What is link expiry?

Link expiry is a setting that gives a share link a lifespan. You pick a date, and after it passes the link stops serving the file and shows a clear expired message instead. It turns a permanent share into a temporary one, which is exactly what you want for anything that should not linger online. A link that works forever is convenient for a portfolio and a liability for a contract.

The sensitive-document case is where this earns its place. A sales agreement, an NDA, a medical form, or a financial statement should be openable for as long as the deal is live and not a day longer. Set an expiry and the link closes itself, so you do not have to remember to delete it. This pairs naturally with how password protection works when you want both a lock and a deadline, and it is useful even for everyday sharing like the flow to send a large PDF without email, where you may want a big file to stop being reachable after the recipient has it.

Under the hood this builds on signed, time-limited access, so expiry is enforced rather than cosmetic. You can also just delete a link at any time, which revokes access immediately. Hosting is free to start, and upgrade to Pro carries the controls you need across more files. The point of expiry is control after sending. The share ends on your schedule, not whenever you happen to remember it.
