1. What Are Cookies?
Cookies are small text files that a website stores on your device (computer, tablet or phone) when you visit. They serve various purposes, such as remembering your preferences or keeping you logged in. Some cookies are placed by us (first-party cookies); others may be placed by third-party services we use.
2. How We Use Cookies
Minimal cookie usage: Custos AI uses a minimal number of cookies. We do not use advertising cookies, tracking cookies, or social media cookies. We do not use Google Analytics, Facebook Pixel, or any comparable third-party tracking service.
The cookies we use fall into two categories: strictly necessary cookies and analytics (cookie-free).
3. Strictly Necessary Cookies
These cookies are essential for the Websites to function. They do not require your consent under the Dutch Telecommunications Act (Article 11.7a) and the GDPR, because the Websites cannot operate properly without them.
Authentication cookies (app.custosai.eu)
| Cookie | Purpose | Type | Duration |
|---|---|---|---|
| access_token | Authenticates your session after login (JWT) | First-party, session | Until browser is closed or session timeout |
| refresh_token | Allows secure renewal of your session without re-entering credentials | First-party, persistent | 7 days |
These cookies are set only after you log in to the chat application. They are not set for visitors who do not have an account.
Cookie consent (custosai.eu)
| Cookie | Purpose | Type | Duration |
|---|---|---|---|
| cookie_consent | Stores your cookie consent preference so the banner is not shown again | First-party, persistent | 12 months |
Language preference (custosai.eu)
| Cookie | Purpose | Type | Duration |
|---|---|---|---|
| NEXT_LOCALE | Stores your preferred language (NL, EN, DE) so pages load in the correct language | First-party, persistent | 12 months |
This cookie is exempt from consent requirements under Article 5(3) of the ePrivacy Directive (functional cookie exemption), as it is strictly necessary for delivering the service in the requested language.
4. Analytics — No Cookies
Vercel Analytics (custosai.eu): Our marketing website uses Vercel Analytics, a privacy-friendly analytics service. Vercel Analytics works without cookies, does not collect personal data, does not track individual visitors across sessions, and does not share data with third parties. Because Vercel Analytics does not place cookies and does not process personal data, it does not require your consent under the GDPR or the Dutch Telecommunications Act.
Vercel Analytics collects only aggregated, non-identifiable data such as page views, referrer information and country-level location (derived from anonymised IP addresses that are not stored). More information: vercel.com/docs/analytics/privacy-policy.
Plausible Analytics (custosai.eu): We also use Plausible Analytics to measure aggregate website traffic. Plausible is privacy-friendly and does not use cookies, does not collect personal data, and does not track you across websites. The service runs on EU infrastructure (Germany). No consent banner is required because no personal data is processed.
5. Third-Party Cookies
Custos AI does not place or allow any third-party cookies on its Websites. Specifically, we do not use:
- Advertising or remarketing cookies
- Social media tracking cookies or pixels
- Third-party analytics that rely on cookies
- Cross-site tracking technologies of any kind
6. Cookie Banner
When you first visit custosai.eu, a cookie banner is displayed. Because we only use strictly necessary cookies (which are exempt from consent requirements) and cookie-free analytics, the banner serves an informational purpose: it informs you about our use of cookies and links to this policy.
You are not required to give consent for our current cookie usage. If we introduce optional cookies in the future (such as preference or marketing cookies), we will update this policy and request your explicit, informed, freely given consent before placing them — in accordance with the ACM guidelines and the GDPR.
7. Managing Cookies
You can manage or delete cookies through your browser settings at any time. Please note that disabling strictly necessary cookies may prevent you from using the chat application (app.custosai.eu), as authentication cookies are required to maintain your login session.

8. Changes to This Policy
We may update this Cookie Policy from time to time. Material changes will be communicated via the cookie banner or by notice on the Websites. If we introduce new categories of cookies that require consent, we will request your consent before placing them.
