Cookies
The cookies and browser storage seenandfound.com uses: what the site needs to work and to stop bots, our visit statistics, and Meta's cookies that measure our Facebook and Instagram ads.
Browser storage
A few small notes stay in your own browser. Only PostHog's code is sent anywhere, with the visit statistics:
| Name | What it does | How long |
|---|---|---|
| sf-assistant-v1 | Keeps your open chat with the assistant, so it is still there if you come back | 7 days |
| sf-utm | Remembers which ad or link brought you, so we know which ads work | Until you close the tab |
| sf-ai-peek | Remembers the assistant already said hello, so it doesn't again | Until you close the tab |
| ph_..._posthog | PostHog's random code for your browser, so a visit counts once and a returning visitor isn't counted as new. It never names you | Until you clear it |
Advertising cookies
Meta's Pixel sets these, so we can see which of our Facebook and Instagram ads bring people here:
| Name | What it does | How long |
|---|---|---|
| _fbp | Meta's code for your browser, so it can tell a returning visitor and link a visit to our ads | 90 days |
| _fbc | Set only when you arrive by clicking one of our ads on Facebook or Instagram: which ad click brought you | 90 days |
To turn them off, use Global Privacy Control in your browser: the Pixel then doesn't load and sets no cookies, and PostHog doesn't load either. Blocking third-party trackers in your browser works too, and the rest of the site works the same.
Your control
You can block or delete cookies and site storage in your browser's settings. If you block sf_s, the scan and the assistant can't pass the bot check.
More about what we collect and why is on our privacy page.
