Privacy policy

Last updated 25 October 2026

ThemeMerge (“the app”, “we”) is a Shopify app that compares and merges Online Store themes. This policy explains what information the app collects when a merchant installs it, how that information is used, and how long it is kept.

Information we collect

When you install the app, Shopify gives it access to your store. The app stores:

• Store details: your store's myshopify.com domain, the access token Shopify issues so the app can call the Shopify Admin API on your behalf, and the permissions you granted.
• Theme data: the names and IDs of your themes and the contents of their files. The app saves theme files as snapshots (for example, a baseline recorded when a working copy is made) and as merge records, which hold the versions of each changed file, your conflict decisions and the merged result.
• Task records: the status and progress of background tasks, such as analysing a merge.
• Plan: the app reads which ThemeMerge plan your store subscribes to. Shopify handles billing; we never receive payment details.
• Server logs: technical logs of requests to the app, which include your store's domain, the pages requested and any errors.

Information we don't collect

The app only has access to your themes. It does not access, request or store customer information, orders, products, or the names or email addresses of your staff. It uses no analytics, advertising or tracking cookies.

How we use information

Only to provide the app: comparing your themes, merging them, preparing downloads, and, when you choose to, writing a merged result into a theme. The app never writes to your published theme. We do not sell or rent your information, and we do not use it for advertising.

Sharing

The app runs on Amazon Web Services in the United States (us-east-1), which stores and processes the data described above on our behalf. Information is exchanged with Shopify to provide the app. We disclose information otherwise only if the law requires it.

Security

All connections to the app use HTTPS, the database is encrypted at rest, and access to the hosting account is restricted.

Retention and deletion

• Automatic theme snapshots are kept according to your plan: the newest 3 on Free, 90 days on Pro. A baseline that a working copy still depends on is kept until the data is deleted as described below.
• Server logs are deleted after 30 days.
• When you uninstall the app, its access token is deleted immediately and queued tasks are stopped. Shopify then asks the app to erase your store's data, 48 hours after uninstall, and the app deletes everything it stored for your store: snapshots, merges, tasks and store details.

Your rights

You can ask us at any time to access, correct or delete the information the app holds about your store, using the contact below. Because the app stores no customer information, customer data requests that Shopify passes to the app have nothing to return or erase.

Changes

If this policy changes, we will update this page and the date at the top.
