Most requests are handled by the self-service tools below, with no waiting on a reply.
Manage your license
Can't find the original message with your key, or need to free up an activation slot? The license page can send your key again or reset your activations.
Upgrade an existing license
Before opening the full-price checkout, use the upgrade page with your current key. It requests a one-time discount code for that key, sent to the email address from your original purchase, or handed straight to the app if it is already activated on this computer. Buy with that code and the new key goes the same way — to your original purchase email, or straight into the app — regardless of what email address you use at checkout; your original key is untouched and keeps working for the version it already owns.
Bought a second copy instead of upgrading?
Within 30 days, use the refund link in the Paddle receipt for the new full-price purchase and explain the mistake. The new purchase can be refunded in full and only its new key is revoked. Your original key stays unchanged; use it on the upgrade page after the refund to request a discount code. See the refund policy for the complete process.
Download the app
Get the latest supported Windows version from the download page. If Thruline directs you to an older major version, its version-specific link opens the matching installer instead of silently substituting the latest one. macOS and Linux versions are in development. If your key is delayed or lost, use the license tools above to send it again.
Common questions
Purchase, activation, refund, and offline-use questions are answered on the home page FAQ.
Still stuck?
Email [email protected] and include the address you purchased with. This is also the right place to go if a purchase needs a closer look, rather than disputing the charge with your bank.
