Privacy Policy

StumbleUpon is anonymous by design. We collect as little as possible and we never sell your data or run ad trackers.

What we store

To make discovery work — remembering what you've already seen, your saved sites, and your category preferences — we store a random, anonymous device identifier in your browser. It isn't tied to your name and we don't build an advertising profile from it. If you create a Pro account, we store the email address you sign in with and your subscription status.

What we don't do

We don't sell your data, we don't run third-party ad networks, and we don't quietly profile you to decide what you're "supposed" to like. Analytics are privacy-first and aggregate.
