It is important to share personal and sensitive content, such as travel photos, family videos and even confidential business documents, securely. Follow the guide below to learn how Samsung Private Share works to protect you and your data.
What is Private Share?
Private Share is a privacy-preserving file sharing function that allows you to share your data without concerns of Invasion of Privacy and loss of ownership. When you deliver your files through Private Share, your files are securely encrypted, and you, the owner of the data, can set permission and expiration date for the data and grant read-only access.

How to send files through Private Share
Private Share uses blockchain-based encryption technology. Through Private Share, content is encrypted before delivery. The sender can control the recipient’s access and can see when the recipient received and opened it. You can share up to 10 files at once, but the total size needs to be less than 20MB.
Step 1. Select the file you want to send, and then tap the Share icon.
Step 2. Tap Private Share, then designate the person you want to send it to Private Share.
Alternatively, you can go to Settings > Biometrics and security > Private Share.
Step 3. Choose how to invite (Send using SMS, Send using QR codes, Send in other ways)
Step 4. After sending the files, you can check the files you sent.
Step 5. You can also select a shared file to change the expiration date or revoke sharing permission.
Once the recipient receives the file, they receive a notification that there is a new item via Private Share. Received content can only be viewed within Private Share as read-only, so it cannot be captured or saved, nor can it be transferred externally.
If the sender revokes sharing, the recipient can no longer access the data.
Step 1. Tap the received notification.
Step 2. Tap Accept to start file sharing on Private Share.
Step 3. Select the file you want to view on the received file list.
Step 4. You can see the contents you downloaded, file history, and expiration date.
