Terms of Sale

Last updated: 7 September 2026

These terms govern the purchase and use of CadenceOne, a macOS application published by NativLab and distributed on the Mac App Store. Please read them before buying. Buying the application means you accept them.

1. Publisher

Publisher: Alex Lombry, Entrepreneur individuel (EI), trading as NativLab
Address: 173 rue de Courcelles, 75017 Paris, France
SIREN: 106 835 150
Registration: Registre National des Entreprises (RNE)
VAT: VAT not applicable (article 293 B of the French General Tax Code)
Contact: contact@nativlab.app

2. Who you are buying from

CadenceOne is distributed exclusively through the Mac App Store. The application is downloaded free of charge, and the full version is unlocked by a single in-app purchase. There is no other sales channel: we do not sell licence keys on this site or by email.

The purchase itself is concluded with Apple (Apple Distribution International Ltd., Hollyhill Industrial Estate, Hollyhill, Cork, Ireland), which distributes the application on our behalf. Apple collects the price, applies and remits any VAT or sales tax due in your country, and issues your receipt. The Apple Media Services Terms and Conditions therefore apply to the transaction, in addition to the present terms, as does Apple's standard Licensed Application End User Licence Agreement.

NativLab remains the publisher of the software and the party granting you the licence described in section 5, and remains your contact for support and for anything concerning the application itself.

3. Products and prices

Offer	Price	Term
Free trial	Free	14 days, all features
Lifetime unlock (in-app purchase)	59 €	One-time payment

The reference price is stated in euros. Apple converts it into your local currency according to its own pricing grid, and the final amount payable, including any tax applicable in your country, is displayed by the Mac App Store before you confirm your purchase. There is no subscription and no recurring charge.

We may change our price at any time. A change never affects a purchase already made.

4. Free trial

CadenceOne can be used free of charge for 14 days, with every feature unlocked. The trial requires no account, no email address and no payment method. It is tracked locally on your Mac. When it ends, the application keeps your data readable and exportable; the in-app purchase is required to continue using it fully.

5. Licence

5.1 What you get

We grant you a personal, non-exclusive, non-transferable right to install and use CadenceOne. The software is licensed, not sold; we retain ownership of it and of all intellectual property rights in it.

Lifetime unlock: the in-app purchase is attached to the Apple Account used to buy it, and can be used on every Mac signed in with that Apple Account, under the conditions set by Apple (including Family Sharing where Apple enables it). It does not expire. It includes free updates within the same major version (for example, all 1.x releases). A future major version may be a paid upgrade.
Teams: there is no separate team offer. An organisation equips its managers by buying one unlock per user, or through Apple Business Manager where applicable.

5.2 What you may not do

Resell, rent, sublicense, publish or otherwise distribute the software.
Circumvent the trial or the in-app purchase mechanism.
Modify, decompile or reverse engineer the software, except where and to the extent such acts are permitted by mandatory law, in particular the right to obtain interoperability information under article L122-6-1 of the French Intellectual Property Code.
Remove or alter any copyright or attribution notice.

Serious or repeated breach of this section may lead us to terminate the licence. Your data remains yours and stays on your Mac; termination affects your right to use the software, not your notes.

6. Ordering and delivery

An order is placed by confirming the in-app purchase with your Apple Account. The contract is formed when Apple accepts the payment.

Delivery is immediate: the application unlocks as soon as Apple confirms the purchase. There is no licence key, no account to create on our side and no server of ours to connect to. If you change or reinstall your Mac, use Restore purchases in the application while signed in with the same Apple Account. If a purchase does not unlock, write to contact@nativlab.app with your Apple receipt and we will help.

7. Trial, withdrawal and refunds

Try CadenceOne free for 14 days before you pay anything. The trial is complete and unrestricted: every feature, no account, no card. It exists so that you know exactly what you are buying before you buy it.

Because of that, we do not ourselves offer refunds for change of mind. Please use the trial. Refunds for App Store purchases are in any case granted and issued by Apple, under its own terms (see 7.2).

7.1 Statutory right of withdrawal

Consumers in the European Union normally have 14 days to withdraw from a distance contract. Because CadenceOne is digital content delivered immediately upon purchase, the right of withdrawal is lost once delivery has begun, in accordance with article L221-28 13° of the French Consumer Code. As the purchase is concluded with Apple, Apple's own terms govern the withdrawal and refund process for the transaction, and are more generous than the statutory minimum in practice.

7.2 How a refund works

The absence of a change-of-mind policy is not an absence of good faith. We support your refund request in the following cases:

Duplicate or accidental purchase: you were charged twice, or bought by mistake.
Non-delivery: the purchase was charged but the application never unlocked, and we are unable to make it work.
Non-conformity: the software does not do what this site says it does, and we cannot fix it within a reasonable time. This case is your statutory right, described in section 8, and nothing here limits it.

Refunds for App Store purchases are handled by Apple, not by us. We have no technical means of issuing a refund for a purchase made through the Mac App Store. Request one at reportaproblem.apple.com, or from your purchase history in the App Store, using the Apple Account used to buy. Apple decides on the request under its own terms and refunds the original payment method.

If your case falls into one of the situations above, write to contact@nativlab.app: we will confirm it in writing so that you can attach our answer to your request to Apple, and we will fix the underlying problem where one exists.

8. Legal guarantees

Whatever these terms say, consumers benefit from the legal guarantee of conformity for digital content and digital services (articles L224-25-12 and following of the French Consumer Code) and from the guarantee against hidden defects (articles 1641 and following of the French Civil Code). These guarantees are free of charge and are not limited by this contract.

If the software does not conform to what is described on this site, you may require it to be brought into conformity and, failing that, obtain a price reduction or a refund.

9. Support and updates

Support is provided by email at contact@nativlab.app, in English or French, on a best-effort basis and normally within a few working days. NativLab is a one-person company; there is no guaranteed response time.

Updates are published from time to time and are announced by email to licence holders. We do not guarantee that a given feature will exist forever, nor that the software will run on future versions of macOS beyond reasonable effort.

10. Liability

CadenceOne is a note-taking tool. It is your responsibility to keep backups of anything you cannot afford to lose; the application provides a full export to JSON for that purpose.

For professional buyers (any purchase made for business purposes), our total liability arising out of or in connection with the contract is limited to the amount you paid for the licence during the twelve months preceding the event, and we are not liable for indirect or consequential loss, loss of profit, loss of business or loss of data. Nothing in these terms limits liability for gross negligence, wilful misconduct, or personal injury, or any liability that cannot lawfully be limited.

11. Personal data

CadenceOne runs entirely on your Mac. Your notes, your team members' names and everything you write in the application stay in a local container on your machine. NativLab does not collect, receive, host or process that content, and has no technical means of accessing it.

Because the sale goes through the Mac App Store, we handle no personal data in connection with a purchase: payment, billing and identity data are processed by Apple, which provides us only with aggregated, anonymised sales reports. We learn neither your name nor your email address. The only case in which we hold personal data is when you write to us for support, and then only the content of your email, kept for as long as needed to answer you. You may exercise your rights of access, rectification, erasure, restriction, objection and portability at contact@nativlab.app, and lodge a complaint with the CNIL (cnil.fr).

12. Changes to these terms

We may amend these terms for future orders. The version applicable to your purchase is the one published on this page on the day of your order. Material changes are announced on this page with a new "last updated" date.

13. Governing law and disputes

These terms are governed by French law. This does not deprive a consumer of the protection afforded by the mandatory rules of the country in which they habitually reside.

In the event of a problem, please contact us first at contact@nativlab.app. Most things are settled in one email. Because purchases are concluded with Apple, complaints about the transaction itself (payment, receipt, refund) must be addressed to Apple under its own terms. Consumers resident in the European Union may in addition use the European online dispute resolution platform at ec.europa.eu/consumers/odr.

Failing an amicable settlement, the competent courts are those designated by the applicable rules of jurisdiction.
