Cookie policy
Last updated: 30 September 2026
1. About this policy
This policy applies to the website quaternion.site, operated by Quaternion. It explains what cookies and similar technologies the site uses and how you can control them.
If you have questions, write to office@quaternion.site.
2. What cookies and similar technologies are
Cookies are small text files that a website stores in your browser. Similar technologies, such as the localStorage feature of your browser, keep small pieces of data on your device in a comparable way.
They are used to make a site work, to remember your choices and, where you allow it, to measure how a site is used.
3. What this site uses
Strictly necessary items do not require consent.
| Name | Provider | Purpose | Type | Duration |
|---|---|---|---|---|
q_consent | quaternion.site | Remembers whether you accepted or declined optional cookies. | Local storage, strictly necessary | 180 days |
__cf_bm | Cloudflare | Security: distinguishes people from automated traffic. Set only when Cloudflare's bot protection is active. | Cookie, strictly necessary | Up to 30 minutes |
4. Analytics and marketing
None are used at present. This site has no advertising cookies, no social media embeds and no third-party fonts. If we add analytics later, they will be listed on this page and will run only after you accept.
5. Your choice
When you first visit, a banner lets you accept or decline optional cookies. You can change your choice at any time with the button below.
You can also clear or block cookies and site data in your browser settings. Declining does not limit what you can do on this site.
6. Changes to this policy
We may update this policy, for example if we add analytics. The date at the top shows when it was last changed. Questions can be sent to office@quaternion.site.
