Privacy Policy

What we collect. The Site works without an account. Standard web server logs (IP address, user agent, pages requested, timestamps) are kept briefly for security and capacity planning. Preferences you set, including interface language, theme, view mode, and saved instruments, are stored in your own browser (cookies/localStorage), not on our servers.

What we store server-side. If you submit the contact form or sign up for e-mail updates, we store what you send (your message and/or e-mail address) to respond and to send the updates you requested. We do not sell or share this information. You can request deletion at any time via Contact.

Ask the Data. Questions typed into Ask the Data are processed to generate an answer and are subject to a per-connection rate limit; questions are not linked to an identity.

Cookies. First-party cookies/localStorage are used only for the preferences above.

Analytics (Google Analytics 4). This Site uses Google Analytics 4 to understand aggregate readership (pages viewed, approximate region, how readers arrive). Under Consent Mode, all advertising signals are denied by default; analytics storage is used unless you decline it, and no analytics data is tied to your identity by this Site.

Advertising (Google AdSense). If advertising is enabled on this Site, third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies (such as the DoubleClick cookie) enables it and its partners to serve personalized ads. You may opt out of personalized advertising at Google Ads Settings, and learn more at Google's advertising policies. Where required, ad personalization is subject to your consent choices.

Third-party links. News headlines and some resources link to external publishers; their privacy practices are their own.

Changes. This policy may be updated; material changes will be reflected on this page.
