Cookies and storage
What onassian.com stores in your browser. The short answer is nothing, and this page explains how we checked.
onassian.com sets no cookies and writes nothing to your browser’s local storage, session storage or IndexedDB. So there is no cookie banner: we would only need one to ask your consent for cookies that aren’t essential, and we use none.
What we set
| Name | Set by | Purpose | Lasts |
|---|---|---|---|
| None | onassian.com | We set no cookies and store nothing in your browser. | Not applicable |
How we checked
On 29 September 2026 we checked the live site. Its responses, including the home page, the edition data and the contact endpoint, carried no Set-Cookie header. The site’s script makes no use of cookies, local storage, session storage or IndexedDB. Light and dark mode follow your device’s setting through your browser, so no theme preference is saved. We check again whenever the site changes.
What could appear, and why
- Cloudflare security cookies
- Cloudflare, our host, can set a strictly necessary cookie such as
__cf_bmorcf_clearanceif its bot protection needs to check a browser. They exist to keep the site safe, don’t track you across sites and expire within hours. Because they are strictly necessary, they don’t need consent. We haven’t seen them on onassian.com. - TradingView charts on the Stock Deck
- The charts are drawn by TradingView in a frame loaded from tradingview.com. What that frame stores is set by TradingView, under its own policy. That is why each chart loads only after you choose to show it: until you press “Show chart”, nothing is requested from TradingView.
- Fonts
- Our typefaces are served from our own site, so no font service is involved and nothing is stored.
If this changes
If we ever add a cookie or browser storage that isn’t strictly necessary, for example analytics or a saved preference, we will list it here with its name, purpose and lifetime first, and ask before setting it where the law requires consent.
Managing cookies
