Privacy Policy

PredCheck has no accounts, no sign-up and no wallet connection. It never asks for a private key, a seed phrase or a signature, and it cannot place a trade on your behalf.

We do not sell data and we do not store raw IP addresses. Google Analytics measures how many people visit; nothing it collects feeds any ranking on this site.

Two first-party events are recorded, and only to tell us whether the site is being used at all:

• A trader search — the search term, the trader it resolved to, and a timestamp.
• A trader profile view — the trader viewed, and a timestamp.

Each event carries a visitor identifier, which is a salted SHA-256 hash of your IP address and browser user-agent. The raw IP address is never written to the database, and the hash cannot be reversed to recover it.

That identifier exists so repeated events from one visitor can be collapsed into a single count. It is not used to build a profile of you, it is not linked to anything else, and it has no bearing on any public ranking — Hot Traders is computed from settled trading results and reads no interaction data at all.

Traffic that identifies itself as a crawler or bot is excluded before any event is written.

The trading data shown on PredCheck — wallet addresses, fills, prices and settlements — is public on-chain and public venue data. It is not personal information you have given us, and PredCheck does not link it to any visitor.

PredCheck is not the source of this data and cannot amend, remove or dispute records held on a public blockchain or by the venue.

PredCheck sets no cookies of its own for tracking. Your light or dark theme preference and your watchlist are kept in your browser’s local storage, on your device only, and are never sent to us. The watchlist needs no account, and because it lives on the device it does not follow you to another browser.

Google Analytics sets its own cookies so that repeat visits are not counted as new ones. Clearing them, or blocking them in your browser, does not affect anything on the site.

Analytics events are only useful as a short-term usage signal and are retained briefly. Public trading data is retained so that historical metrics can be recomputed if the accounting logic improves.

PredCheck reads public Polymarket APIs from its own servers. Your browser does not contact them, and no request from your browser is shared with the venue.

Google Analytics runs in your browser and reports page views to Google. It receives your IP address, which Google uses to derive an approximate location and then discards rather than storing. What Google collects is governed by Google’s own privacy policy.

If advertising is enabled in future, it will be disclosed here before it is switched on, and the ad provider’s own policies will apply to what it collects.

This policy may be updated as the product changes. Material changes will be reflected in the date above. Questions can be sent to [email protected].
