Portvanta Import Fees – Privacy Policy

1. About This Policy

This Privacy Policy explains how Portvanta Import Fees ("Portvanta," "the App," "we," or "us"), provided under the name MINAMI App Design, processes information when Shopify merchants install or use the App.

Portvanta enables merchants to configure optional import-related service charges and review associated purchase-time amounts.

This policy applies specifically to Portvanta Import Fees and is separate from the privacy policy of the MINAMI online store.

For privacy-related inquiries, contact apps@f-minami.com.

2. Information We Process

We process information necessary to operate the App, including:

Store and App Information

• Shopify store, App, and installation identifiers
• Merchant-defined service rates, rules, and configuration
• App-managed product and resource identifiers
• Authentication information and limited operational records

Order and Checkout Information

When authorized by Shopify and the merchant, the App processes limited order and checkout information, including identifiers, timestamps, products, quantities, prices, currencies, discounts, taxes, shipping charges, transaction amounts, payment status, shipping destination country, and service-selection records.

This information is used to display and verify import-related service charges.

The App does not ordinarily request customer names, detailed addresses, email addresses, phone numbers, or payment card details.

We do not maintain a separate customer database or routinely store complete Shopify order or checkout records in our application database.

Privacy Requests

When Shopify sends a privacy-related request, we process the information necessary to authenticate, record, and respond to that request. We retain limited request metadata and cryptographic fingerprints rather than the original request payload.

3. How We Use Information

Information is processed only as necessary to:

• Provide and maintain the App
• Configure and calculate merchant-defined service charges
• Display and verify purchase-time amounts
• Authenticate Shopify connections
• Prevent unauthorized operations and maintain transaction integrity
• Diagnose service problems and maintain operational security
• Respond to privacy requests and applicable legal obligations

We do not sell personal information or use it for unrelated advertising or marketing.

4. Storage and Security

Portvanta uses Shopify and Cloudflare infrastructure to operate the App.

App configuration, installation information, encrypted authentication credentials, and limited operational and privacy-processing records may be stored using Cloudflare services.

We use security measures designed to protect this information, including encryption of stored authentication credentials, access controls, authorization checks, and safeguards against unauthorized changes.

No method of electronic storage or transmission is completely secure.

5. Service Providers and Information Sharing

We use the following service providers as necessary to operate Portvanta:

• Shopify: Store integration, authentication, checkout and order functionality
• Cloudflare: Application hosting, database services, and supporting infrastructure

These providers process information in accordance with their applicable terms and data protection arrangements.

The App does not automatically transmit merchant diagnostic information to ChatGPT or other AI services. Merchants may choose to copy and share diagnostic information when requesting assistance.

6. Retention and Deletion

We retain information for as long as reasonably necessary to provide the App, maintain security, address operational issues, or comply with applicable legal obligations.

Completed privacy-processing records and related audit records are generally scheduled for removal after approximately 30 days, subject to applicable retention requirements.

Unresolved privacy requests are retained until they are appropriately addressed.

When the App is uninstalled, authentication-related activity is stopped. App-held information is deleted as appropriate following the applicable Shopify privacy requests and verification of the affected installation.

Safeguards are used to prevent a request relating to an earlier installation from deleting data belonging to a newer installation.

Information retained independently by Shopify or other service providers is subject to their respective policies and obligations.

7. International Processing

Information may be processed through cloud infrastructure located outside the merchant's or customer's country.

Where applicable, international processing and transfers are subject to relevant legal requirements and service-provider safeguards.

8. Privacy Rights

Depending on applicable law, individuals may have rights to request access to, correction of, or deletion of their personal information, or to exercise other privacy rights.

For information processed by Portvanta, please contact apps@f-minami.com.

Customers with questions about their purchases or information held by a Shopify merchant should generally contact that merchant directly.

Where Shopify forwards a valid privacy request to Portvanta, we process it in accordance with applicable requirements.

9. Changes to This Policy

We may update this Privacy Policy when our services, information practices, legal obligations, or service providers change.

Any revised policy will be published with an updated effective date.

10. Merchant Agreement and Data Processing Terms

10.1 Contracting Parties

These terms are between the sole proprietor established in Japan who operates the MINAMI online shop and provides Portvanta Import Fees under the business name MINAMI App Design ("Provider," "we," or "us"), and the individual or business that installs or uses the App ("Merchant" or "you"). MINAMI App Design is the business name used by that proprietor for the App. Operator identification and business contact requests are addressed in Section 11.

A person accepting these terms on behalf of a business must have authority to bind that business.

10.2 Presentation and Acceptance

These terms, together with Sections 2–8 of this Privacy Policy, constitute the Merchant Agreement for the App. Please review them before installation. By proceeding with installation or use after receiving clear notice that proceeding constitutes acceptance and a reasonable opportunity to review these terms, you agree to them. If you do not agree, do not install or use the App.

Shopify's installation approval authorizes the requested access to your store. Acceptance of this Merchant Agreement remains subject to the notice and assent required by applicable law. Publication of these terms does not by itself establish acceptance by an existing Merchant.

10.3 App Services and Responsibilities

The App lets you configure optional, merchant-defined import-related service charges and review associated purchase-time amounts. It does not calculate statutory customs duties or import taxes. You are responsible for your service rates, customer disclosures, delivery arrangements, and obligations to your customers.

Provider is solely responsible for the App, including its development, operation, marketing, distribution, availability, and support. Shopify is not responsible for App defects or harm caused by installing or using it. Unless Shopify expressly states otherwise, Shopify does not provide assistance with installing or using the App. Provider, rather than Shopify, is solely responsible for liabilities arising from access to or use of the App, including Provider's handling, disclosure, or storage of Merchant Data.

For App assistance, contact apps@f-minami.com. No particular response time, uninterrupted availability, or error-free operation is guaranteed. Nothing in these terms excludes rights or liabilities that cannot lawfully be excluded.

10.4 Data Processing Scope and Instructions

For personal information processed on your behalf, you determine the processing purposes and lawful basis, and Provider acts as a processor or service provider to the extent applicable. Your authorized installation, configuration, and use of the App instruct Provider to process only the information described in Section 2 that is necessary for the purposes in Section 3.

Processing is limited to providing the App, calculating and reviewing merchant-defined service charges, authentication, security, technical support, and applicable legal and privacy obligations. The App does not use this information for advertising, marketing, behavioral tracking, or customer profiling, and Provider does not sell it. Any additional processing purpose requires an appropriate lawful basis and any required notice or consent.

You are responsible for the customer notices and permissions required for your store's processing. Selection of an optional service in the cart is not treated as blanket consent to unrelated personal data processing.

10.5 Security, Service Providers, and Privacy Requests

Provider applies the safeguards described in Section 4, including encryption of stored authentication credentials and access controls. App data stored in Cloudflare D1 is encrypted at rest, and App communications use encrypted transport. Access to information is limited to what is necessary for authorized operational purposes and is subject to applicable confidentiality duties. These measures do not constitute a guarantee against every security incident.

Shopify and Cloudflare support the functions described in Section 5. You authorize their use for those functions, subject to their applicable terms and data protection arrangements. International processing is subject to Section 7 and any additional safeguards required by applicable law; these terms do not themselves establish a transfer mechanism that is legally required but not otherwise in place.

Provider handles applicable privacy requests as described in Section 8 and reasonably assists with requests concerning information it holds or controls. Requests may require verification of the requester and affected installation. Security incidents affecting such information are handled, including required notifications, in accordance with applicable law and Shopify requirements.

10.6 App Fees

The App is provided free of charge. Merchant-defined service charges collected from shoppers are not App usage fees payable to Provider. Shopify subscriptions, shipping charges, customs duties, taxes, and other third-party costs remain separate. A paid App plan will not begin without your separate approval.

10.7 Ending Use, Retention, and Deletion

You may end use of the App by uninstalling it. Provider may suspend access where reasonably necessary to address a security risk, unlawful use, a material breach of these terms, or a platform requirement.

After uninstalling, App access and App-held information are handled as described in Section 6. Processing is limited to what remains necessary for applicable deletion, security, or legal obligations. Information is not retained longer than necessary, and mandatory deletion deadlines under applicable law and Shopify requirements take precedence over general retention descriptions in this Policy. Verification or unresolved processing does not extend a mandatory deadline. Any retention required by law is limited to that purpose and period.

Uninstallation does not promise immediate erasure from every system, reverse existing orders or payments, or remove obligations you have to your customers. Information held independently by Shopify and other service providers remains subject to their applicable terms and legal obligations. Confidentiality and data protection duties continue for as long as Provider retains relevant information.

10.8 Changes to These Terms

Updates are published with an updated date as described in Section 9. Publication alone is not treated as acceptance of a material contractual change where additional notice or consent is legally required. Changes do not apply retroactively to establish acceptance that was not previously obtained.
