Is PostSnag a bot? Does it automate Facebook?

No. PostSnag is not a bot, and it does not automate anything on Facebook. It doesn't log in on its own, doesn't post or act on your behalf, and nothing runs in the background. It only reads the public posts you scroll past yourself, and it only syncs to your dashboard when you click Export To Dashboard.

Here's exactly what that means, mechanically, so you're not just taking it on faith.

What actually makes something a "bot"

A bot, in the sense people usually mean it, logs in independently, takes actions without a person driving them (posting, liking, commenting, following, messaging), and often runs continuously, whether or not anyone's watching, frequently paired with fake accounts or proxies to avoid detection. PostSnag has none of these traits. There's no PostSnag process signing into Facebook for you, no scheduled task posting or interacting on your behalf, and no hidden loop running while you're away from the tab.

What happens while you scroll

You open a Facebook profile, Page, or group in your own signed-in session, and you scroll it yourself. PostSnag reads two things as that happens: the posts rendered on the page in front of you, and the same data Facebook's own page already loaded to build what you're looking at. It doesn't send extra requests beyond your normal browsing, and it doesn't need to; everything it captures already arrived in your browser because you opened the page and scrolled it. As posts load, PostSnag reads their type, caption, engagement, date, and media, and keeps a running count in the panel. Your scrolling is what drives what gets captured, not the other way around.

What happens the moment you stop scrolling

Nothing. PostSnag doesn't keep capturing after you stop scrolling, doesn't run when the Facebook tab is closed, and doesn't check Facebook on a schedule. Capture pauses the instant you stop; there's no timer, no background loop, and no polling for new posts while you're away from the tab. Switching to a different tab or app doesn't keep it running either, since capture is tied to the Facebook tab actually being open and actively scrolled. Captured posts sit locally in your browser until you decide to send them up.

Syncing only happens when you click Export To Dashboard

Scrolling saves posts to your browser only. Nothing reaches your PostSnag dashboard, or leaves your device at all, until you click Export To Dashboard in the panel. That's a manual action you take when you're ready, not an automatic background sync. If you close the tab mid-scroll without exporting, whatever you already captured stays saved locally and is still there the next time you open that profile.

The one narrow exception: capturing from a Facebook Group

There's one specific, limited case worth being upfront about. When you export posts captured from inside a Facebook Group, PostSnag makes a single same-origin request to that group's own public page, in your own session, to read its name and cover image for your dashboard. That's the same page your browser would load if you visited the group directly. It's used only for that one purpose and is never applied to your regular Facebook browsing elsewhere.

Why "is this a bot" comes up, and why it doesn't apply here

The worry makes sense in general: plenty of Facebook tools really do run on proxy networks, fake account farms, or scripts that post and comment automatically. PostSnag isn't built that way. It has no fake accounts, no proxies, no scheduled tasks, and no feature that acts on Facebook for you. The entire mechanism is: you scroll, PostSnag reads what's already there, and you decide when to export it.

Common questions

Does PostSnag ever post, comment, or message on my behalf?
No, never. PostSnag has no feature that takes any action on Facebook for you. It only reads and saves data.

Does PostSnag keep running after I close the Facebook tab?
No. Capture only happens on an open, active Facebook tab while you're scrolling it.

Does PostSnag check Facebook on a schedule, even when I'm not there?
No. There's no background polling or scheduled activity. PostSnag only reads what loads while you're actively scrolling.

If PostSnag isn't a bot, why does it need Facebook permissions at all?
It needs access to read the Facebook page you're already viewing, so it can capture what's on your screen. It doesn't use that access to take actions or run independently of you. See Why does PostSnag ask for the permissions it does?

Does the extension keep talking to PostSnag's servers while I browse?
No. Capturing only writes to your browser's local storage. The extension only contacts PostSnag's servers when you sign in or click Export To Dashboard.
