What Fairsend Can Do
Encrypted file transfer with proof of delivery, automatic deletion and full GDPR compliance — for individuals and teams.
Security & Encryption
End-to-End Encryption
Files are encrypted directly in your browser before they reach our servers. We cannot read or decrypt your data — not even upon official request.
All Plans
Zero-Knowledge Principle
The decryption key only exists in the download link and is technically never transmitted to the server. Fairsend has zero knowledge of your file contents.
All Plans
Automatic Deletion
Files are irrevocably deleted after the retention period — no backups, no shadow copies. Free plan: deletion right after the first download.
All Plans
Password Protection
Protect sensitive transfers with an additional download password. The recipient needs both link and password. Share them via separate channels for maximum security.

File Transfer
Drag & Drop Upload
Add files and entire folders via drag & drop — no account needed for your first transfer. Up to 5 GB free, up to 100 GB with Premium plans.
All Plans
Maximum Speed
Parallel transmission via multiple streams simultaneously. Interruption-safe: if the connection drops, the transfer seamlessly resumes where it left off.
All Plans
Email or Link
Send files by email to one or more recipients, or create a download link to share yourself. For email delivery, the sender is verified via a one-time code.
All Plans
Request Files
Create a secure upload link for third parties. They upload files encrypted to you — without their own account. Ideal for collecting documents from clients or partners.
From Premium
Tracking & Control
Real-Time Tracking
Each transfer has a unique tracking ID. Track the status in real-time — from creation to download. Email notification as soon as the recipient has downloaded the files.
All Plans
Proof of Delivery
After each download, a cryptographic integrity proof is automatically generated. The mathematical evidence that exactly these files arrived completely and unchanged.
All Plans
Custom Expiry Times
Set how long files should be available — from 24 hours to one year. After expiry: automatic, irrevocable deletion of all data.
From Premium
Geo-Lock
Restrict downloads to specific countries or regions. Ideal for compliance-relevant transfers.
Ab Creator+
Teams & Collaboration
Team Management
Teams with clearly defined roles: owner, admin, member, read-only. Email invitations, granular permission management, and central overview of all team transfers.
Team / Enterprise
Contacts & Address Book
Shared contact directory with colored groups. CSV import for large recipient lists. Send directly from the address book with one click.
Team / Enterprise
Four-Eyes Principle
Sensitive transfers require approval by a second person before delivery. Essential for regulated industries like finance, law and healthcare.
Team / Enterprise
Custom Branding
Your logo, your colors, your tagline on all download pages. Professional appearance for clients and partners — under your brand, powered by Fairsend.
Team / Enterprise
Modular Add-Ons & Audit Log
Expand your team flexibly: additional seats, storage or recipients — in configurable steps, scalable anytime. The audit log records every security-relevant action for internal compliance and external audits.
Team / Enterprise
REST API
Automate file transfers and messages via API. All transmissions are automatically encrypted with AES-256-GCM.
Team / Enterprise
File Storage
Temporary File Storage
Store files and folders encrypted temporarily. With expiration dates, folder structure, and the ability to send directly from storage.
From Premium
Encrypted Filenames
Not just file contents — filenames are also encrypted with AES-256-GCM in your browser. The server never sees the original name.
From Premium
Send Directly
Select files from storage and send them to recipients with one click via the familiar transfer form.
From Premium
Encrypted Messages
End-to-End Encryption
Messages are encrypted in your browser. Only the recipient can decrypt them.
All Plans
Self-Destruct
Messages self-destruct after reading. Immediately, after 1h, 24h, or 7 days.
All Plans
Link Mode
Share messages as an encrypted link — without sending an email.
All Plans
Compliance & Privacy
Hosting in Germany
Our entire infrastructure is operated in Germany. No data leaves the EU. No external cloud services.
