Privacy policy — Teiki Subscriptions (Shopify app)
Updated 2026-10-22. Developer: Rulestamp (ReadyStack) · [email protected]
What the app accesses and why
- Products and selling plans (read_products, write_purchase_options): to create subscription plans and attach them to the products you choose.
- Subscription contracts created by this app (read/write_own_subscription_contracts): to charge due billing cycles, apply the price or interval changes you schedule, skip a delivery when you or the customer ask, and retry failed payments (Pro).
- Customer name and email (customers scope): read from Shopify only at the moment a notice is sent — a change notice you scheduled, a charge reminder (Standard and Pro) or a failed-payment notice (Pro). The customers write permission is used only to ask Shopify to send its own secure "update your payment method" email.
- Customer payment method id (read_customer_payment_methods): only to tell Shopify which card the update email is about. We never see card numbers.
What we store (Cloudflare Workers KV)
- Your shop's access token and refresh token, encrypted (AES-GCM).
- Your settings (notice days, reminder days, sender name, reply-to address) and your shop name, email and currency.
- Scheduled changes: the plan, the new discount or interval, the date it applies, and the ids of the affected subscription contracts. No customer names, emails or addresses.
- Small counters keyed by contract id: reminder sent for a date, payment-retry count (deleted after 30–40 days).
Emails
Notices are sent through Resend (resend.com) from [email protected] with your shop as the reply-to address. The email content is passed to Resend for delivery only; the app keeps no copy.
Customer accounts and storefront
The storefront block and the customer account page run in the shopper's browser and talk to Shopify directly; they send nothing to us.
Deletion
When you uninstall the app, or Shopify sends shop/redact, we delete everything we hold for your shop. customers/data_request and customers/redact are verified and answered: we hold no personal data of your customers.
Billing
Paid plans are charged by Shopify on your Shopify bill. We receive only the plan status from Shopify.
AI
The app uses no AI service on your data.
Requests
[email protected] — we answer within 2 business days.

アクセスする情報と理由
- 商品と定期プラン:定期プランを作り、選んだ商品に付けるため。
- このアプリが作った定期契約:請求日が来た分の請求、予約した価格・間隔の変更の適用、スキップ、支払い失敗時の再請求(Pro)のため。
- お客様の名前とメールアドレス:お知らせを送るその時だけ Shopify から読みます(変更のお知らせ・次回請求の予告・支払い失敗のお知らせ)。顧客の編集権限は、Shopify 自身の「お支払い方法の更新」メールを送ってもらうためだけに使います。
- お支払い方法の ID:更新メールの対象を Shopify に伝えるためだけ。カード番号は見えません。
保存する情報(Cloudflare Workers KV)
- ショップのアクセストークン・リフレッシュトークン(AES-GCM で暗号化)
- 設定(通知期間・予告日数・送信者名・返信先)と、ショップ名・メール・通貨

- 契約 ID ごとの小さな記録(予告メール送信済み・再請求の回数。30〜40日で自動削除)
メール
お知らせは Resend(resend.com)経由で [email protected] から、返信先をショップにして送ります。本文は配信のためだけに Resend に渡り、アプリは控えを残しません。
削除
アンインストール時、または Shopify から shop/redact が届いたとき、ショップについて保存している情報をすべて削除します。customers/data_request・customers/redact は署名を検証して応答します(お客様の個人情報は保存していません)。
お支払い
有料プランは Shopify の請求書で Shopify が請求します。
