NotchFi — End User License Agreement (EULA)

Version 1.0 · Effective October 10, 2026

Please read this agreement carefully. By downloading, installing or using NotchFi (the "App"), you agree to be bound by it. If you do not agree, do not install or use the App.

This agreement is between you and Yusuf Arda Kaya (the "Developer", "we", "us"). It is not an agreement with Apple Inc. ("Apple").

1. Acknowledgement

You and the Developer acknowledge that this agreement is concluded between you and the Developer only, and not with Apple, and that the Developer, not Apple, is solely responsible for the App and its content. Your use of the App must comply with the Usage Rules set out in the Apple Media Services Terms and Conditions; if any provision of this agreement conflicts with those Usage Rules, the Usage Rules prevail.

2. License

The Developer grants you a limited, non-exclusive, non-transferable, revocable license to install and use the App on any Apple-branded devices that you own or control, as permitted by the Usage Rules. The App may also be used by other accounts associated with you through Family Sharing or volume purchasing, as the Usage Rules allow. The App is licensed to you, not sold.

3. Restrictions

Except to the extent that applicable law does not allow these restrictions, you may not:

• copy, modify, translate or create derivative works of the App;
• reverse engineer, decompile, disassemble or try to derive the source code of the App;
• rent, lease, lend, sell, sublicense, redistribute or otherwise transfer the App or your rights to it;
• remove or alter any copyright, trademark or other proprietary notices;
• use the App, or the network services it contacts, for unlawful purposes or in a way that disrupts or overloads them, for example by automating or abusing speed tests or circumventing rate limits.

4. Ownership and intellectual property

The App, including its name, logo, icon, design, text and code, is owned by the Developer and is protected by copyright and other intellectual property laws. No rights are granted to you except those expressly stated in this agreement. Apple, Mac, macOS, iPhone, Wi-Fi, Cloudflare and other names mentioned in the App belong to their respective owners; the App is not affiliated with or endorsed by them. If you send feedback or suggestions, the Developer may use them without obligation to you.

5. Price, updates and future features

The App is currently free. The Developer may release updates, change or remove features, and may in the future offer optional paid features through in-app purchase on the App Store, under the terms shown at the time of purchase and Apple's terms.

6. Privacy

The App has no accounts and does not collect personal data, use analytics, show advertising or track you. Your settings and usage statistics (daily data counts per network and the latest speed test result) are stored only on your Mac. The App connects to the internet only for these features:
These services may see your IP address, as with any internet request, and handle it under their own policies.
The App may ask for these optional permissions: Location (macOS shares the Wi-Fi network name only with apps that have Location access; the App never reads or stores your location), Notifications (data plan warnings) and Launch at Login (off by default).
Full details are in the Privacy Policy: https://yusufkaia.tech/notchfi-site/privacy.html

• Speed test: data is downloaded from and uploaded to speed.cloudflare.com when you start a test.
• Carrier name: a small request to speed.cloudflare.com identifies the network operator (ASN), and stat.ripe.net returns that operator's public name. You can turn this off in Settings > Privacy.

7. Third-party services, data charges and third-party terms

Speed tests transfer data and may count against your data plan or incur charges from your carrier or internet provider; you are responsible for those charges. The App offers a lighter test on metered connections, but you decide when to run a test. When using the App you must comply with any applicable third-party terms of agreement, for example your wireless data service agreement or the terms of your carrier's hotspot or tethering service. Third-party services the App depends on may change or become unavailable, and the related features may then stop working.

8. Measurements are estimates

Signal strength, noise, link rate, speeds and data usage shown by the App are measured or estimated from information provided by macOS and by test servers. Results vary with time, network, server and device, and may differ from other tools or from your carrier's or provider's billing counters. Do not rely on the App for billing disputes or for safety-critical, medical, legal or other professional decisions. When your Mac uses an iPhone's Personal Hotspot, the App shows the strength of the Wi-Fi link between your Mac and the iPhone, not the iPhone's cellular signal.

9. Third-party software

The App does not include third-party software libraries. It uses system frameworks provided by Apple under Apple's license terms.

10. Maintenance and support

The Developer is solely responsible for providing any maintenance and support services for the App. Support is provided on a best-effort basis through the support page (https://yusufkaia.tech/notchfi-site/support.html). Apple has no obligation whatsoever to furnish any maintenance and support services for the App.

11. Warranty

To the maximum extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind. The Developer is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any, for the App to you; to the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be the Developer's sole responsibility. Your mandatory rights as a consumer are not affected.

12. Limitation of liability

To the maximum extent permitted by law, the Developer is not liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, profits or goodwill, arising from your use of or inability to use the App. The Developer's total liability for direct damages is limited to the amount you paid for the App, if any. Nothing in this agreement excludes or limits liability that cannot be excluded or limited by law, including liability for intent, gross negligence, death or personal injury, or your mandatory consumer rights.

13. Product claims

The Developer, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession or use of it, including: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation.

14. Intellectual property claims

If a third party claims that the App, or your possession and use of it, infringes that third party's intellectual property rights, the Developer, not Apple, is solely responsible for the investigation, defense, settlement and discharge of that claim.

15. Legal compliance

You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country, and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties. You agree to comply with all laws that apply to your use of the App, including export control and sanctions laws.

16. Term and termination

This agreement is effective until terminated. You may terminate it at any time by deleting the App. Your rights under this agreement end automatically, without notice, if you breach it; you must then stop using the App and delete all copies. Sections that by their nature should continue to apply after termination will do so.

17. Changes to this agreement

The Developer may update this agreement, for example with a new version of the App. The current version is available on the App Store listing and at https://yusufkaia.tech/notchfi-site/eula.html. Continuing to use the App after an update means you accept the updated agreement, to the extent permitted by law.

18. Governing law

This agreement is governed by the laws of the Republic of Türkiye, without regard to its conflict-of-laws rules, subject to Apple's rights as third-party beneficiary and to the mandatory consumer protection rules of your country of residence. Consumers in Türkiye may apply to the competent consumer arbitration committees and consumer courts under Law No. 6502; other disputes are subject to the competent courts of Türkiye unless mandatory law provides otherwise.

19. General

This agreement, together with the Privacy Policy and the Apple terms referred to above, is the entire agreement between you and the Developer about the App. If a provision is found unenforceable, the rest remains in effect. A failure to enforce a provision is not a waiver. You may not assign this agreement without the Developer's written consent; the Developer may assign it. This agreement is provided in English and Turkish; if they differ, the English version prevails, except for users in Türkiye, for whom the Turkish version prevails.
