Common questions

The extension still shows the free plan after paying

Open the settings page and choose Refresh licence. If that does not help, paste the licence key from your confirmation email under I already have a licence key.

I reinstalled Chrome or switched machines

If Chrome Sync is on, your licence follows your profile automatically. Otherwise use Restore a purchase.

How many devices can I use?

Up to five browsers per licence. Removing a licence from a browser frees its slot again.

What happens to my settings if I stop paying?

Nothing is deleted. Premium features stop applying, every setting stays exactly as you left it, and everything returns the moment you subscribe again.
