Privacy policy.

What is collected

Aggregate analytics (pages viewed, approximate geography) via a standard analytics setup, and anything you send voluntarily — email, comments, calculator inputs stay in your browser and are never transmitted.

How it is used

To understand which guides help readers, fix broken pages, and respond to messages. Information is never sold, and email addresses are never used for spam or shared with third parties.

How it is protected

Standard security measures protect personal information you enter, submit or access on this site: encrypted (HTTPS) transport, no payment data collected, and no user accounts storing passwords.

Cookies and affiliates

Analytics and affiliate partners (including Amazon.in links) may set cookies to attribute visits and purchases. Blocking cookies in your browser does not break the guides. If you wish to disable cookies entirely, you can do so through your individual browser options — each browser’s help pages describe cookie management.

Advertising cookies

If advertising is enabled, third-party vendors — historically Google AdSense, Commission Junction and Amazon — may use cookies and web beacons to serve and measure ads. Google’s DART cookie, where used, serves ads based on your visit to this and other sites; you can opt out of Google’s ad personalisation via Google’s Ads settings. These ad servers automatically receive your IP address when they serve an ad. This site has no access to or control over third-party advertising cookies; their own privacy policies govern those practices, and this policy does not apply to them.
