Terms of Service — Mastera

Effective: 20 September 2026
Last updated: 20 September 2026

These terms are a contract between you and {{LEGAL_ENTITY}} ("we", "us"), trading as Mastera. They cover the Mastera mobile app, the masteraai.com website, and anything you buy from either.

By using the app you accept these terms. If you don't accept them, don't use the app.

1. Who we are

{{LEGAL_ENTITY}}
{{COMPANY_REG_NUMBER}}
{{REGISTERED_ADDRESS}}
Support: support@masteraai.com

2. Who can use Mastera

You must be at least 13 to use the app.

If you are under 18 (or under the age of majority where you live), you may only use Mastera with a parent or guardian's permission, and only they can buy a subscription. By buying, you confirm you are of legal age to enter a contract.

Mastera is not designed for children and is not directed at under-13s. We don't knowingly collect data from them. See the Privacy Policy.

3. What you get

Mastera is a library of short lessons about AI tools, with quizzes, streaks, progress tracking and completion certificates.

• Free: the first 2 lessons of the first course. That number is set remotely and can change.
• Paid (Mastera Pro): every course and every lesson, including courses we publish later while your subscription is active.

Certificates are a record of what you finished in our app. They are not an accredited or recognised qualification and carry no academic credit.

We may add, change or remove courses and lessons. We may change how the free part works. If we make a change that removes a large part of what you paid for, we'll tell you and you can cancel and ask for a refund of the unused time.

4. Your account

You can use the app without an account.

If you sign in, we use passwordless email sign-in: you enter your email address, we send a link or a code, and that proves it's you. Your email address is your account key. Keep access to that inbox — anyone who controls it can sign in as you. Tell us at support@masteraai.com if you think someone else has access.

5. Plans and prices

*Base price in US dollars. Your store shows your local price including any tax. Prices can differ by country.

Lifetime means for as long as we run the Mastera service — not your lifetime. If we shut the service down, section 13 applies.

6. The 7-day free trial

• The free trial is on the annual plan only.
• It lasts 7 days. On day 8 we charge the annual price unless you cancelled.
• One trial per person, per store. Apple allows one introductory offer per subscription group, ever. Google is similar. If you've already had a trial — including on a different Mastera plan — you'll be charged straight away with no trial. If you upgrade from weekly or monthly to annual, you do not get a trial.
• If you buy a plan while a trial is running, the rest of the trial is lost.
• To avoid being charged, cancel at least 24 hours before the trial ends.

Apple does not email you before a free trial converts. Google Play does. We aim to send our own reminder before the trial ends, but do not rely on it — set your own reminder if you want one.

7. Auto-renewal — read this part

Subscriptions renew automatically. Weekly, monthly and annual plans keep renewing at the then-current price until you cancel.

• Your store charges you within 24 hours before the current period ends.
• Cancelling takes effect at the end of the current period, so you must cancel at least 24 hours before it ends. Cancel later than that and you're charged for the next period.
• Cancelling doesn't refund the period you're in. You keep access until it runs out.
• Deleting the app does not cancel anything. Only cancelling does.

If you can change your price, we'll tell you before it happens — at least 30 days' notice by email or in the app. Where the store requires your agreement to a price rise, your subscription won't renew at the new price until you agree.

8. How to cancel

Bought inside the app on an iPhone or iPad:
Settings → your name → Subscriptions, or
https://apps.apple.com/account/subscriptions

Bought inside the app on Android: Play Store → profile → Payments and subscriptions → Subscriptions, or https://play.google.com/store/account/subscriptions

The app also has a "Manage subscription" link that opens the right page for your device.

Bought on our website: use the cancel link in your purchase confirmation email, or email support@masteraai.com. We'll cancel within one business day and confirm in writing. Californian customers: you can cancel online in the same way you signed up, in as few steps.

9. Refunds

Purchases made inside the app (App Store or Google Play): we cannot refund them, and we cannot see your payment details. Apple and Google are the sellers of record for in-app purchases. Refunds are theirs to give, under their policies:

• Apple: https://reportaproblem.apple.com
• Google Play: https://play.google.com/store/account/orderhistory — or Google's refund help at https://support.google.com/googleplay/answer/2479637

If a store refuses and you think that's wrong, write to us at support@masteraai.com. We'll help where we can, but the decision is theirs.

Purchases made on our website are different. not applicable (we do not sell on this website) processes those payments. For website purchases:

• 14 days, no questions asked. Email support@masteraai.com within 14 days of the charge and we'll refund it in full.
• Renewals: if an annual renewal charge surprises you, email us within 14 days of that charge and we'll refund it, as long as you haven't used the service much since it renewed.
• Refunds go back to the original payment method within 10 business days.
• This is on top of your legal rights in section 10 — it doesn't replace them.

10. If you're in the EU or UK — your right to change your mind

You normally have 14 days to withdraw from a distance contract for digital content or services, with no reason given.

How the digital-content exception works, in plain terms: if you ask for access to start immediately, and you acknowledge that starting immediately means losing the 14-day withdrawal right, then once we've started supplying you, the right is gone. At our web checkout we ask for both of those separately and record your answer. If you don't give them, we wait out the 14 days before opening access.

If the withdrawal right does apply and you use it, we refund what you paid, minus a proportionate amount for the service you already received.

Whatever this section says, our 14-day website refund in section 9 still stands — so in practice, website buyers get their money back either way.

Nothing here reduces your statutory rights, including rights against a non-conforming digital service under Directive (EU) 2019/770 or the UK Consumer Rights Act 2015.

11. If you're in California — automatic renewal terms

For subscriptions bought on our website, under California's Automatic Renewal Law (Bus. & Prof. Code §17600 et seq., as amended by AB 2863):

• Before you pay, we show you, clearly and next to the buy button: that it's an automatic renewal, how often it renews, the amount, how to cancel, and the deadline to cancel.
• We only start a subscription after you tick or tap something that's about the auto-renewal terms specifically — not bundled into a general "I agree".
• We email you an acknowledgement with the auto-renewal terms, the cancellation policy and how to cancel, in a form you can keep.
• For the annual plan, we email you a renewal reminder between 45 and 15 days before it renews, with the renewal date, the amount, and a cancel link.
• You can cancel online, immediately, in the same way you signed up — no phone call, no retention call, no more clicks than it took to subscribe.
• If we change the terms materially, we tell you first and you can cancel.

In-app purchases through Apple or Google are billed and cancelled through those stores, which run their own auto-renewal disclosures.

12. What you may and may not do with the content

We give you a personal, non-exclusive, non-transferable, revocable licence to view and use the lessons, prompts, images and exercises inside the app, for your own learning — including at work, for your own work.

You may not:

• copy, republish, post, sell, licence, or share the lesson text, prompt library, images or course structure, in whole or in substantial part, anywhere outside the app;
• scrape, bulk-download, mirror, or feed our content into a dataset or a model, by hand or with software;
• resell access, share your account, or run the content as your own course, training, workshop or newsletter;
• remove credits or notices, reverse-engineer the app, or work around the paywall, rate limits or any technical restriction;
• use the app to break the law, harass anyone, or attack our systems.

Everything in Mastera — the courses, the writing, the illustrations, the name and the design — is ours or licensed to us. Nothing here transfers ownership.

Third-party names (ChatGPT, Claude, Gemini, Midjourney and others) belong to their owners. We use them to describe the tools we teach. We are not affiliated with, endorsed by, or partnered with any of them.

13. Things you give us

If you write a survey response, a note or any other text into the app, you keep it. You give us permission to store it and use it to run and improve Mastera. Don't put anything confidential or anyone else's personal data into those fields.

14. What we don't promise

Mastera teaches you to use third-party AI tools. Those tools change without telling us. A screenshot, a menu name, a model or a price in a lesson can be out of date by the time you read it. We update the courses, but we cannot guarantee that every instruction matches the tool in front of you today.

• The lessons are education, not professional advice. Nothing here is legal, financial, medical, or employment advice.
• AI tools make mistakes and invent facts. Check anything that matters.
• We don't promise a job, a promotion, income, or any particular outcome.
• The app is provided "as is" and "as available". We don't promise it will be uninterrupted or error-free.

15. Liability

To the extent the law allows:

• We're not liable for lost profits, lost data, lost opportunities, or indirect or consequential loss.
• Where we are liable, our total liability to you is limited to what you paid us in the 12 months before the claim, or the total amount you paid us in the twelve months before the claim if you paid us nothing.

None of this limits liability we can't limit by law — including death or personal injury caused by our negligence, fraud, or your non-excludable consumer rights. If you're a consumer in the EU or UK, your statutory rights come first.

16. Suspension and ending this agreement

You can stop at any time — cancel your subscription (section 8) and delete the app.

We can suspend or close your account if you break these terms, in particular section 12. If we close your account for something you did, you don't get a refund for the rest of the period. If we close it for any other reason, we refund the unused time.

If we discontinue Mastera entirely, we'll give at least 30 days' notice and refund the unused part of any subscription. For Lifetime purchases made within the previous 12 months, we'll refund on a pro-rata basis over 24 months from purchase.

17. Changes to these terms

We can update these terms. If a change matters — price, renewal, your rights — we'll tell you at least 30 days before it takes effect, in the app or by email, and you can cancel before it applies. Small corrections take effect when posted. The "Last updated" date at the top always tells you which version you're on.

18. Apple-specific terms

These apply if you got the app from Apple's App Store.

• This contract is between you and us, not Apple. Apple is not responsible for the app or its content.
• Apple has no obligation to provide any support or maintenance for the app.
• If the app fails to conform to any warranty, you can tell Apple and Apple will refund the purchase price of the app (if any). Beyond that refund, Apple has no warranty obligation at all, and any other claims are our responsibility.
• We, not Apple, are responsible for handling any claim that the app or your use of it infringes intellectual property rights, and for any product liability claim or claim that the app fails to meet a legal requirement.
• You confirm you are not in a country subject to a US embargo or designated a "terrorist supporting" country, and you are not on any US list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

Purchases made through Google Play are also subject to the Google Play Terms of Service.

19. Law and disputes

These terms are governed by the laws of the laws of Israel, and disputes go to the courts of the competent courts of Tel Aviv-Jaffa, Israel.

If you're a consumer, this doesn't take away the protection of the mandatory laws of the country you live in, and you can always bring a claim in your own country's courts.

Before filing anything, please email support@masteraai.com. Most things are faster to fix that way.

EU residents can also use the European Commission's online dispute resolution platform.

20. The rest

• Whole agreement. These terms plus the Privacy Policy are the whole agreement between us about Mastera.
• If part of this fails, the rest still stands.
• No waiver. If we don't enforce something straight away, we haven't given it up.
• Transfer. You can't transfer your rights under these terms. We can transfer ours if our business is sold, as long as your rights aren't reduced.
