Privacy Policy

Algorithm Notes does not require accounts or payments to read educational content. Hosting, analytics, and security providers may process IP addresses, browser or device information, requested pages, timestamps, and referral data to operate and protect the site.

Analytics choices

On algodrills.com, Google Analytics 4 is used only after analytics consent to understand aggregate page visits, content-card clicks, related-note clicks, and site performance. The site does not send user answers, numbers, code, run output, free-form text, email addresses, or names to Google Analytics.

You can accept, reject, or withdraw analytics consent from the cookie notice or the Cookie Settings link in the footer. Accepting analytics grants analytics storage only; advertising storage, ad user data, and ad personalization stay denied unless a separate advertising consent system is configured.

Advertising cookies

Algorithm Notes does not currently load Google AdSense or a Google-certified advertising CMP. If advertising is added later, the privacy notice and consent controls should be updated before ad tags are enabled.
