• Theme Editor Settings — the five technical settings that live in the theme editor (cart drawer fixes, extra cart events, stacking order, debug logging) and when each one helps.

• How-To: Manage the Bar, Translations, Analytics and Billing — everyday editing, localization, reporting, the free trial and plan changes.

• How Adds to Cart Are Counted — what consumes the monthly allowance and what happens at the limit.

• Troubleshooting and FAQ — common setup, theme, cart and billing questions.

Good to know

• One shop, one bar. Both Starter and Pro manage a single Sticky Bar. You can delete it and create a fresh one at any time; Pro does not add more bars.

• One-time theme step. Save the bar with Active on storefront on, then turn on the Sticky Cart app embed under Online Store > Themes > Customize > App embeds. Repeat when you publish another theme.

• Product pages only. Show the bar on every product, or only on the products and collections you choose.

• Usage counts successful bar adds. Loading or viewing the bar costs nothing. Starter includes 50 successful adds per month; Pro is unlimited.

• Plans. Starter is free. Pro is $1.99/month with unlimited adds, Analytics, Translations and priority support, and starts with a 14-day free trial the first time a store subscribes. Annual billing saves 20%.
