Cookie Policy
1. What Are Cookies
Cookies are small text files stored on your device when you visit a website. They help the site remember your preferences and understand how you interact with it.
2. Cookies We Use
Essential Cookies
These cookies are required for CampaignStack to function. They handle authentication, session management, and security. You cannot opt out of essential cookies.
- Authentication token: Keeps you signed in across pages and browser sessions
- CSRF protection: Prevents cross-site request forgery attacks
Analytics Cookies
With your consent, we use PostHog to collect anonymous usage data such as page views and feature interactions. This helps us understand how CampaignStack is used and where to improve.
- PostHog session ID: Identifies your browsing session so we can aggregate page views and feature usage. No personal data is attached.
Error Tracking Cookies
With your consent, we use Sentry to capture application errors and crashes. This helps us identify and fix bugs faster. Sentry collects technical data about errors (stack traces, browser version, OS) but no personal data.
You can opt out of analytics and error tracking cookies at any time by clearing your browser's local storage (which resets the cookie consent banner) or by using your browser's cookie settings.
Advertising Measurement Cookies
With your consent, our marketing pages load Google Tag Manager, which runs the conversion pixels of the advertising platforms we buy from (Google Ads, LinkedIn Ads). They tell us which ad brought you here and whether you signed up. Until you accept, every one of them is told that storage and personalisation are refused (Google Consent Mode). Inside the product the container loads only to report a sign-up or a purchase to Google Ads, and only Google's own tags may run there.
With the same consent, our server tells Meta and X when you sign up, when your workspace sends its first message and when you pay. It sends a SHA-256 hash of your email address and of your account id, the ad click id below, your browser's user agent (its name and version), the event, and for a payment its amount and currency. Never your name, your workspace, your leads or your IP address. No Meta or X pixel runs on our pages.
- Google Ads and LinkedIn Insight cookies: Attribute a sign-up to the ad you clicked. Set only after you accept.
- Ad click id (browser storage): The click id from the ad link that brought you (Google's gclid, Meta's fbclid, X's twclid) and a random Meta browser id, kept for up to 90 days so a later sign-up can be matched to that click. Stored only after you accept, removed when you reject.
Preference Cookies
These cookies remember your settings so you don't have to re-enter them on each visit.
- Theme preference: Stores your light/dark mode choice
3. Third-Party Cookies
CampaignStack uses PostHog for privacy-friendly analytics and Sentry for error tracking. PostHog may set cookies to track sessions. Sentry may store data in local storage to track error sessions. With your consent, Google Tag Manager loads the conversion pixels of the advertising platforms we advertise on, so they can measure that their ad led to a visit or a sign-up, and our server reports sign-ups, first messages sent and payments to Meta Platforms Ireland and X Corp. as described above. We do not sell cookie data and we run no ads on our own pages.
