Privacy
Last updated: October 25, 2026
CastPresenter is made by Chicago Business Innovations LLC (“we”, “us”). This policy explains what the CastPresenter Mac app, its browser extension and this website collect, why, who helps us handle it, and the choices you have. Using CastPresenter is also covered by our Terms of Service.
The app
CastPresenter runs entirely on your Mac. Your phone or camera picture goes only to your own computer — your browser or a floating window on the same machine — and never leaves it.
While your phone is mirrored, its sound plays through your Mac unless you turn on Mute phone audio. CastPresenter never records or sends audio or video.
The app has no account system and shares nothing unless you choose to. If you turn on “Share anonymous usage data” — when you first open CastPresenter, or later in its Settings — it sends us anonymous usage events (such as starting a stream or opening the viewer), app logs with device names removed, and crash reports, tied to a random ID created on your Mac. You can turn it off at any time. It never sends your screen, your sound, or your phone’s name.
When you send a report with “Report issue” in the app’s menu, we receive your summary and description as you wrote them, your email address if you add it (we use it only to reply to you about that report), a random Support ID, a random ID that keeps reports sent with the same Support ID together and, if you leave “Include diagnostics” ticked, the app and macOS versions, sharing status, whether you have Pro and recent app logs, with device names removed. Nothing is sent until you click “Send report”, and sending a report doesn’t turn on usage data. If usage data is on when you send, the Support ID is the same random ID your usage data uses, so we can see your recent usage events next to your report. If it’s off, the report carries its own random IDs, not the ones your usage data uses; but if you give the same email address on a report you send while usage data is on, the two can be connected by that address. Reports, including your email address and the start of your message, are stored in PostHog, our support and analytics provider, in the United States, both as support tickets and in its event records.
Purchases are handled by Apple through the App Store; we never see your payment details.
The browser extension
The CastPresenter browser extension shows the picture from the CastPresenter app on your own computer (at 127.0.0.1); that picture never leaves your computer.
If you agree when the side panel first asks, the extension sends us usage statistics so we can learn how it’s used: when it’s installed, updated or removed, which of its controls you use, whether it can reach the CastPresenter app, how long the side panel is open and showing a picture, whether the app’s free-session limit was reached and whether you clicked Upgrade, the extension and browser versions, your operating system, and a random ID stored in your browser. It never sends the picture, the pages you visit, or anything you type. The statistics go to PostHog, our analytics provider, which stores them in the United States. Nothing is sent until you choose. You can change your answer at any time in the side panel under ⚙ › Share anonymous usage stats, and email support@castpresenter.com to have past statistics deleted.
The extension’s use of this information complies with the Chrome Web Store User Data Policy, including its Limited Use requirements: it is used only to understand and improve CastPresenter, never sold, and never used for advertising.
After you install or remove the extension, it may open a page on this site. If you’ve agreed to the extension’s usage statistics and allow analytics here, visits from the extension are linked to its random ID, so we can tell which visits lead to installs.
This website
When you ask us to send you the download links, or to tell you when CastPresenter for Windows is ready, we store the email address you give us with a little context: the page and form you used, any campaign tags in the link, and the country your connection comes from. We use it to send that email and to see which pages bring people in. It’s kept in PostHog, which also sends our emails and stores this in the United States. Our emails don’t track whether you open them or which links you click.
If you tick “Keep me updated”, we’ll also send occasional news about CastPresenter. Those emails, like the Windows launch email, include an unsubscribe link, and you can reply to any of our emails to stop. You can ask us to delete your address at any time at support@castpresenter.com.
To see how visitors use the site and which pages lead to downloads, we use PostHog, a product analytics service. It records the pages you view, what you click, how you arrived (such as the referring site and campaign tags), your browser and device type, your approximate location worked out from your IP address (the address itself isn’t kept), and recordings of how pages are used, with anything you type into a form hidden. In Europe we ask before PostHog uses cookies; elsewhere it uses a cookie and your browser’s local storage to recognise return visits, and it respects your browser’s Global Privacy Control signal. If you say no, visits are only counted, without cookies. PostHog stores this data in the United States.
Analytics on this site is .
The site remembers your light or dark choice in your browser; that stays on your device. We don’t sell your data or share it with anyone else.
Who we share it with
Only the service providers that run CastPresenter for us, under their own data-protection terms: PostHog (usage statistics, website analytics, our support inbox and the emails we send), Cloudflare (hosts this website and passes email sent to our addresses to PostHog), and Apple, which handles App Store purchases. Google and Microsoft distribute the browser extension under their own policies. We don’t sell personal information or share it for advertising, and we don’t use it to build advertising profiles. We may disclose information if the law requires it.
How long we keep it
Usage statistics, diagnostics and support messages are kept only as long as we need them to improve CastPresenter and to help you, and are deleted when you ask. Email addresses stay on our lists until you unsubscribe or ask us to delete them. Data is stored in the United States.
Your choices and rights
You can turn sharing off at any time: in the app’s Settings, in the extension under ⚙, and with the switch above for this website. You can ask us what we hold about you, or to correct or delete it, by writing to support@castpresenter.com; include your Support ID from the app if you have one, so we can find your data. We answer within 30 days.
Depending on where you live, you may have further rights, for example under the GDPR in the EU and UK (to object to or restrict processing, to data portability, and to complain to your data protection authority) or under California law (to know, delete and correct, and not to be discriminated against for using these rights). We rely on your consent for the app’s and extension’s usage data and for analytics cookies in Europe, on your request for the emails and support replies you ask for, and on our legitimate interest in counting visits without cookies and keeping our services secure.
Children
CastPresenter isn’t directed to children under 13, and we don’t knowingly collect their personal information. If you think a child has sent us information, write to us and we’ll delete it.
Changes to this policy
If we change this policy we’ll update the date at the top, and for significant changes we’ll say so on this site or in the app before they take effect.
