Effective date: 17 July 2026
These Terms of Service (Terms) govern a merchant’s installation and use of
CheckoutControl (the App), provided by Péter Kiss, a self-employed sole
trader (autónomo) established in Spain, trading as 8DIGITS Digital Marketing
(we, uso our). By installing or using the App, the
merchant agrees to these Terms.
1. Eligibility and authority
The merchant confirms that they can enter into these Terms, have authority to
manage the connected Shopify store, and will use the App only for lawful
business purposes. If the App is installed for an organization, that
organization is the contracting merchant.
2. The service
CheckoutControl lets merchants configure rules that can hide, rename, or
reorder eligible payment and delivery options and can add a fixed or percentage
cash-on-delivery fee using Shopify Functions. It also provides an optional
cart-page COD selector theme app block.
The following v1 limitations are material:
- The cart selector is a cart-page theme block. Cart-drawer compatibility is
not included. - CART detection is the supported path for eligible non-Plus stores.
- CHECKOUT_UI mode depends on Shopify plan and extension eligibility and should
be treated as an optional plan-dependent path. - COD matching depends on the runtime payment names or handles configured by
the merchant. If no configured COD method matches, the App is designed to
fail open rather than hide every payment method. - A valid active supporting Shopify product variant is required for COD fees.
Shopify controls the platform, checkout, APIs, Function availability, plan
eligibility, and theme behavior. Shopify changes can affect App functionality.
3. Merchant responsibilities
The merchant must:
- Configure and test rules, COD aliases, fee values, the supporting fee
variant, and the theme block before using them with buyers. - Verify prices, tax treatment, currency behavior, disclosures, payment and
delivery availability, and legal compliance for every market served. - Maintain an eligible Shopify plan, compatible theme, valid Shopify account,
and required permissions. - Keep account credentials secure and promptly report suspected unauthorized
access. - Avoid using the App to discriminate unlawfully, mislead buyers, interfere
with checkout availability, or violate Shopify’s terms or applicable law. - Maintain required buyer-facing notices, consents, terms, and privacy
disclosures.
The merchant remains responsible for store operations, buyer contracts,
fulfilment, taxes, refunds, chargebacks, and the consequences of its rules.
4. Fees and billing
The App costs €4.99 per month and includes a seven-day trial. The
stated price excludes applicable taxes, which may be added where required.
Charges are created and managed through Shopify Billing. We do not collect
payment-card details for App fees. The merchant may cancel at any time, with
cancellation taking effect at the end of the current monthly billing period.
Fees are not prorated or refunded except where a refund, credit, or other remedy is
required by applicable law or Shopify’s billing rules. We will give at least 30
days’ notice of price changes. These terms must remain aligned with the final
Shopify App Store listing and billing configuration.
5. Acceptable use
The merchant must not reverse engineer the App except where law does not permit
that restriction; bypass access controls; introduce malicious code; overload or
probe the service; use the App to violate another person’s rights; resell the
App without permission; or use it contrary to Shopify’s policies.
6. Data and privacy
Our processing of personal information is described in the CheckoutControl
Privacy Policy at https://8digits.es/checkoutcontrol-privacy-policy/. The merchant authorizes us and
our service providers to process information as needed to provide the App and
is responsible for its own instructions and legal basis for buyer-data
processing.
7. Intellectual property and feedback
We and our licensors retain all rights in the App, documentation, branding, and
related technology, including its code and features. During an active
subscription, we grant the merchant a limited, non-exclusive,
non-transferable right to use the App for its internal business purposes in
accordance with these Terms. The merchant must not copy, modify, redistribute,
sell, sublicense, or create derivative works from the App except where
applicable law does not permit that restriction.
The merchant retains its rights in its Shopify store data, customer
information, product descriptions, images, store content, and rule
configuration. The merchant grants us and our service providers only the
limited rights needed to operate, secure, and support the App. Feedback may be
used without restriction or payment, provided we do not identify the merchant
publicly without permission.
8. Availability, support, and changes
Support is provided under the CheckoutControl Support Policy at
https://8digits.es/checkoutcontrol-support/. No service-level agreement or guaranteed response or uptime commitment
applies unless we agree to one in writing. We may maintain, secure, change, or
discontinue features, and will provide notice when required or reasonably
practicable.
9. Third-party services
The App depends on Shopify and Railway and may link to or interoperate with other
merchant-selected services. Third-party terms and privacy policies apply to
those services. We are not responsible for a third party’s independent acts,
outages, or changes.
10. Confidentiality
Each party will protect the other’s non-public confidential information using
reasonable care and use it only to perform these Terms, except where disclosure
is authorized or legally required. Information is not confidential if it is
public without breach, independently developed, or lawfully received without a
confidentiality duty.
11. Suspension and termination
The merchant may stop using the App and uninstall it at any time, subject to
outstanding Shopify charges. We may suspend or terminate access for material
breach, security risk, unlawful use, non-payment, platform requirements, or
discontinuation of the service. Where practicable, we will provide notice and a
reasonable opportunity to cure.
Upon uninstall, the current App deletes its active shop configuration and
sessions. Log, backup, support, and legally required retention follow the
Privacy Policy. Sections that by nature should survive termination will do so.
12. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE APP IS PROVIDED “AS IS” AND “AS
AVAILABLE.” WE DISCLAIM IMPLIED WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT
THE APP OR SHOPIFY WILL BE UNINTERRUPTED, ERROR-FREE, OR SUITABLE FOR EVERY
STORE, THEME, MARKET, OR LEGAL REQUIREMENT. NOTHING IN THESE TERMS EXCLUDES A
RIGHT OR WARRANTY THAT CANNOT LAWFULLY BE EXCLUDED.
13. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW:
- OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE APP OR THESE
TERMS WILL NOT EXCEED THE APP FEES ACTUALLY PAID BY THE MERCHANT DURING THE 12
MONTHS IMMEDIATELY BEFORE THE EVENT GIVING RISE TO THE CLAIM. - WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL,
EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, BUSINESS
OPPORTUNITIES, GOODWILL, OR THE COST OF SUBSTITUTE SERVICES. - WE WILL NOT BE LIABLE FOR DATA LOSS OR CORRUPTION, SERVICE INTERRUPTION,
MAINTENANCE, SHOPIFY PLATFORM CHANGES OR OUTAGES, OR ACTS OR OMISSIONS OF
THIRD-PARTY SERVICES, EXCEPT TO THE EXTENT THE LIABILITY CANNOT LAWFULLY BE
EXCLUDED.
The merchant is responsible for maintaining backups available through Shopify
or its other systems and for testing whether the App, its rules, and its
configuration meet the merchant’s needs before live use. We will provide
reasonable troubleshooting assistance for failures involving Shopify or other
dependencies, but we do not control those services.
These limitations apply regardless of the legal theory of the claim and even
if a remedy fails of its essential purpose. They do not exclude or limit
liability for fraud, wilful misconduct, gross negligence, death or personal
injury caused by negligence, or any warranty, statutory right, data-protection
obligation, or other liability that applicable law does not permit the parties
to exclude or limit.
14. Indemnity
These Terms do not create a contractual indemnity obligation for either party.
This does not limit any claim or remedy otherwise available under applicable
law.
15. Governing law and disputes
These Terms are governed by the laws of Spain, without regard to
conflict-of-law rules. Disputes will be submitted to the courts having
jurisdiction under applicable procedural law. Nothing in these Terms deprives a
party of any governing-law protection, mandatory venue, or other right that
cannot lawfully be waived.
16. General
These Terms, the Privacy Policy, and any written order terms are the agreement
about the App. If a provision is unenforceable, the remainder continues. A
waiver must be explicit. The merchant may not assign these Terms without our
consent; we may assign them as part of a reorganization, financing, or transfer
of the App, subject to applicable law. Electronic notices and signatures are
permitted.
