Cookie Policy
Last updated: 15 September 2026
This Cookie Policy explains how DIY Solar ("we", "us", "our") uses cookies and similar technologies on diysolar.io, and how you can control them. It should be read together with our Privacy Policy, which describes how we handle personal information more broadly.
1. What are cookies?
Cookies are small text files that a website stores on your device. They allow the site to remember your actions and preferences (such as staying signed in) over time. We also use the term to cover similar technologies such as local storage.
2. Your consent
When you first visit DIY Solar, a banner asks you to accept all cookies or continue with essential
cookies only. Your choice is remembered in the diysolar_consent cookie. You can change
your mind at any time using the Cookie settings link in the footer, or by clearing
cookies in your browser.
We do not use advertising, profiling or third-party analytics cookies. Because we only use cookies that are necessary to run and secure the site (plus security-related cookies described below), refusing them would prevent core features such as signing in from working.

4. Managing and deleting cookies
You can control cookies in several ways:
- On DIY Solar: use the Cookie settings link to clear your saved choice and show the banner again.
- In your browser: most browsers let you view, block and delete cookies in their settings (usually under "Privacy" or "Security"). Blocking all cookies may prevent you from signing in or using account features.
- Google: manage Google's cookies through your Google account and the link above.
Deleting cookies removes your saved preferences and signs you out of your account.
5. Changes to this policy
We may update this Cookie Policy when our use of cookies changes. The "Last updated" date at the top of this page will always reflect the current version.
