Terms of Service

1. Acceptance of Terms

By using the UK-EU Customs Calculator for Shopify ("App"), installing it in your Shopify store, you accept these Terms of Use ("Terms"). If you do not agree with any of the following terms, do not install or use the App.

2. Business Model

Business model: You are provided with SaaS (software access), not purchasing a license or ready-made code. Customer pays for access to the calculation tool available through Shopify App Store.

3. Intellectual Property

All source code, graphics, algorithms, and HS category classifications are the exclusive intellectual property of the App creator (Rafał Stybliński).

You are not permitted to:

• Copy, reproduce, or distribute the App's source code
• Perform reverse engineering, decompilation, or disassembly of the App
• Extract or reuse the HS category database for commercial purposes
• Create derivative works based on the App without explicit written permission

The App is provided as a service (SaaS). You receive access rights only, not ownership of any intellectual property.

4. Service Description

The App provides estimated calculations of customs duties and VAT for shipments from the United Kingdom to European Union countries. Calculations are based on:

• Current EU customs regulations (as of 2026)
• HS codes (Harmonized System) for 30 predefined product categories
• Official VAT rates for 27 EU countries
• €3 flat handling fee (from July 2026)
• €150 threshold for duty exemption

5. Legal Status - Information Tool Only

6. Disclaimer - Calculator Provides ESTIMATED Values

This is key to avoiding lawsuits if the system calculates 0% instead of 12% due to an incorrect HS code selected by the merchant.

We are not responsible for:

• Differences between estimates and actual customs amounts
• Incorrect product category mapping by the merchant
• Changes to customs regulations after the App's update date
• Delays or errors in deliveries caused by customs issues
• Financial losses resulting from use of the App

7. Payments and Subscriptions

Payments are processed by Shopify International Limited as your billing agent.

Free Plan ($0/month):

• 10 calculations per month
• Standard disclaimer (cannot be edited)
• No cancellation needed (free plan)

Pro Plan ($15/month):

• Custom disclaimer header
• Full disclaimer editing capability (after accepting legal consent)

Subscription cancellation: Available at any time through the Shopify Admin panel. After cancellation, the Pro plan remains active until the end of the paid billing period.

8. Merchant Responsibility

As a Shopify store owner, you are responsible for:

• Correct product category mapping: Selecting the appropriate HS category for each product type in the admin panel
• Customer communication: Informing customers that calculations are estimates
• Legal compliance: Adhering to customs and tax regulations in destination countries
• Custom disclaimer (Pro Plan): If you edit the disclaimer text, you take full legal responsibility for communication with the end customer
• Statement on Origin (Rules of Origin): The App assumes that goods originate from the UK/EU, which may result in zero or reduced duty rates under the UK-EU Trade and Cooperation Agreement. It is your responsibility as the merchant to include a valid "Statement on Origin" on commercial invoices when shipping goods. Failure to provide this statement may result in customs authorities applying standard duty rates, even if the App calculated zero duty. The App does not generate or validate Statements on Origin.

9. Data and Privacy

Details regarding data collection and processing can be found in our Privacy Policy.

The App is GDPR compliant. Data is stored in Supabase (region: Ireland, EU).

The App processes data strictly required by Shopify to function. We implement mandatory GDPR webhooks for data erasure requests:

• customers/redact - Customer data deletion request
• customers/data_request - Customer data access request
• shop/redact - Shop data deletion after app uninstallation

These webhooks ensure compliance with GDPR Article 17 (Right to Erasure) and Article 15 (Right of Access).

10. Limitation of Liability

Maximum liability is limited to the amount of fees paid by the merchant in the last 3 months.

11. Changes to Terms

We reserve the right to modify these Terms at any time. We will notify merchants of significant changes via email or notification in the admin panel.

Continued use of the App after changes are made constitutes acceptance of the new terms.

12. Governing Law

These Terms are governed by the laws of Poland. In case of disputes, the courts in Poland have jurisdiction (region according to business location).
