Terms of service

Last updated 5 November 2026

Who we are

Dray is a study app for Mac, iPad and iPhone, with the Dray Visualize website at usedray.com. It's made by Probe Network Inc., of Surrey, British Columbia, Canada; "Dray", "we" and "us" mean us. Questions go to [email protected].

By creating an account or using Dray you agree to these terms and to our privacy policy.

Your account

• You sign in with your email address. Keep access to that email safe, because anyone who can read it can sign in as you.
• Give your real age group and country. Some features and all purchases depend on them.
• If you're under 13, Dray's AI features stay off. If you're 13 to 17, they're off for now; when they come on, you'll need a parent's or guardian's permission. Only people 18 or older can buy anything.
• One account per person. Don't share it or sell it.

Credits and prices

• Videos, audio and transcripts use credits. Before anything starts, Dray shows the exact number of credits it will use, and nothing is spent until you confirm.
• When you start, the credits are held. They are spent when the result is ready. If it fails, they come back.
• Credits you buy never expire. Credits that come with a plan last until the end of that billing period. Credits have no cash value, can't be exchanged for money, and can't be moved to another account except through Dray's own sharing features.
• New accounts may get free credits once. We may change or end free offers, but credits already in your account stay.
• Prices are shown in your local currency where we can, with taxes shown at checkout.

Payments, subscriptions and refunds

• Payments on the web are handled by Stripe. Purchases in the iPhone and iPad apps are handled by Apple under its own terms.
• Dray Pro and Dray Max renew at the end of each period you chose (a month, six months or a year) until you cancel. You can cancel at any time; your plan stays on until the end of the period you paid for.
• Dray Max includes movies without credits, within the fair-use limits shown on the pricing page and in the app before you buy. Limits you bought under stay as they were until you change plan.
• If you got Dray from the App Store, Apple's standard licence agreement applies too, and Apple handles your subscription, renewals and refunds.
• If something went wrong with a purchase, write to [email protected] and tell us what happened. If we refund a credit pack, the unspent credits from that pack are removed.
• Nothing here takes away rights you have under consumer law where you live.

Your content

• You keep ownership of what you upload, paste or record, and of the videos, audio and transcripts Dray makes from it.
• You let us store and process your content only to run Dray for you: to make what you ask for, keep it in your library and show it to people you share it with.
• Only upload material you have the right to use. If you share a video, you're responsible for what it shows.
• If someone believes content on Dray infringes their rights, they can write to us and we'll look into it.

Movies offered to classmates

When you make a movie of part of a reading, Dray may offer it, without your name, to classmates who have the same reading or ask about the same idea. When they watch it instead of making their own, you earn back a tenth of what you paid each time, up to all of it, as credits that last a year. Turn off Offer to classmates on a movie's page to stop offering it.

Seats from a school or organisation

If your school or another organisation gives you a seat, it pays for the movies you make with it, and its report shows who made each one, its title, its length and the credits it used. What you make stays in your own library.

AI answers and videos

Dray uses AI models to explain, draw and narrate. They can make mistakes, even after Dray checks them against your text. Treat what Dray makes as a study aid, not as professional, medical, legal or financial advice, and check anything important against your sources.

Connecting ChatGPT, Claude and other assistants

When you connect an assistant to Dray, you let it see your credit balance and videos and make videos with your credits, within the permissions you approved. The assistant's own terms apply to the assistant. You can disconnect by removing Dray in that assistant's settings.

Things you can't do

• Break the law, or help someone else break it.
• Upload material that harms, harasses or sexualises anyone, or that you aren't allowed to share.
• Try to get around prices, limits or security, or access other people's accounts or data.
• Copy, scrape or resell Dray itself, or use it to build a competing service.
• Overload Dray with automated requests beyond normal use.

If things go wrong

• We may suspend or close an account that breaks these terms.
• We work hard to keep Dray running, but we can't promise it will always be available or free of errors.
• To the extent the law allows, Dray is provided as it is, and our total responsibility to you is limited to what you paid us in the 12 months before the problem.

The law that applies

These terms are governed by the laws of British Columbia and of Canada that apply there. Nothing here takes away rights you have under the consumer law where you live, or your right to go to the courts there.

Changes

If we change these terms in a way that matters, we'll update the date at the top and tell you in the app or by email before the change applies. If you keep using Dray after that, the new terms apply.
