1. First-party records
rail-theme stores your light/dark choice; rail-demo-notes, rail-demo-tasks, rail-demo-folders and rail-demo-settings store only your public-demo content and demo behaviour preferences.
These records are not used for advertising profiles. They can be deleted with the demo reset command or by clearing browser site data.
2. Paddle checkout
When you press a purchase button, Paddle checkout opens as a separate payment surface. Paddle may use its own necessary cookies/similar technologies for payment security, fraud prevention, tax and checkout functions; these are governed by Paddle's policies.
