Cookie Policy
Last updated:
In case of discrepancy, the Dutch version of this document prevails.
1. What are cookies?
Cookies are small text files that your browser stores on your device when you visit a website. They are used to make the website function correctly, to remember your preferences, and to give us insight into how visitors use the website.
In addition to cookies, we may also use similar technologies such as localStorage, sessionStorage and pixels. In this policy, we refer to all these technologies as "cookies".
2. Strictly necessary cookies
These cookies are essential for the operation of the AquaTrace platform. They cannot be disabled. Without these cookies, the application does not function correctly.
| Name | Purpose | Retention period |
|---|---|---|
| at_session | Keeps you signed in during your visit. Stored securely and not readable by external scripts. | Session |
| at_refresh | Automatically refreshes your sign-in so you do not have to log in repeatedly. Stored securely. | 30 days |
| at_csrf | Protects forms in the application against misuse from external websites. | Session |
| at_lang | Remembers the language you choose on the website, so the application opens in the same language. | 1 year |
3. Analytics cookies (opt-in)
Analytics cookies help us understand how visitors use the marketing website (aqua-trace.be). We only place these cookies after your explicit consent via our cookie banner. The application itself (app.aqua-trace.be) does not use any analytics cookies.
| Name | Provider | Purpose | Retention period |
|---|---|---|---|
| _ga | Google Analytics 4 | Distinguishes unique visitors. Contains an anonymous, random ID. | 2 years |
| _ga_* | Google Analytics 4 | Keeps track of session state for the GA4 measurement instance. | 2 years |
| _gid | Google Analytics 4 | Distinguishes visitors on a daily basis for aggregated statistics. | 24 hours |
IP addresses are anonymized by Google Analytics before processing. Data is processed on Google's servers, partly outside the EEA. This transfer is based on the EU's Standard Contractual Clauses. More information can be found in Google's privacy policy.
4. Marketing cookies
AquaTrace currently does not use any third-party marketing cookies or retargeting pixels. Should this change in the future, this policy will be updated and you will receive a renewed request for consent.
5. How can you manage cookies?
Via our cookie banner
On your first visit to the marketing website, a cookie banner appears that lets you accept or reject analytics cookies. You can change your choice at any time via the cookie link in the website footer.
Via your browser settings
You can manage or delete cookies via your browser settings. Please note that blocking strictly necessary cookies may disrupt the operation of the AquaTrace application.
- Google Chrome — manage cookies

Opt-out for Google Analytics
You can disable tracking by Google Analytics for all websites via the Google Analytics opt-out browser add-on.
6. Changes to this cookie policy
We may amend this cookie policy from time to time. The most recent version is always available at aqua-trace.be/en/cookies.
