By installing, subscribing to, accessing, or using ParcelLoop, you agree to these Terms.
1. About ParcelLoop
ParcelLoop is an independent software integration that connects online store orders with Royal Mail Click & Drop. Depending on your configuration and available third party functionality, ParcelLoop may send order and shipment information to Royal Mail Click & Drop, apply configured parcel weights and shipping services, retrieve or receive tracking information, and update order fulfilment information.
ParcelLoop is an independent integration and is not affiliated with or endorsed by Royal Mail.
2. Eligibility and account responsibility
You must have authority to install and use ParcelLoop for the relevant business or website.
You are responsible for:
- maintaining your own Wix and Royal Mail accounts;
- ensuring that the information and settings you provide are accurate;
- keeping your account credentials and API credentials secure;
- ensuring that your use of ParcelLoop, Wix, Royal Mail Click & Drop, and any shipping services complies with applicable law and the terms of those services.
You must not use ParcelLoop for unlawful, fraudulent, abusive, or unauthorised purposes.
3. Third party services
ParcelLoop depends on third party services, including Wix and Royal Mail Click & Drop.
Those services are operated independently and may change, suspend, restrict, or discontinue features without our control. Their own terms, policies, service availability, pricing, account requirements, and technical limitations also apply to you.
We are not responsible for outages, delays, errors, rejected shipments, service changes, account restrictions, or other failures caused by third party services.
4. Subscription, pricing and trial
ParcelLoop is offered as a paid subscription through the Wix App Market.
The current standard plan is:
- Monthly: USD $14.99
- Annual: USD $149.99
- Free trial: 14 days
- Order limit: No ParcelLoop imposed order limit on the paid plan
Any price displayed to you at checkout is the price that applies to your purchase.
Wix handles checkout, subscription billing, invoices, payment processing, and related payment administration. We do not receive or store your full payment card details.
Taxes, currency conversion, billing dates, renewal mechanics, refunds, and payment handling may be subject to Wix's applicable terms and checkout process and to applicable law.
5. Automatic renewal and cancellation
Unless cancelled, a recurring ParcelLoop subscription may renew automatically through Wix according to the billing period you selected.
You can cancel through the subscription management options made available by Wix. Cancellation normally stops future renewal; access may continue until the end of the period already paid for, subject to Wix's billing rules and applicable law.
Ending or cancelling a subscription does not automatically cancel postage, shipping labels, Royal Mail services, or charges already created through your Royal Mail account.
6. Your Royal Mail configuration and shipping decisions
You are responsible for checking that your Royal Mail account, shipping services, parcel formats, weights, service mappings, customs information, addresses, and other shipping settings are correct for your business.
ParcelLoop can automate configured values, but you remain responsible for the shipping choices made using your accounts.
You should review your configuration before enabling live automation and after making changes to products, packaging, shipping methods, or Royal Mail services.
7. Order and tracking automation
ParcelLoop is designed to reduce manual order processing. However, automated integrations can occasionally fail or produce errors because of missing data, invalid addresses, unavailable services, third party outages, API changes, rate limits, or configuration issues.
You are responsible for monitoring failed or pending orders and taking reasonable action where the app indicates that attention is required.
We do not guarantee that every order will be accepted by Royal Mail, that a particular service will always be available, or that tracking information will be returned within a particular time.
8. Acceptable use
You must not:
- attempt to bypass security or access controls;
- interfere with ParcelLoop or its infrastructure;
- reverse engineer or exploit the service except where the law expressly permits;
- use ParcelLoop to transmit malicious code;
- use another person's account or credentials without authority;
- use the service in a way that may damage our systems or third party services.
We may suspend access where reasonably necessary to protect the service, users, third parties, or our legal interests.
9. Intellectual property
ParcelLoop, its software, interface, original branding, documentation, and related intellectual property are owned by or licensed to Kapstone Holdings Limited.
You receive a limited, non exclusive, non transferable right to use ParcelLoop for your own business purposes while your authorised access remains active.
Royal Mail, Click & Drop, Wix, and other third party names, marks, and services remain the property of their respective owners.
10. Availability and changes
We may update, improve, modify, or discontinue parts of ParcelLoop from time to time.
We aim to provide a reliable service, but we do not guarantee uninterrupted or error free availability.
Where a material change affects paid functionality, we will take reasonable steps to communicate it through the app, by email, or through another appropriate channel.
11. Support
Support is available at support@rocklabsystems.com.
We may ask for diagnostic information reasonably required to investigate an issue. Please do not send passwords or full payment card information to support.
12. Data protection and privacy
Our handling of personal data is described in the ParcelLoop Privacy Policy.
Where ParcelLoop processes customer order information on your behalf for the purpose of providing the service, you remain responsible for ensuring that you have an appropriate lawful basis and privacy information in place for your customers.
13. Disclaimer
ParcelLoop is provided on an "as available" basis.
To the maximum extent permitted by law, we do not warrant that the service will always be uninterrupted, error free, or compatible with every future version or configuration of a third party service.
Nothing in these Terms excludes rights or remedies that cannot lawfully be excluded.
14. Limitation of liability
Nothing in these Terms limits or excludes liability where doing so would be unlawful, including liability for fraud or fraudulent misrepresentation.
Subject to the above, to the maximum extent permitted by law:
- we are not liable for indirect, incidental, special, or consequential loss;
- we are not liable for loss of profit, revenue, business opportunity, goodwill, or anticipated savings arising from use of ParcelLoop;
- we are not liable for losses caused by incorrect shipping configuration, third party outages, Royal Mail service decisions, Wix service decisions, or information supplied by you;
- our total aggregate liability arising out of ParcelLoop in any 12 month period will not exceed the total subscription fees paid for ParcelLoop in that same 12 month period.
This section does not affect any statutory rights that cannot lawfully be limited.
15. Indemnity
To the extent permitted by law, you are responsible for losses, claims, or costs arising from your unlawful use of ParcelLoop, your unauthorised use of another person's data or account, or your breach of these Terms.
16. Termination
You may stop using ParcelLoop at any time and may cancel your subscription through Wix.
We may suspend or terminate access where you materially breach these Terms, misuse the service, create a security risk, or where continued provision of the service would be unlawful.
On termination, your right to use ParcelLoop ends, subject to any access period already paid for and any retention required for legal, security, accounting, or legitimate operational purposes.
17. Changes to these Terms
We may update these Terms from time to time. The latest version will be published at the public Terms URL.
If a change is material, we will take reasonable steps to notify affected users.
Continued use after an updated version takes effect constitutes acceptance of the updated Terms where permitted by law.
18. Governing law and jurisdiction
These Terms are governed by the laws of the Isle of Man.
Subject to any mandatory rights that apply to you, the courts of the Isle of Man have jurisdiction in relation to disputes arising from these Terms or ParcelLoop.
