Something not working, or a question before you buy? Write to contact@noctread.com and a human will answer.
Your key is shown on the confirmation page right after payment and is also emailed to you. If you no longer have either, email contact@noctread.com from the address you used at checkout — that is how we look the purchase up — and we will send the key again. A key is not tied to a device, so reinstalling your browser or your computer never costs you the licence.
Right-click the NoctRead icon → Options, paste the key into the Pro box and press Activate. The advanced engine is also free for your first 15 days after install, with nothing to enter.
NoctRead deliberately skips sites that already ship their own dark theme, so it never turns a dark app light. If you want it applied anyway, use the toolbar popup's per-site switch, or Alt+Shift+S. If a page still looks wrong with the advanced engine, the filter engine handles it differently — both are in the popup.
Alt+Shift+D dark mode on/off · Alt+Shift+S just this site · Alt+Shift+R Reading Mode. You can rebind them in your browser's extension-shortcuts page.
NoctRead Pro is a one-time payment, not a subscription — there is nothing to cancel. If it is not what you expected, email contact@noctread.com and we will refund the purchase through Stripe.
