Terms of Use

Last updated: October 5, 2026

These are the plain-language terms for using DotSense. By using the tools on this site, you agree to them.

Use the tools freely

You may use DotSense in your classroom, for teaching, tutoring, intervention, and professional learning. You may project the tools, use them with your students, and share the link with other teachers. The free tools don't need an account. DotSense Plus tools need a teacher account and a subscription or an active free trial.

DotSense Plus

DotSense Plus is a yearly subscription that unlocks the Plus tools. It renews each year until you cancel. You can cancel anytime from your account page, and you keep access until the end of the year you've paid for. The 7-day free trial needs no card and doesn't turn into a paid subscription on its own.

Please don't

• Resell the tools or charge others for access to them.
• Copy the site to pass it off as your own product.
• Try to break, overload, or misuse the site.

No warranty

DotSense is provided "as is," without warranties of any kind. We work hard to keep the tools accurate and available, but we can't guarantee they will always be error-free or online. Use your professional judgment when using them with students.

Limitation of liability

To the extent allowed by law, DotSense and its creator are not liable for any damages arising from your use of the tools.

Changes

We may update these terms from time to time; the date at the top shows the latest version.
