Privacy — in plain English
Your typing patterns belong to you.
SmashKey is built around a simple principle: the things you teach SmashKey are yours, stay on your device, and don't get accumulated anywhere we can see them.
What stays on your device
Your input — every "what you typed → what you meant" example SmashKey learns from — lives entirely in a local file on your computer. We do not upload it. We do not back it up to our servers. We do not have a copy. If you uninstall SmashKey, you can keep that file or delete it; it's yours either way.
What travels off your device
When you ask SmashKey to fix a piece of text, the text you selected and a small, relevant slice of your input are sent to our server, used to make the correction, and then discarded. We log that the request happened (so we can count fixes against your free or paid quota) but we do not retain the contents of what you typed or what came back.
What we know about you
When you sign in, we create an account with your email address, your tier (free or paid), and a count of how many fixes you've used. That's it. We use your email to send you product-relevant notices (a launch update, a billing receipt if you subscribe). We don't sell it. We don't share it with advertisers.
What we don't do
- We don't accumulate your input on our servers.
- We don't analyse the contents of your typing for patterns to sell.
- We don't share your data with third parties for marketing.
- We don't track you across other websites.
- We don't run ads in the product.
The third parties we do rely on
To make SmashKey work, we route decode requests through a small number of providers. Today that's Anthropic for the language model that does the actual correction work, Cloudflare for hosting, and Clerk for sign-in. Each of these sees only what they need to do their job — the language model sees the text being corrected, Cloudflare sees that a request came through, Clerk sees your sign-in. None of them retain decode contents under our agreement with them.
Changes
If we change how we handle your data, we'll update this page and tell you in the app before the change takes effect. We won't quietly broaden what we collect.
Get in touch
Privacy questions go to support@smashkey.app. We aim to reply within a few working days.
This page is the canonical privacy statement for SmashKey on Windows during private beta. When the product expands to other platforms or adds features that change what data is involved, this page updates first and the change is announced in the app.
