Privacy Policy: Prediction Market Tracker

Last updated: July 2026

Prediction Market Tracker is a personal tracking app for Kalshi and Polymarket. This page explains what data the app touches and where it goes.

Your portfolio data never leaves your device

Your positions, trades, balances, and tax records come directly from Kalshi's and Polymarket's own public APIs to your phone. None of it passes through any server we run. If you connect a Kalshi account, your keys are stored in your device's Keychain and are never sent anywhere except directly to Kalshi, to sign your own requests.

What our server sees, for price alerts only

iOS won't wake a closed app to check a price, so push notifications need something always running in the background. When you turn on price alerts, our alert server receives exactly three things:

• An anonymous device token from Apple, used only to address a notification to your phone
• The public ID of a market you're already watching (the same ID anyone can see on Kalshi's or Polymarket's own website)
• The price you asked to be alerted at

That's the entire list. We never receive your positions, your balances, your trade history, your tax records, your wallet address, your name, or your email. There is no account and no login for this app.

What we don't do

We don't sell data. We don't share data with advertisers or data brokers. We don't use tracking of any kind, and we don't use any third party analytics SDK.

Deleting your data

Delete all data on this device is available in Settings. It removes everything stored locally and also asks our alert server to forget your device token, so no further pushes can reach it.
