What is SendOnce?

SendOnce is a free one-time sharing tool that turns a file into a single-use share link. The link you create expires and is deleted automatically after about 10 minutes, so it is valid only briefly once you hand it over and becomes inaccessible afterward. It is built for handing something to someone once, right now, rather than for long-term storage.

How to use

1. Tap "Select file" and choose the one file you want to send.
2. The file is uploaded temporarily and a share link is issued.
3. Copy the share link that was issued.
4. Share the link with the recipient through whatever reaches them, such as a messaging app or email.
5. The recipient opens the link and downloads the file within the valid period.
6. The link expires automatically about 10 minutes after it is issued, and the file is deleted.
7. After it expires, opening the same link no longer grants access. To send again, issue a new link.

Great for

• Handing something over once, right now

  When you want to quickly pass a document or image to someone in front of you or in a chat, a single link lets you hand it over fast.

• Sending to another device

  To move a file from a PC to a phone or to another of your own devices, just open the link to grab it, with no cable or account linking needed.

• Sharing for only a short time

  For temporary files you do not want lingering around, you can hand them over with a link valid for only about 10 minutes, so nothing stays shared indefinitely.

• Handoffs you do not want left in the cloud

  When you want to avoid leaving a file in a shared folder and forgetting to delete it, an auto-expiring one-time link is handy.

• On the spot in meetings

  It suits temporary sharing where you hand materials to someone in person or online and want them to disappear automatically when you are done.

• Quick, with no sign-up

  It helps when you want to open the page and create a link right away, without going through account registration or app installs.

Privacy

The file you share is uploaded temporarily to Firebase Storage as a one-time share that expires and is deleted automatically after about 10 minutes. Only someone who knows the share link can download it within the valid period, and access ends once it expires. It is a tool intended for one-time handoffs, not for long-term storage.
