Cookie Policy

Effective Date: April 8, 2026

This Cookie Policy explains how Cohortly Inc. ("Cohortly", "we", "us", or "our") uses cookies and similar technologies when you visit our marketing website at cohortly.app and when you use the Cohortly web application. This policy should be read alongside our Privacy Policy.

1. What Are Cookies?

Cookies are small text files placed on your device (computer, tablet, or mobile) by a website when you visit it. They are widely used to make websites work efficiently, remember your preferences, and provide information to site owners. Cookies set by the website operator are called "first-party cookies"; cookies set by other parties are called "third-party cookies".

In addition to cookies, we use localStorage — a browser-based storage mechanism — to persist certain application state. Unlike cookies, localStorage data is never sent to our servers automatically; it lives only in your browser. The data stored in localStorage is listed in the cookie table below where relevant.

2. Why We Use Cookies

We use cookies and localStorage for the following purposes:

Essential

Required for the platform to function. These include authentication tokens that keep you logged in and security tokens that protect against CSRF attacks. These cannot be disabled.

Functional

Enable enhanced features and personalisation — such as remembering your dark/light mode preference, your inbox state, and saved dashboard views. Disabling these may affect your experience.

Analytics

Help us understand how users interact with Cohortly in aggregate so we can improve the product. We use Google Analytics (GA4) with IP anonymisation enabled.

Third-Party

Set by our billing partner (Lemon Squeezy) when you visit the checkout or customer portal. These are governed by Lemon Squeezy's own cookie policy.

4. Your Choices & How to Manage Cookies

Essential cookies cannot be disabled as they are strictly necessary for the Cohortly platform to function. Without them, you will not be able to log in or use the application.

For all other cookie categories, you have the following options:

Browser Settings

Most browsers allow you to view, manage, and delete cookies through their settings. Look for a "Privacy & Security" or "Cookies and Site Data" section in your browser preferences. Note that deleting cookies will log you out of Cohortly.

Google Analytics Opt-Out

You can prevent Google Analytics from collecting your data by installing the Google Analytics Opt-out Browser Add-on, available at tools.google.com/dlpage/gaoptout.

LocalStorage

You can clear localStorage data via your browser's developer tools (Application → Local Storage → cohortly.app → Clear All). This will reset your inbox state, saved views, and theme preference.

Do Not Track

If your browser sends a "Do Not Track" (DNT) signal, we will endeavour to honour it by disabling non-essential analytics tracking for your session.

5. Cookie Updates

As Cohortly evolves, we may introduce new features that set additional cookies or localStorage entries. We will update this Cookie Policy accordingly and revise the effective date at the top of the page. For changes that materially expand our use of tracking technologies, we will notify you via in-app notice or email.
