What is Polyteller?

The extension converts event end times to your local zone and keeps a live countdown. It handles daylight-saving changes, warns around transitions and updates when the selected market changes, or provides a refresh hint when needed.

Privacy Mode masks displayed balances and portfolio values across open Polymarket tabs and remembers the preference between browser sessions. This helps with screen sharing, but does not hide every possible identifying element.

Who it is for

  • Users tracking deadlines across time zones.
  • Streamers and screen sharers hiding portfolio amounts.
  • Traders who want an optional confirmation before an order click proceeds.

Features and coverage

  • Local deadlines and navigation

    The countdown follows the event end time, handles daylight saving and responds to market navigation with an update or refresh hint.

  • Multiple reminders

    Set several advance-notification times for an event. Delivery depends on browser and operating-system permissions and background behavior.

  • Persistent portfolio masking

    Privacy Mode immediately masks displayed balances and portfolio values across open Polymarket tabs and preserves the setting between sessions.

  • Optional trade confirmation

    Trade Safety adds a prompt with Enter to confirm and Escape to cancel. The provider says the dialog is automatically disabled on small screens.

  • Chromium browser support

    The provider lists Chrome 110+ and compatible Chromium browsers, including Edge and Brave.

Workflows with Polyteller

Prepare a screen share

Enable Privacy Mode, inspect every visible Polymarket tab and verify that the amounts you intend to hide are masked.

Follow a deadline

Check the event’s local end time and countdown, then set the reminder intervals you need.

Add a click check

Enable Trade Safety and inspect its confirmation behavior at the viewport size you actually use.

Pricing and total cost

The extension is advertised as free through the Chrome Web Store.

Getting started

Before you start: The countdown tracks an event time, not a promise of immediate settlement.

  1. Install from the official Chrome Web Store listing.
  2. Open Polymarket, optionally pin the extension, and check the event end time and local zone.
  3. Configure reminder times and allow the required browser notifications.
  4. Enable Privacy Mode before screen sharing and Trade Safety if you want an additional confirmation.

Trade-confirmation dialogs are disabled on small screens according to the provider; check the actual browser size you use.

    Our take on Polyteller

    The extension addresses specific timing, screen-sharing and accidental-click problems. Persistent masking and multiple reminders are useful conveniences, while screen-size exceptions and notification dependencies limit how much users can rely on the prompts alone.

    Frequently asked questions about Polyteller

    Does masking work across tabs?

    The product describes immediate masking across open Polymarket tabs, with the preference retained between browser sessions.

    Can I schedule several reminders?

    Yes. Several notification times before the event ends are supported, subject to browser and operating-system delivery conditions.

    Does Trade Safety work on a small screen?

    The provider says the confirmation dialog is automatically disabled on small screens. Inspect its behavior at your actual viewport size.

    Does the countdown change resolution rules?

    No. It adds timing controls to the page; event end time and market settlement can be separate processes.
