Cookies and browser storage
What the analyzatorvibraci.cz website stores in your browser and how to change your video consent. Effective 11 October 2026.
In short
The website uses no advertising, analytics or tracking cookies. It stores in your browser only what is needed for features you use yourself. The law does not require consent for that, so we do not show a cookie banner. The only exception is YouTube videos: they load only with your consent.
1. What the website stores in your browser
The website itself uses no HTTP cookies. For these features it uses browser storage (localStorage, sessionStorage). The data stays on your device and is never sent anywhere.
| Name | Purpose | Type and duration |
|---|---|---|
vibe_theme | Light / dark mode you chose with the button in the header. | localStorage, until you delete it |
vibe_enquiry_draft | Copy of an unsent enquiry so it is not lost if sending fails. | sessionStorage, cleared after sending or when the tab closes |
vibe_demo_* | Settings of the online app demo (machine, mode, view). | sessionStorage, cleared when the tab closes |
vibe_consent_youtube | Your choice "Always load videos". | localStorage, until you withdraw consent |
2. YouTube videos – only with your consent
The videos on the Videos page are hosted on YouTube. Until you click play, the website does not connect to YouTube at all. After you click, the video loads from youtube-nocookie.com (privacy-enhanced mode). YouTube (Google) then receives your IP address and browser details and may store cookies and similar data in your browser, under the Google Privacy Policy.
Consent for all videos: can only be changed with JavaScript enabled
After you withdraw consent, videos no longer load automatically. Data YouTube has already stored in your browser can be deleted in your browser settings (clear cookies and site data).
3. Contact form
The form stores no cookies. When you send it, the Web3Forms service delivers it to our email. See the privacy policy.
4. How to delete or block stored data
Delete stored data in your browser settings (Chrome, Edge, Safari, Firefox: Settings › Privacy › Clear browsing data / cookies and site data). The website works without it; it just will not remember your chosen theme.
5. Legal basis
Storage that is strictly necessary for a feature you request needs no consent (Art. 5(3) of Directive 2002/58/EC, implemented in the Czech Republic by Section 89(3) of Act No. 127/2005 Coll.). YouTube videos load only with your consent (Art. 6(1)(a) GDPR). Who the controller is and what rights you have is in the privacy policy and its GDPR section.
