Introduction

1.1. Contento NV (commercial name "Willow"), with registered office at Coupure 88, B-9000 Gent, Belgium and enterprise number 0693.699.260 ("Willow", "we") uses cookies and similar technologies on willow.co and inside the Willow application.

1.2. This Cookie Policy explains what cookies are, which categories we use, what they do, and how you can control them. It supplements our Privacy Policy, where you can read more about how we handle personal data overall.

1.3. By continuing to use the Site you consent to the use of cookies as described below, unless you change your preferences via the cookie banner shown on your first visit, or via the controls in your browser.

02

What are cookies?

2.1. Cookies are small text files that a website places on your device (computer, tablet or phone) when you visit. They are widely used to make websites work, to make them work more efficiently, and to provide information to the owners of the site.

2.2. We also use similar technologies such as local storage, session storage and pixels. Where this Cookie Policy refers to "cookies", it covers all of these technologies unless we say otherwise.

03

Categories of cookies we use

3.1. We group cookies into four categories. The first is always on because the site cannot work without it. The other three are optional and only set if you give consent.

Category A

Strictly necessary

Required for the Site to function. Things like keeping you logged in, remembering your cookie preference, and protecting against fraud.

Always on · no consent required
Category B

Functional

Remember choices you make, such as language, region, or which content you have already seen, so the Site behaves more usefully on return visits.

Opt-in
Category C

Analytics

Help us understand how the Site is used so we can improve it — which pages are popular, where visitors come from, where things break. This category also covers session recording: Hotjar captures mouse movement, clicks and scrolling on the pages you visit, and turns them into heatmaps and replays we watch back.

Opt-in
Category D

Marketing

Used by us and our partners to measure the effectiveness of our advertising and to show you Willow ads on other sites you visit — including inside ChatGPT, where OpenAI matches a visit here against an ad you were shown there. It also covers Leadfeeder, which identifies the company you are visiting from by looking your IP address up against a business database, so our sales team can see which firms have read which pages.

Cookies we use on willow.co

4.1. The table below lists the cookies set when you visit the Site, grouped by category. We review this list whenever we make material changes to the Site.

4.2. Not every entry below is strictly a cookie. Some are stored in your browser's local or session storage instead, which does the same job by other means; the "set by" column says which. And some carry a third party's name but are stored on willow.co rather than on theirs — a first-party cookie written by their script. We list them all the same way, because what matters is what is stored and who reads it, not the mechanism.

A · Strictly necessary
NameSet byPurposeDuration
willow:consentwillow.co (local storage)Stores your cookie choice, the time you made it and the policy version it applied to, so we don't ask again and can show what was agreed.1 year
cookieyes-consentwillow.coCookieYes — the consent banner's own record of which categories you accepted or refused. Set whichever way you answer, including when you refuse everything, because refusing is itself a choice we have to remember.1 year
B · Functional
NameSet byPurposeDuration
willow-langwillow.co (local storage)Remembers whether you last read the English or Dutch version of the Site.Until you clear it
C · Analytics

Set only if you accept analytics cookies.

NameSet byPurposeDuration
_gawillow.co (written by Google Analytics)Google Analytics — distinguishes unique visitors.2 years
_ga_*willow.co (written by Google Analytics)Google Analytics 4 — session and engagement state.2 years
_hjSessionUser_*willow.co (written by Hotjar's script)Hotjar — recognises you across visits so repeat sessions are attributed to one visitor.1 year
_hjSession_*willow.co (written by Hotjar's script)Hotjar — holds the current session. Hotjar records how pages are used, which includes mouse movement, clicks and scrolling, and builds heatmaps and session replays from it. It is not only page counts, which is why we name it here rather than leaving it under "analytics".1 hour
_hjTLDTestwillow.co (written by Hotjar's script)Hotjar — works out which domain to store its cookies on. Deleted again immediately.Session
D · Marketing

Set only if you accept marketing cookies. Which of these appear depends on which tags are active in our tag manager at the time.

NameSet byPurposeDuration
hubspotutkhubspot.comHubSpot — identifies your browser so a demo booking can be linked to how you found us.6 months
__hstc, __hssc, __hssrchubspot.comHubSpot analytics — visit and session state.Session to 6 months
_fbpwillow.co (written by the Meta Pixel)Meta Pixel — measures the performance of our ads.90 days
_gcl_auwillow.co (written by Google Ads)Google Ads — links ad clicks to actions on the Site.90 days
IDEdoubleclick.netGoogle DoubleClick — records that you were shown or clicked one of our ads and what you did here afterwards, so we can tell which ads lead anywhere. Unlike the row above this one is set on Google's own domain, which means it can be read on any other site carrying the same tag.13 months in the EEA and UK
test_cookiedoubleclick.netGoogle DoubleClick — checks whether your browser will accept a cookie at all. Holds nothing about you and is replaced constantly.15 minutes
bcookie, li_sugr, UserMatchHistorylinkedin.comLinkedIn Insight Tag — ad measurement and audience matching.Up to 1 year
lidc, li_gclinkedin.comLinkedIn — not ad measurement, despite sitting in this category: lidc picks which of LinkedIn's data centres answers the request, and li_gc holds a non-member's own cookie choice on LinkedIn's side. LinkedIn files both as preferences. They are listed here because on this Site nothing reaches LinkedIn unless you accept marketing cookies or click to load an embed, so that is the only way they can appear.24 hours and 6 months
_lfawillow.co (written by Leadfeeder's script)Leadfeeder — looks your IP address up against a business database to work out which company you visit from, so our sales team can see which firms have read which pages. The result is company-level, not a name, but the lookup runs on your IP and it follows you across visits.1 year
__obrefwillow.co (written by OpenAI's script)ChatGPT ads — a random identifier for your browser. Lets OpenAI join a visit here to an ad you were shown in ChatGPT, so we can see which of those ads lead anywhere. It is stored on willow.co, but it is read by OpenAI.1 year
__opprefwillow.co (written by OpenAI's script)ChatGPT ads — the click identifier from the ad you arrived on, taken from the oppref parameter in the link. Only set if you came from a ChatGPT ad.30 days
__oaiq_consent, oaiq_consent, oaiq_cs:*willow.co (cookie, local storage and session storage)ChatGPT ads — OpenAI's own record of the answer we passed on to it, so its script does not have to re-derive it on every page. Our copy of your choice is the willow:consent entry in section A; this is theirs.30 days, session, and until you clear it
__oaiq_domain_probewillow.co (written by OpenAI's script)ChatGPT ads — works out which domain to store the above on. Deleted again immediately.60 seconds
__cf_bm, _cfuvidbzrcdn.openai.comCloudflare, on the server OpenAI serves its script from — tells automated traffic from real visitors. Set only as a side effect of loading that script, so only if you accept marketing cookies. CookieYes files these as strictly necessary by default; on this Site they are not, because nothing here needs them.30 minutes and 1 year
E · Embedded content

Third-party cookies

5.1. Most of the cookies above are written by a third party's script — analytics providers, advertising platforms and embedded content (e.g. LinkedIn, Meta, YouTube). Being stored on willow.co rather than on their own domain makes no difference to what they are for: the party named in the "set by" column is the one that reads them, and their own privacy policy governs what they then do with the data. A first-party cookie is not a private one.

5.2. Useful third-party privacy policies:

  • Google — policies.google.com/privacy
  • Meta (Facebook & Instagram) — facebook.com/policy.php
  • LinkedIn — linkedin.com/legal/privacy-policy
  • OpenAI (ChatGPT ads) — openai.com/policies/privacy-policy
  • HubSpot — legal.hubspot.com/privacy-policy
  • Hotjar — hotjar.com/legal/policies/privacy
  • Leadfeeder (Dealfront) — dealfront.com/privacy
  • CookieYes — cookieyes.com/privacy-policy
  • Netlify (hosting) — netlify.com/privacy

Changes to this policy
