Cookies are small text files that a website stores on your device when you visit. They help the site remember information about your visit — like whether you're logged in — so you don't have to re-enter details every time.
We also use similar technologies such as local storage tokens. This policy covers all of them. Under the UK Privacy and Electronic Communications Regulations (PECR), we need your consent to set non-essential cookies.
These cookies are strictly necessary for the platform to work. They cannot be disabled and do not require consent under PECR.
| Cookie / Token | Provider | Purpose | Duration |
|---|---|---|---|
| sb-access-token | Supabase | Authenticates your active session with the CrowAgent API. Without this cookie you cannot log in. | 1 hour (auto-refreshed) |
| sb-refresh-token | Supabase | Silently refreshes your access token so your session stays active without re-login. | 60 days |
| crowagent_cookie_consent | CrowAgent | Stores your cookie consent preferences so we don't ask again on every visit. | 12 months |
We use PostHog to understand how users navigate the platform and which features are most useful. These cookies are only set after you accept analytics in our cookie consent banner.
| Cookie / Token | Provider | Purpose | Duration |
|---|---|---|---|
| ph_* | PostHog (EU cloud) | Identifies your session for aggregate product analytics — page views and feature interaction events. Data never used for advertising. PostHog is hosted on EU infrastructure. | 1 year |
PostHog privacy policy: posthog.com/privacy
Sentry captures JavaScript errors and session traces to help us fix bugs quickly. Session replay is only enabled if you accept analytics cookies. Basic error reporting (no session data) runs under legitimate interests.
| Cookie / Token | Provider | Purpose | Duration |
|---|---|---|---|
| Sentry session ID (memory) | Sentry (EU) | Groups error events from the same browser session to help us reproduce bugs. Not persisted to disk after session ends. | Session only; error logs retained 90 days |
You can control cookies in several ways:
Note: blocking essential cookies (Supabase auth tokens) will prevent you from logging in to CrowAgent.
You can withdraw or change your analytics cookie consent at any time by clicking Cookie settings in our footer. Your preference will be saved for 12 months, after which we will ask again.
You can also opt out of PostHog tracking directly at app.posthog.com/optout.
We will update this policy when we add or remove cookies. Material changes will be surfaced via the cookie consent banner.
