Frequently asked questions.
Everything you need to know about the product and billing.
How do I install this without touching theme code?
Install the app from Shopify, then add the Ring Sizer Pro Button app block to your product template in the Theme Customizer. No liquid edits are required, and you can manage copy, colors, button style, keywords, and size-option aliases from the app settings.
Where will the CTA actually appear on my storefront?
The button is shown only when the app is enabled, your monthly quota is not exhausted, and the product is detected as a ring product. Detection uses product signals like title/type/tags/collections/category plus size option patterns, and it avoids false positives like earrings or necklaces.
What happens after a customer finishes a measurement?
The result is converted into ring sizes (EU, US, UK, JP). If a matching variant option is found in the product form, the app auto-selects it and confirms selection to the shopper. If no exact option exists, the measured recommendation is still shown so customers can choose manually.
Which size systems and measurement modes are supported?
Shoppers can size by finger measurement or by matching an existing ring. The flow calibrates screen scale with a credit card reference and outputs sizes across EU, US, UK, and JP. By default the app auto-detects a product's preferred system from variant options, with manual override available in admin settings.
How do plans, usage limits, and data storage work?
Current plan limits are 25 (Free), 250 (Starter), and 2,000 (Growth) measurements per month, tracked per shop. When the limit is reached, the storefront CTA is automatically hidden until quota is available again. Measurement events are stored for analytics (mode, size result, matched option, product context), anonymous funnel events are available as an opt-in merchant setting, and camera images are not persisted by the app.
