Terms of Service

Effective date: 29 September 2026

1. Agreement

These Terms of Service (“Terms”) govern your access to and use of krono-labs.com, including our video courses, e-books, our compliance platform CertifiOS, and our consulting engagements (together, the “Service”). The Service is operated by Krono, the trade name of a sole proprietorship based in Chennai, India (“Krono”, “we”, “us”, or “our”). By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

If you use the Service on behalf of a company or other organisation, you confirm that you are authorised to accept these Terms on its behalf.

2. Description of Service

Krono publishes paid video courses and e-books teaching hardware regulatory compliance, each bundled with downloadable resources such as templates and checklists. We operate CertifiOS, a compliance platform that helps you identify which directives, standards and requirements are likely to apply to your product and target markets. CertifiOS is provided free of charge in full, with no subscription and no paid tier. We also offer consulting engagements, described on our services page and governed by Section 6.

The Service is intended for businesses, engineers and compliance professionals.

3. Important Disclaimer — Not Legal Advice, Not Certification

Course content, e-book content, downloadable templates and the output of the free compliance platform are provided for educational and informational purposes only. They do not constitute legal advice, regulatory advice, or a guarantee of regulatory compliance.

Regulatory requirements vary by product, market and jurisdiction, and change over time. You are solely responsible for ensuring that your products meet all applicable legal requirements. Before relying on course content, template documents or platform output to make compliance decisions, you should engage a qualified compliance professional, notified body or legal counsel as your situation requires.

Consulting engagements provide regulatory and engineering advice and project support based on professional experience. Krono is not a law firm, a notified body, a UK approved body, a telecommunication certification body, or an accredited testing laboratory, and does not issue certificates, test reports, or conformity decisions. Where your product requires testing or third-party assessment, that work is carried out by independent accredited bodies, which make their own decisions.

Krono makes no representation or warranty that any course, template, platform output or consulting engagement will result in any product being tested successfully, certified, approved, or accepted by any regulatory authority, notified body, customs authority, market surveillance authority or marketplace. You remain the manufacturer or responsible economic operator for your product, and you are responsible for every declaration and submission made in your name.

4. Accounts and Access

You can use the free compliance platform without an account. When you purchase a course or book, an account is automatically created using the email address you provide at checkout, and you are granted access to that content. You are responsible for keeping your login credentials confidential and for all activity under your account.

You must provide accurate information and must not impersonate any person or entity or misrepresent your affiliation with any organisation.

We may suspend or terminate accounts that violate these Terms or are associated with fraudulent activity.

5. Courses and Books: Payments, Access and Refunds

Courses, books, bundles and Vault purchases are sold through Paddle, which acts as the reseller and merchant of record for those orders and handles the applicable sales taxes. By completing a purchase you also agree to Paddle's terms. Prices are shown exclusive of applicable taxes unless otherwise stated.

Companion books: Where a course has a companion e-book, purchasing the course gives you free access to that book. The book has no separate cash value.

Access: Purchased courses and books remain accessible in your account for as long as the Service is offered and your account remains in good standing. Course videos are streamed, books are read in the browser or downloaded as EPUB where offered, and downloadable course resources are provided through time-limited links. We will make reasonable efforts to restore access promptly if a technical issue interrupts it.

Refunds: You may request a refund on a course, book or bundle within 14 days of purchase, provided you have not completed more than 30% of a course's lessons or downloaded the majority of its included resources. Send refund requests to [email protected] with your payment email and order reference. This does not affect any statutory rights you have under applicable consumer protection law.

6. Consulting Engagements

6.1 Scope and price

Prices on our services page are indicative starting points. For each engagement we confirm a written scope and a fixed fee. No work begins and nothing is charged until you have accepted both in writing. The fee changes only if the scope changes, and any change is agreed in writing first.

6.2 Your responsibilities

You agree to provide accurate and complete information about your product, and to supply documents, samples, decisions and access to your team when the engagement needs them. Our advice relies on what you tell us. Where information is late, incomplete or inaccurate, timelines move accordingly and we are not responsible for the consequences. Decisions about your product, including whether to follow our advice, remain yours.

6.3 Third parties

Test laboratories, notified and approved bodies, certification bodies, authorised representatives and similar providers are engaged by you, contract with you, and are paid by you directly. Their fees are not part of our fee. We may recommend and coordinate with them, but we do not control their timelines, results or decisions. We take no commission or referral fee from any of them.

6.4 Invoices and payment

Consulting engagements are invoiced by Krono directly and are not sold through Paddle. Invoices are issued in US dollars unless another currency is agreed, and in Indian rupees for clients in India. Indian GST is charged where it applies; services supplied to clients outside India are treated as exports where the legal conditions are met. Accepted payment methods are stated on each invoice. Transfer and bank charges on your side are yours to pay.

Unless your scope says otherwise, fees are payable as follows:

  • Compliance Assessment: 100% on acceptance of the scope.
  • Market Launch and India Market Launch: 50% on acceptance of the scope, 50% at handover.
  • Multi-Market Launch and EU Cyber Resilience Act Programme: 40% on acceptance of the scope, 30% at the midpoint milestone named in the scope, and 30% at handover.
  • Compliance Rescue and Custom Engagements: as set out in the scope.

Invoices are due within 15 days of issue. If an invoice is overdue, we may pause work until it is paid, and agreed timelines extend by the length of the pause.

6.5 Compliance Partner

Compliance Partner is a monthly engagement with a minimum term of three months. Each month is invoiced on the 1st and is due by the 15th of that month. After the minimum term, either party may end it with 30 days' written notice, and fees for the notice period remain payable. The products and markets covered are those set out in the scope.

6.6 Assessment credit

The fee for a Compliance Assessment is credited in full against a Market Launch, Multi-Market Launch, India Market Launch or EU Cyber Resilience Act Programme for the same product, if that engagement is accepted within 60 days of the assessment report.

6.7 Cancellation and refunds

You may cancel an engagement at any time by writing to us. If you cancel before any work has started, we refund everything you have paid. Once work has started, you pay for the work completed, measured against the milestones in your scope, subject to a minimum of 25% of the total engagement fee. Anything you have paid beyond that is refunded within 30 days.

We may end an engagement if an invoice remains unpaid for more than 30 days after its due date, if you do not provide the information or cooperation the engagement needs, or if continuing would require us to act unlawfully or against professional standards. In that case the same rule applies: you pay for work completed and we refund the rest.

6.8 Confidentiality

We treat all non-public information you share with us during an engagement as confidential. We use it only to deliver the engagement, and we disclose it only to third parties you have authorised (such as your chosen test lab) or where the law requires. We sign a mutual non-disclosure agreement with you once you accept the scope. Where that agreement and these Terms differ on confidentiality, the agreement prevails. These obligations continue after the engagement ends.

6.9 Your files

We receive files by email or through a sharing link you choose, and store them only on encrypted devices. We delete the files you send us within 30 days of the engagement being completed, or of the end of a Compliance Partner term. We keep our own deliverables and the correspondence of the engagement for up to three years, as a record of the advice given. Our Privacy Policy describes how we handle personal data within those files.

6.10 Deliverables

Once the related invoices are paid, you may use the deliverables of an engagement for your own products and business, including sharing them with your test labs, certification bodies, authorities and advisers. Our methods, templates, know-how and the regulatory database behind CertifiOS remain ours.

6.11 Timelines

Turnaround times and timelines are good-faith estimates, not guarantees. Much of a typical engagement depends on third parties, particularly test laboratory and certification body lead times, which are outside our control.

7. Acceptable Use

You agree not to:

  • Share your account credentials or purchased content with anyone who has not purchased access
  • Reproduce, redistribute or resell course videos, e-books or downloadable templates without our written consent
  • Attempt to circumvent payment, access controls or rate limits
  • Reverse engineer, scrape or systematically extract data from the Service, including the regulatory database behind the free compliance platform
  • Submit false or misleading information to the free compliance platform with intent to abuse or overload it
  • Use the Service in any way that violates applicable law or third-party rights

8. Intellectual Property

Krono's brand, software, course videos, e-books, downloadable templates and underlying regulatory database are the intellectual property of Krono. Purchasing a course or book grants you a personal, non-transferable licence to access and use that content for your own work; it does not transfer ownership or any right to redistribute it.

Product details and document text you enter into CertifiOS remain yours. You grant us a limited licence to store and process that information solely to generate your compliance plan, render the documents you draft, and operate the Service. CertifiOS does not accept file uploads and we do not take custody of your technical documentation through it.

Regulatory reference data (directive text, standard references, official journal citations) is drawn from publicly available official publications and is not our proprietary content.

9. Limitation of Liability

To the maximum extent permitted by applicable law, Krono shall not be liable for:

  • Any inaccuracy, incompleteness or error in course content, e-books, downloadable templates or platform output
  • Any regulatory rejection, enforcement action, recall, fine, or other consequence arising from reliance on the Service, except to the extent caused by our failure to perform a consulting engagement with reasonable skill and care
  • Any decision made or action taken by a test laboratory, notified or approved body, certification body, authority, customs service or marketplace
  • Any indirect, incidental, special, consequential or punitive damages
  • Loss of data, revenue, profits or business opportunity

For a consulting engagement, our total aggregate liability for all claims arising out of or related to that engagement shall not exceed the fees you paid us for that engagement. For a Compliance Partner engagement, this is the fees paid in the 12 months before the claim arose.

For everything else, including courses, books and the free platform, our total aggregate liability shall not exceed the amount you paid us in the 12 months before the claim arose.

Nothing in these Terms limits liability that cannot be limited under applicable law.

10. Indemnification

You agree to indemnify and hold harmless Krono from any claims, damages, losses and expenses (including reasonable legal fees) arising from your products, your use of the Service, information you supplied that was inaccurate or incomplete, your violation of these Terms, or your infringement of any third-party rights.

11. Third-Party Services

The Service relies on third-party providers, including Paddle for course and book payments, payment providers for consulting invoices, email delivery providers and hosting providers. Their services are subject to their own terms and privacy policies, and we are not responsible for their availability or practices.

12. Availability and Changes

We aim for high availability but do not guarantee uninterrupted access to the Service. We may modify, suspend or discontinue any part of the Service, with reasonable notice where practicable.

We may update these Terms from time to time. The effective date at the top of this page shows when they last changed, and material changes are communicated by email to registered users. Continued use of the Service after that date constitutes acceptance of the updated Terms. An accepted consulting scope continues under the Terms in force when it was accepted, unless both parties agree otherwise.

13. Governing Law and Disputes

These Terms are governed by the laws of India. Any dispute arising from these Terms or your use of the Service is subject to the exclusive jurisdiction of the courts at Chennai, Tamil Nadu. Before starting any proceedings, both parties agree to try in good faith to resolve the dispute by discussion for at least 30 days. This does not affect any mandatory consumer protection rights you have where you live.
