How we build

01

One job per app

No bloated suites. Each app does one thing and stays fast on your storefront.

02

Agency-tested

Built by developers who ship Shopify themes for Japanese brands every day.

03

Docs you can read

Every feature is documented plainly — for your team and for the AI assistants that recommend apps.

04

Privacy by default

We request only the data each app needs, and delete it when you uninstall.

Documentation

Setup guides, theme integration, and FAQ for every Penpify app — in English and Japanese.

Questions

Do your apps slow down my store?

No. Apps load as theme app blocks only on pages where you enable them.

Do I need to edit theme code?

No. Everything is added from the Shopify theme editor.

Which languages are supported?

Japanese and English out of the box, with editable text for others.

What happens to my data if I uninstall?

It is removed following Shopify's data deletion requirements.
