Store / Policies

Last updated date of launch

The small print, in plain words.

Calcade modules are made and tested by hand by Ethan Paschkes. Orders are taken through a checkout run by checkout service, on an account held by a parent.

Refunds and swaps

30 days, no fuss. If you're not happy, tell us within 30 days of delivery and send the module back with what came in the box. You choose: your money back, or a swap for a different model (you pay or get back the price difference).

  • If it arrived faulty or stops working within the 30 days, we pay the return shipping and send a working one or refund you.
  • Otherwise, return shipping is on you / on us.
  • Refunds go back to the card or account you paid with, within a few days of the module arriving back.
  • The AI plan, if you have one, can be stopped anytime; the month already started isn't refunded.

Shipping

  • USA only for now.
  • Every unit is tested on a real calculator before it ships, so it ships when built and tested. Waitlist invites go out only for units that are ready.
  • Shipping costs free / price at checkout. You get a tracking number by email.
  • The launch models have no battery inside; they run on the calculator's power.
  • If a parcel is lost or arrives damaged, tell us and we'll sort it out.

Privacy

The short version: we keep as little as possible, and we never sell anything.

  • Waitlist. Your email, and the model you picked, are kept with our email-list service only to send invites and store news. Every email has an unsubscribe link. You need to be 13 or older, or have a parent sign up.
  • Orders. Your name, email and shipping address go to the checkout service and to us, only to ship your order and handle refunds. Card details are handled by the checkout service; we never see them.
  • AI questions and photos. They go from your module to our server and on to the AI service that writes the answer, and we don't store them. The server keeps only a count of how many questions each unit has asked, to apply the included allowance. The AI service may keep requests for a short time for its own safety checks, under its own policy.
  • Games and web. These stream from your own computer at home to your calculator; we don't see them.
  • The try-it calculator. Questions typed into the live demo are answered and not stored. Your browser remembers how many demo questions you've used today.
  • These store pages have no ads and no tracking cookies.

Want your data deleted? Ask us (see Contact) and we'll remove it.

Your calculator

  • The modules work with the TI-84 Plus CE (including the CE Python). The calculator is not included.
  • Nothing is opened or soldered. The calculator apps run on top of the calculator's normal software; you install them once with TI's free TI Connect CE, following the guide.
  • Not for tests or exams. Take the module off before any test, like any other gadget, and follow your school's rules.
  • Not affiliated with Texas Instruments, Epic Games or OpenAI. TI-84 Plus CE is a trademark of Texas Instruments.
