Cookies and storage
Essential storage first. Analytics by choice.
Last updated 13 August 2026.
Necessary technology
The hosting and Sign in with ChatGPT services may use security and authentication information needed to deliver protected pages. Trajectory also uses browser storage for assessment drafts, analytics consent and short-lived interface state. These functions are necessary to provide a requested feature or remember the user's choice.
Optional analytics
Optional first-party analytics records a random session identifier, event name and page path. It does not start until the user selects Accept analytics. No advertising profile is created and raw IP addresses are not stored in the analytics table.
Payments
If Stripe checkout is activated and a user chooses to open it, Stripe may use its own necessary fraud-prevention and payment technology on its checkout domain. Stripe is not loaded on ordinary Trajectory pages.
Change your choice
Clear the Trajectory site data in your browser to reset the analytics choice. On the next visit, the choice panel will appear again. Browser settings can also remove or block stored data, although doing so may affect sign-in or saved device-local assessment answers.
Current beta position
No advertising cookies, cross-site marketing trackers or third-party analytics scripts are included in this release.
