Cookie Policy

Cookies are small text files that a website places on your device (computer, tablet, or smartphone) when you visit it. They are widely used to make websites work, to remember your preferences, and to provide information to the site operator.

Cookies can be “session cookies” (which are deleted when you close your browser) or “persistent cookies” (which remain on your device for a set period or until you delete them manually).

The following table lists every cookie used on the Cluster subdomains. Both are classified as strictly necessary — the platform cannot function properly without them.

The central domain logbookos.com serves as the brand hub, legal framework, and public-facing information site. It does not require authentication and does not set the session or trusted_device cookies described above.

4.1 Current status. As of the effective date of this policy, no non-essential cookies are active on logbookos.com. The cookie consent banner is present on the site but no analytics, marketing, or preference cookies are currently deployed.

4.2 Planned cookies. We intend to introduce analytics and/or marketing cookies on logbookos.com in the future to understand how visitors interact with our public pages and to measure the effectiveness of our outreach. When we do, the following categories may be activated:

4.3 Consent required. None of these cookies will be set without your prior, explicit consent. When they are activated, you will be able to manage your preferences through the cookie consent banner on logbookos.com. You may accept all, accept only necessary cookies, or customise your selection at any time.

4.4 Scope limitation. Even after activation, these cookies will apply only to logbookos.com. They will never be deployed on any Cluster subdomain. Your workspace remains cookie-free except for the two strictly necessary cookies described in Section 3.

For complete transparency, the following categories of cookies are not used anywhere on the Cluster subdomains and are not currently active on logbookos.com either:

• Third-party tracking cookies — We do not use Google Analytics, Meta Pixel, Hotjar, Mixpanel, or any third-party tracking service on the Clusters. If analytics are introduced on logbookos.com, they will be disclosed in Section 4 and require your consent.
• Advertising / Remarketing cookies — We do not run remarketing campaigns or set advertising pixels on any Cluster subdomain.
• Social media cookies — We do not embed social media widgets that set their own cookies.
• Cross-domain tracking — Cookies set on one domain or subdomain cannot be read by another. We do not use any mechanism to track you across domains.

6.1 Strictly necessary cookies (Clusters). Under the EU ePrivacy Directive (2002/58/EC, as amended by 2009/136/EC), cookies that are strictly necessary to provide a service explicitly requested by the user are exempt from the requirement to obtain prior consent. Both cookies used on the Cluster subdomains fall within this exemption:

• The session cookie is necessary to maintain your authenticated state — a function you explicitly request when you log in.
• The trusted device cookie is necessary to provide the quick-login PIN feature — a function you explicitly request when you choose to save a device as trusted.

Because these cookies are strictly necessary, no cookie consent banner is displayed on Cluster subdomains.

6.2 Non-essential cookies (logbookos.com). Any analytics, marketing, or preference cookies that may be deployed on logbookos.com in the future require your prior consent before they are set, in accordance with the ePrivacy Directive. Consent is collected through the cookie consent banner on logbookos.com and can be withdrawn at any time.

6.3 GDPR legal basis. To the extent that data stored in cookies constitutes personal data (such as a session identifier linked to your account), the legal basis for processing under GDPR is Article 6(1)(b) (performance of contract) for strictly necessary cookies, and Article 6(1)(a) (consent) for non-essential cookies.

7.1 LogbookOS operates multiple independent Clusters, each on its own subdomain. Each Cluster has its own independent authentication system and database.

7.2 Cookies set by one Cluster are scoped to that Cluster’s subdomain. A session cookie set by work.logbookos.com is not readable by edu.logbookos.com, and vice versa. Likewise, a trusted device saved on one Cluster does not carry over to another.

7.3 Cookies on logbookos.com (if and when non-essential cookies are activated) are scoped to logbookos.com only. They cannot read data from, or share data with, any Cluster subdomain.

7.4 The same isolation applies across regions. Cookies set on logbookos.gr subdomains are independent from logbookos.com subdomains.

9.1 We may update this Cookie Policy from time to time — for example, if we introduce new cookies, adopt new technologies, or to reflect changes in the law. When we make changes, we will update the “Last updated” date at the top of this page.

9.2 If we introduce cookies that are not strictly necessary on any Cluster subdomain (which is not currently planned), we will: (a) update this policy before deployment, (b) implement a compliant cookie consent mechanism on the affected Cluster, and (c) not set those cookies until you have given your prior consent. We will notify you of such changes via the Platform and/or email.
