This Cookie Policy explains how LessonLab AI ("LessonLab", "we", "us", "our") uses cookies and similar technologies when you visit our website and use our services.
This Policy should be read alongside our Privacy Policy and Terms and Conditions.
1. What Are Cookies?
Cookies are small text files that are stored on your device when you visit a website. They help websites remember information about your visit, which can make it easier to visit the site again and make the site more useful to you.
2. Our Cookie Usage
We use essential cookies that are strictly necessary for our website to function properly. These cookies do not require your consent under GDPR and ePrivacy regulations.
We also embed content from third-party services (such as YouTube videos) which may set their own cookies when you interact with that content.
3. Essential Cookies We Use
Session Cookies
- Purpose: To keep you logged in and maintain your authenticated session
- Type: Session cookie (stored via express-session with PostgreSQL)
- Duration: Session duration (deleted when you close your browser or log out)
- Why it's essential: Without this cookie, you would need to log in again on every page, making the service unusable
Authentication Tokens
- Purpose: To verify your identity and secure your account access
- Type: JWT (JSON Web Token) stored in localStorage and Authorization headers
- Duration: Varies by token type (student tokens expire after 7 days)
- Why it's essential: These tokens ensure secure communication between your browser and our servers, protecting your account from unauthorised access
Admin Mode Session
- Purpose: To remember if organisation administrators have enabled admin mode
- Type: Session variable stored server-side
- Duration: Session duration
- Why it's essential: This ensures admin users can properly access and manage organisational features
Cookie Notice Acknowledgment
- Purpose: To remember that you've acknowledged our cookie notice
- Type: LocalStorage value
- Duration: Permanent (until you clear your browser data)
- Why it's essential: This prevents the cookie banner from appearing on every visit, improving your browsing experience
4. Third-Party Cookies
Our website includes embedded content from third-party services. When you interact with this content, these services may set their own cookies on your device. We do not control these cookies.
YouTube Video Embeds
When set: When you play an embedded YouTube video on our site
Purpose: YouTube uses cookies to track video playback preferences, gather analytics, and show personalised advertisements
Common cookies include:

More information: Google Privacy Policy
Note: Third-party cookies are only set when you actively interact with embedded content (e.g., clicking play on a video). Simply visiting our pages does not trigger these cookies.
5. What We Don't Use
We want to be transparent about what we don't collect directly:
- Analytics cookies: We do not track your behaviour or collect analytics data via cookies
- Marketing cookies: We do not use cookies for advertising or retargeting
- Social media tracking: We do not embed social media tracking pixels or widgets that follow you across websites
- Preference cookies: We do not store non-essential preferences in cookies
Please note that third-party services (such as YouTube) embedded on our site may use their own analytics and advertising cookies when you interact with their content.
6. Managing Cookies
You have control over cookies through your browser settings:
- View cookies: Most browsers allow you to view which cookies are stored
- Delete cookies: You can delete all cookies or specific cookies at any time
- Block cookies: You can configure your browser to block all cookies, though this will prevent you from logging in
- Block third-party cookies: You can block third-party cookies specifically while still allowing our essential cookies
Note: If you delete or block essential cookies, you will not be able to use the authenticated features of our service. Blocking third-party cookies may affect the functionality of embedded content like videos.
7. Legal Basis
Under the General Data Protection Regulation (GDPR) and ePrivacy Directive, essential cookies that are strictly necessary for the provision of an online service do not require user consent. Our essential cookies fall into this category as they are required for:
- User authentication and session management
- Security and fraud prevention
- Maintaining user preferences for service functionality
Third-party cookies from embedded content are set by those third parties under their own privacy policies. By choosing to interact with embedded content (such as playing a YouTube video), you consent to those third parties' use of cookies in accordance with their policies.
8. Updates to This Policy
We may update this Cookie Policy from time to time to reflect changes in our practices or legal requirements. We will notify you of any material changes by posting the updated policy on this page with a new "Last updated" date.
