Cookies and local storage
Last updated: 1 August 2026
This is the complete list. Every item below is either strictly necessary to run the service or a preference you set yourself. None are used for analytics, advertising or tracking across sites, so no consent banner is required — and there isn't one.
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
| oddrail_session | Cookie (HttpOnly, SameSite=Lax) | Keeps you signed in. Holds a signed reference to your account and nothing else. | 7 days |
| age_ok | Cookie | Remembers that you confirmed you are 18 or older, so the check is not repeated. | 30 days |
| theme | Local storage | Remembers whether you chose the light or dark appearance. | Until you clear it |
| session_limit_min | Local storage | The session reminder you set in Settings. | Until you clear it |
| session_started_at | Local storage | When the current visit began, so the reminder fires once rather than repeatedly. | Until you clear it |
Turning them off
Local storage items can be cleared in your browser at any time, and the session reminder has its own off switch. Blocking the session cookie signs you out and keeps you signed out; the rest of the site still works.
