The Privacy Cost of Spellcheck
Google Chrome features a built-in spellchecker that underlines misspelled words in red as you type in text boxes on the web. By default, Chrome uses a basic, offline dictionary stored on your local hard drive. However, Google offers an “Enhanced Spell Check” feature (often labelled “Use a web service to help resolve spelling errors”).
When this enhanced mode is enabled, Chrome stops relying on the local dictionary. Instead, it takes everything you type into any text box on any website and transmits it directly to Google’s servers for analysis. While this provides superior grammar correction and recognizes new slang, it is a massive privacy risk. If you are typing sensitive corporate emails, private medical queries, or financial documents into a web portal, that text is being sent to Google. To keep your typing strictly local, you must disable the web-service spellcheck.
How to Disable Enhanced Spell Check
You can revert to the secure, offline dictionary in Chrome’s Sync and Google Services menu.
- Open Google Chrome.
- Click the three vertical dots in the top-right corner and select Settings.
- In the left-hand sidebar, click on Languages.
- Scroll down to the “Spell check” section.
- Ensure the main “Check for spelling errors when you type text on web pages” toggle is on, but look at the two radio buttons beneath it.
- You will see “Basic spell check” and “Enhanced spell check.”
- Select “Basic spell check”.
Chrome will immediately stop transmitting your keystrokes to Google’s servers. Your spelling will now be checked exclusively against the secure, offline dictionary file stored locally on your PC.
