1. Our Own Cookies: None
The calculators on this site run entirely in your browser and need no cookies, no local storage and no session to work. We have no login, no preferences to remember and no first-party tracking. If you block every cookie, every tool on this site still works.
2. Third-Party Cookies We Allow
Two Google services place cookies when you visit:
Google Analytics (GA4)
| Cookie | Purpose | Typical Duration |
|---|---|---|
| _ga | Distinguishes visitors with a random ID so page views can be counted without identifying you | 2 years |
| _ga_<id> | Keeps session state for our specific Analytics property | 2 years |
Google AdSense and Advertising Partners
| Cookie | Purpose | Typical Duration |
|---|---|---|
| __gads / __gpi | Ad delivery and measurement; frequency capping (set under this site's domain by Google) | 13 months |
| __eoi | Ad measurement where personalised advertising is limited | 6 months |
| IDE | Ad personalisation and measurement (set by doubleclick.net) | 13 months |
| test_cookie | Checks whether your browser accepts cookies | 15 minutes |
The exact set can vary as Google updates its services and depending on your region and ad settings. Google's own reference of cookie types used in advertising and analytics is at policies.google.com/technologies/cookies.
3. Consent
This site is built for visitors in India and does not show a cookie consent message. The cookies described above are used as standard; you can opt out at any time using the controls below, and blocking them never stops the calculators from working.
4. How to Control Cookies
- Browser settings: every major browser lets you block or delete cookies per site or globally (look for "Cookies and site data" in settings). Blocking cookies does not break our calculators.
- Personalised ads: switch off at adssettings.google.com or via aboutads.info/choices.
- Analytics: install the GA opt-out add-on.
5. Changes and Contact
If the services we use change, this list will be updated along with the date at the top. Questions: contact@solarcalculatorspro.online. See also our privacy policy and disclaimer.
