Typefix

Privacy Policy

Last updated: 2026-07-19

Typefix is a private writing assistant: a Chrome extension that checks spelling and grammar as you type and can rewrite or polish text with AI on demand. This policy explains exactly what happens to your text and the little data we keep. The short version: on-device checks never leave your browser, and our server stores none of the text you write.

On-device checking, by default

Spelling and grammar checking runs entirely on your device. Typefix uses the Harper checker compiled to WebAssembly and running inside the extension, so the underlines you see as you type are produced locally and work offline. No text leaves your browser for these on-device checks.

Optional AI features

When you sign in with your Google account, you can use Typefix’s AI features: rewrites, tone changes, drafting, and a deeper AI grammar pass. For these, the specific text you select or are actively writing is sent to the Typefix server (the /api/check endpoint), which forwards it to Anthropic’s API to produce the check or rewrite and returns the result to your browser.

The server does not store that text; it is processed in memory to generate the response and then discarded. If you prefer, you can limit AI to on-demand rewrites only (turning off the continuous AI grammar pass) in the extension’s options. Any AI results that are cached for reuse are cached locally on your device, never on the server.

The Typefix server stores no text you write. For AI requests it records only metadata; see “What we store” below.

The one exception: suggestion diagnostics

During the scandiweb internal pilot, there is a broader but still deliberately scoped exception, used only to improve suggestion quality. For accounts on the pilot allowlist (currently the scandiweb.com domain, plus a small number of development accounts), Typefix stores a short snippet of text around a flagged suggestion, plus which rule fired, which engine produced it, how confident it was, and what you did with it: applied it, moved on without using it, or marked it as not helpful.

This can be turned off at any time from the extension’s Options page (the “Share flagged snippets to improve Typefix” toggle). For every account not on the pilot allowlist, this endpoint stays a no-op: the server drops the data and stores nothing. If your account is not on the pilot allowlist, no text you write is ever stored.

What we store (metadata only)

For accounts that use the AI tier, we keep a small amount of metadata, never the text you write:

Permissions and scope

Typefix only looks at the text in editable fields on the pages you visit: the box you are typing in. Content elsewhere on the page is not read or collected.

The extension requests broad host access (<all_urls>) for one reason: so that underlines and fixes work in editable fields on every site, rather than a preselected few. It is not used to read or transmit page content beyond the text you write.

What we don’t do

Subprocessors

Typefix relies on a small set of service providers:
