Cookie Policy
Last updated: May 31, 2026
1. Introduction
This Cookie Policy explains how Know AI, a product of Althera (“we”, “us”), uses cookies and similar technologies (such as browser local storage) when you visit our website. It should be read alongside our Privacy Policy.
Althera is the data controller responsible for the personal data processed through these technologies. You can reach us at the details in section 7.
2. What are cookies?
Cookies are small text files placed on your device when you visit a website. We also use related browser storage mechanisms — such as local storage — which work similarly. In this policy we refer to all of these as “cookies”. They can be set by us (first-party) or by third parties whose services we use.
Today, the technologies we use are first-party local storage only — we do not currently set any third-party, tracking, analytics, or advertising cookies.
3. Categories of cookies we use
Strictly necessary
Needed for the site to function: remembering your appearance preference and your cookie choices. These cannot be switched off.
Legal basis: No consent required — these are essential for the service you requested.
Analytics
Would help us understand how the site is used so we can improve it. We do not currently set analytics cookies — if we introduce them, they will stay off until you opt in.
Legal basis: Your consent (GDPR Art. 6(1)(a)).
Marketing
Would be used to measure campaigns and show relevant messaging. We do not currently set marketing cookies — if we introduce them, they will stay off until you opt in.
Legal basis: Your consent (GDPR Art. 6(1)(a)).
4. Cookies currently in use
| Name | Provider | Type | Purpose | Category | Retention |
|---|---|---|---|---|---|
| theme | Know AI (first-party) | Local storage | Remembers your light/dark appearance preference. | Strictly necessary | Until you clear it |
| knowai-cookie-consent | Know AI (first-party) | Local storage | Stores your cookie choices so we don't ask on every visit and don't load anything you declined. | Strictly necessary | Until you clear it or change your choice |
5. Managing your choices
For any non-essential cookies, we ask for your consent before they are set, and they stay off until you opt in. You can change your choices at any time:
- Use to reopen the consent preferences (also linked in the footer).
- Withdrawing consent is as easy as giving it — choose “Reject all” at any time.
- You can also clear or block cookies and local storage through your browser settings. Note that disabling strictly necessary storage may affect how the site works.
6. Changes to this policy
We may update this Cookie Policy to reflect changes to the technologies we use or for legal reasons. When we make material changes, we will update the “Last updated” date above and, where required, ask for your consent again.
