SettingWhat it does
Expiry dateSets how long the download link stays active. Defaults to 7 days on free tier; unlimited on paid plans.

Send the transfer

Click Send. Sinosend encrypts your files with AES-256 and uploads them to your chosen data center. Each recipient immediately receives an email containing a secure, unique download link.
Large files may take a moment to upload depending on your connection speed. Keep the browser tab open until the upload completes and you see the Transfer Sent confirmation.

Track delivery from your dashboard

Open the Transfers tab in your dashboard to monitor your delivery in real time.
  • Delivered — the email was successfully sent to the recipient.
  • Opened — the recipient clicked the link and viewed the transfer page.
  • Downloaded — the recipient downloaded one or more files.
Click any transfer to see a full activity log, including timestamps and geolocation data showing where the download occurred.
Enable browser notifications in your account settings to get instant alerts the moment a recipient opens or downloads your transfer.
