LEDGER / COOKIES13 ROWS

Two keys run by default. Every ad cookie waits for your Allow.

This site sells 3D CAD software and buys search ads to find engineers who want it. Below is each cookie and storage key it can set, written as a ledger: what the row is, what it means in plain words, and why it applies. Prose is kept for what a table cannot hold.

Effective date

Clause C-00

This cookie notice takes effect on October 6, 2026. It sits beside the privacy policy, which covers the inquiry form, the chat and the logs. This page covers only what lands in your browser.

C-01Strictly necessary Remembers your cookie choice and holds the token that reconnects you to an open support chat. Without them the banner reappears on every page and a chat thread is lost on reload. They run without consent and carry no advertising data.
C-02Analytics Counts visits and which pages were read, for example how many people opened the assembly benchmark. Tells us which documentation is used. Set only after Allow, controlled by analytics_storage.
C-03Advertising Links an ad click to a later enquiry so the platform can report which campaign worked. We pay for clicks on Google, Microsoft and Meta. Set only after Allow, controlled by ad_storage.

Google Ads, Microsoft Advertising and Meta Ads send traffic to this site today. Someone searching "solidworks alternative" or "inventor alternative" clicks an ad, and the platform appends its identifier to the link. Decline, and the identifier sits in the address bar for that page view and goes nowhere.
