Frequently asked questions
What is Grbit?
Grbit is a rule-based proxy client and network utility for iPhone. It connects your device to proxy servers you provide, routes traffic according to rules you write, and includes tools for monitoring and debugging your own device's network activity.
Does Grbit provide servers or a VPN service?
No. Grbit is a client tool only. It does not include, sell, or operate any servers, and it has no service subscription of its own. You connect to infrastructure you host yourself or obtain from a provider of your choice.
Why does Grbit ask for VPN permission?
iOS requires apps that manage device traffic to use Apple's Network Extension framework, which appears as a VPN configuration in Settings. This is how the system hands traffic to the app for rule matching on your device. It does not mean your traffic is sent to us; we operate no servers.
Which protocols and formats are supported?
Grbit's built-in engine targets commonly deployed proxy protocols such as Shadowsocks, VLESS (including REALITY where configured), Trojan, Hysteria2, TUIC, AnyTLS, and MASQUE, plus selected compatibility paths. Not every transport combination or legacy variant is enabled. Some formats can be imported for display but are marked unsupported for the full-device tunnel until they pass our release checklist. We also import widely used subscription list formats, including Clash-style configurations. If something you rely on is missing, email us with an example (secrets removed).
Where is my data stored?
On your device. Configuration, rules, and diagnostic output stay local, with credentials in the iOS Keychain. The app has no accounts and no analytics, and we cannot see your traffic. Details are in the Privacy Policy.
How do I report a bug or request a feature?
Email us with your iOS version, your Grbit version, and what you expected versus what happened. Screenshots and steps to reproduce make fixes much faster. Feature requests are welcome; concrete examples of what you are trying to do help most.
Where are the release notes?
Each version is listed on the Release Notes page: what the tunnel actually runs, which protocols are enabled, default behavior, and what that version deliberately omits. App Store What’s New is a shorter extract of the same facts.
