What cookies we use and how to control them
Last Updated: November 4, 2026 · Version 1.1
You can review and update your cookie preferences at any time. Your choice is saved in your browser.
Cookies are small text files placed on your device when you visit a website. They allow the site to remember your actions and preferences over a period of time, so you don't have to re-enter them each time you visit. Cookies can be "session" cookies (deleted when you close your browser) or "persistent" cookies (stored for a set period).
We also use similar technologies such as localStorage to store your cookie consent preference on your device.
De Energy Hub (deenergyhub.ie) is the data controller responsible for the cookies described in this policy. We are based in Ireland and operate under Irish and EU data protection law, including the GDPR and the ePrivacy Regulations (S.I. No. 336 of 2011).
We group cookies into four categories. Essential cookies are always active. All other categories require your consent before any cookie or script is loaded.
These cookies are strictly necessary for the website to work. They cannot be disabled because without them core features (like page navigation and security) would break. They do not collect personally identifiable information.

De Energy Hub | Stores your cookie consent choice so we do not prompt you on every page visit. | localStorage. We ask again after 12 months, or sooner if this policy changes in a way that affects your choices. Also cleared when you clear browser data. |
We use Google Analytics 4 (GA4) to understand how visitors use our free tools and calculators. This helps us improve the site. Analytics cookies are only loaded after you give consent. IP addresses are anonymised and we do not share this data with third parties for advertising.

If you accept analytics cookies, we measure:
We do not use Google Analytics for advertising, remarketing or audience building, and we have not enabled Google signals.
For full details on how Google processes this data, see Google's Privacy Policy and the Google Analytics data safeguarding page.
Marketing cookies are used to show relevant advertisements and to track the effectiveness of ad campaigns. We do not currently use any marketing cookies. This category is reserved for future use. We will update this policy before activating any marketing cookies and will re-request your consent at that point.
| Name | Provider | Purpose | Expiry |
|---|---|---|---|
| No marketing cookies are currently in use. | |||
Functional cookies allow the website to remember choices you have made (such as calculator preferences or display settings) to provide a more personalised experience on return visits.

| No functional cookies are currently active; this category is reserved for future features. | |||
The easiest way to manage your choices is to use De Energy Hub's own tool:
Open your preferences panel to accept, reject or customise individual cookie categories at any time.
You can also reopen this panel at any time from the Cookie Settings link in the footer of every page. Withdrawing analytics consent stops measurement and removes the Google Analytics cookies we set.
Your preferences are stored in your browser's localStorage under the key deh_cookie_consent. Clearing your browser data will reset your preferences and you will be asked again on your next visit.
You can also control cookies through your browser settings. Note that blocking all cookies may affect how some parts of the website work. Here are links to cookie settings for common browsers:
You can prevent Google Analytics from collecting your data across all websites using the Google Analytics Opt-out Browser Add-on.
Under the ePrivacy Regulations (SI 336/2011) and the GDPR:
Some cookies on this site are set by third-party services (currently Google Analytics only, and only with your consent). We do not control these third-party cookies directly. Please refer to the respective third-party privacy policies for full details:
Our pages currently load fonts from Google Fonts. This sets no cookies, but loading a font means your browser contacts Google's servers, which receive your IP address and browser details. This happens when a page loads, before you make a cookie choice, because it is part of displaying the page. We are working on hosting these fonts ourselves, after which this will no longer apply.
Google LLC is based in the United States. Where Google Analytics data is transferred there, it relies on Google's participation in the EU-US Data Privacy Framework and standard contractual clauses. You can avoid this entirely by declining analytics cookies.
We may update this cookie policy from time to time, for example when we add new features or cookies. We will update the "Last Updated" date at the top of this page and, where changes are material, re-prompt for consent. We recommend checking this page periodically.
Under GDPR you have the right to access, correct, delete or restrict the processing of personal data we hold about you, and the right to withdraw consent at any time. For more detail on your rights and how to exercise them, please see our Privacy Policy. You also have the right to complain to the Data Protection Commission (dataprotection.ie).
