Acceptance of Terms

These Terms of Use ("Terms") are a legal agreement between you and Keystone Apps ("we," "us," or "our") governing your use of the Screen Mirroring iOS application (the "App"). By downloading, installing or using the App, you agree to these Terms. If you don’t agree, please don’t use the App.

Description of the App

Screen Mirroring mirrors your iPhone or iPad screen to a TV and casts photos, videos, your camera, web pages and playlists to compatible devices on your Wi-Fi network. How each feature handles data is described in our Privacy Policy.

License to Use the App

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple-branded devices you own or control, solely for your personal, non-commercial use, in accordance with Apple’s App Store Terms of Service (the "Usage Rules" set out in Apple’s Media Services Terms and Conditions).

You may not, and may not permit anyone else to:

  • copy, modify, or create derivative works of the App;
  • reverse-engineer, decompile, or disassemble the App, except where applicable law permits it;
  • rent, lease, lend, sell, redistribute, or sublicense the App;
  • remove or obscure any proprietary notices in the App.

Subscriptions & Purchases

Screen Mirroring is free to download and use, with a Pro upgrade that unlocks the App’s full functionality. Pro is offered as an auto-renewing Weekly subscription, which may include a free trial for eligible new subscribers, or an auto-renewing Yearly subscription.

  • Price, duration and any trial are shown in the App and in the App Store listing before you purchase, and payment is charged to your Apple ID account at confirmation of purchase.
  • Subscriptions automatically renew for the same duration and at the then-current price unless auto-renew is turned off at least 24 hours before the end of the current period.
  • Your account will be charged for renewal within 24 hours prior to the end of the current period.
  • If a free trial is offered, any unused portion is forfeited once you purchase a subscription, where applicable.
  • You can manage or cancel your subscription, and turn off auto-renewal, at any time in your device’s Settings → [your name] → Subscriptions — cancelling doesn’t affect the current paid period, which remains active until it ends.
  • All purchases are processed by Apple through your App Store account; refunds are handled by Apple under its own policies, not by us directly.

The free tier gives you a limited trial of each casting feature, and free screen mirroring is additionally limited in length and quality. Two things worth stating plainly: that free allowance is counted per device and does not reset if you delete and reinstall the App, and free-tier limits may change between versions, so they are not a guarantee of a fixed allowance.

Acceptable Use

You agree not to:

  • use the App in any way that violates applicable law;
  • mirror, cast or record content you do not have the right to display or distribute, or use the App to circumvent any copy protection;
  • connect to or control a device you don’t own and aren’t authorised to use;
  • use the App to display content in a public or commercial setting without the necessary rights;
  • attempt to circumvent free-tier limits or Pro entitlement checks, or interfere with the App’s operation.

Third-Party Content

The App does not host, curate or provide any video, channel or playlist of its own. Anything you open, search for, add by URL or cast through the App comes from a third party — a website, a video service, or a playlist address you supply — and is governed by that provider’s own terms. You are solely responsible for making sure you have the right to access and display any content you use the App with, and we disclaim responsibility for the availability, legality or accuracy of third-party content.

Your Content

You retain all rights to the photos, videos, playlists and other content you cast or add through the App ("Your Content"). We don’t claim ownership of Your Content. As described in our Privacy Policy, it travels directly between your device and your TV over your own network and is never uploaded to us.

Third-Party Services

The App uses Google’s Cast SDK to discover and cast to Chromecast and Google TV devices, and Apple’s system frameworks for screen capture and streaming. Subscription purchases are processed by Apple through the App Store. See our Privacy Policy for details. These third-party services operate under their own terms and privacy policies, which we don’t control, and we are not responsible for their availability.

Intellectual Property

The App, including its design, graphics, text, and underlying code, is owned by Keystone Apps or its licensors and is protected by copyright, trademark, and other intellectual property laws. These Terms don’t grant you any rights to our trademarks or branding, and don’t grant us any rights to Your Content beyond what’s needed to provide the App’s features to you.

Disclaimers

The App is provided "as is" and "as available," without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We don’t guarantee that the App will discover, connect to or successfully mirror to every TV, model or firmware version, or that streaming will be uninterrupted, lag-free or error-free — performance depends on your network, your devices and third-party hardware and software we don’t control. Some apps and services also block mirroring of their content, which is outside our control.

Limitation of Liability

To the maximum extent permitted by law, Keystone Apps will not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the App — including a failed or interrupted session, an incompatible device, or content unintentionally displayed while mirroring. Our total liability for any claim arising from these Terms or the App is limited to the amount you paid us in the 12 months before the claim arose.

Nothing in these Terms limits any liability that can’t be limited under applicable law.

Termination

You may stop using the App at any time by deleting it from your device (and cancelling any active subscription separately through your Apple ID settings, since deleting the App does not cancel a subscription). We may suspend or terminate your access if you violate these Terms. Provisions that by their nature should survive termination (such as Your Content, Intellectual Property, Disclaimers, and Limitation of Liability) will survive.

Changes to These Terms

We may update these Terms from time to time. We’ll update the "Last updated" date above, and material changes will be communicated where appropriate (such as an in-app notice). Continuing to use the App after changes take effect means you accept the updated Terms.

Governing Law

These Terms are governed by generally applicable law, without regard to conflict-of-law principles, except where mandatory consumer-protection laws of your country of residence require otherwise. Apple is not a party to these Terms and has no obligation to provide support or maintenance for the App.
