Terms of Use

1. Acceptance of these terms

These Terms of Use (“Terms”) apply when you access heelen.app (the “Website”) or use the Heelen app for macOS (the “App”). By using the Website or App, you agree to these Terms. If you do not agree, do not use the Website or App.

“Heelen,” “we,” “us,” and “our” refer to the developer and publisher of Heelen. If you use Heelen for an organization, you confirm that you have authority to accept these Terms for that organization.

2. Mac App Store license

The App is licensed, not sold, through the Apple Mac App Store. Your license to use the App is governed by Apple’s Standard End User License Agreement (“Apple Standard EULA”), unless a different license is presented on the App Store product page.

These Terms govern the Website and add the product-specific terms below. If these Terms conflict with the Apple Standard EULA on a matter concerning your App license, the Apple Standard EULA controls.

3. What Heelen does and does not do

Heelen is designed for everyday visual privacy. While running, it can hide selected app windows and ask macOS to authenticate you before showing them again.

Heelen is not a security boundary or parental-control system. In particular, it:

• Does not encrypt, move, delete, or prevent direct access to an app’s files.
• Cannot prevent someone from force-quitting Heelen or using another macOS user account with access to the same information.
• Does not hide or suppress notifications generated by protected apps.
• Does not replace a strong Mac login password, FileVault, screen locking, backups, device management, or other system security controls.

You are responsible for choosing appropriate macOS security settings and deciding whether Heelen is suitable for your situation. The App may behave differently after macOS or third-party apps change, and no privacy-screen utility can guarantee that content will never become briefly visible.

4. Eligibility and responsible use

You may use Heelen only on Macs you own or are authorized to use, and only for lawful purposes. If local law requires a parent or guardian to approve your purchase or use, you must have that approval.

You must not misuse the Website or App, interfere with their operation, attempt to gain unauthorized access to related systems, distribute malware through them, or use them to violate another person’s rights. Restrictions on copying, modification, reverse engineering, redistribution, and transfer are also governed by the Apple Standard EULA and applicable law.

5. Purchases and refunds

Heelen is offered as a one-time purchase unless the Mac App Store product page states otherwise. Apple processes billing, taxes, receipts, refunds, and purchase support under its own terms and policies. Prices and availability may change before purchase. Heelen does not receive your full payment-card or Apple Account credentials.

6. Website and interactive demonstration

The Website provides general product information. Its interactive unlock demonstration is illustrative only: it does not authenticate you, protect any app, or send entered text to Heelen. Do not enter a real password into the demonstration.

The Website may use aggregate, cookie-free server-side analytics to understand general traffic and improve the Website, as described in the Privacy Policy.

We try to keep Website information accurate, but the current Mac App Store product page and in-App information control for price, compatibility, and available features at the time you download the App.

7. Intellectual property

The App, Website, product design, text, graphics, logos, and other Heelen materials are owned by Heelen or its licensors and are protected by intellectual-property laws. Except for the limited App license granted under the Apple Standard EULA, no right, title, or interest is transferred to you.

You may view and use the Website for personal, non-commercial purposes. You may not reproduce, republish, sell, or exploit Website materials without prior written permission, except where applicable law allows it. Apple, Mac, macOS, Mac App Store, Touch ID, and FileVault are trademarks of Apple Inc.; their use does not imply sponsorship or endorsement.

8. Third-party services and links

The Website and App may link to or depend on third-party services, including Apple services, website hosting and server-side analytics, and third-party applications you choose to protect. Those products are controlled by their respective providers and may have separate terms and privacy policies. Heelen is not responsible for third-party content, availability, security, or practices.

9. Availability, updates, and support

We may release updates, change features, correct errors, or discontinue all or part of the Website or App. We do not promise that either will always be available, uninterrupted, compatible with every application, or error-free. Any support we provide is subject to availability and does not create an additional warranty.

10. Warranties and liability

The warranties and remedies for the App are set out in the Apple Standard EULA and any rights that cannot be excluded under applicable law. To the fullest extent permitted by law, the Website and any related information are provided “as is” and “as available,” without additional express or implied warranties.

To the fullest extent permitted by law, Heelen is not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, business, privacy, or goodwill arising from the Website or App. Nothing in these Terms excludes liability or consumer rights that applicable law does not allow us to exclude or limit.

11. Suspension and termination

You may stop using the Website or App at any time. We may restrict access to the Website or end a license where the Apple Standard EULA or applicable law permits, including for a serious violation of these Terms. Provisions that by their nature should survive termination will continue to apply. These include intellectual property, disclaimers, limitations of liability, and dispute terms.

12. Applicable law and consumer rights

The Apple Standard EULA contains the governing-law provisions for your App license. These Terms do not take away any mandatory consumer protection, warranty, cancellation, or dispute-resolution rights you have under the law where you live. For the Website, applicable law and any mandatory local venue rules govern.

13. Changes to these terms

We may update these Terms to reflect changes to Heelen, the Website, or applicable requirements. We will publish the revised Terms here and change the effective date above. If a change is material, we will provide additional notice where appropriate. Your continued use after the updated Terms take effect means you accept them, to the extent permitted by law.
