Landra runs in your browser, not inside the Shopify admin. Clicking Landra in your admin's Apps list opens Landra itself, so you won't find an uninstall button there. You uninstall it from your store's settings.
Uninstall the app
In your Shopify admin, click Settings (bottom left).
Click Apps.
Find Landra and click the three dots (...) next to it.
Click Uninstall.
Choose a reason if you like, then click Uninstall again.
Landra loses access to your store straight away.
What happens to your pages
Pages you already published to Shopify stay on your store, and they keep working while your Landra plan is active. Landra can't update or remove them until you install the app again. Your pages in Landra, drafts and published, aren't deleted.
Uninstalling the Shopify app and deleting a page in Landra are separate actions. Keep the original page in Landra while you still need the version on your store. Do not assume that a page left in Shopify will keep working after you delete its Landra source. Exported HTML can also depend on Landra-hosted assets.
To take a page off your store, do it in Landra before you uninstall: open the page, click Publish, choose Shopify, click Unpublish, then Delete. If you've already uninstalled, delete it in your Shopify admin under Online Store > Pages.
Uninstalling doesn't cancel your plan
Landra bills you directly, not through Shopify, so uninstalling the app doesn't stop your plan. To cancel, go to Billing in Landra, click Manage my plan and cancel there.
Leaving Landra completely? Cancel your plan first, and keep the app installed until your plan ends. When it ends, Landra takes its pages off your store for you, but only while the app is still installed. Then uninstall. If you uninstall before your plan ends, delete the leftover pages yourself under Online Store > Pages, because they stop displaying properly once your plan ends.
Changed your mind?
Install the app again from the Shopify App Store. Your store reconnects to the same Landra account, and your existing pages become updatable again. If the Landra page asks, click Connect store.
