Terms of Use

These Terms of Use (“Terms”) constitute a legally binding agreement between you (“User,” “you,” or “your”) and Kevin Erik Iin (“Beam,” “we,” “us,” or “our”) governing your access to and use of the Beam iOS application, the Beacon macOS application, and this website (collectively, the “Services”).

By downloading, installing, or using the Services, you agree to be bound by these Terms. If you do not agree to these Terms, do not download or use the Services.

If you download Beam through the Apple App Store, your use is also subject to Apple’s Media Services Terms and Conditions. In the event of any conflict between these Terms and Apple’s terms, Apple’s terms shall control with respect to Apple’s own services.

1. Description of the Services

Beam is a peer-to-peer screen-streaming application. The Beacon macOS application captures your Mac’s display and system audio and streams it, in encrypted form, to the Beam iOS application. By default both devices must be connected to the same local Wi-Fi network.

If you purchase Beam Unlimited, you may also stream when the two devices are not on the same local network, provided you have separately installed and signed in to Tailscale (a third-party VPN service) on both devices. In that mode the connection is carried over your own Tailscale network and may traverse the internet, including a Tailscale relay where a direct path cannot be established. Your Tailscale account and any relay involved are governed by Tailscale’s own terms and privacy policy, not ours.

In every mode, the stream travels between your own two devices and remains encrypted end to end. The Services operate no servers of our own in the streaming path, and we never receive, store, or process your screen content.

The Services are designed for personal viewing of your own Mac’s screen on your own iPhone, with limited controls such as click, keyboard input, and configurable shortcut, media, or macro buttons. They are not a full remote desktop solution and do not provide a desktop pointer, drag-and-drop, file transfer, or clipboard sync.

2. License Grant

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to:

• download and install the Beacon macOS application on Mac computers you own or control;
• download and install the Beam iOS application on iPhone devices you own or control; and
• use the Services for your personal, non-commercial use.

This license does not include any right to: (a) resell or commercially exploit the Services; (b) distribute copies of the Services to third parties; (c) publicly perform or display the Services; or (d) modify, translate, adapt, or create derivative works from the Services. All rights not expressly granted are reserved by us.

3. Free Tier and Session Limits

The Beam iOS application is available at no charge subject to the following usage limitations (the “Free Tier”):

• Free trial: Your first successful stream starts a three-day trial with no streaming limit.
• Free allowance: After the trial, you may stream for up to 30 minutes total in each 24-hour window. Time is accumulated across streams. Once the allowance is used, the stream will be automatically disconnected and the app displays the time until the window resets.
• Quality: Free Tier sessions are provided at full streaming quality. All app features are available during a Free Tier session.

The Beacon macOS application is provided free of charge with no usage restrictions.

We reserve the right to modify the Free Tier limitations at any time upon reasonable notice. Any changes will apply prospectively and will not affect any Beam Unlimited purchase you have already made.

4. In-App Purchase: Beam Unlimited

Within the Beam iOS application, you may purchase “Beam Unlimited” as a non-consumable in-app purchase (“IAP”) for a one-time fee of approximately $7.99 (price may vary by region and is set by Apple’s App Store pricing tiers). Beam Unlimited permanently removes the Free Tier streaming allowance and window restriction from the iOS application on your account.

4.1 Payment Processing

All payments are processed exclusively by Apple Inc. through the App Store. We do not collect, store, or process any payment information. Your purchase is subject to Apple’s Media Services Terms and Conditions and applicable App Store policies.

4.2 Restore Purchases

Beam Unlimited is tied to your Apple ID. If you reinstall the app or switch devices, you may restore your purchase at no additional charge by using the “Restore Purchases” function within the app (where available) or by reinstalling from the App Store. Beam Unlimited is a per-Apple-ID purchase; it is not transferable to a different Apple ID.

4.3 Refunds

All refund requests are handled exclusively by Apple. We do not process refunds directly. To request a refund, please contact Apple through reportaproblem.apple.com or through Apple Support. Refund eligibility is determined solely by Apple in accordance with their policies.

4.4 No Subscription

Beam Unlimited is a one-time purchase and does not constitute a subscription. No recurring charges will be made. Future major version upgrades may require a separate purchase, but you will always retain access to the version of the app you purchased for.

5. Acceptable Use

You agree that you will not use the Services to:

• violate any applicable law or regulation;
• infringe the intellectual property rights of any third party, including by streaming content you do not have the right to access or view;
• circumvent, reverse engineer, decompile, disassemble, or attempt to derive the source code of the Services;
• modify, adapt, translate, or create derivative works of the Services;
• sublicense, sell, resell, transfer, assign, or commercially exploit the Services;
• use the Services in any manner that could damage, disable, overburden, or impair the Services or networks connected to the Services;
• attempt to circumvent or exploit the Free Tier session or cooldown limitations through technical means, including but not limited to resetting device identifiers or manipulating system time; or
• use the Services for any unlawful or fraudulent purpose.

6. Intellectual Property

The Services, including all software, graphics, logos, icons, and documentation, are owned by Kevin Erik Iin and are protected by copyright, trademark, and other intellectual property laws. The Beam name and logo are proprietary marks of Kevin Erik Iin.

Nothing in these Terms transfers to you any ownership interest in the Services. You receive only the limited license described in Section 2.

The “Download on the App Store” badge and related marks are trademarks of Apple Inc., used under license.

7. Third-Party Content and Services

Beam streams the content displayed on your Mac’s screen. We are not responsible for, and have no control over, the content you choose to view using the Services. Your use of the Services to stream third-party content (such as video from streaming platforms, purchased media, or other applications) is governed by your agreements with the relevant content providers. You are responsible for ensuring that your use of the Services complies with all applicable terms of service and licensing agreements.

8. Disclaimer of Warranties

THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND TITLE. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS.

WE DO NOT WARRANT THAT THE SERVICES WILL MEET YOUR REQUIREMENTS OR THAT ANY ERRORS WILL BE CORRECTED. STREAMING QUALITY AND LATENCY DEPEND ON YOUR NETWORK CONDITIONS, WHICH ARE OUTSIDE OUR CONTROL. THIS APPLIES ESPECIALLY WHEN STREAMING FROM OUTSIDE YOUR LOCAL NETWORK, WHERE QUALITY ALSO DEPENDS ON YOUR INTERNET CONNECTION, YOUR MOBILE CARRIER, AND TAILSCALE, NONE OF WHICH WE CONTROL.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO THE ABOVE EXCLUSION MAY NOT APPLY TO YOU.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL KEVIN ERIK IIN BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES, INCLUDING BUT NOT LIMITED TO DAMAGES FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SERVICES, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL CUMULATIVE LIABILITY TO YOU ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES, WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER LEGAL THEORY, SHALL NOT EXCEED THE AMOUNT YOU PAID TO US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR $7.99, WHICHEVER IS GREATER.

NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, FRAUD, OR FRAUDULENT MISREPRESENTATION, OR ANY OTHER LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED BY APPLICABLE LAW.

10. Indemnification

You agree to defend, indemnify, and hold harmless Kevin Erik Iin and his successors and assigns from and against any claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable attorneys’ fees) arising out of or relating to: (a) your violation of these Terms; (b) your use of the Services in a manner not authorized by these Terms; or (c) your violation of any applicable law or the rights of any third party.

11. Termination

We reserve the right to suspend or terminate your license to use the Services at any time for any reason, including if we reasonably believe you have violated these Terms. You may stop using the Services at any time by uninstalling the applications. Sections 6, 8, 9, 10, 12, and 13 of these Terms survive any termination.

Termination of your license does not entitle you to a refund of any amounts paid. Refunds, if applicable, are governed by Apple’s refund policy.

12. Governing Law and Dispute Resolution

These Terms shall be governed by and construed in accordance with the laws of the Republic of Estonia, without regard to its conflict of laws principles. To the extent applicable, the laws of the European Union also apply, including the GDPR with respect to any personal data processing.

You and we agree to attempt to resolve any dispute arising out of or relating to these Terms or the Services through good-faith negotiation before initiating formal proceedings. Any dispute that cannot be resolved through negotiation shall be subject to the exclusive jurisdiction of the courts of the Republic of Estonia.

If you are a consumer resident in the EU, you may also use the European Commission’s Online Dispute Resolution (ODR) platform available at ec.europa.eu/consumers/odr.

Nothing in this section affects your statutory rights as a consumer under applicable law.

13. Apple-Specific Terms (EULA)
