Last updated: 19 August 2026. Most cookie policies list a dozen trackers. This one is short, because Longevity Lab sets none.
Cookies we set
None. Browsing longevity-lab.fit places no cookie on your device. That is why you see no cookie banner: there is nothing to consent to. We verify it as part of our release checks — the site is not allowed to ship a Set-Cookie header on a public page.
Third-party cookies
None. We load no analytics, no advertising network, no social widgets, no embedded video players, no comment system and no font service that could set one. Every script, stylesheet, font and image on this site is served from our own domain.
What is stored on your device
One thing, and only if your browser supports it. Longevity Lab is a progressive web app, and a service worker keeps copies of pages, stylesheets, fonts and images in the browser’s own Cache Storage so that pages open quickly and the site still works when you lose your connection.
That cache holds no identifier, no cookie and nothing about you. It never leaves your device and we cannot read it. Under the EU ePrivacy Directive and the UK PECR it is strictly necessary storage — it exists solely to deliver the service you asked for — which is the category that does not require consent.
How to remove it
Clearing site data for longevity-lab.fit in your browser settings removes the cache immediately. You can also block service workers entirely in your browser’s privacy settings, or browse in a private window, where nothing persists after you close it. The site works normally either way; it simply loads from the network every time and does not open offline.
Server logs are not cookies
Our web server keeps a short-lived technical log of the requests it serves, as every web server does. That is not storage on your device and is not covered by cookie law, but you should know it happens: what it records and how long we keep it is set out in our Privacy Policy.
If this changes
If we ever add analytics, a newsletter or any other technology that stores or reads information on your device, we will update this page before it goes live, and we will ask for your consent first wherever the law requires it.
