Essential storage
Nerovia saves your cookie choice and your Windows guidance or Dehumidifier Finder answers in your browser. This supports preference memory, back navigation and refresh or resume behaviour. Saved tool answers expire 30 days after their last update. A server-readable proof of your cookie choice lasts up to 180 days so the service can enforce it consistently.
Optional analytics
Analytics events and first/latest-touch attribution storage are suppressed unless you actively allow anonymous analytics. When allowed, a random journey identifier and first-party attribution record can remain for up to 30 days. Rejecting is as easy as accepting and removes those optional cookies. No third-party analytics, marketing or advertising technology is currently configured.

Changing your choice
Use the controls below at any time. Clearing Nerovia site data in your browser also removes the saved preference and locally stored tool answers.
Future changes
Before any new non-essential supplier or advertising technology is introduced, this notice and the consent choices must be updated and reviewed. Allowing analytics here does not permit marketing or personal-data sharing with lead buyers or providers.
Material changes create a new notice version and cause Nerovia to ask for a fresh choice where required.
