Privacy & cookies · updated 2026-08-20

A short record of what this site stores.

You can use every guide without an account and without accepting analytics or advertising.

Before you choose

Microsoft Clarity loads with analytics and advertising storage denied. In this limited no-cookie mode Microsoft may receive basic page-view and interaction signals, but it cannot use analytics cookies or maintain the fuller continuous session available after consent. A necessary local-storage entry records whether you accepted or rejected analytics so the choice is not asked on every visit.

Adsterra advertising

Adsterra display banners load only after you choose “Allow analytics & ads.” We use responsive 728×90 or 320×50 banner units and do not enable Popunder, Social Bar, Smartlink, or adult ads. Adsterra and its advertising partners may process IP address, device and browser information, ad interactions, cookies, and similar identifiers to select, deliver, measure, and protect advertising.

Choosing “Analytics only” or “Reject optional” prevents this site from requesting Adsterra code. You can withdraw permission from the footer; the current ad is removed, although third parties may retain data already processed. Read Adsterra's Privacy Policy ↗ and Cookie Policy ↗.

If you accept analytics

Microsoft Clarity project y49uhw12rc loads to measure anonymous page use, navigation, scrolling, device information, and interaction patterns. Analytics storage is granted; advertising storage remains denied. Microsoft may set analytics cookies and process usage data under its own privacy terms.

Microsoft Privacy Statement ↗

Change or withdraw your choice

Use “Privacy & cookies” in the footer. Rejecting after acceptance sends a denied consent signal and clears Clarity cookies through its consent API. The tag remains in limited no-cookie mode on later visits so the site can receive basic, fragmented diagnostics without analytics storage.
