Terms of Use
Updated November 5, 2026
Dose Drill helps nursing and allied health students practice the math, one question at a time. These terms explain how the service and its plans work.
The service is operated by Dab Hands Tub & Tile Reglazing, LLC under the Dose Drill name. Please review these terms and our Privacy Policy when using your account or purchasing access.
Free account and Full Pass
- Free calculators: the standalone study calculators are available without a paid plan or an account.
- Free practice: an account includes 10 practice questions total, shared across dosage practice and community sets. The allowance follows your account across devices and does not reset each day.
- Full Pass: $29 USD, paid once, for lifetime Full Pass access on your account. It includes unlimited dosage practice, community sets, saved progress and missed-question retries. It is not a recurring subscription.
- Community sets: a separate limit of 20 new community sets per UTC day applies, including for Full Pass accounts.
Checkout displays the amount due before you pay. Sign in with the account used for your purchase to restore access. If access does not appear, use Refresh access on the Account page or contact support.
Educational use
Questions, examples, explanations and calculators are study aids. They are not medical advice, clinical guidance, medication orders or a substitute for professional judgment. Always follow your school’s or institution’s instructions, use authoritative references and verify any clinical calculation independently before patient care.
Practice results, badges and study-circle ranks are not professional certifications. We do not promise a particular exam result or clinical outcome. If you find an error, please report the tool, inputs and result to support without including patient information.
Your account and participation
Keep your password private and use accurate account information. Full Pass belongs to the purchasing account. Do not resell access, share an account publicly, bypass usage limits, interfere with the service or attempt to access another person’s information.
Use a respectful study-circle nickname and do not impersonate another person or include private information in it. You choose whether your study-circle profile is visible. We may restrict activity that abuses the service or compromises other learners’ accounts or safety.
Payments and refunds
Stripe processes payments. Refund requests are reviewed individually as described in our Refund Policy. Contact us about duplicate charges, payment errors or paid-access problems. Nothing in these terms removes consumer rights that cannot be excluded under applicable law.
Service and content
The site and study features may be updated to fix errors, improve usability or maintain the service. Maintenance and service interruptions can occur. Contact support if a problem prevents you from using access you purchased.
Dose Drill branding, illustrations, interface and original content are provided for your personal study. Third-party materials and references remain subject to their owners’ rights.
