PolyAPY — Privacy Policy
PolyAPY is a browser extension that adds live liquidity-provision reward estimates to Polymarket's rewards page, and a companion dashboard for browsing markets and running the reward calculator. This page explains exactly what data the extension touches, where it goes, and what it doesn't do. PolyAPY is an independent, community-built tool and is not affiliated with, endorsed by, or sponsored by Polymarket.
✕ No data collection
Nothing PolyAPY touches is sent to any server we operate. We don't have a server.
✕ No accounts, no wallet access
PolyAPY never reads your Polymarket account, positions, balance, or wallet, and cannot place trades.
✕ No tracking or analytics
No ads, no analytics scripts, no third-party trackers of any kind.
✓ Preferences stay on your device
Your stake, spread, and display settings are stored locally via the browser's own storage.
What PolyAPY stores
Everything PolyAPY remembers is stored using the browser's built-in
extension storage (chrome.storage), on your own device. If
you're signed into Chrome sync, this storage syncs the same way any other
extension's settings do — through your own Google account, not through us.
We never receive a copy of it.
| What's stored | Why |
|---|---|
| Your reward-calculator stake and spread distance | So the estimates on the rewards page reflect your own inputs, without re-entering them every visit. |
| Display settings (12/24-hour clock, countdown color thresholds, default calculator values) | So the dashboard renders the way you last configured it. |
| A local cache of public market listings (titles, start times, reward pool figures) | So the dashboard's browse and filter view doesn't have to re-fetch everything on every open. This is public market data from Polymarket, not data about you. |
None of the above identifies you personally, and none of it leaves your browser.
What PolyAPY sends over the network, and to whom
To compute reward estimates, PolyAPY's background service worker fetches public market and order-book data directly from Polymarket's own public APIs — the same data Polymarket's own website reads:
gamma-api.polymarket.com— public market and event metadata (questions, reward pool parameters, start/end times).clob.polymarket.com— public order-book data (bids/asks), used to estimate competing liquidity.
These requests carry no personal information — no account identifiers, no wallet address, nothing that identifies you. They're the same kind of request your browser would make just by loading Polymarket's own pages. PolyAPY does not operate any backend server of its own, so there is nowhere else for this data to go.
What PolyAPY does not do
- Does not collect personally identifiable information (name, email, address, etc.)
- Does not read or transmit financial, payment, authentication, or wallet data
- Does not read your Polymarket account, positions, or trading history
- Does not place trades or move funds — it is read-only
- Does not track your browsing history or activity outside Polymarket's own pages
- Does not use cookies, fingerprinting, or any analytics/advertising service
- Does not sell, rent, or transfer any data to third parties
- Does not run any code that isn't shipped inside the extension package itself (no remotely loaded scripts)
