Privacy policy — Hard Facts → Anki extension

Last updated: June 1, 2026

What this extension does

The Hard Facts → Anki browser extension lets you sync flashcards from Hard Facts into Anki on your own computer using the AnkiConnect add-on. It runs only on the Hard Facts website (and localhost during development).

Data the extension handles

  • Card content — Event, date, Wikipedia links, and optional image URLs already shown on the Hard Facts page you have open. This data is read from the page and sent to AnkiConnect on 127.0.0.1:8765 on your machine to create or update Anki notes. It is not sent to Hard Facts servers by the extension for syncing.
  • AnkiConnect — Communication with your local Anki instance only.
  • Wikimedia (optional) — If you enable card images during sync, the extension downloads image files from Wikimedia/Wikipedia hosts to store in your Anki media folder. No account is required.

What we do not collect

The extension does not require a separate login, does not store your Anki collection on our servers, and does not sell or share personal data. The extension package does not load or execute remote JavaScript; all extension code is bundled in the install package.

Hard Facts website

Using Hard Facts itself (sign-in, cloud library, etc.) is governed by how you use the website and your hosting provider; that is separate from this extension, which only bridges the open tab and local Anki.

Contact

Questions about this policy or the extension can be sent to the project maintainer via the Hard Facts repository or site contact method you use for the project.
