Privacy Policy

Last updated: July 1, 2026

Polydict ("Polydict", "we", "us") operates a prediction-market and perpetual-futures (perps) trading application available as a Telegram Mini App, a Farcaster and Base Mini App, and on the web at polydict.app. This policy explains what data we process when you use Polydict and the choices you have. By using Polydict you agree to this policy.

1. Information we collect

  • Telegram account data. When you open Polydict inside Telegram, Telegram provides signed launch data (initData) containing your Telegram user ID, first/last name, username, language, and profile photo URL. We verify this signature server-side to authenticate you.
  • Farcaster / Base profile. If you sign in with Farcaster, we receive your FID, username, display name, and avatar.
  • Google or X (Twitter) account. If you sign in with Google we receive your name and email address; if you sign in with X we receive your username, display name, and profile photo. We use this only to create your Polydict profile — we do not read your Gmail, post to X, or access your timeline.
  • Wallet & on-chain data. A blockchain wallet address (an embedded wallet created for you by our auth provider, or an external wallet you connect) and the public on-chain transactions you make.
  • Usage data. Basic, largely aggregated analytics about how the app is used (pages viewed, approximate performance) to keep the service running.

We do not collect your Telegram phone number, contacts, message history, or private keys. Embedded-wallet keys are managed by our authentication provider and are never sent to us.

2. How we use your information

  • Authenticate you and keep you signed in across sessions.
  • Create or link a self-custodial wallet and display your profile.
  • Let you view markets and place, track, and settle trades.
  • Operate, secure, debug, and improve the service.
  • Comply with legal obligations and prevent abuse.

We do not sell your personal data, and we do not use it for third-party advertising.

3. Service providers

We share the minimum data needed with providers that help us run Polydict:

  • Privy — authentication and self-custodial embedded wallets.
  • Polymarket & the Polygon network — prediction-market and perps data and on-chain trade settlement.
  • Hyperliquid — perpetual-futures market data and trade execution when you trade perps there.
  • Telegram and Farcaster — the platforms the app runs inside.
  • Google and X (Twitter) — sign-in (OAuth) when you choose those login options.
  • Vercel — hosting and basic analytics.

Each provider processes data under its own privacy policy.

4. On-chain data is public

Polydict is built on public blockchains (Polygon). Wallet addresses, balances, trades, and settlements are recorded on-chain, are visible to anyone, and are permanent — they cannot be edited or deleted by us or by you. Do not use Polydict for activity you need to keep private.

5. Data retention

We keep account and profile data for as long as your account is active and as needed to provide the service or meet legal requirements. On-chain data persists on the blockchain indefinitely and is outside our control.

6. Security

We use reasonable technical measures to protect data, including server-side verification of Telegram launch data and encrypted transport (HTTPS). No method of transmission or storage is perfectly secure, and you are responsible for safeguarding access to your wallet and devices.

7. Children

Polydict is not intended for anyone under 18, and we do not knowingly collect data from children. If you believe a minor has used the service, contact us and we will take appropriate action.

8. Your rights

Depending on where you live, you may have the right to access, correct, or delete your personal data, or to object to certain processing. To make a request, email us at the address below. Note that on-chain data cannot be deleted.

9. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above, and continued use of Polydict after an update constitutes acceptance of the revised policy.
