Is Dark Mode & Grade What-If for Blackboard Learn safe?

Clean risk

Dark Mode & Grade What-If for Blackboard Learn sends the license key to the vendor's own server only to unlock its paid tier.

The extension's dark-mode styling and grade what-if calculator run entirely locally in the page, with no network activity. The only outbound request happens when a user enters a license key to activate the paid 'Pro' tier: the key and a product identifier are sent to the vendor's own Supabase backend, which returns whether the license is valid. That result is cached locally and silently re-checked roughly twice a day for users who already activated a license.
