Terms of Use
Last updated: 4/29/2026
Use of the service
Key Warrior is provided free of charge for personal, non-commercial use. No account is required — you can start typing immediately. Don't use the service in ways that interfere with other users, attempt to attack or scrape the service, or violate applicable laws.
Local data on shared devices
All progress (XP, level, streaks, personal bests, achievements) is stored in your browser's localStorage on the device and browser profile you used. If you practice on a shared or public device, you are responsible for clearing your local data when you're done — the simplest way is to clear site data for keywarrior.productivities.net in your browser settings, or use private/incognito mode.
Advertising
Key Warrior is part of the Productivities.net network, which uses Google AdSense to cover hosting costs. By using the service you acknowledge that ads may be displayed and that AdSense's terms and Google's broader advertising policies apply. See the parent network's privacy policy for the full disclosure.
No warranty
The service is provided "as is" without warranties of any kind. We make no guarantees about uptime, accuracy of metrics, or fitness for any particular purpose.
Limitation of liability
To the fullest extent permitted by law, Key Warrior and its operators are not liable for any damages arising from use or inability to use the service.
Changes
We may update these terms from time to time. Continued use after changes means you accept the updated terms.
