GOG Enhancer

About

GOG Enhancer is an unofficial third-party browser extension that adds the
features GOG.com does not ship with — without any analytics, ads, or remote
code.

▸ Live currency conversion
  Converts USD prices to ILS, EUR, GBP, PLN, or RUB using exchange rates
  fetched from frankfurter.app (a free, public, ECB-backed rate service).
  Detects the page's existing currency so it never double-converts.

▸ Price-history tracking
  Records a small price snapshot every time you visit a game page.
  Shows current vs. all-time-low vs. average on a sparkline you can review
  any time. Fully local — no server.

▸ IsThereAnyDeal compare button
  One click on a game page opens an IsThereAnyDeal search for the same
  title across Steam, Epic, Humble, and other stores.

▸ Personal tags & notes
  Add private tags ("co-op weekend", "after I finish Witcher 3") and notes
  to any game. A separate dashboard page lets you search, filter, and
  export to CSV.

▸ Hebrew translations + RTL
  Optional Hebrew dictionary covering navigation, UI strings, and common
  patterns. Real RTL with logical-property CSS — not a flipped page.

▸ Wishlist sale alerts
  When you visit your wishlist, a small badge appears on the toolbar icon
  with the count of items currently on sale.

▸ Visual upgrade (optional)
  System-font monospace numerals for prices, era-aware accents on classic
  vs. modern game covers, gold pill on "Good Old Game" markers.

▸ Privacy-first
  No analytics, no third-party tracking, no Google Fonts, no remote code.
  All your tags, notes, and history stay on your device. Two outbound
  requests only: exchange rates from frankfurter.app and the public GOG
  mods catalog. Both omit cookies and identifying information.

▸ Open source under the MIT license. Verifiable end-to-end.

DISCLAIMER: This is an unofficial third-party tool. It is not affiliated
with, endorsed by, or sponsored by GOG sp. z o.o. or CD Projekt S.A.
The "GOG" name is used nominatively to describe the website the extension
works with.
