Cookie Policy
Last updated: February 28, 2026
This Cookie Policy explains what cookies are, how Friday, Inc. ("we", "our", "us") uses them on friday.so and mail.friday.so, and how you can manage your preferences.
What Are Cookies?
Cookies are small text files placed on your device by a website. They allow the website to remember information about your visit — such as your preferred settings or whether you are logged in — to improve your experience on subsequent visits.
Similar technologies include pixel tags (small transparent images embedded in web pages or emails) and local storage (browser-side key-value storage used as an alternative to cookies).
Cookies We Use
Essential Cookies
These cookies are strictly necessary for the Service to function. They cannot be disabled without breaking core functionality such as authentication.
| Name | Provider | Purpose | Type | Expiration |
|---|---|---|---|---|
sb-* (Supabase session) | Supabase | Stores your authentication session token so you remain logged in | HTTP cookie | Session / configurable |
Analytics Cookies
These cookies help us understand how visitors interact with our website so we can improve it. By using the Service, you consent to the use of analytics cookies as described in our Privacy Policy.
| Name | Provider | Purpose | Type | Expiration |
|---|---|---|---|---|
ph_* (PostHog) | PostHog (proxied via friday.so/ingest) | Records page views, interactions, heatmaps, and session recordings for product analytics | HTTP cookie + localStorage | 1 year |
_vercel_* | Vercel | Anonymous, aggregated page view analytics | HTTP cookie | Session |
PostHog is proxied through our own domain (friday.so/ingest) rather than loaded directly from posthog.com. This means your browser communicates with our servers rather than PostHog's servers directly.
Third-Party Embed Cookies
These cookies may be set by third-party services when you interact with embedded content on our site. We do not control these cookies.
| Name | Provider | Purpose | Type | Expiration |
|---|---|---|---|---|
Various (VISITOR_INFO1_LIVE, YSC, etc.) | YouTube (Google) | Tracks video views and user preferences when you play an embedded video | HTTP cookie | Up to 2 years |
Various (guest_id, twid, etc.) | Twitter/X | Set when embedded tweets are displayed on our blog | HTTP cookie | Up to 2 years |
