NOBODY
Temporary File Sharing
A file you sent last year is still a file someone can open today. Temporary sharing fixes that by giving every transfer an end date at the moment it is created.
Pick an expiry that matches the errand
1 hour suits a handover happening right now — a document for someone standing next to you, or a print shop about to run the job. 6 and 24 hours cover the rest of a working day. 7 days is the longest a NOBODY share can live.
The countdown starts when the share is created, not when it is first opened, so the window is predictable.
Self-destructing shares
When the expiry passes, the code stops resolving and the stored files are removed. The same happens when a download limit is reached, which is what makes a one-download share effectively self-destructing.
Nothing can revive an expired share — not the code, not the link, not the QR poster. If the file is still needed, upload it again with a fresh code.
Why time limits are a privacy feature
Every copy that outlives its purpose is a copy that can leak later. An expiry keeps the amount of shared data small by default instead of relying on someone remembering to clean up.
Combine it with a PIN and a download limit when the content deserves all three.
