Yes, at session level, and the mechanism is delivery itself. Your player asks the server for a specific stream, then keeps asking for the next six-second segment until you stop, so the account, the channel and the duration are all part of the request. Nothing exotic is needed to record that. A cable box reports similar information back over the same wire, and every on-demand app logs the title you opened. What a service cannot see is your screen, your other browsing, the rest of your household's traffic, or anything you play from another source. Visibility ends at what its own servers delivered.

Because a limit is arithmetic. Plans here allow 1 to 5 simultaneous streams on unlimited installs, and enforcing that means the server knows how many sessions an account has open right now, and releases a slot when playback stops. That is the same record showing which stream was open. If a service advertises a connection cap and also says it counts nothing, one of the two statements is inaccurate. The useful question is not whether records exist but what happens to them: how long they are kept, whether they are tied to a stored payment card, and how much information opening an account required in the first place.

Different things, and less than people assume. An ISP sees which server addresses your connection talked to, when, and how much data moved. Modern transport is encrypted, so the picture, the channel name and the guide are not readable along the way. Volume is still a signal: 4K runs about 15-25 Mbps and roughly 7 GB an hour, 1080p about 5-8 Mbps and 3 GB an hour, and several hours of that every evening looks like video whatever the destination. That traffic shape is identical for any streaming service, which is why it identifies almost nothing about what you chose to watch.

It moves one boundary and leaves the other alone. A VPN hides destination addresses and traffic volume from your internet provider, and it hides your home address from the service, which now sees the tunnel's exit point instead. It does not hide the account. You are still signed in, so which stream you opened is still attached to your subscription. A VPN also changes nothing about licensing, which attaches to individual services rather than to the delivery method: television over internet protocol is a transport, and the rights position depends on the specific service and your jurisdiction. Expect a bandwidth cost too, since encryption and a longer path eat headroom.

More than the technology suggests. Use a dedicated email address for the subscription so the account is not linked to everything else you own. Prefer a service that stores no card, as none is kept here, because a stored card is the most durable identifier most accounts carry. Check renewal behavior: nothing here renews automatically, so a forgotten account does not keep transacting. Ask in writing how long session records are kept and who can read them, because a service that cannot answer plainly has told you something useful. And keep separate profiles or devices per viewer where the player allows it, so viewing is not pooled into one record.

1. 1A dedicated signup email limits what the account is linked to
2. 2No stored card removes the most persistent identifier
3. 3Ask about record retention in writing, before paying
