Questions
Is it a one-time payment?
Yes. One payment, no subscription, and all future Pro features of the product you bought are included.
How many machines can I use it on?
Use your key on your own machines. A key belongs to the person who bought it and is not to be shared or redistributed.
Does Pro work offline?
Yes. When you activate, the extension checks your key with Gumroad’s license API and caches the result, so Pro keeps working without a connection.
Can I get a refund?
Email hello@doorsofperception.dev with your Gumroad order; refunds are handled through Gumroad.
Do I get a receipt?
Yes. Gumroad issues the receipt for every purchase, and your license key is on it.
Why does Gumroad say “History Pro”?
History Pro is the previous name of Session Trail Pro. The option on Gumroad still carries the old label; it unlocks Session Trail.
Where do I enter my key?
In Session Trail, click the PRO badge in the panel’s toolbar. In Task Trail, run Task Trail: Enter Pro license key from the Command Palette. A Workbench key works in both. See Support.
