Cookie policy
The cookies this site sets, what they are for, how long they last, and how you change your choice.
Last updated: 16 October 2026.
What cookies are
Cookies are small text files that a website stores on your device. They can be "strictly necessary" (needed to deliver the site securely) or optional (used for analytics, personalisation, or advertising). Under EU rules, optional cookies may only be set with your consent.
Your choice
On your first visit, a cookie banner asks for your choice. Accept all, Reject all and Choose cookies are on the first screen, and rejecting is one click, the same as accepting. Until you choose, only strictly necessary cookies are used. Google Analytics runs in Consent Mode with all storage denied, so it sets no cookies and stores no identifier.
You can change or withdraw your choice at any time from Cookie settings at the bottom of every page, or with the button below. When you withdraw consent for statistics, the analytics cookies on this site are deleted and no further data is sent.
We ask again when the list below changes, and at the latest after 12 months.
Strictly necessary cookies
These cookies are needed to deliver the site securely and to hold your cookie choice. They do not need consent and they are always on.
| Cookie | Set by | Purpose | When it is set | Data shared with | Lifetime |
|---|---|---|---|---|---|
ack_consent | argnode.com | Holds your cookie choices, so we do not ask again on every page. | When you make a cookie choice. | 12 months | |
ack_form_key | argnode.com | A random key that ties together the messages you send through our contact form from this browser, so we can see they belong together and stop misuse. It does not identify you and is never used for analytics or advertising. | When you send a message through the contact form. | 3 months | |
__cf_bm | Cloudflare (our content delivery network) | Holds a bot score. It is used to tell people and bots apart, to protect the site from abuse. | Only when Cloudflare's bot protection checks a request. | Cloudflare processes it on our behalf to deliver the site securely. | 30 minutes |
cf_clearance | Cloudflare (our content delivery network) | Holds proof that your browser passed a security check, so you are not asked again. | Only after a Cloudflare security check. | Cloudflare processes it on our behalf to deliver the site securely. | 30 minutes |
Statistics cookies
These cookies are set only if you allow statistics. We use them to count visits and to see which pages people read.
| Cookie | Set by | Purpose | When it is set | Data shared with | Lifetime |
|---|---|---|---|---|---|
_ga | Google Analytics. Holds a random browser ID. It is used to tell visits from different browsers apart, so visitors can be counted. | When you allow statistics. | Google receives a browser ID and the pages you visit. | 2 years | |
_ga_* | Google Analytics. Holds information about your current visit, so it is counted as one visit. | When you allow statistics. | Google receives a browser ID and the pages you visit. | 2 years | |
ack_uid | argnode.com | Holds your pseudonymous customer ID. It is used to link your visits and sessions together in Google Analytics, also across devices. It contains no name or email address. | Only if you came from our customer portal or a personal link from us, and you allow statistics or marketing. | Google receives the ID with your visit data. Your banner choices are saved to your customer record in our CRM. | 12 months |
Google Analytics is loaded through Google Tag Manager. Google may process this data outside the EEA; the privacy policy describes the safeguards.
Marketing cookies
These cookies are set only if you allow marketing. We use them to see which of our ads bring visitors and to show relevant ads. Allowing marketing also lets Google use your visit for advertising (Google Consent Mode: ad storage, ad user data and ad personalisation).
| Cookie | Set by | Purpose | When it is set | Data shared with | Lifetime |
|---|---|---|---|---|---|
ack_uid | argnode.com | Holds your pseudonymous customer ID. It is used to link your visits and sessions together in Google Analytics, also across devices. It contains no name or email address. | Only if you came from our customer portal or a personal link from us, and you allow statistics or marketing. | Google receives the ID with your visit data. Your banner choices are saved to your customer record in our CRM. | 12 months |
Customer ID
This applies only if you came from our customer portal or a personal link from us. We then know you are our customer, and we use your pseudonymous customer ID: a random code that contains no name or email address. If you allow statistics or marketing, the ID is stored in the ack_uid cookie and Google Analytics uses it to link your visits and sessions together, also across devices.
If you have already made your choices in our customer portal, the banner uses them and does not ask again. Banner choices you make on such a visit are saved to your customer record in our CRM, so we can respect them on your other devices. Allowing statistics allows all analytics uses in your record, and allowing marketing allows all digital marketing uses except email. For more detailed choices, sign in to the customer portal or contact us.
From the contact form. When you send our contact form, the strictly necessary ack_form_key cookie stores a random key (listed above). If you allow statistics or marketing, and we have accepted your contact, the site exchanges the key once for your customer ID, stores the ID in ack_uid as described above, and deletes the key. Without that consent, the key is never exchanged and never used for analytics.
Preferences and other cookies
This site sets no preference cookies.
Managing cookies in your browser
You can also block or delete cookies in your browser settings. Blocking strictly necessary cookies may affect how the site works, and the cookie banner will ask again if your choice is deleted.
Cookies in our services
This policy covers this marketing website. Client-facing tools and portals we operate may use their own session and authentication cookies, which are described where those tools are provided.
