Cookie Policy

Effective from 1 January 2026 · © 2026 LeanTools

This Cookie Policy explains what cookies and similar tracking technologies are used on the LeanTools platform, for what purpose, and how you can manage them. This policy is compliant with the ePrivacy Directive (2002/58/EC) and GDPR.

§ 1

What Are Cookies?

Cookies are small text files (typically 4KB) stored on your device (computer, laptop, tablet) when you visit our platform. Cookies contain:

  • Session identifier — a unique code assigned to your session (e.g. "abc123xyz")
  • Preference data — e.g. selected language, theme (light/dark)
  • Timestamp — when the cookie was created and when it expires
  • Flags — whether cookies are required or optional (e.g. "_required=true")

Important: Cookies are inherently safe — they cannot contain malicious code or harm your computer. They are plain text data.

§ 2

Types of Cookies We Use

The LeanTools platform uses four main categories of cookies:

🔒 Strictly Necessary Cookies (Session)
REQUIRED

These cookies are essential for the platform to function properly. Without them you cannot log in or use any features.

Cookie Name Purpose Retention Period
session_id User session identification Until browser is closed
auth_token Storing authentication token (secure access) Until browser is closed / 30 days
user_id Storing logged-in user ID Until browser is closed
csrf_token Protection against Cross-Site Request Forgery attacks Until browser is closed
lang Remembering the selected language 12 months

Control: These cookies cannot be disabled — they are essential. They are session cookies that delete themselves automatically.

📊 Analytics Cookies
OPTIONAL

We use Google Analytics 4 (GA4) and Google Search Console to collect anonymised data about how users interact with the platform (e.g. which pages they visit, how long they stay).

Source Main Cookies Purpose Period
Google Analytics 4 _ga
_ga_*
_gid		 Session, page, time and browser tracking 2 years
Google Search Console SOCS
NID		 Tracking clicks from Google search Up to 13 months

Data: Anonymised (Google does not see your name or email, only numbers). It helps us understand which features are popular and where issues occur.

Control: You can disable these cookies, but we will not be able to see where issues occur in the app. We recommend keeping them enabled.

⚙️ Functional Cookies
OPTIONAL

These cookies remember your preferences and settings (e.g. light/dark theme, preferred table view).

Cookie Name Purpose Period
theme Remembering theme (light/dark) 12 months
board_view Remembering the last opened board view 30 days
sidebar_collapsed Sidebar state (expanded/collapsed) 12 months
notification_pref Notification preferences 12 months

Control: You can disable these cookies, but you will need to set preferences each time.

📢 Marketing Cookies
OPTIONAL

We currently do not use marketing cookies for cross-site tracking (e.g. Facebook Pixel, retargeting). If we wish to use them in the future, we will ask for your explicit consent.

No data sold: We do not sell your data to advertisers.

§ 3

How to Manage Cookies

3.1 Cookie Banner on the Website

On your first visit you will see a banner at the bottom of the page with the following options:

  • Accept all — enables all cookies (necessary + analytics + functional)
  • Reject optional — enables only strictly necessary cookies
  • Manage settings — allows you to choose individually which cookies to enable

You can change cookie settings at any time by clicking the "Cookie settings" link in the footer.

3.2 Browser Settings

You can also manage cookies directly in your browser settings:

  • Chrome: Settings → Privacy and security → Cookies and other site data
  • Firefox: Settings → Privacy & Security → Cookies and Site Data
  • Safari: Preferences → Privacy → Manage Website Data
  • Edge: Settings → Privacy, search, and services → Clear browsing data

You can also delete all cookies or choose which sites may store them.

3.3 Opting Out of GA4 Cookies

If you do not wish to be tracked by Google Analytics, you can:

Important: Disabling analytics cookies will not affect platform functionality — you will be able to work normally. We simply will not see data about your usage.
§ 4

Third-Party Cookies

The LeanTools platform uses services from providers that may store their own cookies:

We do not have full control over third-party cookies, but we guarantee that only those that are strictly necessary are enabled by default.

§ 5

Cookie Security

5.1 Security Attributes

All our cookies are transmitted with the following security attributes:

  • HttpOnly — not accessible to JavaScript (XSS protection)
  • Secure — transmitted only over HTTPS (encrypted)
  • SameSite — CSRF protection, cookies sent only to the same domain
5.2 Privacy

Cookies do not store:

  • Passwords (passwords are never sent in cookies)
  • Credit card data (handled by a secure payment gateway)
  • Personal data (names, addresses — unless in a session, which is temporary)
§ 6

Changes to the Cookie Policy

We may update this policy when:

  • We add new cookies (e.g. a new analytics tool)
  • We change providers (e.g. replace Google Analytics with another)
