Privacy policy
Last updated October 24, 2026
This policy explains what information Keyin.io (keyin.io) collects, how it's used, and the choices you have. Keyin.io has no accounts, and you never need to give us your name or email address to use it.
What you type
Your typing is processed entirely in your browser. The text you type, your speed and your accuracy are never sent to our servers or anyone else.
Stored in your browser
Keyin.io saves a few preferences in your browser's local storage so they're still there next time: your theme, key sound, practice mode and length, and a count of finished runs used to decide when to show a small support message. This data stays on your device. You can remove it at any time by clearing this site's data in your browser settings.
Analytics
We use Google Analytics to understand how many people visit and which pages they use. Google Analytics sets cookies and collects information such as the pages you visit, how long you stay, your browser and device type, your approximate location (country or city), and the site that referred you. We use this only in aggregate, to improve the site.
We also send Google Analytics a short summary when you start, finish, skip or retry a practice run: which page and mode you practiced in, the book it came from, its length, and for finished runs your speed, accuracy and time. What you type is never sent.
You can learn how Google uses this data at How Google uses information from sites that use its services, and opt out of Google Analytics on every site with the Google Analytics opt-out browser add-on.
Advertising
Keyin.io is free and may show ads served by Google AdSense to cover its costs.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
- You can opt out of personalized advertising in Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.
If you opt out, you'll still see ads, but they won't be based on your browsing. See how Google uses cookies in advertising for details.
Your choices
- Block or delete cookies in your browser settings. The typing practice works without them.
- Use the opt-out links above for Google Analytics and personalized ads.
- If you're in the European Economic Area, the UK or Switzerland, you'll be asked for consent before cookies are used for personalized ads, and you can change your choice at any time.

Keyin.io links to other sites, such as Project Gutenberg, Ko-fi and Google Forms. Their own privacy policies apply once you leave this site.
