Frequently Asked Questions

Perkoon FAQ

Is the P2P transfer really free forever?

Yes, absolutely! The peer-to-peer transfer technology creates a direct connection between browsers. Since your file data never passes through or is stored on Perkoon's servers, it costs us essentially nothing to provide. We promise that core P2P functionality will remain free, unlimited, and without mandatory accounts forever. That's our whole deal!

What happens if the recipient is offline?

If your recipient isn't online for a direct P2P transfer, Perkoon can hold the file for them using our encrypted cloud storage. This is a paid feature because storing data on servers incurs real costs for us. The file is securely encrypted and held until they are ready to download it, ensuring your transfer is successful no matter what.

Can Perkoon see what I'm sending with P2P?

No, we cannot! During a peer-to-peer transfer, the file data is streamed directly between the two browsers involved in the transfer. It is encrypted end-to-end and never passes through our infrastructure. We literally have no way to see, scan, or access the contents of your P2P transfers. Your privacy is guaranteed.

How can AI agents or scripts use Perkoon?

Easily! Perkoon is built with automation in mind. We expose a clean JavaScript object (window.__perkoon) on our web interface that AI agents and scripts can interact with directly to initiate and manage transfers programmatically. This eliminates the need for unreliable DOM scraping and makes Perkoon a native tool for automated workflows.
