Help & Support

1. Open the homepage and drag files into the upload area. You can also click "Files" or "Folders".
2. While the files upload, confirm the three notices and click “Accept & continue to send”.
3. Choose "Send by email" (enter the recipient's address) or "Create link only" (share the link yourself).
4. For email delivery: enter your sender address and confirm with the 6-digit code.
5. Your files are encrypted and uploaded. You receive a tracking ID and the download link.

Without a subscription you can send one transfer per day of up to 5 GB, recipients per transfer: 1. The files stay available for 7 days and are deleted after the first download.

Go to page

1. Open the Dashboard.
2. Click the three-dot menu next to the transfer.
3. Choose “Copy full download link” or “Copy link and key separately”.

With “Copy link and key separately” you get the link without the key and the key on its own. Send them through different channels, for example the link by email and the key by text message. The recipient opens the link and enters the key in the “Enter key” field.

This works for signed-in senders. For team transfers, team owners and admins can also copy the links.

Turn on password protection when you create a transfer. The recipient has to enter the password before downloading. Send the password through a different channel than the link, not in the same email.

Before sending, switch on the "Password protection" option and set a password with at least 10 characters, or have one suggested. Your browser uses it to wrap the key of the transfer. Fairsend stores neither the password nor the key. Share the password separately from the link. Password protection is available from the Premium plan.

Copied links and team access contain no key, and a lost password cannot be recovered. Older transfers with an access code or password remain available unchanged.

Go to page

Without a subscription a transfer stays available for 7 days. From Premium you choose a duration under “Expiry & Downloads”, between 24 hours and the maximum of your plan, or a custom duration in days. The period starts when the transfer is sent. After that all files are deleted automatically.

There you also set how often the files may be downloaded. Once all recipients have downloaded and the allowed number is reached, the files are deleted one hour later.

Open “Track” and enter the Tracking ID and the email address of the sender or a recipient. You see the status, the expiry date and whether the files have been downloaded.

Ready: The recipient can download. Delivered: The download link has been opened. Downloaded: The files have been collected. Expired or Deleted: The files are no longer available.

Go to page

For every download, Fairsend records the time, IP address and recipient and combines them with the file checksums into a SHA-256 value. You open the full proof in the Dashboard via the transfer's menu or via the link in the notification. Other people only see a verification view without personal data.

Whether you receive an email on the first download per recipient is set under “Settings”.

1. Open the Dashboard.
2. Click the three-dot menu next to the transfer and choose “Delete”.
3. Confirm the prompt.

The files are deleted immediately and the download link stops working. This cannot be undone. The transfer stays in your overview with the status “Deleted”.

Go to page

1. Open “Request”. You need to be signed in for this.
2. Choose “Create link only” or “Send via email” and enter the email address if needed.
3. Click “Create upload link” or send the request.

The person you ask uploads their files via the link and does not need an account. From Premium you can protect the upload link with a password.

Go to page

Select the allowed regions when sending. A download only works if the recipient's IP address is in one of those regions. All other attempts are blocked.

When sending, enter the email address of the person who should approve. They get an email with Approve and Reject buttons. The transfer is only delivered after approval, and we let you know the result by email.

Approval is only available when sending by email.

Open the link you received by email or directly from the sender. Tick the usage confirmation and click "Download securely". The files are downloaded encrypted and are only decrypted in your browser.

With several files you can choose between a ZIP archive and individual downloads. If a large download is interrupted, it continues automatically.

For very large files, depending on the browser, you are asked where to save the file before the download starts, and the file is written directly there.

After the # sign comes the key your browser uses to decrypt the files. So always copy the complete link. If the sender sent you the link and key separately, open the link and enter the key in the “Enter key” field.

You get the password from the sender, usually through a different channel than the link. After five wrong entries, input is blocked for one hour.

"Transfer expired": The retention period has ended and the files have been deleted. Ask the sender to send the files again.

"Decryption key missing": The download link is incomplete. Make sure you copy the whole link, including the part after the # sign.

“Regionally restricted”: The sender has limited access to certain countries. Please contact the sender.

Download does not start: Check that your browser supports JavaScript and the Web Crypto API. Current versions of Chrome, Firefox, Safari and Edge do.

1. Open the upload link from the email or from the person who asked.
2. Enter the password if one is required.
3. Select the files and complete the upload.

You do not need an account for this. The person who asked is notified as soon as your files are ready.

File Storage is your encrypted storage for a limited time. Files are deleted automatically when the retention period ends. Fairsend is not an archive.

File Storage is available from Premium. It uses the same storage as your transfers.

Go to page

That depends on your plan: Premium: 30 days, Creator+: 90 days, Team: 365 days, Enterprise: no expiry.

Yes. In a file's menu, choose “Change expiry”. The new date can be at most as far in the future as your plan allows. You receive an email three days before expiry. After expiry the files are permanently deleted.

Yes. In your File Storage, turn on “End-to-end with your own passphrase”. The server then stores the storage key only wrapped with your passphrase and with a recovery code; you unlock your storage in the browser. Fairsend cannot decrypt files and file names you upload after that. The server can still see folder names, sizes and file types. You see the recovery code only once. If you forget the passphrase and lose the code, the files are lost. You can turn the feature off again at any time.

Go to page

Yes. Select the files and click "Send". The usual transfer form opens.

Yes. Files are encrypted in your browser with AES-256-GCM before they are uploaded and stored only in encrypted form on servers in Germany. Fairsend manages the file storage keys for your account so that you can access your files from any device you are signed in on.

With Fairsend you can send encrypted text messages, by email or as a link. The message is encrypted in your browser before it is sent.

1. Open “Messages” and click “New message”.
2. Choose “Send via email” or “Generate link only”.
3. Enter a subject and message and click “Send encrypted”.

Without a subscription you can send up to 5 messages per day.

Go to page

“Destroy after reading” is on by default. As soon as the recipient opens the message, it is deleted from the server. Until then it stays stored. You can delete a message yourself at any time with “Destroy now”.

If you turn the option off, you set how often the message may be read and when it expires. The maximum duration depends on your plan.

In “Generate link only” mode you receive a link after sending that you can share through any channel. Later you can copy it in the message list with “Copy reading link”, as long as the message has not been destroyed.

Go to page

From Premium you can also protect messages with a password. Geo-lock and four-eyes approval are also available in the plans that include these features.

1. Go to Teams and click "+ Create Team".
2. Enter a name and optionally a description.

Teams are available from Team. You can create up to five teams of your own.

Go to page

1. Open the team and enter the email address under “Invite member”.
2. Choose the role and send the invitation.
3. The invited person accepts the invitation via the link in the email. The link is valid for seven days.

Owners and admins can invite members; only the owner can invite admins. To invite several people, use the CSV import.

Owner: Full access to members, branding, add-ons and billing, can delete the team.

Admin: Manage members, contacts, branding, settings. No access to billing.

Member: Create transfers, manage contacts, view transfers.

Read Only: View team overview and transfers, no own actions.

1. Open the team and click “New Transfer”.
2. At the top it says “You are sending as team” with the team name. With “Send privately” you switch to a personal transfer.
3. Select files and recipients as usual and send.

Team transfers use the features of the team owner's plan. Owners and admins see all of the team's transfers.

Under “Team Defaults for Transfers”, owners and admins set which settings new team transfers start with: expiry period, number of downloads, “Team Members Only” and allowed countries. These values can be changed when sending.

If “Password Required” or “Four-Eyes Principle Required” is switched on, these options are locked when sending, with the note “Required by your team”. With mandatory approval, only sending by email is possible. Team owners and admins can approve, the sender cannot.

In the Contacts tab you can save recipients, organize them with colored groups, and import via CSV. Click the send icon next to a contact to start a transfer directly.

Owners and admins add a logo, colour and slogan in the team settings. Recipients see them on the download page of every team transfer. This requires the team owner to have a plan with branding (from Team).

The owner books additional seats in the team settings under “Modular Add-Ons”. When you buy, you pay pro rata until the end of the current period; after that the add-ons renew with the subscription. Under “My plan & add-ons” you cancel each add-on individually at the end of the period.

Under Account you can change your name, email and password. You will also see your plan and storage usage there, and you can export your data or delete your account.

2. Choose the authenticator app and scan the QR code with the app.
3. Enter the six-digit code from the app and click “Activate”.
4. Store the eight recovery codes in a safe place. Each code works once in place of the app code.

Instead of the app, you can also have the codes sent to you by email (“email codes”). Accounts with admin rights use the authenticator app only.

Go to page

When asked for the code, tick “Remember this device for 90 days”. Fairsend then does not ask for a code in this browser for 90 days.

In your account under “Remembered devices” you remove individual devices or sign them all out. Changing your password and setting up 2FA again or turning it off also sign out all devices. This feature is not available for admin accounts.

When asked for the code, click “No access to your device?” and then “Send code via email”. The code is valid for ten minutes, and you can request up to three codes per hour. Alternatively, enter one of your recovery codes.

After five wrong entries within 15 minutes, sign-in is blocked for 15 minutes. Without the app, admin accounts can only sign in with a recovery code.

On the sign-in page, click “Forgot password?”, enter your email address and open the link in the email. The link is valid for one hour.

Your files are encrypted in your browser with AES-256-GCM before they reach our servers. On our servers in Germany they are stored only in encrypted form. When the retention period ends, they are deleted automatically.

Go to page

Decryption requires the key from the download link. Fairsend stores this key encrypted on the server so that you can copy links again later. The files are decrypted in the recipient's browser.

The exception is transfers with password protection: Fairsend stores no key for them.

Exclusively in Germany. We use no cloud services and no external CDNs and transfer nothing to third countries. Only if you come via a Google ad and agree during checkout do we report the purchase to Google. In your profile settings you can export your data or delete your account at any time.

Files are deleted automatically when the period expires. We delete logs with IP addresses after 90 days. Proofs of Delivery are anonymised after the period of your plan: Free: 90 days, Premium: 90 days, Creator+: 90 days, Team: 180 days, Enterprise: 365 days.

You can report suspicious transfers with the tracking ID. We review every case. After several reports, the transfer is blocked automatically.

Every download page has a “Report abuse” link for this.
