Terms and Conditions

Version dated 15 September 2026 · For business customers only.

1. Seller and scope

ChangeWatch is provided by Flavian Combes, a sole trader operating under the trade name Cybersignal, 60 rue François 1er, 75008 Paris, France. SIREN: 879 536 928; SIRET: 879 536 928 00028; registered with the Paris Trade and Companies Register (RCS) under number 879 536 928. Contact: changewatch@cybersignal.fr.

These terms govern subscriptions to ChangeWatch. They apply when they have been brought to the customer’s attention and accepted before the contract is concluded. Any specific terms expressly agreed in writing take precedence over the corresponding provision of these terms.

2. Business customers only

The offer is restricted to professionals acting in the course of their business. The subscriber must have legal capacity and, when representing an organisation, authority to bind it. They must provide accurate business and billing information. Cybersignal may request the information needed to verify this status before activation.

3. Service description and sources

ChangeWatch helps monitor changes on publicly accessible web pages: product pages, public collections or categories, prices, promotions, offers, availability and delivery terms. Confirmed important changes trigger an email alert containing a source link. When no significant alert has been sent, a weekly summary reports on monitoring activity.

Alerts support decision-making. The customer must independently verify information before any important business decision. No economic outcome or competitive advantage is guaranteed.

4. Compatibility and coverage

Detection depends on the publicly accessible information on each monitored page. Compatibility and coverage are checked during setup. Dynamic structures, JavaScript-loaded content, access restrictions and anti-bot mechanisms may limit or prevent monitoring. Some collection or category pages allow only partial coverage.

The service does not guarantee compatibility with every website, complete catalogue coverage or detection of every change. False positives and missed changes may occur. A page’s compatibility may change after activation. Pages requiring authentication or the circumvention of an access control are not supported.

5. Plans and prices

Every plan includes manual setup, important change detection and email alerts. Business and Pro include priority setup and support. Checks run on a schedule and do not constitute real-time monitoring.

VAT not applicable — Article 293 B of the French General Tax Code (CGI). Plans are monthly, with no minimum commitment beyond the subscribed monthly period. No price change applies retrospectively to a period already paid for. Changes for future periods are communicated before taking effect so that the customer can decline renewal.

6. Subscription, payment and invoicing

The customer selects a plan on the website and then uses the payment page hosted by Stripe. Stripe processes the initial payment and monthly renewals. The price and billing frequency are shown before payment is confirmed. The contact form is optional for questions before subscribing; it does not constitute a payment.

Stripe processes payment data. ChangeWatch does not directly store full payment card details. Billing information must be kept up to date. An invoice is issued for the amounts due; requests concerning its receipt or correction should be sent to changewatch@cybersignal.fr.

Monthly fees are payable on subscription and on each subsequent due date. For late business payments, statutory penalties apply from the day after the payment date shown on the invoice: the applicable European Central Bank refinancing rate plus ten percentage points, under the conditions provided by law, and a fixed recovery charge of €40, subject to statutory exceptions. Additional compensation may be requested with supporting evidence where recovery costs exceed that amount.

7. Setup and start of monitoring

Payment starts the subscription and billing period; it does not automatically configure monitoring. Cybersignal manually finalises with the customer the list of URLs within the plan limit, their compatibility and coverage, email recipients and the applicable frequency. Activation is confirmed after this setup, completed within a reasonable time taking account of receipt of the necessary information. No specific deadline is guaranteed.

The customer may request a compatibility check before paying. If a difficulty is identified after subscription, Cybersignal informs the customer and seeks a suitable solution, such as a replacement public page. If the agreed service cannot be provided, the parties address the contractual and financial consequences according to the circumstances and applicable rules; this clause does not remove the customer’s remedies for non-performance.

8. Customer obligations

9. Changing pages and support

The customer may request replacement pages within their plan limit. New pages are checked for compatibility and coverage. Support requests are received at changewatch@cybersignal.fr. The priority provided for Business and Pro does not guarantee a response at a specific time or continuous support.

10. Availability and reasonable efforts

Cybersignal uses reasonable efforts to provide the service under the agreed plan, monitor its operation and address reported issues. Access to third-party pages, networks, email deliverability, providers and maintenance may affect checks and notifications. Uninterrupted or error-free operation is not guaranteed. The absence of an alert does not prove the absence of a change.

11. Cancellation and its effects

The customer may request cancellation at any time by emailing changewatch@cybersignal.fr, identifying the subscription concerned. The date the request is received determines when future renewals stop: a request received before the next due date prevents that renewal. Cybersignal confirms receipt and the end date.

Unless otherwise agreed or there is a legal ground for suspension, the service remains available until the end of the paid period. Paid periods that have already begun are not automatically refunded, including on a pro-rata basis, unless required by law or expressly agreed. After the end date, the associated checks and notifications stop. Data is then handled according to the privacy policy and applicable retention obligations.

12. Non-payment and breaches

If payment fails, Cybersignal informs the customer and allows a reasonable time to resolve the issue before suspending or stopping monitoring. In the event of a contractual breach, a request to remedy it sets out the facts and the intended consequences. If the breach continues after a reasonable period, the contract may be terminated under the conditions provided by law.

A proportionate suspension may take effect immediately in the event of manifestly unlawful use or a security risk requiring immediate action; the customer is informed as soon as possible, unless prohibited by law.

13. Intellectual property

ChangeWatch software, design, text and trademarks remain the property of Cybersignal or their respective owners. The subscription permits business use of the service for its duration, without transferring ownership. Content on monitored websites remains the property of its owners. Access to an alert does not grant rights to reproduce or exploit competitor content beyond what the law permits.

14. Confidentiality

Each party protects the confidentiality of non-public information received in the business relationship and uses it only for the purposes of that relationship. Disclosure is limited to persons and providers who need it, with appropriate protection, or where required by law. This obligation does not cover information lawfully made public or legitimately obtained from another source; it continues after the contract ends for as long as the information remains confidential.

15. Liability

Each party is responsible for direct and foreseeable loss caused by a breach attributable to it, under applicable law. The service’s role as a monitoring aid and its stated limitations are taken into account when assessing Cybersignal’s obligations; they do not constitute a general exclusion of liability.

Cybersignal is not responsible for loss resulting exclusively from the customer’s unlawful use or an external cause not attributable to Cybersignal. No clause limits liability where the law prohibits it, notably in the event of gross negligence or wilful misconduct, and no clause deprives an essential obligation of its substance. The customer’s business decisions do not release Cybersignal from responsibility for its own breaches.

16. Force majeure

The consequences of a force majeure event are governed by Article 1218 of the French Civil Code. A network or provider outage does not automatically qualify as force majeure: the legal conditions must be met. The affected party informs the other party and takes reasonable steps to limit the event’s effects.

17. Communications, evidence and logs

Stripe confirmations, invoices, emails and lawfully retained technical logs may help establish subscription, payments, requests and service performance. They do not constitute conclusive evidence that cannot be challenged: each party remains entitled to provide contrary evidence. Retention periods and access remain subject to the privacy policy and the law.

18. Personal data

Processing is described in the privacy policy. The customer must ensure that the data and URLs they provide are lawful. If a service involves processing personal data on the customer’s behalf that requires a specific agreement, the parties define their roles and enter into the required agreement before that processing begins.

19. Applicable law and disputes

The contract is governed by French law, subject to applicable mandatory rules. In the event of a difficulty, the parties may seek an amicable solution by contacting changewatch@cybersignal.fr, without preventing legal action or urgent measures.

If no agreement is reached, the dispute falls within the jurisdiction of the courts competent under the ordinary rules applicable to the nature of the dispute and the parties’ status. Exclusive jurisdiction of the Paris Commercial Court is not imposed on all business customers.
