How we use your personal information

Depending on how you interact with us or which Services you use, we may use personal information for the following purposes:

• Provide, tailor and improve the Services. We use your personal information to provide you with the Services, including to perform our contract with you, process your payments, fulfill your orders, remember your preferences and the items you are interested in, send notifications related to your account, process purchases, returns, exchanges or other transactions, create, maintain and otherwise manage your account, arrange for shipping, facilitate returns and exchanges, enable you to post reviews, and create a customized shopping experience for you, such as recommending products related to your purchases. This may include using your personal information to better tailor and improve the Services.

We use your personal information for marketing and promotional purposes, such as sending marketing, advertising and promotional communications by email, text message or postal mail, and showing you online advertisements for products or services on the Services or other websites, including based on items you previously purchased or added to your cart and other activity on the Services.

How our Shopify apps handle information

We offer the following apps on the Shopify App Store. Each app processes information about the Shopify stores that install it ("merchants") and their customers on the merchant's behalf, only to provide the app's features. We do not use this information for advertising or sell it to third parties.

All apps

• Our app servers and databases run on services provided by Render, Inc.
• We store the credentials needed to access Shopify (such as access tokens) in the app database.
• When an app is uninstalled, or when we receive a shop data deletion request (shop/redact) from Shopify, we delete that merchant's data stored in the app database. Settings saved in the merchant's store app settings (metafields) and images saved as files may remain in the store.
• SAKU Receipts and SAKU Blog Duplicate use Slack to notify us about server health (CPU and memory). No personal information is sent.

SAKU Receipts

• The app reads order, draft order, customer name, company (B2B) and store information to display and print documents such as receipts on the spot. Customers' personal information and order details are not stored in the app database. The recipient name is entered each time a document is printed and is not stored.
• Customers can view receipts for their own orders from the Thank you page, the Order status page and store pages (limited to the logged-in customer, people who know the order's confirmation number, and contacts of the B2B company).
• The company information, logo and company seal images entered by the merchant are stored in the store's app settings and in Shopify Files. A history of settings changes (the ID of the staff member who made the change and the fields changed; the setting values themselves are not stored) is stored in the app database.

SAKU Simple Noshi

• The noshi (Japanese gift wrapping paper) details a customer selects on the product page (such as noshi type, inscription and name) are stored in Shopify as cart and order information. They are not sent to the app server or stored in the app database.
• Merchant settings are stored in the store's app settings, and noshi images are stored in Shopify Files.

SAKU Simple Gift Options

• The gift details a customer selects (such as wrapping and gift message) are stored in Shopify as cart and order information. They are not sent to the app server or stored in the app database.
• Merchant settings are stored in the store's app settings.

SAKU Thanks Custom

• On the Thank you page and the Order status page, the app reads the order's payment status, amount and order count, and the customer's tags and email marketing consent, to decide what to show.
• Records of issued coupons (order ID, customer ID, coupon code and expiry date) and records of customers who consented to email marketing (order ID, customer ID and date/time; email addresses are not stored) are stored in the app database. Coupon records are deleted 30 days after they expire.
• If a customer gives consent, the app updates the customer's email marketing consent in Shopify. Issued coupons are recorded in Shopify discounts and customer metafields, and Shopify Flow is notified.
• A log of merchant staff actions (staff ID and the action taken) is kept for 180 days.
• When we receive a customer data deletion request from Shopify, we delete the matching records; when we receive a data request, we provide the records we hold.

SAKU Blog Duplicate

• The app reads the store's blog articles, templates (metaobjects), products (when the product card feature is used) and theme settings to duplicate, update and publish articles. It does not handle customers' personal information.
• The app database stores only the number of duplications and setup progress.

SAKU Food Labeling

• The app creates and updates product food labels (metafields), ingredient masters (metaobjects), collections and icon images (files). It does not handle customers' personal information and stores nothing in the app database.
• The storefront "Find allergen-free products" feature receives the allergens a customer selects and returns matching products. To prevent excessive access, the visitor's IP address is used temporarily in server memory but is not stored.

SAKU B2B Monthly Invoice

• Information handled: the name, company name, email address and address of business customers registered by the merchant; information about orders to be invoiced (order number, date, line items, amount, tax and payment status); records of received orders (order number, amount, payment status, payment method name and whether the order is invoiced; no customer information is included, and records older than 60 days are deleted); and issuer information entered by the merchant (company name, address, qualified invoice issuer registration number, bank account for transfers, logo and square company seal images).
• Purpose: used only to create invoices (PDF), send invoice emails when the merchant chooses to, and control which payment methods are shown at checkout. Payment receipts are not recorded.
• Access to Shopify data: the app reads orders and customers and configures a payment customization (to control which payment methods are shown). It does not change order details or payment status. Logo and company seal images are stored in the app database.
• Subprocessors: Render, Inc. (hosting and database) and Resend, Inc. (sending invoice emails).
• Retention and deletion: when the app is uninstalled, business customer, order, invoice and settings data is deleted (only the numbering record used to prevent reuse of invoice numbers is kept until we receive a shop data deletion request from Shopify; it contains no personal information). When we receive a customer data deletion request from Shopify, we delete that business customer's information and the records of their orders and invoices. If you need copies of issued invoices, save the PDFs before deletion. When we receive a data request, we provide the information we hold to the merchant.

 

Use of Google Analytics

Our Shopify apps SAKU Receipts, SAKU Simple Noshi, SAKU Simple Gift Options, SAKU Thanks Custom and SAKU Blog Duplicate use Google Analytics to measure how the app admin screens are used (such as the types of pages viewed) so we can improve the apps. No personal information about stores or their customers is sent. Nothing is measured if your browser has Do Not Track or Global Privacy Control turned on. For how Google handles data, see the Google Privacy Policy.

 

Third-party websites and links

The Services may provide links to websites or other online platforms operated by third parties. If you follow links to sites not affiliated or controlled by us, you should review their privacy and security policies and other terms and conditions. We do not guarantee and are not responsible for the privacy or security of such sites, including the accuracy, completeness or reliability of information found on these sites. Information you provide on public or semi-public venues, including information you share on third-party social networking platforms, may also be viewable by other users of the Services and/or users of those third-party platforms without limitation as to its use by us or by a third party. Our inclusion of such links does not, by itself, imply any endorsement of the content on such platforms or of their owners or operators, except as disclosed on the Services.

 

Children's data

The Services are not intended to be used by children, and we do not knowingly collect any personal information about children under the age of majority in your jurisdiction. If you are the parent or guardian of a child who has provided us with their personal information, you may contact us using the contact details set out below to request that it be deleted. As of the Effective Date of this Privacy Policy, we do not have actual knowledge that we "share" or "sell" (as those terms are defined in applicable law) personal information of individuals under 16 years of age.

 

Security and retention of your information

Please be aware that no security measures are perfect or impenetrable, and we cannot guarantee "perfect security." In addition, any information you send to us may not be secure while in transit. We recommend that you do not use unsecure channels to communicate sensitive or confidential information to us.

Technical and organizational measures for data protection

To protect your personal information, we have implemented the following technical and organizational measures:

Access control

• Access to the Shopify API is limited to the minimum required: we only read order information and are not granted write access
• Access to customer data is restricted to our application servers and is not open to external systems

Data encryption and communication security

• All communication is encrypted using the industry-standard HTTPS (SSL/TLS) protocol
• API credentials and secret keys are managed securely as environment variables and are never written directly in source code

Data minimization

• We do not store customer data permanently; it is used only during Shopify API calls and for as long as needed to provide the service
• We limit the personal information we collect to what is needed to provide the service

Security incident response

In the unlikely event of a security incident, we will take the following steps:

1. Immediate response: As soon as an incident is detected, we start investigating its scope
2. Containment: Where needed, we take emergency measures such as temporarily stopping systems and revoking API keys
3. Notification: We notify affected customers and the relevant authorities in accordance with applicable laws and regulations
4. Root cause analysis and prevention: We analyze the root cause, document measures to prevent recurrence, and improve our operations
5. Records and reporting: We record all incident responses and report to relevant parties as needed

How long we retain your personal information depends on different factors, such as whether we need the information to maintain your account, to provide the Services, comply with legal obligations, resolve disputes or enforce other applicable contracts and policies.
