Last updated: 9 November 2026.
This policy explains how Nightscout Pro Ltd uses cookies and browser storage on its public website at nightscoutpro.com and its preview site. The account portal, legacy billing website and payment providers are separate services.
Your choice
Optional measurement is off until you allow it. On the public site, the consent panel enables both our source tracking and Google Analytics; the preview uses source tracking only. Declining does not prevent browsing, signup or payment. You can change your choice at any time.
Site preferences and consent records
Cookies are sent to the relevant website with requests. Local storage and session storage keep information in your browser. We use the following items to remember choices you make and support the features you request; they do not enable optional measurement.
| Name and storage type | Purpose and provider | How long it stays |
|---|---|---|
nsp_site_languageLocal storage | Nightscout Pro: remembers the language you select. | Until you clear site data in your browser. |
nsp_site_currencyLocal storage | Nightscout Pro: remembers the currency you select, independently of language. | Until you clear site data in your browser. |
nsp_site_countrySession storage | Nightscout Pro: caches an approximate country code from our Cloudflare connection to suggest a currency. It does not store your precise location. | For the browser tab session. The cached country is reused for up to 30 minutes. |
nsp_acq_choicensp_ga_choiceCookies | Nightscout Pro: remembers whether you allowed or declined source tracking and Google Analytics. | 90 days. |
nsp_acq_revokeCookie | Nightscout Pro: remembers a request to stop source tracking if the service cannot be reached, so we can complete your choice. | Until acknowledged, or up to 90 days. |
Optional source tracking
With permission, we record the original referring domain, public landing page, campaign tags and visit time. A random token links this source to signup and verified payment when you continue to our account portal. Source and campaign details may also accompany the corresponding Stripe checkout and subscription.
| Name and storage type | Purpose and provider | How long it stays |
|---|---|---|
nsp_acq_firstCookie | Nightscout Pro: remembers the consented source visit or its random token on the public website. | Up to 90 days from the source visit. |
nsp_acqCookie | Nightscout Pro: carries the same source token on my.nightscoutpro.com after you follow a link to the account portal. | Until the source visit expires, up to 90 days. |
This source record does not contain health readings, full referral URLs, advertising click identifiers, IP addresses or browser fingerprints. Unlinked source records are deleted after their 90-day expiry. Records linked to an account remain with that account until it is deleted; withdrawal stops future attribution and excludes the source from our source report.
Optional Google Analytics
Google Analytics uses cookies to distinguish browsers and sessions and produce reports about visits to public pages. Google receives page titles, public page addresses, browser and device information, and normal connection information when its tag loads.
| Name and storage type | Purpose and provider | How long it stays |
|---|---|---|
_ga_ga_XHYKJN9XT8Cookies | Google Analytics: measures website visits and sessions. These cookies are set only after you allow optional measurement. | Up to 90 days. |
We exclude URL query strings and fragments from page addresses and reduce referral addresses to their domain. We do not send account details, health readings, form values or source tracking tokens to Google. Advertising features are disabled. Google Analytics is not loaded on the preview site or inside the embedded app demo.
Interactive app demo
| Name and storage type | Purpose and provider | How long it stays |
|---|---|---|
nightscout_demo_v1.*Local storage | Nightscout Pro: keeps demo settings and edits to fictional sample records on this device. This is separate from your live Nightscout account. | Until you reset the demo or clear site data in your browser. |
Delivery, account and payment services
Cloudflare delivers and protects this website and provides the approximate country lookup. The lookup stores only the country code in the session item listed above, rather than a precise location.
Signing in, support and payment take place on separate services, including my.nightscoutpro.com, legacy.nightscoutpro.com and Stripe. They can use additional authentication, security and payment storage. The table above lists only the source tracking cookie used for the account portal handoff, not every cookie used by those separate services.
Your browser may retain cookies from an earlier website or a visit to the legacy billing site. The new public website does not set the old WordPress, shopping cart or advertising cookies listed in our previous policy.
Changing or withdrawing permission
Use Measurement preferences on this page or in the footer. Choosing No thanks stops future optional measurement, removes the public website source token and Google Analytics cookies, and asks our service to stop linked source tracking. If the service cannot be reached immediately, the pending request cookie enables another attempt.
Withdrawal does not erase information already received by Google or account records that must be retained. See our privacy and data retention policies for more information.
Privacy policy · Data retention policy
You can also block or delete cookies and browser storage in your browser settings. Clearing site data removes saved preferences and consent choices, so we may ask again. Language and currency preferences are stored only when you select them; automatic currency suggestions are not saved as a permanent choice.

We will update this policy when the website storage we use changes. For questions about cookies or privacy, contact Nightscout Pro Ltd:
