Cookie Management Policy
Last updated: October 28, 2026
This policy explains which cookies and similar technologies sengo.com uses, what they are for and how you can control them. It complements our Privacy Policy.
What is a cookie?
A cookie is a small text file a website stores on your device. Similar technologies, such as the browser's local storage, play a comparable role. In this policy, "cookies" means all of these technologies.
Our approach
- Non-essential cookies, such as Google Analytics and HubSpot cookies, are off by default. They are only activated with your consent, which you give or refuse in the banner shown on your first visit.
- Until you accept, Google Analytics and HubSpot do not store any cookie on your device.
- Until you accept, our website platform measures traffic without a visitor identifier and does not identify the company a visit comes from.
- We do not use advertising cookies and do not show ads on our site.
- YouTube videos only load when you click to play them.
Cookies we use
Site operation and basic audience measurement
Our website platform, Ploy, stores technical identifiers used to run the site, secure it and measure traffic in aggregate (page views, traffic sources, clicks and forms). Without your consent, this measurement uses an anonymous identifier that resets every day and is not stored on your device.

|---|---|---|---|
| ploy_consent | Ploy (Sengo) | Remembers that measurement with a visitor identifier is off | 180 days |
| ploy_session | Ploy (Sengo) | Groups the pages viewed during one visit | 30 minutes of inactivity |
| ploy_pending_events | Ploy (Sengo) | Temporarily holds measurements not yet sent | Until they are sent |
| sengo-consent | Sengo | Remembers your cookie choice | 6 months |
Additional audience measurement (with your consent)
| Name | Provider | Purpose | Duration |

| ploy_anon_id | Ploy (Sengo) | Random identifier that recognizes returning visitors and lets us identify the company a visit comes from | 1 year |
| _ga | Google Analytics | Tells visitors apart | 2 years |
| _ga_<ID> | Google Analytics | Keeps session state | 2 years |
| __hstc | HubSpot | Tells visitors apart and records the time of each visit | 6 months |
| hubspotutk | HubSpot | Links your visits to your contact record when you send us a form | 6 months |
| __hssc | HubSpot | Counts the pages viewed during one visit | 30 minutes |

How to control cookies
- Your consent: you can refuse non-essential cookies or withdraw your consent at any time with the link at the bottom of every page. We keep your choice for 6 months, then ask again.
- Your browser: most browsers let you block or clear cookies and local storage. The site still works if you do.
