What happens when I uninstall a try-on app?

Why theme app extensions uninstall clean

Looksy is built as a Shopify theme app extension, which is the key detail. Extension blocks are rendered through Shopify's own framework rather than pasted into your theme files, so when you uninstall the app, Shopify simply stops rendering its blocks. The try-on block disappears from your product pages and your theme's Liquid files are untouched, because they were never edited in the first place. There is no cleanup step and nothing to hunt for in your code. This is standard behavior for any app built this way, and it is one reason theme app extensions became Shopify's recommended approach.

Legacy apps that pasted Liquid are a different story

Older try-on apps — and older Shopify apps generally — often installed by writing snippets directly into theme files: a script tag in theme.liquid, a snippet include in the product template. Uninstalling that kind of app removes the app but not the code it left behind, which can mean dead script calls, broken snippet references, or leftover markup quietly slowing pages. If you are replacing a legacy app, open your theme's code editor after uninstalling and search for the app's name across your Liquid files. Remove what you find, or duplicate the theme first and test the cleanup there before publishing.

Billing and unused credits: check before you uninstall

Uninstalling a Shopify app cancels its recurring subscription — that part is handled by Shopify, not the app. What is worth checking first is anything you have prepaid. On Looksy's paid plans, monthly photo credits and any additional credits bought at the per-credit rate are tied to the app, so confirm with support whether unused credits are refundable before you uninstall rather than after. Also check the timing against your billing cycle so you are not paying for a month you will not use. Two minutes of checking beats discovering the answer once the account is gone.

What happens to emails, analytics, and shopper photos

Sort your data into what you keep and what you lose. Emails already synced to Klaviyo or handled through Shopify Flow live in your own accounts and survive the uninstall — confirm the sync is current before removing the app. Assume in-app analytics — what shoppers tried on, added to cart, and bought — disappear with the app, so export or note anything you want to reference first. For shopper photos, ask the vendor directly how uploads are retained and deleted after uninstall; Shopify requires apps to support data-erasure requests, but retention specifics vary by app, and rules differ by region, so take real legal advice on your obligations.
