# FAQ

> Answers to common questions about FlowLock: where the servers come from, why macOS won't open the app, and what to do if a subscription doesn't load.

## Does FlowLock sell VPN?

No. FlowLock is a client for the subscription you bought from a VPN provider. FlowLock has no servers of its own.

## macOS says FlowLock can't be opened

FlowLock is signed without an Apple certificate. Open “System Settings” → “Privacy & Security” → “Open Anyway”, or
run `xattr -dr com.apple.quarantine /Applications/FlowLock.app` (see [“Installation”](https://flowlock.cc/en/docs/install.md)).

## The subscription doesn't load

- Check the link: open it in a browser. It should download text or JSON.
- Some panels don't answer clients they don't know. In that case FlowLock retries the request with the v2rayN
  User-Agent by itself; if that doesn't help, set the subscription's User-Agent by hand (your provider will tell you
  which one).
- The panel limits the number of devices by HWID: free up a slot in your provider's dashboard.

## “The subscription administrator has limited the number of devices”

The subscription was added from a limited link, and all its places are taken. Contact your provider's support: their
contacts are shown in the same window.

## Connected, but sites don't open

- Try another server: switching works on the fly.
- In system proxy mode not every app follows the proxy. Turn on TUN.
- Check your rules: the site may have ended up in “direct” or “block”.

## What does FlowLock know about me?

Without an account and without subscriptions that carry a provider ID, the app contacts the FlowLock server only for
updates. A verified provider sees the device identifier, the system and the FlowLock version, but not your IP, sites
or traffic (see [“Privacy”](https://flowlock.cc/en/docs/privacy.md)). Check-ins for the provider are turned off with the “Tell the provider
I'm connected” setting. Diagnostics and traffic statistics are sent only if you turned them on.
