What's On? — Last updated: 5 August 2026
This page explains the cookies used by the What's On? web app at whatson-events.com. What's On? is operated by WHATS ON EVENTS LTD (company number 17375595), registered office 71-75 Shelton Street, Covent Garden, London, United Kingdom, WC2H 9JQ. This page covers the web app only. If you use our Android or iOS app, no cookies are set — see the Analytics section of our Privacy Policy for how mobile analytics works. Mobile advertising consent (Google AdMob / UMP) is a separate mechanism, is not a cookie, and is described in our Privacy Policy — it is not covered by this page.
On first visit in a web browser, a banner asks whether you accept or decline analytics cookies. No analytics cookies are set until you accept. If you decline, or close the banner without choosing, analytics remains off for that browser.
The cookies we set once you accept are:
_ga — Google Analytics 4 user identifier. Distinguishes
unique users across sessions. Default expiry is 2 years from
last update; browsers may shorten that (for example Safari ITP or Chrome’s
maximum cookie lifetime)._ga_<container-id> — Google Analytics 4 session state
for the measurement stream. Default expiry is 2 years from
last update, subject to the same browser limits.When you sign in, FlutterFire persists your Firebase Authentication state in the browser’s IndexedDB (the web SDK default; this app does not override persistence). That storage is strictly necessary for a service you have explicitly requested (staying signed in to your account) and does not require consent under UK PECR. It is unaffected by your analytics-cookie choice below.
You can accept or decline analytics cookies at any time. Open the app, tap the account icon, go to Preferences, and tap Analytics cookies to change your choice. If you decline after previously accepting, we stop analytics collection for that browser and remove the analytics cookies listed above.
For Google Analytics 4, our property’s data-retention setting (currently up to 14 months) applies to user-level and event-level data used in explorations and similar features. It does not limit standard aggregated reports, which Google may retain for the life of the property. We do not currently export analytics events to BigQuery or other linked products with a separate retention policy. You can request deletion of analytics data that relates to you by emailing privacy@whatson-events.com. See the Analytics section of our Privacy Policy for full details of the deletion process and international data transfers.
This page should be read alongside our Privacy Policy, which covers all other personal data we collect and process. See also our full list of legal documents.
We may update this policy as the app evolves. Material changes will be communicated in-app or by email. The "Last updated" date at the top of this page will always reflect the most recent revision.
