DiskLink is a browser extension plus a small local agent that let websites
you explicitly approve read and write files inside folders you choose, on your
own computer.
In short: DiskLink collects nothing and
sends nothing anywhere. All file access happens locally, and only in folders
you approve for a specific website. There are no DiskLink servers, no
analytics, no tracking, and no accounts.
What DiskLink accesses
Files and folders you grant. When a website asks for
access, DiskLink shows a dialog where you pick a folder (or "all my folders")
and choose read-only or read-and-write. That site can then read or write
only inside the folders you granted it. System folders are always
blocked.
Every request is re-checked on your computer against what you approved.
What DiskLink stores
Your grants, saved locally in
~/.disklink-agent/config.json - which sites you approved, their
folders, permission level, and on/off state. This file never leaves your
computer.
File contents pass directly between the approved website
and your disk, through the local agent. DiskLink does not copy, log, upload,
or retain them.
What DiskLink does NOT do
No data is transmitted to the extension's authors or any third party.
No browsing history, page content, or personal information is collected.
No cookies, no advertising identifiers, no telemetry.
Permissions and why they exist
Runs on all sites (content script): so that any website
can offer the DiskLink option - but a site can do nothing until you approve
it in the dialog. The content script only relays messages between the page
and the extension; it does not read page content.
Native messaging: to talk to the local DiskLink agent,
which performs the actual file reads and writes on your machine.
Your control
Open the DiskLink toolbar icon at any time to see every approved site and to
change its folders, switch read-only/read-write, turn it off, or revoke it
entirely. Uninstalling the agent removes all stored grants.
