Privacy
Last updated: 18 October 2026
Short version: DataLayer Spec runs entirely in your browser. The spec you build is stored on your own device and never uploaded to us. We load no analytics. The only personal data we keep is the email address you confirm to get access.
Who we are
DataLayer Spec is a free tool provided by New North Digital (“NND”, “we”), an analytics consultancy based in the Netherlands. For any privacy question, email hello@newnorth.nl.
What the tool stores, and where
Everything you do in the tool happens client-side. The event spec you build is saved in your browser’s localStorage and encoded into the page URL so you can bookmark or share it. This data stays on your device (and in any link you choose to share). It is not transmitted to, or stored on, NND servers.
To clear it, use your browser’s “clear site data” for this site, or the “Clear all” action in the tool.
Access with your email address
To use the tool you enter your email address, open the link we send to it and press the confirm button. We ask for this so we know who uses the tool. Until you confirm we do not add you to any list: the address is used to send that one email, and our email provider keeps its usual log of the email it delivered.
When you confirm, your email address is stored in Resend, our email provider, whose sending domains for New North Digital are configured in the EU region, as a contact on the New North Digital updates list, and we receive one notification email saying that you signed up. We may send occasional updates about the tool and our work. Every email contains an unsubscribe link, and you can also ask us at hello@newnorth.nl to delete your address.
Confirming also sets one cookie (dls_access) that keeps this browser signed in for a year. It holds your email address and an expiry date, signed so it cannot be altered. It is needed for the tool to work and is not used for tracking.
Hosting
The site is hosted on Vercel. As our hosting provider, Vercel processes standard technical request data (such as IP address and request metadata) in server logs to deliver and secure the site. See Vercel’s own privacy notice for details.
Feedback emails
The “Send feedback” button opens your own email client with a draft addressed to hello@newnorth.nl. If you send it, we receive whatever you choose to include (which may contain your spec URL and browser details) and use it only to respond and improve the tool.
Your rights
Under the GDPR you have rights of access, rectification, erasure, restriction, and objection regarding any personal data we hold. This is relevant to the email address you confirm for access and to feedback you email us; the tool itself collects nothing else. To exercise a right, contact hello@newnorth.nl. You may also lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
Changes
We may update this notice as the tool evolves. The “last updated” date above reflects the current version.
