Cookie Policy
1. What are cookies?
Cookies are small text files placed on your device (computer, tablet, or smartphone) when visiting a website. They are commonly used to ensure proper site functioning, remember user preferences, and provide analytics data to operators.
Generally, cookies do not directly identify a person but a browser or device, sometimes with a persistent session. Under the GDPR and UK Data Protection laws, cookies linked to a person are considered personal data and receive the same protections.
2. How Optostak uses cookies
Optostak uses cookies to:
- Ensure the platform functions properly between sessions
- Understand user navigation to improve the site
- Remember optional preferences for a better experience
- Measure the effectiveness of our content and publications
We do not use cookies to collect sensitive data or track users across third-party sites without their consent.
3. Types of cookies we use
3.1 Strictly necessary cookies
Essential for platform operation, they enable navigation, secure access, and session management. They do not require your consent and are used only for these purposes.
Examples: session maintenance, cookie consent memory, proper loading of elements.
3.2 Analytical cookies
They help us understand visitor interaction with Optostak by collecting aggregated and anonymised data on pages visited, duration, paths, traffic, etc. This information is used to improve content and identify technical issues.
These cookies are placed only with your consent, which you can manage via our dedicated tool.
We notably use Google Analytics with IP anonymisation and GDPR-compliant agreements.
3.3 Preference cookies
They remember your choices to personalise your experience (display, language, optional features). They improve usability but are not essential. Their installation requires your consent.
3.4 Marketing and third-party cookies
Currently, Optostak does not run marketing campaigns requiring these cookies. If this changes, we will update this policy and seek your consent.
Embedded third-party content (videos, share buttons) may place their own cookies, independent of our control. Please consult their respective privacy policies.
Examples: embedded videos (functional cookies), share buttons (interaction tracking).
