Learners turn, run and break real-time simulations in the browser instead of only reading. The first world of every lab is free; PRO unlocks every lesson for $39.99 a month, $99.99 a year, $149.99 a year for a family or $299.99 once. There is no free trial and nothing to install. - **Is Novareka free to use?** Yes. The first world of every lab is free forever, with no account and no card. PRO unlocks every lesson, simulation and practice exam in every lab, including labs added later. - **How much does Novareka PRO cost?** PRO costs $39.99 per month, $99.99 per year, or $299.99 once for lifetime access. The Family plan is $149.99 per year: everything in PRO for one parent and up to four kid profiles, plus a weekly progress email (Lifetime includes the same; other plans keep one kid profile). There is no free trial: you can try the free world of every lab before you pay. - **Which subjects do the 26 labs cover?** Physics (forces, waves, optics, electric and magnetic fields, quantum), chemistry, crystals and organic chemistry, genetics and the human body, astronomy and orbits, weather and plate tectonics, calculus, geometry, vectors and probability, electronics with Arduino, logic gates and robotics, cryptography, music theory and machine learning. - **What ages is Novareka for?** Lessons run from first steps to high-school, AP, IB and early university level.

Progress is kept in your browser, and signing in (Google or an e-mail link) keeps it on every device. - **How are lessons checked?** Each lesson asks you to do something in the simulation, such as reach a target orbit or balance a reaction, and to answer short quiz questions. A lesson only counts as complete when the real goal in the simulation is met, not just when you read it. - **Can teachers use Novareka in class?** Yes. Teachers can use the classroom tools and embeddable labs for free. The Teacher plan ($249.99 a year) adds class tracking and assignments for 40 students; the School plan ($1,499 a year) covers unlimited teachers and up to 500 students, is bought online like every plan, and whoever buys it becomes the school admin. Questions: coddy@coddykit.com. Simulations are teaching models, simplified on purpose, and say so on every page. - **How do I cancel or get a refund?** Payments are handled by Paddle, our merchant of record. You can cancel any time from the Paddle customer portal and keep PRO until the end of the period you paid for. Refunds can be requested within 24 hours of a payment; see the refund policy. ## Policies - [Terms](https://novareka.com/terms) · [Privacy](https://novareka.com/privacy) · [Refund policy](https://novareka.com/refund-policy) · [Kids privacy](https://novareka.com/kids/privacy) · [Contact](https://novareka.com/contact)
