Terms of Service

These terms are between the Shopify merchant using Tunnelbox Downloads and Quantum Tunnel (“we” or “us”). By installing or using the app, you accept these terms on behalf of the store you are authorised to represent. Questions can be sent to support@quantumtunnel.foundation.

Effective date: 14 November 2026

1. Service and setup

The app attaches hosted files or external links to existing Shopify products and variants, individually or by CSV/API. Paid orders with linked digital items receive an app download page. You must configure a buyer-facing entry point: add the Digital Downloads block to the thank-you and/or order-status page, add the provided snippet to Shopify’s order confirmation notification, or share the private buyer link from the order in the app. No separate Quantum Tunnel login is needed.

App-generated delivery email requires a configured SMTP transport and sender address and must be enabled. It is not available when Settings reports that email sending is unconfigured. Shopify notification email is a separate merchant-configured option, not an automatic fallback. Access checks use payment, file entitlement and the merchant’s settings. Optional rules include download limits, expiry, manual disabling/restoration, revocation when all digital items are refunded or the order is cancelled, and automatic digital-item fulfillment.

2. Merchant responsibilities

You are the seller to your buyers and are responsible for your products, rights to distribute each file/link, taxes, refunds, consumer-law obligations, privacy notices and lawful processing of buyer data. Verify product/variant mappings and delivery entry points before selling. Keep original copies of uploaded files. Do not upload unnecessary personal information. Protect private buyer links and any API keys you create; an order link grants access to its holder subject to the app’s rules.

You instruct Quantum Tunnel to process the order, customer and delivery records described in the Privacy Policy only to provide purchased-file access, enforce your settings and handle related support. You remain responsible for lawful instructions and required buyer notices. We do not use these records for unrelated marketing or profiling. Access is restricted to authorised service operations; assistance with data requests and deletion follows the policy and support procedure. Contact support about provider, transfer, security or processing terms before supplying data subject to additional contractual requirements.

3. Hosted files and external links

Hosted files are stored privately and delivered through short-lived signed file URLs after app access checks. External files remain on the host you select; the app stores the URL and redirects buyers to it. You are responsible for that host’s content, availability, permissions and privacy practices. We do not host, scan or verify external file contents. Prefer HTTPS links.

Download limits count allowed requests through the app, including external redirects, not completed transfers. Limits, expiry and revocation cannot recall downloaded copies or invalidate an external URL already obtained. Deleting a library file removes it from existing buyer entitlements as well as future product mappings.

4. Plans and billing

Starter is US$5 per month for 100 files and 5 GiB hosted storage; Growth is US$10 per month for 500 files and 25 GiB; Pro is US$20 per month for 2,000 files and 100 GiB. All plans include all app features and a 14-day trial, subject to Shopify’s trial eligibility and approval terms. External links count toward the file limit but do not use hosted-file storage. There are no usage-based overage charges; adding content beyond capacity requires freeing space or changing plan.

Shopify displays the applicable price and terms before approval and handles subscription billing. Manage your plan in the app’s Plans page through Shopify. Uninstalling ends use of the app; it does not reverse charges already incurred. For charge questions or refund requests, contact support@quantumtunnel.foundation. Mandatory legal rights are not limited by these terms.

5. Acceptable use

• Do not distribute unlawful, malicious, deceptive or infringing content.
• Do not use the app as a general-purpose file-sharing service unrelated to your store’s products.
• Do not bypass access controls or attempt to reach another store’s files or data.
• Do not disrupt or overload the service or resell it without permission.

6. Availability and changes

The app depends on Shopify, hosting, storage and, where configured, email services. We do not guarantee uninterrupted operation, a particular processing time or email inbox delivery. Service or API changes can affect features. Where practical, we will give notice of planned material changes. You should maintain a way to assist buyers if automated delivery is delayed.

7. Ending use and data

You may uninstall through Shopify Admin. Once the uninstall event is processed, app-mediated downloads stop; content/order records remain until the applicable Shopify redaction process or an earlier deletion request. A retained external URL or already downloaded copy is not revoked by uninstall. See the Privacy Policy for the data retained, logging and deletion scope. Remove the app’s blocks and notification snippet when ending use, and plan how to support past buyers. Access may be suspended for abuse, security risks or breach of these terms.

8. Liability

To the maximum extent permitted by law, the app is provided “as is”. We are not liable for indirect or consequential loss, lost profits, lost sales, or loss of files or access records. Total liability for a claim is limited to the amount you paid for the app in the twelve months before the event giving rise to it. Nothing here excludes liability or rights that cannot lawfully be excluded.

9. Contact and updated terms

Contact support@quantumtunnel.foundation about these terms. The effective date above changes when these terms change. Continuing to use the app after revised terms take effect means you accept them, subject to any rights required by applicable law.
