Upside UK

The short version

We don't sell your data. We don't collect your name, email address, or any account details. We do collect anonymous product analytics on the website and in the mobile app so we can understand what is working and improve Upside UK. No analytics event is ever labelled with who you are.

Product analytics (Mixpanel)

The website and the iOS and Android app use Mixpanel to measure anonymous usage. This is the same Mixpanel project on both surfaces, with a platform tag so we can tell web, iOS, and Android apart. Mixpanel processes this data in the European Union.

Typical events include pages and screens you open, stories you read, votes, swipes, keeps, shares, and whether onboarding or notifications were completed. On the website Mixpanel also automatically captures clicks and page views, and may record a session replay of the product interface so we can see where people get stuck. Replays are of the app, not of you as a person: we have no name, email, or account to attach them to.

Events are associated with a random anonymous identifier stored on your device (local storage in the browser; Mixpanel's own distinct id in the app). This is not linked to your name or email. You can read Mixpanel's privacy policy for how they handle data as our processor.

Votes & preferences

When you vote on a story or set reading preferences, a random anonymous ID is stored in your browser's local storage (or in secure storage on the app). This ID is not linked to any personal information and is used only to prevent duplicate votes and remember your preferences between visits. You can clear it at any time by clearing your browser's site data or reinstalling the app.

Third-party content

Story thumbnails may be served from third-party news publishers (BBC, The Guardian, etc.). Clicking "Read full story" takes you to the original publisher's website, which has its own privacy policy.

Cookies & local storage

We do not use advertising or tracking cookies from ad networks. Mixpanel stores an anonymous analytics identifier in your browser's local storage so it can tell visits apart. Dark and light mode, votes, and reading preferences also live in local storage, not in a cookie.
