Good to know

Shopify only lets you edit the code of a paid theme you own. Theme trials can't be edited.
Checkout pages don't use your theme, so forms on checkout aren't tracked. Contact, newsletter, account and other store forms are.
Don't paste the line into Shopify's “Customer events” custom pixels. Those run in a sandbox without access to your page, so Formleak can't see your forms there.
Updating or switching your theme can drop code edits. Check the line is still there afterwards.

Based on Shopify's own help pages: Shopify: edit theme code, Shopify: custom pixels. Menus change from time to time; if something looks different, their help pages have the latest.
