Merchant terms of service

Parties and apps covered

Parallel Studio LLC (“Parallel Studio,” “we,” “us,” or “our”) is a Minnesota limited liability company. These terms are an agreement between Parallel Studio and the Shopify merchant, agency, or other organization that installs or uses an app we publish (“you” or “merchant”).

These terms cover ChangeProof, Makewright, and Deltaproof as those products are provided from time to time. A product may publish additional terms where its workflow needs more detail. Additional product terms apply together with this document. If they conflict, the product-specific terms control for that product.

These terms do not replace Shopify's terms, a merchant's own storefront terms, or any separate written agreement we sign with you. Installing an app, authorizing Shopify billing, or continuing to use an app after we publish an update means you accept the current version of these terms.

What we provide

We provide each app as shipped, on an as-provided basis. Features, scopes, and operating boundaries may differ by product. In particular:

• ChangeProof records supported store-configuration changes with explicit source confidence. When Shopify cannot identify an actor, the ledger may say unknown. A rollback is applied only after a merchant-approved preview; if the store has changed, the write is refused.
• Makewright helps merchants sell configurable and made-to-order products. The merchant remains responsible for catalog content, pricing rules, quotes, and customer relationships.
• Deltaproof measures public catalog, policy, and anonymous cart surfaces. It does not open checkout, submit payment, or provide a buyer identity.

We do not promise that every Shopify event will be captured, that a report or receipt is complete for every store, or that an app will remain available without interruption. We do not sell professional services, retainers, or guaranteed outcomes under these terms.

Subscriptions and Shopify Billing

Paid plans, where offered, are billed through Shopify Billing. By choosing a paid plan you authorize Shopify to charge the fees shown in Shopify Admin for that plan, on the interval Shopify displays, plus any taxes Shopify collects.

Plan changes and complimentary access

A complimentary, founding, trial, or other promotional grant does not change the terms that apply to paid tiers. It does not create a right to keep unpaid access, a discounted rate, or features that a later paid plan may include. When a complimentary period ends, continued use of a paid tier requires an active Shopify subscription for that tier.

Fees, refunds, and billing records

Listed prices are monthly unless Shopify shows otherwise. We do not hide metered overage behind a published plan. Shopify, not Parallel Studio, processes the charge and keeps the billing record. Refunds, chargebacks, tax invoices, and payment-method updates are handled through Shopify's billing tools and policies, except where law requires us to act directly.

We may change published prices or plan features for future billing periods. Changes take effect as shown in Shopify Admin or on the product page when you next approve or continue a charge. We do not commit to a service-level agreement, uptime credit, or usage cap beyond what a given plan states in the app or listing.

Acceptable use

You may use the apps only for your legitimate Shopify store operations. You agree not to:

• use an app to break the law, Shopify's terms, or another person's rights;
• probe, overload, scrape, or interfere with an app, its providers, or other merchants except through documented product features;
• circumvent fail-closed checks, preview locks, receipt gates, or other safety boundaries;
• submit or grant access to personal information the product does not need, including payment-card data, buyer checkout objects, or credentials we ask you not to send;
• resell, sublicense, or provide the app as a service to unaffiliated stores except through a published agency or portfolio feature; or
• misrepresent a report, receipt, score, or ledger entry as covering more than the product measured.

We may suspend or limit access when we reasonably believe these rules, Shopify platform rules, or applicable law have been broken, or when a charge fails.

Data handling

How each app processes information, who our providers are, how long data is kept, and the choices available to merchants and other affected people are described in the Parallel Studio app privacy policy. These terms do not repeat or replace that policy. If a privacy question arises, the privacy policy controls for data-handling practices.

You are responsible for deciding what information your store sends to an app and for notices you owe your own customers. For Makewright quote submissions, the merchant is generally the controller of shopper information; shoppers should usually contact the merchant first.

Warranty disclaimer

The apps and related materials are provided as is and as available. To the fullest extent permitted by law, we disclaim all warranties, whether express, implied, or statutory, including merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that an app will be error-free, uninterrupted, or compatible with every Shopify plan, theme, app, or custom integration. We do not warrant that evidence, scores, previews, receipts, quotes, or reports will be complete, current, or sufficient for any legal, accounting, insurance, or compliance purpose. Fail-closed behavior is a product boundary, not a guarantee that every unsafe action will be stopped.

Limitation of liability

To the fullest extent permitted by law, Parallel Studio and its members, officers, contractors, and providers are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, business interruption, or replacement costs, even if we were told those losses were possible.

Our total liability for all claims arising out of these terms or an app is limited to the fees you paid to us through Shopify Billing for that app in the 12 months before the claim, or one hundred U.S. dollars if you paid no such fees. Some jurisdictions do not allow certain limits; in those places, our liability is limited to the maximum extent the law allows.

Shopify, Cloudflare, Railway, Supabase, Resend, and other providers act under their own terms. We are not responsible for Shopify platform changes, outages, or data Shopify does not make available to an app.

Termination and uninstall

You may stop using an app at any time by uninstalling it from Shopify Admin. Uninstalling ends the paid subscription Shopify attaches to that install, subject to Shopify's billing rules for the current period.

We may suspend or end access if you breach these terms, if Shopify requires it, if billing fails, or if we discontinue a product. We will give notice when we reasonably can. On uninstall or shop redaction, access credentials are revoked or purged as described in the privacy policy. Some narrowly required security or legal records may remain.

Sections that by their nature should survive—including acceptable use, warranty disclaimer, limitation of liability, governing law, and this survival sentence—continue after the app is uninstalled.

Governing law

These terms are governed by the laws of the State of Minnesota and the United States, without regard to conflict-of-law rules. The parties agree that courts located in Minnesota have exclusive jurisdiction over disputes arising from these terms or the apps, except that either party may seek injunctive relief in any court of competent jurisdiction to protect intellectual property or confidential information.

If a court finds a provision unenforceable, the rest of these terms still apply. A failure to enforce a provision is not a waiver.

Changes

We may update these terms as our products, providers, or legal obligations change. We will publish the revised terms with a new effective date and provide additional notice where required. Continued use after the effective date constitutes acceptance of the update.
