1.What are cookies?
A cookie is a small text file that a website stores on your browser. Cookies remember things — your preferences, your session, which pages you've seen.
This Cookie Policy explains which cookies Penumbra uses, why, and how you can manage them. It covers cookies and similar technologies (like web beacons, pixels, and local storage). For simplicity, we'll just call them all "cookies."
2.Cookies we use
Cookies on penumbra.health fall into three categories.
Required for the site to function — for example, to remember your cookie preferences, prevent fraud, and keep you signed in (when applicable). You can't reject these without breaking the site.
| Cookie | Set by | Purpose | Lifespan |
|---|---|---|---|
cookie_consent | penumbra.health | Stores your cookie preference choices | 1 year |
session_id | penumbra.health | Maintains your session on the site | Session |
__cf_bm | Cloudflare | Bot protection and security | 30 minutes |
Help us understand how visitors find and use our site. We use this data in aggregate — we don't try to identify individual visitors from it.
| Cookie | Set by | Purpose | Lifespan |
|---|---|---|---|
_ga | Google Analytics | Distinguishes unique visitors | 2 years |
_ga_<container-id> | Google Analytics 4 | Stores session state | 2 years |
_gid | Google Analytics | Distinguishes unique visitors | 24 hours |
| GTM container | Google Tag Manager | Loads other tags (analytics, advertising) | Session |
(Google Search Console doesn't set cookies — it uses a verification meta tag or file. We mention it here because it's part of our analytics stack.)
Let us show you relevant ads on Meta (Facebook, Instagram) and Google, and measure how those ads perform.
| Cookie | Set by | Purpose | Lifespan |
|---|---|---|---|
_fbp | Meta Pixel | Identifies your browser for ad measurement | 90 days |
_fbc | Meta Pixel | Stores last-click data for ad attribution | 90 days |
_gcl_au | Google Ads | Conversion measurement | 90 days |
IDE | Google DoubleClick | Ad targeting and measurement | 13 months |
NID | User preferences for Google ads | 6 months |
If we add new cookies in the future (such as heatmap or session-recording tools), we'll update this list and may ask for renewed consent if required.
3.Your choices
You're in control of optional cookies.
Via our cookie banner
When you first visit penumbra.health, you'll see a cookie banner. You can Accept all (turn on all cookies), Reject optional (only strictly necessary cookies will load), or Customize (choose by category — analytics / advertising). You can change your choice anytime by clicking "Cookie settings" in the site footer.
Via your browser
You can also manage cookies in your browser settings:
- Chrome: Settings → Privacy and security → Cookies
- Safari: Settings → Privacy → Manage Website Data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Edge: Settings → Cookies and site permissions → Cookies
Note that blocking essential cookies may break parts of the site.
Via the advertising platforms
You can also opt out of personalized advertising directly:
- Meta (Facebook, Instagram): facebook.com/help/568137493302217
- Google: adssettings.google.com
- General opt-out (US): optout.aboutads.info or optout.networkadvertising.org
4.Do Not Track (DNT)
Some browsers can send a "Do Not Track" (DNT) signal. There's no industry-standard response to DNT, so we currently don't change our behavior based on it. You can still control cookies via the methods above.
We do, however, honor the Global Privacy Control (GPC) signal: where your browser sends GPC, we treat it as a request to opt out of the "sale"/"sharing" of your personal information for advertising. See our California Privacy Rights notice for details.
5.Cookies and personal data
Some cookies (especially advertising cookies) can be considered personal data under laws like CCPA, GDPR, and the UK Data Protection Act. How we handle that data is covered in our Privacy Policy and the regional addenda.
6.Changes to this policy
When we add, remove, or change cookies, we'll update this Cookie Policy and change the "Effective Date" at the top. The current version is always at https://www.penumbra.health/penumbra-cookies.html.
