info Short version: Linko doesn't collect your files, doesn't track you, and doesn't have any accounts. Your files go directly to the other device — we never see them.
person_off No accounts, no sign-ups
Linko doesn't ask you to create an account, enter an email, or fill in any personal information at all. You just install it and start sharing — that's it. There's nothing to register.
The app does generate a random device fingerprint (a UUID) so nearby devices can recognize each other. This ID is stored only on your device and is never sent to any external server.
folder_off Your files stay between you and the recipient
When you send a file through Linko, the transfer goes directly from your device to the recipient's device — not through our servers, not through any cloud service, nothing in between.
On a local network (same Wi-Fi or hotspot), the connection is purely peer-to-peer using your local IP address. For transfers across different networks, we use WebRTC — which means our server only helps both devices "find" each other (a process called signaling). Once that handshake is done, the server steps out and the actual file transfer happens directly between the two devices.
We never see, store, or have access to any file you send or receive.
analytics_off No tracking, no analytics
There are no analytics SDKs, no crash reporters phoning home, no ad networks, and no third-party trackers in Linko. The app is open source — you can verify this yourself by reading the code on GitHub.
We don't collect or retain:
- What files you share or receive
- Who you share with
- How often you use the app
- Your location or IP address (beyond what's technically needed for a WebSocket connection)
- Any behavioral or usage data whatsoever
security How your transfers are protected
On local network transfers, data is encrypted end-to-end with TLS certificates generated locally on your device. For cross-network transfers via WebRTC, the connection is protected by DTLS (the WebRTC standard for encryption). In both cases, no one in the middle — including us — can read the contents of your transfer.
cloud Third-party services we use
To make cross-network transfers work, we run a small signaling server on Cloudflare Workers. This server only handles the WebRTC handshake — it sees the WebSocket connection metadata (like your IP) for a few seconds while both devices are negotiating, and nothing after that.
We also use Google's STUN servers to help with NAT traversal (figuring out how two devices on different networks can reach each other). This is standard WebRTC infrastructure and doesn't involve any data from your files.
Relevant third-party policies:
child_care Kids and age restrictions
Linko is a general-purpose file sharing tool with no age-restricted content. Since we don't collect any personal data at all, there are no special considerations for younger users beyond what applies to everyone.
update Changes to this policy
If we ever change how Linko handles privacy — for example, if we add a new feature that involves some kind of data collection — we'll update this page and note the date at the top. We'll also mention it in the app's changelog.
We don't plan on collecting user data, but if that ever changes, you'll be the first to know.
