How it's funded
Free, funded transparently — no catch buried in the fine print
Every other document converter either charges a subscription, caps you at three files a day, or stamps a watermark on the way out. BizTray does none of those. It’s free because it shares a portion of your internet bandwidth in the background — and we’d rather explain exactly how that works, including the parts you might not like, than hope you never ask.
No account. No subscription. No ads, no upsells, no page limits, no watermark. Just a plain exchange: you get seven document tools with no quota, and in return a partner service relays some of its traffic through the internet connection you're already paying for. It keeps doing that while the app is installed — including after you close the window — until you turn it off or uninstall.
Why it's free
An exchange, not a subscription
The usual way
Upload your document to a stranger's server, wait in a queue, and hit a limit — three files an hour, 10 MB a file, a watermark unless you pay. The bill never really stops, and neither does the uploading.
The BizTray way
The work happens on your machine, so it costs us nothing per file — which is why there is no quota to enforce. What covers building and maintaining the app is a share of the bandwidth you're already paying for. That's the whole deal, and it's the reason we can say no to the subscription.
The bandwidth sharing is powered by the Massive SDK, a partner that runs a legitimate bandwidth marketplace — businesses pay for access to residential connections for things like price comparison, ad verification, and web data collection. Your share of that is what keeps BizTray free.
In plain terms
What “sharing bandwidth” actually means
No jargon. Here's what does and doesn't happen on your machine.
What it is
- A portion of your internet connection is used to relay other parties’ web traffic — the way a lot of “free” apps quietly keep the lights on, except we say so.
- It runs in the background and keeps going after you close the window, while you’re signed in to Windows, until you turn it off or uninstall.
- The traffic is other companies’ ordinary web requests passing through — not something you host, store, or are responsible for.
What it isn’t
- Not access to your documents. The files you convert, sign and organise are read by BizTray on your own machine and are never part of this — and nor are your browsing history, credentials, keystrokes or screen.
- Not a background miner or something that hammers your CPU — this is about bandwidth, not grinding your machine.
- Not something that pauses itself. There is no metered-connection detection and no automatic back-off while you’re busy, because those aren’t in the build. If you want it to stop, you stop it.
What it touches
What the partner sees, and what it never does
Disclosed at install, before anything runs — no dark patterns, no pre-ticked boxes, and no surprises to discover later.
Never your documents
It does not read, upload or share your files, the documents you process, your browsing history, the sites you visit, your credentials, cookies, keystrokes or screen contents. It relays other parties' traffic.
What the partner does process
To route traffic, Massive processes your IP address during active sessions, an anonymous device identifier, city-level location, device specifications, and bandwidth statistics — held for up to 60 days, under its own privacy policy as an independent controller.
It runs in the background
The agent starts with your Windows session and keeps sharing after you close BizTray, until you turn it off or uninstall. It shares only for the signed-in user — not system-wide, and not at the sign-in screen.
Disclosed at install
The exchange is spelled out plainly when you set BizTray up, and the app shows a status indicator while sharing is on. Massive's own tray icon can stop it too, and a stop from there is honoured.
Switchable off — at a cost
A clearly-labelled toggle in Settings, the tray menu, or Massive's tray icon turns sharing off. The tools don't run while it's off: that is the trade the free app is built on, and we'd rather say it here than let you find out.
Your control
Turning it off, and what that costs
You can stop sharing at any time — from BizTray’s Settings, its tray menu, or Massive’s own tray icon, and a stop from there is honoured rather than quietly restarted. But be clear about the trade: the tools don’t run while sharing is off. The exchange is what makes the app free, so switching it off pauses the thing it pays for.
And if you’d rather have none of it, uninstalling is the complete opt-out — it stops and removes the partner agent entirely. No retention screens, no “are you sure?” guilt trips, no hoops. We would genuinely rather you left cleanly than stayed on terms you’re not happy with.
Privacy
What leaves your device — and what never does
All seven BizTray tools — the conversions, the PDF organising, the watermarking and unlocking, Fill & Sign — run entirely on your machine. The documents you open, the folders you watch, and the files you produce stay on your device. They aren’t uploaded to us or to anyone else.
The bandwidth sharing carries the partner’s web traffic — not your documents, not your browsing history, not anything you do in the app. To run the network the partner does process some device data, such as your IP address and coarse location; that is covered in the Privacy Policy below. We don’t sell your data, and we don’t build a profile of you.
For the full detail on what’s collected and why, read the Privacy Policy.
