This notice covers the ZeroH Disclosure plugin, this website and its waitlist. It is written to be read, not skimmed past.
Last updated 26 September 2026
In short: the free plugin sends us nothing. This website sets no cookies and runs no analytics. If you join the waitlist, we keep your email address and the products you picked, only to tell you when they open, and we delete them when you ask.
Who we are
Blade Labs Holdings Private Limited (“Blade Labs”, “we”) decides how this information is used. Write to hello@bladelabs.io about anything on this page; a person answers.
The ZeroH Disclosure plugin
It runs on your computer. Your secrets, the token map, the vault and your receipts stay on your disk, under ~/.zeroh (%LOCALAPPDATA%\ZeroH on Windows).
It sends nothing to Blade Labs: no account, no telemetry, no crash reports. Its only network traffic is Claude Code's own requests to your model provider, which pass through its local proxy, and the commands you run.
A missed-value report stays on your computer. It holds the value's type, length and where it appeared, never the value. Sending one to us is planned as a separate choice you make each time.
Claude Code and your model provider handle your conversation under their own terms. The plugin reduces what they receive; it does not change those terms.
This website
No cookies and no analytics.
Your browser remembers your light or dark choice, and on the test guide which shell tab you picked, in its own storage. It never leaves your browser, and clearing your site data removes it.
The site is hosted on Microsoft Azure Static Web Apps in the West Europe region. Like any web host, Azure processes the technical data needed to deliver a page, such as your IP address.
The typeface (Inter) is served from this site too. Your browser requests nothing from Google or any other font service.
Videos and pictures are served from this site; nothing is embedded from other services.

Your choices
Write to hello@bladelabs.io from the address you signed up with to see what we hold about you, correct it, or have it deleted. We reply within 30 days. If you think we have handled your data wrongly, you can also complain to your local data protection authority.
Changes
If this notice changes, the date at the top changes with it. We will not use what we already hold in a new way without asking you first.
