How to send a file with an expiration date
Sometimes a file only needs to be available for a short handoff. MsgCrypt lets you attach it to an encrypted message and share a link with an expiration date instead of leaving a permanent attachment in an inbox.
Start an encrypted message
Write a short note explaining the file. Leave private details out of the optional title. The message and attachment are encrypted in your browser before they are uploaded.
Attach your file
Open Advanced options and select the file to attach. File size and storage limits depend on your plan; the form shows the limits that apply to your account.
Choose when access ends
Select an expiration date in Advanced options. You can also set a view limit. The message becomes unavailable when either limit is reached, so allow enough views for the intended recipients.
Send the full link
Create the message, then copy and share its complete link. Keep the part after the # intact: it is the key the recipient's browser uses to decrypt the content.
Expiration ends access to the original
A recipient can save a file after opening it. Expiring the message cannot remove downloaded copies or stop screenshots. If you need ongoing access control over a shared document, use a document service with individual account permissions.
What about privacy?
Anyone with the full message link can use its key while access remains available. Senders may see activity records when a message is opened. Review the privacy policy before sharing information that needs special handling. Read the privacy policy.
