Privacy Policy
Effective 2 August 2026
Dukto Link does not collect, transmit, or store any personal data. There is no account to create, no analytics, no advertising, no tracking, and no third-party SDKs in the app.
Your files never reach us
Transfers go directly from one device to another over your local network. There is no server in the middle, and no copy of anything you send or receive is kept anywhere outside the two devices involved. Dukto Link has no backend, and the developer has no way to see what you transfer.
What stays on your device
The following is stored only on your device, and is removed when you delete the app:
- Your display name and avatar — how other Dukto buddies see you on the network.
- Recent transfer history — file names, sizes, dates, and the buddy involved.
- Your preferences — where received files and media are saved, and how multiple files are grouped.
- Received files — saved to the folder you choose, or to your photo library.
None of this is uploaded, backed up to a service run by the developer, or shared with anyone.
What is visible on your network
To find other devices, Dukto Link announces itself on the local network with the display name you set, your device’s hostname, and the platform (“iOS”). Any Dukto client on the same network can see this — that is how discovery works. Nothing leaves the local network.
Permissions the app asks for
- Local Network — required to discover Dukto buddies and to transfer to them. Without it the app cannot work.
- Photos — used only when you choose to send photos or videos, when received media is saved to your library, or when you open a saved item from Recent. The app does not browse or read your library otherwise.
- Notifications — optional, used to tell you when a transfer finishes or fails.
- Paste — when you tap Send from clipboard, iOS asks whether the app may read the clipboard. The contents are used for that one transfer and nothing else.
Security
Dukto Link is designed for trusted local networks. Consistent with the original Dukto protocol, transfers are not encrypted and there is no authentication beyond your choice of recipient. Use it on networks you control, and avoid it on public Wi-Fi.
Children
The app is not directed at children, collects no data from anyone, and contains no ads or in-app purchases.
Changes
If this policy changes, the updated version will be published on this page with a new effective date.
