# Cookie Policy How Grey uses cookies, browser storage, and optional analytics to provide, secure, and improve the service. Last updated 30 August 2026 ## Current position Grey uses necessary cookies and browser storage for requested service behavior, security, and privacy choices. With your browser consent, Grey uses Better Stack, Cloudflare Web Analytics, and Google Analytics for optional website analytics, web performance measurement, and browser-error reporting. Signed-in product analytics are controlled by a separate account preference. Grey does not activate non-essential marketing technologies unless required consent has been obtained. ## Optional website analytics When you allow Measurement, Better Stack processes visits and interactions on Grey's public, sign-in, and sign-up pages using a persistent pseudonymous device identifier. Google Analytics measures consented visits and interactions on the same permitted pages so Grey can understand acquisition sources, landing-page engagement, and conversion paths, including alongside aggregated Google Search Console reporting. Google may process pseudonymous identifiers, page and referring URLs, interaction events, browser and device information, approximate location derived from the connection IP address, and campaign attribution parameters. Grey disables Google Signals and advertising-personalisation signals for this tag and does not send Grey account identity to Google Analytics. Cloudflare Web Analytics separately measures page views and real-user performance on the same permitted pages. Its RUM beacon processes page and referring URLs, page-load and navigation timing, resource and paint timing, Core Web Vitals, a page-load identifier, country, browser, operating system, and device type. Cloudflare discards the source IP address at the nearest data centre and does not store or read cookies, local storage, session storage, or IndexedDB for RUM. Cloudflare currently retains unsampled beacon data for seven days and makes sampled or aggregated analytics available for up to six months. Better Stack website analytics may include page and referring URLs, query parameters, click and form-submission metadata, web performance measurements, browser errors, browser and device information, and approximate location derived from the connection IP address. Grey configures analytics to limit collection to the data described here and exclude form input values. Google Analytics uses first-party cookies named "\_ga" and "\_ga\_" for pseudonymous visitor and session measurement. Grey configures these cookies to expire no later than 365 days after they are created and not to extend their expiry on later visits. Withdrawing Measurement consent disables the tag, clears these cookies, and reloads the page. Grey configures Better Stack telemetry storage in the EEA. Analytics events are retained only as long as reasonably necessary to measure usage trends, investigate service performance, and improve the service, then deleted under Grey's documented retention schedule. Better Stack may perform service operations elsewhere under the transfer safeguards described in Grey's Privacy Notice. Better Stack uses application-specific browser storage that remains until you withdraw Measurement consent, clear the site's browser data, or Grey clears it. Withdrawing consent reloads the page to stop the tag. You can withdraw consent at any time through Privacy choices. ## Optional product analytics After signing in, Grey separately asks whether you want to share product usage. If you agree, page, interaction, performance, browser-error, and Grey-defined feature events can be associated with your Grey user ID, name, work email, organisation ID, and role. Cloudflare Web Analytics separately receives page-view and real-user performance measurements for permitted signed-in pages. Grey does not send your Grey account identity to the Cloudflare RUM beacon, and Cloudflare does not use browser storage for this measurement. Page URLs can include query parameters that reflect navigation or filter state. Grey configures analytics to limit collection to the data described here and exclude form input values. The website Measurement choice does not automatically enable product analytics. Product analytics events are retained only as long as reasonably necessary to measure feature usage and improve the service, then deleted under Grey's documented retention schedule. You can change the account preference at any time under Privacy & communications in user settings. ## Consent records Grey asks for the browser choice again after up to 365 days. Grey records the choice, categories, applicable policy, and timestamps as reasonably necessary to demonstrate consent and comply with law. You can change website choices through Privacy choices. Product analytics choices are recorded separately against your account. ## Service cookies and storage Authentication and security storage supports sign-in and protects service requests. Better Stack browser storage named "\_bs" holds the persistent pseudonymous analytics identifier used only after Measurement consent. It remains until you withdraw that consent, clear the site's browser data, or Grey clears it. Google Analytics cookies named "\_ga" and "\_ga\_" hold pseudonymous visitor and session identifiers only after Measurement consent. Grey configures them to expire no later than 365 days after creation and clears them when you withdraw Measurement consent. Cloudflare Web Analytics does not set or read cookies or other browser storage for RUM measurement. The Grey cookie "grey\_landing\_locale" remembers the preferred site language for 365 days. The Grey cookie "sidebar\_state" remembers the signed-in sidebar state for 7 days. Grey local storage named "grey-theme" remembers the appearance choice until it is removed or the site's browser data is cleared. For signed-in users, browser storage may retain service data for up to 12 hours. ## Your controls Use Privacy choices in the site footer to accept, reject, or change optional categories. Use Privacy & communications in user settings to change product analytics and product-update email choices. You can also clear cookies and site data in your browser. Doing so may affect service functionality and reset your choices. ## Contact Questions and data-subject requests can be submitted through Grey's privacy request page.
