Working From a Café: What the Wi-Fi Learns About Your Job

If you work from a laptop in Iran — designing, translating, writing code, keeping the books for a small shop — some part of that work happens on a network you do not own. A café in Tehran, a co-working desk in Isfahan, a relative's flat, a hotspot shared from somebody else's phone. The Wi-Fi is free, and nobody thinks about the router.

Open Means Open

Joining an open network puts your device on the same local segment as everyone else using it, and every packet you send crosses hardware operated by someone you have never met. Whatever is not encrypted end to end can be read there. Most of the modern web is encrypted — mail, banking, storage, the tools you file work through — so the contents of what you send are covered.

What Is Left Uncovered

The destinations are not. Each name your device looks up is visible to the network, as are the size and timing of every exchange. Over a single afternoon that produces a fairly complete picture: which client's storage you opened, which invoicing service you use, which repository you pushed to, when you started and when you stopped.

There is a second-order problem in freelance work specifically. A client's identity is often inferable from hostnames alone, and a confidentiality clause does not stop at the contents of the files. You would not hand a stranger that list on paper; an open network hands it over by default.

What a VPN Covers

A VPN puts all of it inside one encrypted connection between your device and a server you choose. The café's router sees a single stream to a single address. The list of destinations, the rhythm of the working day, the services you rely on — those stop being visible from the network side.

And What It Does Not

• It protects traffic in transit only. It does nothing about a laptop with something already on it, a phishing page you typed a password into, or an app that sends your data out by design.
• It does not make you anonymous. Your provider stops seeing your traffic and the VPN operator's handling of it becomes the thing that matters instead. Read the logging policy, and prefer a provider willing to state it plainly.
• It does not change what is permitted. It is a privacy tool, not a legal one.
• It is not a backup, not antivirus and not a password manager. Those are separate problems and it solves none of them.

Doft VPN

Doft VPN gives you every server location free, with no regions behind a paywall. It keeps no logs of your activity. One tap connects it on Android and iOS. The protocols it uses — VLESS with Reality among them — are current ones, chosen for modern cryptography and for staying up on connections that come and go. Premium buys higher speed and raises the data allowance; the privacy side is free, because a security tool that only protects paying users is not much of a security tool.
