Question 1

What is SafeIn?

Accepted Answer

SafeIn is a secure file upload portal that lets anyone request encrypted file submissions from clients or contacts. The portal owner creates a shareable link; senders upload files directly through that link without needing an account.

Question 2

Who can use SafeIn?

Accepted Answer

Anyone who needs to collect sensitive files securely can use SafeIn — accountants, lawyers, real estate agents, healthcare providers, HR teams, and more. Senders do not need an account; they just use the shared link.

Question 3

How does SafeIn encrypt files?

Accepted Answer

SafeIn uses AES-256-GCM encryption combined with RSA-4096 key wrapping. Files are encrypted in the browser before upload using the Web Crypto API, so only the portal owner can decrypt them. The server never sees plaintext file contents.

Question 4

What happens to files after download?

Accepted Answer

Files are automatically deleted from SafeIn servers after the first download by the portal owner. They are not stored permanently.

Question 5

Do senders need to create an account?

Accepted Answer

No. Senders simply open the shareable portal link and upload files. No account, login, or password is required on the sender's side.
