Terms of Use

These Terms of Use (the Terms) govern your access to the website at getnotchnook.com, the NotchNook application, and related materials (together, the Services). The Services are operated by CETUX LAB TECNOLOGIA LTDA., CNPJ 64.376.133/0001-40, Brazil (Cetux Lab, we, us, or our).

NotchNook is published under the lo.cafe brand by lo.cafe Ltda., a company of the Cetux Lab group. Cetux Lab is the parent company and answers for the Services under these Terms.

By downloading, installing, accessing, or using the Services, you agree to these Terms. If you do not agree, do not use the Services.

1. What we offer

The Services make the NotchNook installer and technical information available and sell licences for the application: a monthly subscription and a one-time lifetime licence. Prices are shown in US dollars; at checkout, customers in Brazil may be offered payment in Brazilian reais. Payments are handled by a third-party payment processor, and the processor's own terms apply to the payment itself. The announced promotional period is the deadline to join an offer. For monthly subscriptions purchased with the relaunch price-lock offer, the monthly price shown at checkout continues for as long as that subscription remains active, including after the offer ends. Once the subscription ends, a new subscription is subject to the prices and offers available at that time.

2. Eligibility and permitted use

You may use the Services only in compliance with applicable law and these Terms. You are responsible for the devices, operating system, internet connection, and backups necessary to use the application.

3. Software license

Subject to these Terms and any applicable license terms delivered with the software, Cetux Lab grants you a limited, non-exclusive, non-transferable, revocable license to download, install, and use NotchNook on Mac devices that you own or control, solely for personal or internal business use.

You may not, except where applicable law prohibits a restriction:

• copy, modify, translate, or create derivative works of the software;
• reverse engineer, decompile, disassemble, or attempt to derive its source code;
• rent, lease, sell, sublicense, distribute, or make the software available to others;
• remove proprietary notices or circumvent security, activation, or technical restrictions; or
• use the Services to interfere with, damage, or gain unauthorized access to systems or data.

4. Purchases, licences, trial and refunds

NotchNook includes a 48-hour trial inside the application, which restarts on each feature update so you can try what changed.

A licence purchased through the new checkout from 24 September 2026 onward activates on up to two Macs. Purchases and subscriptions from the previous store do not migrate or activate automatically in the current application. A previous lifetime buyer may request an individual support review or purchase a new licence, without a promise of approval or response time for the review. A previous subscriber may start a new subscription through the current checkout.

If a previous subscription still creates charges, use the Manage subscription link in an old Stripe receipt or subscription email to cancel it. The old and new billing systems are separate, and a new purchase does not cancel an old charge.

The application validates the licence with our server. A licence stays valid offline for up to 30 days between checks.

You may request a refund within 7 days of a purchase through the new checkout by writing to support@getnotchnook.com. A refund ends the licence: access stops the next time the application validates it, which can take up to 30 days on a Mac that stays offline. Partial refunds outside that window are reviewed case by case.

A monthly subscription purchased through the new checkout renews until you cancel it. You can cancel it through the billing portal linked from the application's licence settings; cancelling stops future renewals and does not refund the current period.

Nothing in this section limits the statutory rights of consumers, including the right of withdrawal under Brazilian consumer law.

5. Installation and Apple notarisation

NotchNook is distributed outside the Mac App Store, signed with a Developer ID certificate and notarised by Apple. The first time you open it, macOS verifies the download and asks you to confirm that you want to open it; the download page explains the steps. The only official download is the one published on getnotchnook.com. Copies obtained elsewhere are not ours, are not checked by us, and are not covered by these Terms.

6. Updates and changes

We may update, modify, suspend, or discontinue any part of the Services. An update may be required for continued compatibility, security, or operation. We do not promise that a particular feature, version, integration, or service will remain available.

7. Intellectual property

The Services, including their software, design, content, logos, names, and other materials, are protected by applicable intellectual-property laws. Except for the limited license above, these Terms do not give you any ownership interest or other right in the Services or our intellectual property.

NotchNook and related names, marks, and visual elements may not be used without prior written permission, except for fair and lawful references to the product.

8. Feedback

If you send us suggestions, ideas, or feedback, you grant us a worldwide, perpetual, irrevocable, royalty-free right to use, reproduce, modify, and incorporate that feedback without compensation or obligation to you.

9. Third-party services

The Services may link to or interoperate with third-party software, websites, or services, including the payment processor used at checkout. Those third parties are responsible for their own offerings and terms. We are not responsible for third-party content, availability, or practices.

10. Disclaimers

THE SERVICES ARE PROVIDED AS IS AND AS AVAILABLE. TO THE MAXIMUM EXTENT PERMITTED BY LAW, CETUX LAB DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. We do not warrant that the Services will be uninterrupted, error-free, secure, compatible with every device or macOS version, or free from harmful components.

Nothing in these Terms excludes a warranty or right that cannot lawfully be excluded.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, CETUX LAB WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO THE SERVICES.

Where liability cannot lawfully be excluded, Cetux Lab's aggregate liability for all claims arising from the Services is limited to the amount you actually paid to Cetux Lab for the Services during the twelve months before the event giving rise to the claim. If you paid nothing, Cetux Lab has no liability, to the maximum extent permitted by law. This limitation does not apply where applicable law prohibits it, including mandatory consumer-protection rules.

12. Indemnity

To the maximum extent permitted by law, you will indemnify and hold Cetux Lab harmless from claims, losses, liabilities, and expenses arising from your unlawful use of the Services or breach of these Terms.

13. Termination

These Terms remain in effect while you use the Services. We may suspend or terminate your access if we reasonably believe you have violated these Terms, created risk for the Services or others, or are required to do so by law. On termination, the license granted in Section 3 ends.

14. Governing law and disputes

These Terms are governed by the laws of Brazil, without regard to conflict-of-law rules. Any dispute will be submitted to the courts with jurisdiction at Cetux Lab's legal domicile, except where mandatory consumer-protection law provides otherwise.

15. Changes to these Terms

We may revise these Terms from time to time. The revised Terms will be posted on this page with a new effective date. Your continued use after they take effect constitutes acceptance to the extent permitted by law.
