Privacy & Analytics
Speed to Power is a public map of the Dutch electricity grid, plus a Battery Screener for registered users. This page explains exactly what data we process, why, and the choices you have. In short: the map needs no account, our analytics set no cookies, and we never sell or share your data.

What we collect
To understand how the product is used and to fix problems, we run product analytics from PostHog. We record page views, anonymous interaction events (such as which map layers and filters you open), and masked session replays of the interface.
You do not need an account to browse the map. Creating an account is only required to run the Battery Screener.
No cookies, no tracking
Our analytics keep all state in memory for the duration of a single page load. We set no cookies and write nothing to your browser's local storage, we do not track you across other websites, and we serve no advertising. That is why you see no cookie-consent banner.
Anonymous by default
We do not build a personal profile for anonymous visitors. Analytics events are only linked to you after you identify yourself — for example by creating an account or sending feedback with your email address.
Session replays mask all text and form inputs by default, so the contents of fields you type are never captured.
Where your data is processed
Analytics are processed by PostHog in the European Union (PostHog's EU Cloud). Browser traffic is routed through our own server (a same-origin proxy) before it reaches PostHog, so your requests stay on our domain. Your analytics data stays within the EU/EEA — there is no transfer outside the European Economic Area.
Account data
If you create an account, we store your email address and authentication details with Supabase to provide and secure the Battery Screener. We use this only to operate your account.
Your rights
Under the GDPR (in the Netherlands, the AVG) you can request access to, correction of, or deletion of your personal data, and you can object to processing. Because anonymous analytics carry no identifier we can trace back to you, these rights mainly concern account data.
To exercise any of these rights, contact us using the feedback button in the app header. We respond within one business day.
Changes
We update this page when our data practices change, and revise the date above accordingly.
