In brief
We use cookies and browser storage that are necessary for what you yourself request: staying signed in, remembering your language or remembering a discount code. No consent is required for this. We do ask two things first, off by default: statistics with Google Analytics, and advertising: measuring which ads on Facebook and Instagram bring visitors, with the Meta pixel. You can always change your choice here. For signing in with Google, see below.
Your choice
Nummo cookies

In production, some cookies carry the prefix __Secure-. For Nummo administrators there is one additional security cookie on the administration pages.
Storage in your browser
Your browser itself stores some preferences (localStorage and sessionStorage). They stay on your device; Nummo does not read them on the server.
| Key | Purpose | How long |
|---|---|---|
| nummo:recent | The last profiles you viewed, for the "Recently viewed" list | until you clear them |
| nummo-weergave | Light or dark theme and other display preferences | until you clear them |
| nummo-publicaties-weergave, nummo-bestuur-weergave, nummo-gezond-tab, nummo-meer-gegevens | Which tab or view you last chose | until you clear them |
| nummo-check | The text you pasted into the free bankruptcy check | until you clear it |
| nummo-extensie, nummo-installeer | Whether you dismissed the invitation for the extension or the app | 30 or 60 days |
| fichr-vergelijk, nummo-fiches, nummo-onetap, nummo-email | Temporary, in the same tab: businesses you want to compare, the profiles you viewed (for signing in with Google), and your email address if you go from signing in to forgotten password | until you close the tab |
Measurement without cookies
We anonymously count which pages are viewed using Vercel Web Analytics, without cookies and without following you across sites. We measure how the site is used with PostHog in the European Union, also without cookies and without storage in your browser: you are not recognised on a subsequent visit. More on this in our privacy statement.
Statistics with Google Analytics
Only if you allow statistics does your browser load Google Tag Manager and Google Analytics. Google then places the cookies _ga and _ga_<id> (up to 13 months) to count visits. We only send the type of page you view (for example "profile" or "search") and which buttons you click, never enterprise numbers, names of businesses or persons, or what you search for. Advertising signals are off. If you withdraw your consent, we delete those cookies.
Advertising with the Meta pixel
Only if you allow advertising does your browser load the Meta pixel of Meta Platforms Ireland. Meta then places the cookie _fbp (90 days), and _fbc (90 days) if you arrived through an ad on Facebook or Instagram. This shows us how many visitors an ad brought. We only send a page view on pages without a company, person or search (such as the home page, prices or a barometer), never enterprise numbers, names or what you search for, and no data about you such as your email address. Meta may add information from the page itself to that page view, such as the title and description. Automatic measurement of buttons and forms is off. Nummo and Meta are jointly responsible for collecting and passing on data through the pixel; what Meta then does with the data falls under Meta's privacy policy. If you withdraw your consent, we delete those cookies.
Signing in with Google
If you are not signed in and view a second business, Google may show a small window to sign you in with one click (Google One Tap). Your browser then loads a script from Google; Nummo itself places no cookies for this. Google uses its own cookies for this, which are already present if you are signed in to Google; this is governed by Google's privacy policy. Nummo receives nothing from Google until you yourself click continue. If you dismiss the window, it stays away for a while. It does not appear on the sign-in pages, your profile or the pricing page.
Business logos
Your browser sometimes loads a business's logo directly from its own website, from Wikimedia or from Brandfetch. As far as we know, those sites do not place cookies via Nummo in doing so, but they do see your IP address, as with any image on the internet.
Chrome extension
The extension does not use cookies. It stores your settings and the "Recently viewed" list in the extension's storage in your browser.
Refusing or deleting cookies
You can delete or block Nummo cookies and storage in your browser at any time. Without the sign-in cookie you cannot sign in, but searching and viewing profiles still work. Without the language cookie you choose your language again each time.
