Cookie Policy
Last updated: June 1, 2026
1. What Are Cookies?
Cookies are small text files placed on your device by a website. They help websites remember information about your visit, such as your login session or preferences. Cookies cannot execute code or deliver viruses — they are simply data files.
2. How We Use Cookies
ChartGPT uses cookies exclusively for the following purposes:
- Authentication — keeping you logged in across page loads using secure HTTP-only cookies.
- Session state — remembering which workspace you last worked in.
- Security — CSRF protection tokens and fraud prevention.
- Analytics — anonymised, aggregated data to understand which features are used most (no individual tracking).
3. Cookies We Set
| Cookie | Type | Purpose | Expiry |
|---|---|---|---|
| access_token | Essential | Stores your JWT access token to keep you logged in. | Session |
| refresh_token | Essential | Used to silently refresh your access token. | 30 days |
| workspace_id | Functional | Remembers your last active workspace. | 30 days |
| _vercel_analytics | Analytics | Anonymous page-view analytics (if using Vercel). | 1 year |
4. Third-Party Cookies
We do not allow third-party advertisers to set cookies on our platform. Any third-party services we integrate (e.g., Vercel Analytics) are configured to collect only anonymised, aggregated data and are bound by their own privacy policies.
5. Managing Cookies
