Privacy Policy

Information processed

Our hosting, security and content-delivery providers may process technical information such as IP address, browser type, device characteristics, requested URL, referrer, timestamps and diagnostic logs. If you contact us, we process the information you choose to provide in order to respond.

Optional Google Analytics

Google Analytics loads only after you choose Allow analytics in the privacy control. Rejection does not restrict access to content or tools. If permitted, analytics may process device and browser information, approximate location, referring pages, page views, engagement, interactions and identifiers to help us understand readership. Calculator amounts are processed locally and are not sent as analytics event parameters. Google signals and advertising-personalization signals are disabled in our configuration.

The Privacy settings button lets you change your choice on any page. Revoking consent removes first-party Google Analytics cookies available to this site and reloads the page to stop the analytics runtime. It does not automatically erase information already received by Google.

AdSense review and advertising status

Advertising runtime scripts are currently disabled. The site retains a public AdSense account-verification meta tag and ads.txt file; these do not themselves load advertising JavaScript. Approval is not guaranteed, and approval does not automatically enable ads in this implementation.

Before enabling advertising, the operator must complete the applicable advertising-consent setup, including a Google-certified CMP where required, and update this policy to reflect the actual configuration. Our optional-analytics control is not a Google-certified advertising CMP. Google explains its processing at How Google uses information from partner sites.

Local storage and cookies

We store your analytics preference and its expiry in your browser's local storage for up to 180 days. If storage is blocked or the preference expires, analytics remains off unless you allow it again. Hosting and security services may use strictly necessary technical mechanisms. You can also delete site data or restrict cookies through your browser settings.

How information is used

• Operate, secure and improve the website.
• Diagnose errors, abuse and performance problems.
• Understand aggregate readership and content usefulness.
• Respond to inquiries and correction requests.
• Meet legal, accounting and fraud-prevention obligations.

Sharing and retention

Information may be processed by service providers that host, secure, analyze or monetize the site, subject to their applicable terms. We do not sell personal information as a standalone product. Technical logs and correspondence are retained only as long as reasonably necessary for the purposes described above or as required by law.

Your choices

Use Privacy settings to reject or revoke optional analytics, or restrict storage through your browser. Depending on your location, you may have rights to request access, correction or deletion of personal information. Contact hello@structurelens.com with a privacy request. Do not send passwords, account keys or unnecessary financial information.

External services and changes

Links and embedded data may lead to third-party services with their own policies. We may update this policy as the site, advertising stack or applicable requirements change. The date above identifies the latest revision.
