Cookie Policy

What Are Cookies
Cookies are small text files stored on your device by your browser. We also use localStorage, a similar browser storage mechanism.
Cookies We Use
| Name / Pattern | Provider | Purpose | Duration |
|---|---|---|---|
fsh-analytics-consent | Full Stack HVAC (localStorage) | Stores your Accept/Decline choice for analytics cookies | Persistent |
fsh-theme | Full Stack HVAC (localStorage) | Stores your light/dark theme preference | Persistent |
ph_* | PostHog | Session identification for product analytics, session replays, and heatmaps. Only set if you accept analytics cookies. | 1 year |
__stripe_* | Stripe | Payment processing and fraud prevention. Set during checkout only. | Session / 1 year |
Essential vs Analytics Cookies
- Essential: Theme preference (
fsh-theme), consent record (fsh-analytics-consent), and Stripe payment cookies are required for site functionality. These are set without separate consent. - Analytics: PostHog cookies (
ph_*) are only set after you click "Accept" on the consent banner. If you decline, no analytics cookies are set and no session data is collected by PostHog.
Managing Cookies
You can control cookies through:
- Our consent banner: Click "Decline" to prevent analytics cookies. To change your choice, clear
fsh-analytics-consentfrom your browser's localStorage (Developer Tools → Application → Local Storage). - Browser Do Not Track: We respect the Do Not Track (DNT) signal. If your browser sends DNT, PostHog analytics will not run regardless of consent banner choice.
- Browser settings: Most browsers let you block or delete cookies via their privacy settings.
