Your licence
Get your key.
Enter the email you paid with and your key comes back. Keys are worked out from the purchase rather than kept in a database, so this page answers today and it answers in two years.
Download it
One file, whether you bought one tool or all eight. Unzip it, open
chrome://extensions, switch on Developer mode, click Load unpacked
and pick the folder.
Paste this key into the panel
The panel opens by itself. Expand the licence line, paste, press Activate.
If something is wrong
A key that will not activate is almost always a key that was copied short. Select the whole
line, from SIDECAR-1. to the last character, with no line break in the middle.
If the lookup finds nothing, check the address on your Stripe receipt rather than the one you usually use: confirmations go to whatever was typed at checkout. Email help@sidecarstudios.org and it gets sorted by hand.
