1. What are cookies?
Cookies are small text files that websites store in your browser to remember information about your visit.
2. What cookies does this site use?
Neither this website (cofactu.com) nor the application (app.cofactu.com) sets any tracking cookie until you expressly accept it in the banner. With your consent, both use advertising measurement cookies (Google Ads, to know which ads bring sign-ups) and usage analytics cookies (PostHog). The application additionally uses technical cookies necessary for operation (Better Auth session), which do not require consent.
Technical cookies (necessary — no consent required)
| Cookie | Owner | Purpose | Duration |
|---|---|---|---|
better-auth.session_token | Cofactu (first-party) | Keeping you signed in on app.cofactu.com | 30 days or until logout |
cofactu_consent (cookie on .cofactu.com, with a cookie-consent copy in localStorage) | Cofactu (first-party) | Remembering your decision about optional cookies (accept/reject). One decision, valid on both cofactu.com and app.cofactu.com | 180 days, or until you change it or clear storage |
Measurement and advertising cookies (optional — only with your consent)
| Cookie | Owner | Purpose | Duration |
|---|---|---|---|
ph_<project-key>_posthog (cookie on .cofactu.com and its localStorage copy) | PostHog (processor, EU servers) | Usage analytics on cofactu.com and app.cofactu.com: a random device identifier and aggregated events (pages viewed, buttons clicked, features used) to see where people get stuck and improve the product. Not used for advertising and not shared with third parties for their own purposes | 365 days |
_gcl_au, _gcl_aw, _gcl_gs | Google Ireland Ltd (Google Ads) | Conversion measurement: knowing whether a sign-up on app.cofactu.com came from a Google ad, and which one. Set on .cofactu.com only after you accept | 90 days |
IDE, test_cookie (doubleclick.net domain) | Google Ireland Ltd | Third-party cookies Google may set when its tag loads with advertising consent granted (measurement and personalisation of Google ads) | Up to 13 months (test_cookie: 15 minutes) |
These cookies are not set until you expressly accept them in the first-visit banner. If you reject them, analytics is fully disabled.
3. How to manage or withdraw your consent
Withdrawing consent is as easy as giving it, at any time:
- From the app: Profile → the "Cookie preferences" button reopens the banner and lets you change your decision (accept → reject or vice versa). This control is permanently available, not just on the first visit.
- From your browser: you can delete the site's cookies and local storage from your browser settings; on your next visit the banner will ask again.
When you withdraw consent, analytics capture stops immediately. Data already collected is kept for at most 12 months (see the privacy policy).
