Terms of Service

You must be at least 13 years old to use Lykke, or older if the law where you live sets a higher minimum age. Lykke isn’t meant for children under 13, and we don’t knowingly let them have accounts. If we learn that a child under 13 has an account, we’ll close it and delete their information. If you think that has happened, tell us at hello@getlykke.com.

If you’re under 18, or under the age of majority where you live, you may use Lykke only with the permission of a parent or legal guardian, who must agree to these Terms on your behalf. A parent or guardian must also make or approve any purchase, like a subscription, credits or a course, and is responsible for it.

If you let your child use Lykke, you agree to these Terms on their behalf, and you’re responsible for their use of the Service and for any purchases made from their account.

You can’t use Lykke where the law doesn’t allow it, or if we’ve previously closed your account for breaking these Terms.

We keep improving Lykke, so we may add, change or remove features. Features labeled beta or preview, like the Video Tutor, may be less reliable, and may change or end. If we make a change that significantly reduces what a paid plan includes, we’ll tell you before it takes effect, and you can cancel and get a refund for the unused part of your billing period.

Give us accurate information and keep it up to date. Each account is for one person: don’t share your sign-in or let anyone else use your account. You’re responsible for keeping your sign-in secure and for what happens under your account. If you think someone else has got into it, tell us right away at hello@getlykke.com.

You may connect your Canvas account and other services to bring in your materials. You confirm that you’re allowed to access those accounts, and that syncing or uploading the materials follows your school’s policies and copyright law. We never store your Canvas password.

You can stop using Lykke at any time. To delete your account, choose Delete Account in Settings, or email hello@getlykke.com from the address on your account. Deleting it also ends any Luminary subscription, without a refund for the rest of the current period, and any credits left in the account are lost. Courses you’ve published or shared with others may stay available to them unless you ask us to remove those too. We keep only what we must, such as payment records; the Privacy Policy explains the rest.

Explore (without an account) and Scholar are free. Luminary is a paid subscription. What each plan includes, and the current prices, are on our Pricing page. We may change what the free plans include.

You pay the price shown when you subscribe or buy. Prices are in US dollars. Where we’re required to collect sales tax, VAT or a similar tax, we add it at checkout. Your bank may charge its own fees, for example for currency conversion.

Payments are processed by our payment provider, Stripe; we never see or store your full card number. When you subscribe or buy something, you authorize us, through Stripe, to charge your payment method for it, and for each renewal as described in Section 5. Keep your payment details up to date. You subscribe and buy credits on getlykke.com, not in the iOS app.

If you switch between monthly and yearly billing, we’ll tell you the new price and when you’ll be charged before the change takes effect.

We may change Luminary’s price. If the price of your subscription goes up, we’ll email you about 30 days before your first renewal at the new price, and you can cancel before then. A price change never applies to a period you’ve already paid for. If you’re charged the higher price and didn’t mean to continue, cancel within 14 days of that charge and we’ll refund the part of the period you haven’t used.

If a payment fails, Stripe may try it again, and your subscription may be marked past due in the meantime. If the payment can’t be collected, Luminary ends and your account moves to Scholar.

New accounts may get a free Luminary trial, currently 7 days long. The trial needs no payment details, so it never turns into a paid subscription on its own: when it ends, your account moves to Scholar, you aren’t charged, and everything you made stays yours.

The trial includes most of Luminary. What it leaves out is listed on our Pricing page: currently the Video Tutor, the Video Skimmer, Luminary’s monthly credits (you use your launch credits instead) and more than 3 new course builds.

If you subscribe during your trial, billing starts that day, and the days left in your trial aren’t added on.

Trials are one per person. We may change or stop offering trials, and we may end a trial obtained by creating extra accounts or other abuse.

Because you can cancel at any time and keep Luminary until the end of the period you’ve paid for, payments are non-refundable: we don’t refund or credit partial billing periods, unused time or unused credits, except in the cases below or where the law requires it.

• Billing mistakes. If you were charged twice, charged after you cancelled, charged without your permission or charged the wrong amount, tell us within 60 days and we’ll refund the mistaken charge.
• A yearly renewal you meant to cancel. If your yearly plan renews and you tell us within 14 days of the renewal charge, we’ll cancel it and refund that charge, as long as you haven’t used Luminary’s paid features since it renewed.
• Your right to withdraw in the EU and UK. If you live in the European Union or the United Kingdom, you may withdraw from a new subscription within 14 days of buying it by telling us. We’ll refund your payment, less a proportionate amount for the days you had Luminary before you withdrew.

Refunds after a price increase are covered in Section 5, and refunds for paid courses in Section 9. To ask for a refund, email hello@getlykke.com from the address on your account. We process approved refunds within 14 days, back to the payment method you paid with.

Credits pay for the AI work in Lykke, like chat, making study materials and the Video Tutor. How many credits a feature uses is shown in the app or on our Pricing page. We may change what features cost in credits, and we’ll tell you in the app before a change that makes something cost more.

Luminary comes with a monthly allowance of credits (currently 20,000), on yearly plans as well as monthly ones. Plan credits you don’t use carry forward for up to 3 months, or 6 months on a yearly plan, and then expire. Credits carried forward are used first.

Credits you buy as a top-up never expire while your account is open, and you keep them if your paid plan ends. They’re used after your plan credits.

Credits we give you for free, like launch, referral or promotional credits, may come with their own conditions or expiry dates. On Luminary they’re used and carried forward like plan credits, and they end if your paid plan ends.

Credits have no cash value. You can’t sell them, move them to another account or exchange them for money, and they aren’t refundable except where the law requires. Credits left in an account are lost when the account is deleted or closed.

If something fails because of a problem on our side, we may return the credits it used. We may also correct a balance that’s wrong because of an error.

Some courses on Lykke are made by other users (“creators”), who can charge for access. If you buy access through Lykke’s checkout, you see the price before you pay, Stripe processes the payment, and you get personal access to the course from your account for as long as it’s available on Lykke. Creators may update their courses.

If you ask within 14 days of buying a course through Lykke’s checkout, we’ll refund you, unless you’ve already worked through most of it or we see a pattern of refund abuse. If the course is removed from Lykke within 30 days of your purchase, we’ll refund you too.

A creator may link to their own payment page instead. That purchase is between you and the creator, under their terms: Lykke isn’t part of it and can’t refund it.

If you charge for a course, you confirm that you own it or have every right needed to sell it, that it doesn’t infringe anyone else’s rights, and that its description is accurate. You’re responsible for its content and for any taxes on what you earn. To be paid for sales made through Lykke’s checkout, you first need to agree separate creator terms with us, which set out payouts and fees: contact us at hello@getlykke.com before you turn on paid access. We may remove paid access, or a course, that breaks these Terms.

A coupon or discount applies only as its offer says, for example to your first billing period, and after that your subscription renews at the regular price. Unless the offer says otherwise, coupons are one per account, can’t be combined, have no cash value and may expire.

When someone joins Lykke with your referral code, you and they each get referral credits, as described in the app. Don’t refer yourself, create accounts to earn referrals, or send invitations to people who wouldn’t want them. We may withhold or remove referral credits earned that way.

Any giveaway, contest or raffle we run is governed by its official rules, published with it. Where those rules differ from these Terms, the rules apply.

The Service — including its source code, interfaces, databases, functionality, website designs, text, photographs, and graphics (“Content”) and the trademarks, service marks, and logos (“Marks”) — is owned or controlled by us or licensed to us, and is protected by copyright and trademark laws. Courses and other content made by other users belong to them.

We give you a personal, non-exclusive, non-transferable license to use the Service as these Terms allow. It ends if your account is closed.

We respect copyright and expect you to. If you believe content on Lykke infringes your copyright, email hello@getlykke.com with: (1) the copyrighted work; (2) the content you say infringes it and where it is on Lykke, such as a link; (3) your name, postal address, phone number and email; (4) a statement that you believe in good faith that the use isn’t authorized by the owner, its agent or the law; (5) a statement, under penalty of perjury, that your notice is accurate and that you are the owner or authorized to act for the owner; and (6) your physical or electronic signature.

We may remove or disable the content and will tell the person who posted it. If your content was removed and you believe that was a mistake, you can send us a counter-notice. We close the accounts of people who repeatedly infringe copyright.

The Service depends on third-party providers, including cloud hosting, databases, AI model providers and Stripe for payments (see the Privacy Policy for the current list). Your use of features powered by those providers is also subject to their terms. We are not responsible for outages or policy changes on those providers, though we will work to minimize user impact.

If you connect Lykke to another AI app, for example through our MCP server, that app gets the access you approve, and its own terms and privacy policy govern what it does with it. You can disconnect it at any time in Settings.

If you use our iOS app, these Terms are between you and Lykke, not Apple. Apple isn’t responsible for the app or its content, has no obligation to maintain or support it, and isn’t responsible for any claims about it, including product liability, legal or regulatory compliance, consumer protection or intellectual property claims. You must also follow the App Store’s terms. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you as they relate to the iOS app.

You can stop using Lykke at any time, and delete your account as described in Section 3.

We may suspend or close your account, or limit what you can do, if you seriously or repeatedly break these Terms, if the law requires it, or to protect people, the Service or others from harm or fraud. Where we reasonably can, we’ll tell you why beforehand and give you a chance to fix the problem. If we close your account because you broke these Terms, you won’t get a refund.

If we close your account for any other reason, or stop offering Luminary or the Service, we’ll give you reasonable notice where we can and refund any prepaid subscription fees for the unused part of your billing period.

When your account ends, so does your right to use the Service. You can ask us for a copy of your data first, as described in the Privacy Policy. Parts of these Terms that by their nature should last, such as the licenses for content you shared, the disclaimers, the limitation of liability and how disputes are resolved, continue to apply.

To the extent the law allows, you’ll compensate us for claims made against us by others, and for the related losses and reasonable legal costs, that arise from Your Content or your breach of these Terms, except where the claim is caused by our own fault.

If you have a problem with Lykke, please contact us first at hello@getlykke.com: most problems can be sorted out quickly. Before starting a formal legal claim, you and we each agree to try to resolve the dispute informally for at least 30 days after one of us sends the other a written description of it.

We may update these Terms. We’ll change the “Last Updated” date above, and if a change is material, we’ll tell you by email or in the app at least 30 days before it takes effect, unless the change is required by law or only concerns new features. Changes don’t apply to disputes that arose before them. If you keep using the Service after a change takes effect, the updated Terms apply to you; if you don’t agree, stop using the Service and cancel any subscription before then.

These Terms, together with our Privacy Policy and any terms shown with a particular offer, are the whole agreement between you and us about the Service. If a court finds part of them unenforceable, the rest still applies. If we don’t enforce part of them straight away, we haven’t given up the right to. You can’t transfer these Terms to anyone else; we may transfer them as part of a merger, acquisition or sale of assets, and we’ll tell you if we do. We aren’t responsible for delays or failures caused by events outside our reasonable control. If we provide a translation of these Terms, the English version controls.
