Skintone (“we”) runs skintone.app, a foundation shade-matching site, and the Skintone Shade Finder app for Shopify stores. Questions about this policy or your data go to support@skintone.app.
When a store installs Skintone Shade Finder, we store the store's myshopify.com address, store name, the store's contact email, the access token Shopify issues to the app, and the catalog brand we match the store's products against. We use these to run the shade finder on that store and to contact the merchant about the service.
When the merchant opens the app, it reads the store's products (titles, vendors, product types and shade options, including swatch colours and images) to show which shade products we can match. For products we recognise, and products whose shades the merchant imports, we store the product's title, vendor and shade names, and for imported products the shade colours the merchant saves. We don't store product images, and the app has no access to orders, customers or payment information.
When a shopper uses the shade finder, the foundation they type and the shade they pick are sent to our server to calculate the match, and we count searches, picks and brand requests for each store without any shopper identifier. We don't ask for or receive names, email addresses, account details or order information, and the shade finder sets no cookies.
If a shopper chooses the camera option, the camera image is analysed on their device, in our camera page inside the store's shade finder. Only the measured skin colour is sent to calculate the match. Images and video are never uploaded or stored, and that page loads no analytics.
Our hosting provider keeps standard request logs, which include IP addresses, for a short period for security and to stop abuse.
We use PostHog analytics to see how the site is used: pages viewed, features used, device and browser type, approximate location derived from IP address, and recordings of on-page interactions.
The camera shade finder analyses the camera image in your browser. Only the measured colour values are sent to our server. Images and video are never uploaded or stored.
If you join early access, we keep the email address and store URL you give us and use them only to contact you about Skintone.
If you ask us to add a brand or shade, we keep what you asked for and, only if you choose to give it, your email address, which we use only to tell you when it's added. You can ask us to delete it at any time.
Vercel (hosting), Neon (database), PostHog (analytics) and Shopify (for the app). We don't sell personal data or share it for advertising.
When a store uninstalls the app, the shade finder stops on that store straight away. Shopify tells us 48 hours later, and we then delete the store's record, settings and access token.
Anyone can ask us to access, correct or delete the data we hold about them by emailing support@skintone.app. We reply within 30 days.
If we change this policy we'll update this page and the date below.
