Privacy and analytics

Your message, contact details, and IP address are stored in the site database and are available in the private management area. The message text is also sent to the site owner as a Telegram notification; your contact details are not included in that notification. This information is used to read and reply to your message and is not sent to Google Analytics.

After you consent, the site may send non-personal events from public pages to Google Analytics.

• page views without query parameters or URL fragments;
• clicks on primary calls to action using technical section identifiers;
• tool starts, completions, and mode changes;
• provider and model identifiers for single-model calculations;
• contact form starts, successful submissions, or a normalized error type.

Analytics does not receive form contents, contact details, entered values, request or token counts, calculated costs, search text, full URLs with query parameters, error messages, or secrets. The site does not use fingerprinting or session replay.

Google Analytics loads only after consent. Advertising signals and personalization are disabled. Before consent or after a refusal, analytics requests are not made and earlier actions are not replayed.

Google Analytics may set cookies named _ga and _ga_*. They expire 13 months after the first consent and are not renewed on every visit. Event-level data is retained in Google Analytics for 14 months; this setting does not apply to standard aggregated reports.

You can change your choice through the “About cookies” button at the bottom of the site. When consent is withdrawn, available _ga* cookies are deleted. Analytics is not enabled if the browser sends a Do Not Track signal.

If you have a question about data use, contact me through the existing form or Telegram.
