What phos does with your data

The short version

The extension has no server of its own. It doesn't create an account for you, doesn't track you, and doesn't send your video, audio, or microphone anywhere except directly to YouTube's own ingest servers (if you choose to stream) or to your own computer's downloads (if you choose to record). This website separately collects only what you type into its feedback form or email signup, and nothing else.

The extension

What it captures

When you start a capture, phos records the tab, window, or screen you chose — and, only if you turn on "Include my microphone," your own microphone audio. All of this is encoded on your own computer. None of it is uploaded to a server operated by phos or Believers Tech Expo, at any point, under any circumstance — there isn't one in this path. See the source at github.com/btetotheworld/phos if you want to verify this yourself.

Where it goes

If you choose Recording, the finished file is downloaded straight to your computer through Chrome's own downloads system — phos never sees it after that point. If you choose Stream, encoded segments are uploaded directly from your browser to YouTube's HLS ingest servers (a.upload.youtube.com / b.upload.youtube.com), using the stream key you paste in from your own YouTube Studio account. That upload is between your browser and YouTube; phos is not in the middle of it and cannot see the contents.

Your YouTube stream key

Your stream key is a credential — treat it like a password. phos stores it only in Chrome's session storage for the extension, which clears automatically when you close the browser. It is never written to disk, never sent to any server besides YouTube's own ingest endpoint, and phos's own diagnostic logging never records it in full (only the last four characters, for troubleshooting).

Permissions, and why

• desktopCapture — to run Chrome's own picker so you can choose a tab, a window, or your screen to share.
• storage — to hold your stream key and preferences for the current browser session only.
• downloads — to save a recording to your computer when you choose Recording.
• Microphone access — requested only if and when you turn on "Include my microphone." You can revoke it at any time in Chrome's site settings for the extension.

What the extension does not do

No analytics, no third-party trackers, no advertising, no account creation, no OAuth, no data sale of any kind — there is nothing to sell, since nothing is collected.

This website

phos.believerstechexpo.com is a separate, ordinary website — it doesn't run any part of the extension and can't access your captures, microphone, or stream key. It collects data only in two places, both opt-in:

The feedback form

If you submit feedback, we receive whatever you typed — an optional name, an optional email address (only so we can reply), a category, and your message. It's emailed to the team via Resend, a transactional email service. We don't sell or share it, and we don't use it for anything besides reading and responding to it.

The email signup

If you submit your email to the waitlist, we store that address (also via Resend) to tell you when a new version ships and when there's an announcement. You can ask us to remove it at any time — see Contact, below.

What this website does not do

No analytics, no advertising cookies, no third-party trackers. It's hosted on Vercel, which processes standard server logs (IP address, request metadata) as any web host does — see Vercel's privacy policy for that layer.

Children's privacy

phos is not directed at children, and we don't knowingly collect information from anyone under 13.

Changes to this policy

If this changes, we'll update the date at the top of this page. Meaningful changes (anything that adds a new kind of data collection) will also be called out in the project's GitHub repository.
