This notice describes the information used to operate Upgrade Geometry and respond to messages sent to its contact address.
Correspondence
An email gives the mailbox your address and whatever material you include. We use those details to reply, investigate a correction or retain the source context of that conversation.
Requests and visit statistics
Hosting and security services, including Nginx and Cloudflare, process request details such as IP addresses, timestamps and URLs to deliver pages and investigate faults or abuse. Cookie-free Umami statistics summarize visits, referring pages, devices and approximate regions. Visitor registration, comments, newsletters, payments and contact forms are not offered. Reading events, marked affiliate-link clicks and visible product-card impressions can identify the article, destination host and path, short link text and card identifiers. Destination query parameters are excluded from click events. Incoming campaign tags can relate a visit to its referral source. These measurements add no cookies or persistent browser storage, respect Do Not Track and do not report merchant purchases or commissions.
Service providers and records
Website and mail providers process the limited information required to run those services. We do not sell personal information. Logs and correspondence are retained for the operation, security and legal purposes that reasonably require them.
Requests about your information
You can ask about, correct or request deletion of information supplied in correspondence. Security needs and legal record obligations may limit what can be removed.
Privacy contact
Send privacy requests to [email protected] and identify the correspondence concerned.
