Cookie Policy
This policy explains which cookies and similar technologies tetrik.ai uses, what each one is for, and how you can change your mind at any time. It sits alongside our Privacy Policy, which describes how we handle personal data more broadly.
The site is operated by AmPhi Labs B.V., Singel 542, 1017AZ Amsterdam, Netherlands, registered with the Dutch Chamber of Commerce (KvK) under number 42122322, VAT (BTW) number NL869828514B01. We follow the EU ePrivacy Directive (2002/58/EC) as transposed in Dutch law (Telecommunicatiewet art. 11.7a) and the consent standard of the GDPR: nothing optional loads before you say so. No pre-ticked boxes, no cookie wall, no consent-by-scrolling.
1. What a cookie is
A cookie is a small text file a website asks your browser to store on your device. It lets a site recognise a returning browser — to keep a preference, or to count a visit without counting the same person twice. Related technologies such as local storage work the same way in practice, and we treat them under the same rules here.
2. The three categories
Functional — always active
Needed for the site to work and for us to honour your choices. They cannot be switched off, because switching them off would break the thing you asked for. They never track you across other websites, and under Dutch and EU law they do not require your consent.
In our case this category holds exactly one thing: the record of your own cookie choice, so we do not ask again on every page. We store it in your browser's local storage rather than in a cookie, under the keys tetrik-consent-v1 and tetrik-consent-id. It contains your choice per category, the date, the policy version you were shown, and a random identifier that is not linked to your name or email address.
The Tetrik tool itself runs in your browser: the files you upload for a box-size analysis are processed client-side and are not stored in a cookie.
Statistics — optional, off by default
These help us see which pages are useful so we know what to improve. They are only placed if you accept them. If you decline, the Google Analytics script is never loaded at all — your browser makes no request to Google.
| Cookie | Set by | Purpose | Expires |
|---|---|---|---|
_ga | Google Analytics 4 (G-65QGQDH5NZ) | Distinguishes one browser from another so repeat visits are not double-counted | 24 months |
_ga_<container> | Google Analytics 4 | Maintains the session state for a visit | 24 months |
Advertising features, remarketing and data sharing are switched off in our Google Analytics configuration, and IP addresses are truncated before storage. If you later withdraw consent, we delete the _ga cookies already placed.
Marketing — optional, off by default
We currently place no marketing cookies. The category exists so that if we ever add advertising or remarketing technology, it arrives switched off and waits for your permission rather than appearing quietly. If that changes, this page is updated first and anyone who previously chose is asked again.
Decline everything and the site stays fully functional — including the Tetrik tool. There is no cookie wall.
3. Changing your mind
Your choice is not permanent. Open Cookie settings — the link is in the footer of every page — to change any category or withdraw consent entirely. Withdrawing is as easy as giving consent (GDPR art. 7(3)) and takes effect immediately: we stop loading the relevant scripts and delete the cookies already placed.
We ask again after 12 months in any case, and whenever the categories change materially, so consent does not quietly persist for years.
4. Deleting cookies in your browser
You can also clear or block cookies yourself, independently of us. Every major browser offers this under its privacy settings — usually "Clear browsing data" or "Cookies and site data". You can additionally use Google's own opt-out at tools.google.com/dlpage/gaoptout. Blocking all cookies may affect how other websites behave, though it will not break this one.
5. Our record of your choice
The law requires us to be able to demonstrate that consent was freely given, so when you make a choice we keep a record of it: the random identifier generated in your browser, your choice per category, the date, the page you were on, and the version of this policy and banner you were shown. As with any form on this site, our host Netlify also logs the IP address the request came from. We keep these records for as long as the consent is valid and use them for nothing else.
6. Tracking we do not use
- No third-party advertising or retargeting pixels (no Meta Pixel, no LinkedIn Insight, no TikTok pixel).
- No cross-site fingerprinting.
- No session-replay or heatmap tools.
If we add any of these, we will update this policy and re-prompt for consent before activating them.
7. Changes
Material changes are published at tetrik.ai/legal/cookies at least 14 days before they take effect, and the banner re-appears so you can choose again.
