Terms & Conditions

Publisher identification

Scope and acceptance

These terms apply to every visitor to chronobiohacker.com and to every purchase of a digital product sold through the site. They form the entire agreement between you and us in respect of that purchase.

By placing an order you confirm that you have read and accepted these terms. Acceptance is recorded by an explicit checkbox at checkout; an order cannot be completed without it. You must be at least 18 years old and have legal capacity to contract.

We may update these terms. The version applicable to your purchase is the one in force on the date of your order, and we keep an archive of previous versions available on request.

Products

We sell digital content supplied without a tangible medium: written guides and protocols in PDF or ebook format, audiobook versions of those guides, bundles combining several of the above, and any accompanying digital resources such as tracking templates.

Product pages describe the essential characteristics of each product: format, approximate length, what it contains, and the technical requirements to use it. Screenshots and extracts are illustrative. We reserve the right to withdraw or modify any product at any time; a withdrawal never affects an order already placed.

All products are educational. They are not medical advice and are not a substitute for professional care — see our Medical Disclaimer, which forms part of these terms.

Orders

The ordering process is: you select a product, you review your basket and the total price, you provide the information required to complete the order, you tick the box accepting these terms and acknowledging the point set out in section 08, and you confirm payment. Confirming payment creates a binding obligation to pay.

We send an order confirmation by email. That confirmation, together with these terms, constitutes the record of the contract. If you spot an error in your order, contact us immediately — before download begins we can usually correct it.

We may refuse or cancel an order in case of a manifest pricing error, suspected fraud, a payment dispute on a previous order, or where fulfillment would breach applicable law. If we cancel, any sum already taken is refunded in full.

Prices and taxes

Prices are shown on the product page in the currency indicated there, and are payable in full at the time of order. The price applicable is the one displayed at the moment you confirm payment.

• We operate under the French micro-entreprise VAT exemption. No French VAT is charged, and invoices carry the statutory mention TVA non applicable, art. 293 B du CGI.
• Prices are displayed and charged in US dollars unless the product page states otherwise.
• Depending on your country or state of residence, you may nonetheless be liable for local taxes on digital products or services — several US states tax digital goods. Where such a tax applies and is not collected at checkout, it is your responsibility.
• Your bank or payment provider may apply currency conversion charges. These are outside our control.

We may change prices at any time. A change never applies retroactively to an order already placed.

Payment

Payments are processed by Stripe and PayPal. We do not collect, process or store your card details at any point; they are handled directly by the payment provider under its own terms and privacy policy.

Your order is confirmed once the provider authorizes the payment. If authorization fails, the order is not concluded and no access is granted. In the event of a chargeback or unpaid amount, we may suspend access to the product concerned until the situation is resolved.

Delivery and access

Digital products are delivered immediately after payment is confirmed, by a download link sent to the email address supplied with the order and displayed on the confirmation page. Delivery is deemed complete when that link is made available to you.

It is your responsibility to give a valid email address and to check your spam folder. If the link has not arrived within one hour, contact us and we will resend it.

Access is granted for your personal use for the lifetime of the product. We may issue updated versions of a product; where we do, existing buyers receive the update at no charge. We do not guarantee indefinite availability of download links, and we recommend you save your files locally on receipt.

Right of withdrawal and its waiver

Under French and EU consumer law you normally have fourteen days to withdraw from a distance contract without giving a reason. For digital content supplied without a tangible medium, that right is lost once performance has begun, provided you have expressly consented to it and acknowledged the consequence — article L221-28 13° of the French Consumer Code.

Once you have given that consent and the download has begun, the purchase is final and no refund is due. If you would prefer to keep your withdrawal right, do not tick the box — but access cannot then be granted before the fourteen-day period has elapsed.

This waiver concerns the right of withdrawal only. It does not affect, and cannot affect, the statutory rights described in the next section.

If you are buying from outside the European Union

The fourteen-day right of withdrawal described above is a right granted by European Union law. It does not exist as a general statutory right in the United States or in most other jurisdictions. If you are buying from outside the EU, the position is simply this: digital products are delivered immediately and all sales are final, except in the circumstances set out in section 09. This policy is stated on every product page and at checkout before you pay, and you are asked to confirm it as a separate step. Nothing in this section limits any non-waivable right you may have under the law of your own state or country.

Legal guarantee of conformity

Regardless of the waiver above, you retain the legal guarantee of conformity for digital content set out in articles L224-25-12 and following of the French Consumer Code, and the guarantee against hidden defects under articles 1641 and following of the Civil Code. These rights are mandatory and cannot be excluded by contract.

In practice, if a product is faulty, corrupted, incomplete, materially different from its description, or technically inaccessible through no fault of your own, contact us at hello@chronobiohacker.com. We will bring the product into conformity — normally by supplying a working file or a corrected version — and, where that is impossible or disproportionate, we will refund you.

We also refund in full, without discussion, in the case of a duplicate charge or a payment taken in error.

Disagreeing with the content of a guide, or finding it less useful than you hoped, is not a conformity defect. Product pages describe what each product contains precisely so that you can judge before buying.

Before opening a dispute with your bank or card issuer, please write to us. Nearly every problem — a link that did not arrive, a file that will not open, a duplicate charge — is resolved within a day. A chargeback filed without contacting us first costs both sides time and money, and we may suspend access to the product concerned while the dispute is open.

License and intellectual property

All content on this site and in our products — text, structure, illustrations, charts, protocols, the ChronoBiohacker name and its visual identity — is protected by intellectual property law and remains our property or that of our licensors.

Purchasing a product grants you a personal, non-exclusive, non-transferable license to use it for your own private purposes. You may print a copy for your own use and store it on your own devices.

• You may not resell, rent, sublicense, share or redistribute a product, in whole or in part, by any means
• You may not publish a product, or any substantial extract from it, on a website, file-sharing service, messaging group or social platform
• You may not remove or alter any authorship, copyright or license notice
• You may not use our content to train a machine learning model or to generate derivative commercial content
• You may quote short extracts with clear attribution and a link, as normal citation practice allows

Serious or repeated breach entitles us to terminate your license and revoke access, without prejudice to any other remedy.

Use of the site and of free resources

Free content, including articles, pillar guides, downloadable lead magnets and email newsletters, is provided for your personal information under the same license terms as paid products.

Every commercial email we send identifies us, carries our postal address, and includes a working unsubscribe link. Unsubscribing takes effect promptly and you will not be asked to give a reason or to log in to do it. If an unsubscribe link fails, write to us and we will remove you manually.

You agree not to attempt to disrupt the site, to access areas you are not authorized to access, to extract content by automated means at scale, or to use the site in a way that breaches applicable law.

Liability

Our content is educational and general in nature. You remain responsible for how you use it and for any decision you take on the basis of it. The Medical Disclaimer sets out the health-specific limits in detail and forms part of these terms.

To the fullest extent permitted by law, we are not liable for indirect or consequential loss, for loss of profit or opportunity, or for any outcome arising from your use of, or reliance on, our content. Where our liability is established, it is limited to the amount you paid for the product concerned.

Nothing here excludes or limits liability that cannot lawfully be excluded, in particular liability for death or personal injury caused by negligence, for fraud, or under the mandatory guarantees described in section 09.

We aim to keep the site available but do not guarantee uninterrupted access. Maintenance, technical incidents and third-party outages happen.

Force majeure

Neither party is liable for failure to perform where that failure results from an event beyond its reasonable control, including network or hosting failures, cyber-attack, the failure of a payment provider, natural disaster or an act of a public authority.

Personal data

We process personal data in accordance with the GDPR and French data protection law. What we collect, why, how long we keep it, who processes it on our behalf and how to exercise your rights are all set out in our Privacy Policy.

Residents of California and of other US states with comprehensive privacy laws have additional rights, including the right to know what personal information we hold, to request its deletion, and to opt out of any sale or sharing of it. We do not sell personal information. The Privacy Policy explains how to exercise these rights and how we respond to a Global Privacy Control signal.

Complaints and consumer mediation

If something has gone wrong, write to hello@chronobiohacker.com first. We answer every complaint and most things are resolved directly.

If we cannot resolve it, you may refer the matter free of charge to a consumer mediator, as provided by articles L611-1 and following of the French Consumer Code.

Governing law and jurisdiction

These terms are governed by French law. If you are a consumer resident in another country, this choice does not deprive you of the protection of the mandatory consumer rules of your country of residence.

In the event of a dispute, the parties will seek an amicable solution before any legal action. Failing that, the competent courts are determined by the applicable rules of civil procedure; as a consumer you may bring proceedings before the courts of your place of residence.

If you are resident in the United States, you keep the benefit of the mandatory consumer protection rules of your state, and nothing in these terms requires you to waive them. We have deliberately not included a mandatory arbitration clause or a class action waiver: such clauses are common in US terms but are treated as unfair and unenforceable against consumers in the European Union, and we would rather have one set of terms that is valid on both sides of the Atlantic than two that conflict.
