Plug: Size Chart — by Plug Software

Last updated: September 24, 2026

Plug: Size Chart lets a merchant build size charts in the Shopify admin and show them on their storefront. This page explains what the app stores, what it never collects, and how to have it erased.

In short: we store the size charts a merchant creates and the settings that style them. We collect nothing about the shoppers who view those charts — no names, no orders, no tracking, no advertising, and we never sell data to anyone.

Who we are

The app is built and run by Plug Software. In this policy, “we” means Plug Software and “you” means the merchant who installed the app.

What the app does

Merchants build size charts — tables of measurements, headings, notes, images and videos — and choose which products or collections show them. The app writes each chart to the relevant products as a Shopify metafield, and the theme extension renders it on the product page.

What we store

What we do not collect

The Shopify permissions we ask for

We ask for nothing else. If a future feature needs another permission, Shopify will ask you to approve it before it takes effect.

Where your data is kept

Charts and settings are stored in our database, on servers we control, and reached only over encrypted connections. Images and videos you upload are stored in your own Shopify Files and served by Shopify’s CDN — not by us. Size charts published to products live in Shopify as metafields on those products.

Who else sees it

Nobody. We do not sell, rent or share your data, and we use no advertising or analytics services inside the app. The only third party involved is Shopify itself, and the hosting and database providers that run our servers on our instructions.

How long we keep it, and how to have it erased

We also answer Shopify’s shopper data requests: because we hold no shopper data, there is nothing to hand over or erase.

Security

All traffic runs over HTTPS. The app signs into Shopify with short-lived session tokens rather than cookies, access tokens are stored server-side only, and every request from Shopify is verified before it is acted on.

Your rights

Depending on where you are, you may have the right to see, correct, export or erase the data we hold about you, or to object to how we use it. Email us and we will act on it within 30 days at the latest.

Changes to this policy

If we change how the app handles data, we will update this page and the date at the top. Meaningful changes are also announced in the app.
