Cookie Policy

ProCul uses cookies and similar browser technologies to operate procul.app. This page explains what we use, why, and how to control them.

1. What is a cookie?

A cookie is a small text file that a website asks your browser to store. It can hold an identifier, a preference, or a session token. Cookies are per-domain — procul.app cannot read cookies set by another website.

2. Categories we use

• Strictly necessary. Session cookies issued by Supabase Auth so you stay signed in. Without these the Service cannot function. Cannot be disabled.
• Preferences. Your UI choices — collapsed sidebar state, last-used RFQ category. Purely for your convenience.
• Analytics. Aggregated page-view counts and anonymized telemetry. Helps us prioritize features. You can disable these in your browser; see below.
• Marketing. We currently run none. If we introduce a retargeting pixel in the future, we will update this page and request consent.

3. Third-party cookies

Some features rely on third-party scripts which may set their own cookies:

• Supabase — session + refresh tokens. Strictly necessary.
• Vercel — infrastructure routing cookies and Speed-Insights. Anonymized.
• Payment processor (Pro tier) — fraud and 3DS verification cookies at checkout. Strictly necessary for transactions.

4. How to control cookies

• Your browser's settings let you accept, reject, or delete cookies on a per-domain basis. Chrome, Safari, Firefox, and Edge all support this.
• Disabling strictly-necessary cookies will prevent you from signing in to ProCul.
• We respect the Do-Not-Track header: when set, we disable analytics cookies automatically.

5. Retention

• Session cookies: expire when you close your browser.
• Auth refresh token: 30 days of inactivity.
• Preference cookies: 12 months.
• Analytics cookies: 13 months maximum.

6. Changes

We may update this Cookie Policy. Material changes are notified on procul.app and, where material, emailed to account holders.
