Extension: Scryfall Prices — TCGplayer & Mana Pool

Last updated: July 29, 2026

Summary

This extension does not collect, store, transmit, or sell any personal information. It has no analytics, no trackers, and no advertising.

What the extension does

When you view Magic: The Gathering search results on scryfall.com, the extension displays TCGplayer and Mana Pool prices for each card and provides an optional shopping cart to collect cards for bulk purchase.

Data stored on your device

Your cart contents and cart-panel preferences (position and lock state) are stored locally on your device using the browser's IndexedDB and chrome.storage.local. This data never leaves your device and is not accessible to us. You can clear it at any time by emptying the cart or removing the extension.

Network requests

The extension contacts two third-party services to look up prices:

• Scryfall API (api.scryfall.com) — to retrieve official card data and prices, using only non-personal card identifiers (set code, collector number, Scryfall ID).
• Mana Pool API (manapool.com) — to retrieve Mana Pool prices, using only non-personal card identifiers (Scryfall ID).

No personal information is included in these requests. Your use of those services is governed by their own privacy policies.

Permissions

• storage — to save your cart and preferences locally.
• Access to scryfall.com — to display the price UI on search pages.
• Access to api.scryfall.com and manapool.com — to fetch card prices.

Data sharing

We do not sell, share, or transfer any user data. We do not collect any data to begin with.

Affiliation

This extension is an independent project and is not affiliated with, endorsed by, or sponsored by Scryfall, TCGplayer, Mana Pool, or Wizards of the Coast.
