Privacy Policy
Scope
This notice describes the data used by Panmetry’s calculators, analytics and feedback features.
Calculator and browser settings
Calculations run in your browser. Recipe entries are not included in Panmetry’s own product-event requests. Local storage remembers your unit profile, a language selection, and whether you have used a calculation. The current URL determines the page language. Session storage holds a random session identifier. Calculator drafts remain in page memory.
Technical data and analytics
Panmetry uses Google Analytics 4 and Yandex Metrica with Session Replay (Webvisor), click and scroll analysis. These services process page visits, referral and campaign information, device/browser details, approximate location and interactions. Cookies and similar identifiers help measure visits. Network requests expose an IP address and technical headers to the receiving service and hosting infrastructure. Google states that GA4 does not log or store individual IP addresses.
Session Replay
Webvisor can record interactions such as clicks, scrolling and activity on the page. Feedback and contact fields are marked to exclude their typed contents from Yandex recordings. Avoid entering sensitive data anywhere on the site.
Feedback and service records
Panmetry stores product-event names, mode, language, random session and record identifiers, and timestamps. Calculator feedback stores a rating and any comment. The contact form stores your message, any optional name/email you provide, language, identifiers and submission time so the project can review the request and reply where possible. Contact text and email are not sent as analytics event parameters. Contact messages and calculator feedback are available only to the authorised project owner in a protected administration area. Records include a category, processing status, source page when provided and a test marker. An administrative log records actions without copying message contents. Short-lived request-limit records may use a keyed hash of an IP address; the raw IP is not stored in the application database. Email notifications are not enabled yet.
Browser controls and questions
You can remove cookies and local storage through your browser settings; this resets saved preferences and identifiers. Browser blocking tools may limit analytics. For questions about your message or personal data, use the Contact page.
Advertising
Panmetry currently uses a Google AdSense meta tag to verify the publisher account, but it does not load AdSense advertising scripts or display ads. Before advertising is enabled, this notice will be updated with the relevant providers, advertising cookies, purposes and available choices.
Service policies
