Cookie Policy

Last updated: July 4, 2025

1. What Are Cookies

Cookies are small text files that are placed on your device when you visit our website. They help the website remember information about your visit, such as your preferred language and other settings, to make your next visit easier and the site more useful to you.

Zertly ("we," "our," or "us") is committed to protecting your privacy. We use two broad categories of cookies:essential cookies, which are necessary for our website and services to operate, and analytics cookies (provided by Google Analytics) that help us understand how the site is used so we can improve it. Analytics cookies are disabled by default and will only be set after you give us explicit consent via the cookie banner.

2. How We Use Cookies

  • Authentication & Session Management: To keep you logged in securely while you navigate the platform.
  • Security: To protect your account and prevent fraudulent or malicious activity (e.g., to help mitigate CSRF attacks).
  • Load Balancing & Infrastructure: To ensure the website is served reliably and efficiently.

Without these cookies, many of the services you have asked for cannot be provided.

3. Types of Cookies We Use

Essential Cookies (Strictly Necessary)

These cookies are essential for the operation of our website and cannot be turned off in our systems. They are usually set only in response to actions made by you that amount to a request for services, such as logging in, setting privacy preferences, or filling in forms.

Examples:

  • • Authentication tokens (to maintain your login state)
  • • Session identifiers
  • • Security cookies to detect and prevent abuse
  • • Load-balancer cookies for consistent performance

We also use the following optional cookie category, which is only enabled after consent:

Analytics Cookies (Google Analytics)

These cookies collect aggregated information about how visitors use our site—for example, which pages are visited most often and if users get error messages from web pages. All data is anonymised and used solely to improve the performance and user experience of Zertly. We do not use any marketing or advertising cookies.

4. Third-Party Cookies

We rely on a limited number of third-party services that are necessary for Zertly to function. Any cookies these providers set are also strictly necessary.

Supabase (Authentication & Database)

Used to authenticate users securely and store data required for core functionality.

Payment Processors (e.g., Stripe)

Required for secure payment processing when you purchase a subscription.

Google Analytics

We use Google Analytics to collect anonymised usage statistics. These cookies are only set after you provide consent through the cookie banner.

Content Delivery Network (CDN)

Improves website performance by serving content from a server close to you.

5. Cookie Duration

  • Session Cookies: Deleted when you close your browser.
  • Persistent Cookies: Remain on your device for a limited period (up to 12 months) to ensure the essential features continue to work between visits.

6. Updates to This Policy

We may update this Cookie Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will post any updates on this page and, if the changes are significant, provide a more prominent notice.
