Terms of Use

Last updated: 21/09/2026

Dyno Bulk Discount Codes Terms of Use

These Terms govern business use of Dyno Bulk Discount Codes, also listed as Bulk Discount Codes Generator on the Shopify App Store (the “App”). They describe your rights and responsibilities and those of UAB Xantho (“we”, “us” or “our”). “You” means the merchant business using the App.

1. Provider and acceptance

The App is provided by UAB Xantho, a Lithuanian company. Company registration number: 304751741. VAT number: LT100011513814. Registered office: Partizanų g. 61-806, LT-49282 Kaunas, Lithuania. Email: dynoapp@xantho.lt. Phone: +370 633 57553.

By accepting these Terms through the App, or using the App after these Terms have been clearly presented to you with notice that use constitutes acceptance, you agree to them. You must have authority to bind the merchant business and manage the relevant Shopify store. The App is intended for business use. If you do not agree, do not use the App and cancel any subscription. These Terms do not apply retroactively to use before their valid acceptance.

2. The service and Shopify

The App helps merchants generate unique discount codes in bulk, import and export codes in CSV format, add codes to discount sets, and use supported discount combinations. Available functions depend on the selected plan, Shopify capabilities and the App interface. The App does not guarantee campaign revenue, prevention of code sharing, or elimination of coupon abuse.

UAB Xantho is solely responsible for the App, its development, marketing, distribution, support and handling of merchant data. Shopify is not a party to these Terms and is not liable for App faults or harm caused by installation or use. Except where Shopify expressly states otherwise, Shopify does not provide installation or usage assistance. Responsibility for liabilities arising from your access to or use of the App rests with us, not Shopify, subject to these Terms and applicable law. Your separate agreement with Shopify continues to apply.

3. Access and permitted use

During your subscription or permitted free access, we grant you a limited, nonexclusive right to use the App for your business on authorized Shopify stores. You are responsible for authorized staff, account security and permissions. Notify us promptly if you suspect unauthorized use.

You must not use the App unlawfully; upload malicious code; interfere with security or service operation; bypass billing or technical restrictions; access other merchants’ data without authorization; or copy, resell or reverse engineer the App except where applicable law permits. Nothing here prohibits lawful competition or restricts your choice of customers, suppliers or other apps.

4. Discount settings and campaign checks

You control your promotions and are responsible for choosing and checking discount amounts, eligible products and customers, minimum purchase requirements, usage limits, start and expiry dates, time zones, shipping conditions and combinations with other discounts. You must have the necessary rights to imported codes and other submitted material.

Before distributing codes or launching a campaign, review the generation or import results and test representative codes in your Shopify checkout. Do not assume a batch has completed successfully solely because you submitted it. Review errors, partial completion and potential duplicates before retrying a request.

You are responsible for lawful advertising, customer communications and fulfilment of your promotions. Keep copies of exported codes and campaign records where needed. Shopify rules, other apps and subsequent store changes can affect redemption. These responsibilities do not exclude our liability for our own breach where applicable law makes us responsible.

5. Plans billing and cancellation

The price, currency, billing interval, included features, trial period and any usage limits shown when you approve a plan form part of your subscription. Charges are processed through Shopify unless a separate written agreement states otherwise. Applicable taxes may be added. Each store requires its own subscription unless expressly included in your plan.

Paid subscriptions renew automatically at the approved interval until cancelled. Where an approved subscription includes a trial, charging starts when that trial ends unless you cancel beforehand, as explained in the approval screen. Free access or promotional offers apply only on their stated conditions.

You can cancel by uninstalling the App through Shopify or using an available subscription cancellation control. Simply stopping use does not cancel billing. Charges already incurred may appear on a later Shopify invoice. Cancellation stops future recurring charges but does not erase amounts properly incurred before cancellation.

Except where required by law, expressly promised in your plan, or provided below, fees for a started billing period are nonrefundable and unused time is not automatically credited. Contact support about duplicate or incorrect charges or significant service failures; we will investigate and make any refund or correction that is due. Any discretionary refund must be confirmed by us.

Price changes apply only to new subscriptions. Existing subscriptions retain their current price while they remain active. If you cancel and later subscribe again, the pricing shown when you approve the new subscription will apply.

6. Availability changes and support

We will use reasonable care and skill in providing the App and reasonable efforts to investigate reported defects. Support is available through the App’s support channel and the contact address above. No guaranteed response time, uptime commitment or service credit applies unless separately agreed in writing.

Maintenance, security incidents, connectivity problems, Shopify outages, API limits or third-party changes may interrupt or delay operation. We may update the App to fix defects, maintain compatibility or improve functionality. We will give reasonable advance notice of changes that materially reduce paid core functionality, unless urgent security or legal requirements prevent it. If such a reduction materially prevents your intended use, you may cancel and request a proportionate refund of prepaid fees for the affected unused period.

7. Data privacy and confidentiality

The App accesses authorized store and owner information, product and collection information, and discount data to operate its features. The data we store may include merchant contact details, discount identifiers and titles, generation counts, status, and timestamps. We do not access or store personal data about your store’s customers. Our Privacy Policy at https://www.xantho.lt/privacy-policy explains data practices and service providers. Permissions shown during installation identify the access requested.

The app does not have access to order, customer, or payment data. If access to any of this data becomes necessary for the app’s core functionality in the future, we will request your explicit approval before accessing it.

You retain your rights in your store information and discount-related data. You authorize us to access and process only the data covered by the permissions you grant, as necessary to provide the App’s services. Confidential store information must be protected and shared only as necessary with personnel and providers under appropriate obligations, or where legally required. This obligation does not cover information already lawfully public or independently obtained without a duty of confidence.

Where we process personal data on your behalf and a data processing agreement is legally required, that agreement must be put in place and governs that processing. These Terms do not replace it or waive data protection rights. You are responsible for lawful instructions and required notices for data you provide. We remain responsible for our own legal obligations.

8. Intellectual property

We and our licensors retain ownership of the App, its software, branding and documentation. These Terms give you a right to use the service, not ownership of its software. We do not claim ownership of your merchant data or your promotional content. You may use and export generated discount codes for your business, subject to applicable rights and Shopify rules.

9. Warranties and limits of liability

Except for our express commitments and obligations that cannot lawfully be excluded, the App is provided as available without further warranties. We do not warrant uninterrupted or error-free operation, compatibility with every app or configuration, or any particular commercial result.

To the extent permitted by law, we are not liable for indirect or consequential losses, including lost profits, lost opportunities or reputational loss. Our total aggregate liability arising from these Terms or the App is limited to the greater of USD 100 and the App fees you paid to us, including through Shopify, during the 12 months preceding the event giving rise to the claim. Related events are treated as one event for this limit. Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law.

10. Suspension termination and stored discounts

We may suspend access to address a material breach, unpaid charges, unlawful use or a credible security threat. Where reasonably possible, we will explain the reason and give you an opportunity to resolve the problem. Immediate action may be taken where necessary to protect people, data, systems or legal compliance.

We may terminate for an unresolved material breach after giving 14 days’ notice to remedy it, or immediately for a breach that cannot reasonably be remedied. We may discontinue the service or terminate for convenience on at least 30 days’ notice. If we terminate for convenience, we will refund prepaid fees attributable to the unused service period.

On termination, your access ends and fees already properly incurred remain due. Export needed records before cancellation. Uninstalling the App should not be assumed to deactivate or remove discounts already created in Shopify; review and disable unwanted discounts in Shopify directly.

We delete Shopify-derived merchant data within 30 days of uninstall or another applicable deletion trigger, except where law prohibits or varies that requirement. Legally required retained records remain protected. Payment obligations, confidentiality, intellectual property, liability limits and dispute provisions survive termination to the extent relevant.

11. Updates to these Terms

We may amend these Terms for changes in the service, law or business operations. We will present material changes through the App or email at least 30 days before they take effect, unless a shorter period is necessary for legal or urgent security reasons. Changes operate prospectively. We will request express acceptance where required by law. Otherwise, continued use after the notified effective date constitutes acceptance only where legally valid. You may reject changes by cancelling before they take effect.

12. Governing law and general provisions

These Terms are governed by Lithuanian law. Subject to mandatory jurisdiction rules, disputes fall within the exclusive jurisdiction of the competent courts of Lithuania. Please first contact us with a description of the issue so that we can attempt to resolve it; this does not prevent either party from seeking urgent relief or preserving a legal deadline.

These Terms, the approved plan and any separate written agreement constitute the agreement for the App. A separately signed agreement prevails where it expressly varies these Terms; an applicable data processing agreement prevails for conflicting processing provisions. Privacy notices explain processing and do not expand consent or override mandatory obligations. An invalid provision does not invalidate the rest. Failure to enforce a provision is not a waiver. Formal notices may be sent to the contact details in section 1; we may contact you at your store’s designated email address.
