STORAGE / YOUR BROWSER
Keep the useful notes.
Clear them when you wish.
Cosmoinst uses a small amount of browser storage for specific features. There is no advertising-cookie banner because no advertising or analytics integration is included.
The form session
The cookie cosmic_session links a browser session to a form security token. It is set when the contact endpoint starts a session, uses HttpOnly and SameSite=Lax, and is configured as a session cookie. On an HTTPS host it is marked Secure. Browser settings determine when a session cookie is finally removed.
The launch checklist
The key cosmoinst.launch.v1 stores which preparation items you selected. Changing a checkbox writes that choice on the current device. It has no built-in expiry and is not transmitted to the contact endpoint. Use the checklist reset or the button below to erase it.
Your control
You can also remove this site’s storage in your browser settings. Blocking all cookies can prevent the security-protected contact form from working. Blocking localStorage leaves the checklist usable for the current page, but its state may not survive a reload.
External services
Fonts, interface libraries and images are served locally with the site. No embedded social feeds, remote advertising pixels or third-party analytics calls are part of this build.
