Cookies
A short, complete list of what we store on your device.
No advertising cookies, no third-party trackers — and analytics only if you say yes.
Last updated 13 August 2026. Governed by Swedish law.
1.We use no advertising or tracking cookies
There is no Google Analytics, no Meta pixel, no ad network and no cross-site tracking on this site. Nothing that is not strictly necessary is stored or sent before you make a choice in the consent banner.
2.Everything stored in your browser
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
| oresund_analytics_consent | Local storage — strictly necessary | Remembers whether you accepted or declined anonymous analytics. | Until you reset your choice or clear your browser. |
| oresund_session | Local storage — analytics (only after consent) | A random session id with no link to your identity, so repeated events from one visit can be counted once. | Until you clear your browser or decline analytics. |
| oresund_input / saved answers | Local storage — strictly necessary | Your calculator answers, so you can leave and come back. Never sent to our servers. | Until you press “Start over” or clear your browser. |
| sb-*-auth-token | Local storage — strictly necessary | Keeps you signed in after you use an email sign-in link. | Until you sign out or the session expires. |
3.Consent under the Swedish Electronic Communications Act
Storing or reading anything on your device that is not strictly necessary requires your consent (lagen om elektronisk kommunikation, implementing the ePrivacy Directive). Analytics here is opt-in: until you press “Accept analytics”, no event is recorded. Declining is one click and costs you no functionality.
4.Changing your mind
Use the switch below, or the same control on the privacy page. Turning analytics off stops collection immediately.
Analytics preference
When enabled, we store anonymous usage events and the numbers your calculation produced, linked only to a random session id. Turning this off stops all collection immediately — the calculator keeps working exactly the same.
