Privacy Policy
What we don't collect
We don't ask you to create an account, and we don't collect names, email addresses, or other personal profile information. We don't run third-party advertising or analytics trackers, and we don't sell or share data with advertisers. Web fonts are self-hosted, so loading the site does not report your visit to a font CDN.
How the apps work
The UP / DOWN and UP / DOWN RACE apps run entirely in your browser. To show live prices and odds, your browser connects directly to third-party market-data providers — principally Polymarket's public APIs (market metadata and the CLOB order-book WebSocket) and public blockchain RPC endpoints. Those requests go from your device to those providers; their handling of your IP and requests is governed by their own privacy policies.
Wallets and trading
When you choose to trade, you connect your own wallet. Order signing happens client-side with your keys; we never receive or store them. Our server may return Polymarket "builder" attribution headers to enable a one-time gasless wallet setup — this involves no personal data about you. Any funds and positions live on Polymarket / the blockchain, not with us.
Multiplayer (UP / DOWN RACE)
RACE broadcasts your current, anonymous position value to a shared relay so the room can render the race. This is an ephemeral number tied to a transient session, not to your identity, and it is not persisted after the round.
Server logs & cookies
Like most websites, our server keeps short-lived operational logs (such as IP address, timestamp, and requested path) to keep the service running and secure. We use no advertising or cross-site tracking cookies. Any cookies present are strictly functional.
Children
TopK.trade is not directed to children and is intended only for adults who are legally permitted to use prediction markets in their jurisdiction.
Changes
We may update this policy; material changes will be reflected by the "last updated" date above.
