What this site is

DarkMatterDB is an Onitsoga Labs directory of Matter hardware listings from the CSA Distributed Compliance Ledger (DCL). It is not CSA, not a certification body, and not an Amazon store.

These pages sit with the Terms of Service and the affiliate disclosure.

No accounts

This site does not offer accounts, profiles, or a login. Browsing the catalog does not require your name or email. The contact form is the exception: if you write to us, we ask for a name, email, and message.

What stays on your device

The compare tray is stored in your browser with the localStorage key mm_compare. First-visit guidance toasts may use other localStorage keys so they do not repeat. Clearing site data for this origin removes them. We do not upload the tray.

Cloudflare logs

The site is hosted by Cloudflare. Cloudflare may log request metadata used to operate the service (for example IP address, user-agent, URL, and timestamps). Search queries can appear in those logs. We do not sell that data. We store catalog data to operate the directory.

Amazon and cookies

DarkMatterDB does not set advertising cookies of its own. Buy links, when shown, go to Amazon. If you follow one, Amazon may set its own cookies and process the visit under Amazon’s policies. See the affiliate disclosure.

Listing facts

Device identity and certification status come from the CSA DCL. Product photos, when present, come from manufacturer pages (or a hotlinked Amazon image URL). We do not invent cert IDs or ASINs.

Children

DarkMatterDB is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child provided information through this site, contact us and we will delete what we can.

We do not sell personal information

We do not sell or share personal information for cross-context behavioral advertising. There is no account profile to download. Request logs are retained only as needed to operate the service.
