FAQ

No.

It runs on App Blocks alone and never edits your theme code directly.

We add no global script, so your pages stay fast — and no trace is left in your theme after you uninstall.

All the data our apps handle — size charts, materials, model-worn info, aggregated counts and more — is stored inside your own Shopify store.

We keep none of it in an external database we run, and you can export it to CSV anytime.

No.

Features like fit feedback store only anonymous, aggregated counts.

We never collect or store anything that identifies an individual shopper — name, address, IP, cookies and the like.

You can cancel your subscription anytime, and billing stops from the next cycle.

Given the nature of a digital service, we’re unable to refund time already served.

No.

After install, the dashboard walks you through three steps: choose the features you’ll use, create a template (size charts and more come pre-built), and assign it to products.

Placing the block on your product page is one click from Settings — no theme code, no developer.

68 templates cover tops, pants, dresses, skirts, outerwear, shoes, socks, bras, hats and more.

Pick one and the right columns (chest, waist, inseam, foot length, under-bust, head circumference…) appear automatically, with cm/inch and US/UK/EU/JP sizes where a conversion applies.

Hats use a compact head-circumference table with its own measurement diagram.

No — and that’s deliberate.

Recommendations are rule-based: the measurements a shopper types are matched against your size chart using the sizing principles behind the European EN 13402 standard and JIS, and each suggestion explains itself (e.g. “the length runs about 4 cm shorter than yours”).

Everything runs in the shopper’s browser — nothing is sent to your store or to us, and there are no per-use fees.

And unlike AI recommenders, it needs no purchase history to learn from, so it is just as accurate on day one of a brand-new store.

Shoppers can tap once to say an item ran small, true to size, or large.

Only anonymous counts are stored — no personal data.

Once votes accumulate, the product page can show real fit confidence like “most say true to size”, which reassures the next buyer.

(Pro feature)

Returns are imported from a CSV you upload — there is no automatic sync with orders or inventory, by design, to keep the app light and stable.

Reasons in English or Japanese are auto-classified into too small / too large / other, so you can see exactly which product’s info to fix.

(Pro feature)

Free covers size charts, browser-based fit finder, product FAQ, basic material/care display and CSV export.

Pro adds model-worn info, complete-the-look, detailed material/fit profiles, fit feedback, size confidence, returns analysis, CSV import and bulk assignment for a flat $12.99/month (or $129.99/year).

Every install starts with all Pro features free for 30 days — no credit card; your data stays even if you don’t upgrade.

It stays in your store.

Everything you entered lives in Shopify’s standard storage, so uninstalling deletes nothing, reinstalling picks up right where you left off, and you can export to CSV anytime.

No lock-in — on purpose.

Lightness is the core design goal.

The storefront runs as a Shopify App Block only, with zero global scripts; the only JavaScript is the size estimate and the fit vote, both confined to the block.

That’s how we avoid the “heavy, crashes, breaks my theme” problems common in this category.

The product-page display supports English, Japanese, German, French, Spanish and Italian (anything else falls back to English).

The admin follows your Shopify account language (English/Japanese).

Through the support contact on the App Store listing, or via mitasu.tech’s support page.

Inside the app, the printable Handover guide summarizes your settings, data status, each screen’s role and a weekly/monthly routine — handy for staff handoffs too.
