Privacy Policy

Effective November 9, 2026

Ghosthand is a browser extension and a Mac app ("Ghosthand for Mac") that type text you paste into them, with a human typing rhythm. It is operated by Ghosthand ("we", "us"), based in Quebec, Canada. This policy explains what information Ghosthand, Ghosthand for Mac and this website handle, and why. The short version: the text you type never leaves your computer, and we keep only what's needed to run the free trial and your license.

What stays on your computer

The text you paste into Ghosthand, the documents it types into, your keystrokes and your settings are processed only inside your browser. Your draft and settings are saved in your browser's local extension storage. We never receive, read, store or sell them.

The same goes for Ghosthand for Mac: your text, your documents and your settings stay on your Mac. To paste a quotation or reference in one stroke, the app briefly puts it on your Mac's clipboard and then puts your own clipboard content back.

What we collect (browser extension)

When you sign in with Google, Ghosthand asks Google only for your basic identity (the openid and email permissions). We then store, for your account:

• Your Google account ID (a number Google assigns to your account) and your email address, to recognise you on any computer you sign in on;
• the number of free-trial words you have typed (a count, never the words themselves);
• whether you bought the lifetime license, and for purchases the Stripe payment reference, customer reference, amount, currency and date;
• the dates your account was created and last updated.

We do not collect your name, photo, contacts, browsing history, location or any other Google data, and Ghosthand contains no ads, analytics or tracking.

What we collect (Ghosthand for Mac)

Ghosthand for Mac has no sign-in. Its license belongs to the Mac it runs on, so we store, for each Mac:

• an anonymous ID for the Mac: a one-way hash of its hardware ID, computed on the Mac. The hardware ID itself never leaves your computer, and the hash can't be turned back into it;
• the number of free-trial words typed on that Mac (a count, never the words themselves) and the version of the app;
• whether a license was bought for that Mac, and for purchases the Stripe payment reference, customer reference, the email address you gave Stripe, amount, currency and date;
• the dates the record was created and last updated.

The app's only network calls go to our license server (and to GitHub when you download it). It contains no ads, analytics or tracking.

How we use it

• To count your 500 free words and stop the trial when they are used up;
• to unlock Ghosthand after you pay, on every computer where you sign in (for the Mac app: on the Mac you bought it for);
• to answer support requests and prevent abuse of the free trial.

We don't use your information for advertising, we don't sell it, and we don't share it except with the service providers below.

Google user data

Ghosthand for Mac does not use Google sign-in. The browser extension's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We use your Google account ID and email only to provide the sign-in, free trial and license features described here.

Payments

Payments are processed by Stripe on Stripe's own secure page. Your card or wallet details go directly to Stripe; we never see or store them. Stripe tells us that a payment succeeded and gives us the references listed above.

Service providers

• Google: "Sign in with Google" (Google Privacy Policy).
• Stripe: payment processing (Stripe Privacy Policy).
• Supabase: hosts our account database and server functions, in Canada (Supabase Privacy Policy).
• GitHub: hosts the Ghosthand for Mac downloads; GitHub receives your IP address when you download the app (GitHub Privacy Statement).

This website loads its fonts from Google Fonts, which receives your IP address when you visit. The website sets no cookies of its own.

Extension permissions

• debugger: sends real keystrokes to the page you choose (this shows Chrome's "started debugging this browser" bar);
• tabs, sidePanel: shows which tab Ghosthand types into, in its side panel;
• storage: saves your draft, settings and account status locally;
• identity: opens the Sign in with Google window;
• notifications, clipboardRead: progress notifications and the "Paste from clipboard" button.

Mac app permissions

• Accessibility: lets Ghosthand press keys in the app you choose. It is the only permission it asks for: it doesn't read your keyboard (no Input Monitoring) or your screen (no Screen Recording).

How long we keep it

We keep your account information for as long as your account exists, so your license keeps working. Purchase records may be kept longer where tax or accounting law requires it. You can ask us to delete your account at any time (see below); a deleted account loses its license.

Your rights

You can ask us to access, correct, export or delete the information we hold about you, or to stop processing it, by emailing ghosthandwriter@gmail.com (for the Mac app, include the Mac's ID from ? → Copy this Mac's ID). We answer within 30 days. Signing out of Ghosthand removes your account information from that browser. You can also remove Ghosthand's access to your Google account at myaccount.google.com/permissions.

The person in charge of protecting personal information at Ghosthand can be reached at ghosthandwriter@gmail.com.

Security

Account data is stored in a database that only our server functions can access, over encrypted connections. Sign-in tokens are checked with Google on every request.

Children

Ghosthand is not directed at children under 13 and we do not knowingly collect information from them. If you believe a child has given us information, contact us and we will delete it.

Changes

If we change this policy, we'll update the date at the top and, for significant changes, tell you in the extension or the app before they apply.
