics, speed-test results, and detailed logs right inside the ticket so support can triage quickly.

Can't find the ticket entry? Open Help → About (or the equivalent section in your client) — you'll usually find shortcuts to logs and network diagnostics there; export or capture what you can, then reach out through whichever channel you prefer.

Tips: try to reproduce once before sending, note time, network type (cellular vs Wi‑Fi, rough region), and your app version; it speeds things up.

If you subscribed through Apple In‑App Purchase, Apple often attaches an introductory period (sometimes shown as a free trial — exact wording and length appear on Apple's checkout screen; seven days is typical).

During that period payment usually hasn't cleared yet, so the remaining time you see in the app (for example about seven days left) usually reflects the trial window, not your full monthly or yearly entitlement already granted.

After the trial: if you have not cancelled before it ends, Apple begins the paid subscription, and your membership duration then advances according to the plan you chose. You may cancel anytime during the trial from Settings → Apple ID → Subscriptions (or the subscription section in the App Store) if you don't want it to renew automatically.

Note: Exact billing timing follows Apple's receipt and subscription terms; wording may vary by region.

To see which country or region your Apple ID is registered in (for example US, Hong Kong, etc.), use Apple’s official account site.

Recommended: sign in with your browser and open the account information section—look for Country or Region.

Direct link (sign in required): Apple ID — Account information

Note: menus may vary slightly by language or iOS version. On iPhone you can also check under Settings → Apple ID → Media & Purchases / Payment & Shipping, or the region shown for the App Store account.

Your region affects which apps appear in the App Store and which payment methods are available. Use an Apple ID that matches the storefront you need, and follow Apple’s terms.
