Free first. Pro when it earns its place.

Outcome
What Pro actually gives you
A scoped ISP Evidence Report
A timestamped outage timeline, speed-test log and measured download/upload against your advertised plan. The report shows dates, time zone and monitoring gaps; outages and gaps are clipped to its period. Pro follows your retention setting: 7, 30, 90 days or all recorded history. Results support a conversation with your provider; they do not prove fault ownership.
Automation instead of babysitting
Scheduled speed tests fill the trend chart while you work; session mode scores a whole gaming session or video call for jitter and packet loss.
History that survives the week
Free retains up to 7 days. Pro lets you set longer retention in Settings. Report periods are 7, 30 or 90 days, or all recorded history at the maximum retention setting. Longer retention preserves future evidence; it cannot restore data already removed.
Good to know
Before you buy
7-day free trial, no card
Every Pro feature is free for 7 days. The trial ends by itself — nothing charges automatically. Start it from any Pro gate inside the extension.
Renewal
Monthly renews each month, Yearly each year, until you cancel. Lifetime never renews. Cancel anytime from the license-management link in your license email to stop the next renewal; you keep Pro until the paid period ends.
Refunds
Payments are non-refundable except where applicable law requires otherwise. Cancelling stops a future renewal; it does not refund an already-paid billing period.
Activation
With the extension installed, checkout can activate Pro in that browser automatically. You can also select Activate license in the popup, including during a trial, then paste the emailed key in Settings → Plan → Already purchased. Keys start with IHC-.
Devices
Each license covers up to 3 devices. Revoke an old device anytime from the license-management link.
