Terms of Service

The agreement every policy is part of: how you accept it, what ACADA is and is not, buying and earning, no warranty, the limits of our liability, individual arbitration with an opt-out, and how changes are announced and accepted.

Last updated on October 25, 2026.

These are the terms between you and ACADA L.L.C. for using acada.ac. You accept them by creating an account or using the site, and they include every other ACADA policy: the specific policies own their subjects and their numbers, and this agreement holds what is left, which is the legal machinery. ACADA is a marketplace and a community; instructors are independent, nobody reviews their courses, and a course is what its instructor makes it. What you post stays yours. Prices are in US dollars and refunds follow the Purchases policy. We provide the site as it is, our liability to you is capped, and a dispute between us goes first to sixty days of talking, then to individual arbitration, with an opt-out you can send within thirty days. A change that adds a rule or a cost is announced fourteen days ahead, and you accept it before it applies to you.

This summary is for orientation only. The sections below are the operative terms.

1. This agreement, and how you accept it

This agreement is between you and ACADA L.L.C., a Tennessee limited liability company (ACADA, we). It covers acada.ac, its apps and emails, and everything you do through them. You accept it by creating an account, and by using the site whether or not you have one. We record when you accepted and which version.

The other policies are part of it. Every policy published at acada.ac/policies is incorporated into this agreement and binds you as this agreement does: the Privacy Policy and Cookie Policy; the Community Guidelines, Acceptable Use Policy and Prohibited Content; Account & Identity and Age & Child Safety; Purchases, Refunds & Subscriptions, the Course Content Policy, Academic Integrity, Reviews & Ratings and the Educational Disclaimer; Intellectual Property, Copyright & DMCA and Trademark; Fraud & Scams and Account Enforcement & Appeals; the AI Content Policy, Credential Policy and Verification Policy; and Accessibility. An instructor, collaborator or affiliate also accepts the Instructor Agreement, Collaborator Terms or Affiliate Agreement when they take that role, with the payout and marketing policies each names.

When two documents differ. On its own subject, the specific policy governs: a refund window, a commission rate, a retention period or an enforcement step is what that policy says, and this agreement does not change it. On everything else, this agreement governs.

If you are under 18. You may use ACADA from 13, as Age & Child Safety sets out. Your parent or guardian is responsible for your use of ACADA and for what you buy, and agrees to this agreement on your behalf; a purchase made without their permission is handled under section 5 of that policy.

2. Words used here

  • The site is acada.ac and everything we run under that name. Member is anyone with an account. Student is a member in a course; instructor, collaborator and affiliate are members in those roles under their agreements.
  • Course is anything an instructor publishes for students: its lessons, files, quizzes, room and certificate. Content is anything anyone puts on the site.
  • Policies are the documents in section 1. Business day is a weekday, Monday to Friday, wherever you are.

3. Your account

One account, in your own name or a name you are genuinely known by, with a real date of birth and a working email address, as Account & Identity sets out. Keep your password to yourself and turn on two-factor authentication if you can; what happens through your account is your responsibility until you tell us it has been taken over, and then it is ours to help you recover. You can close your account at any time in Settings, and section 10 says what follows.

4. What ACADA is, and is not

ACADA is a place where people publish courses and other people take them, with rooms, portfolios, certificates and a marketplace around them. Instructors are independent: not our employees, agents or partners. We do not review a course before it is published, we do not verify an instructor's qualifications, and a course is what its instructor makes it. The Educational Disclaimer says what that means for what you learn; the Credential Policy says what a certificate is; the Verification Policy says what "verified" means. The ACADA Assistant is an AI, provided as it is, under the limits in the Acceptable Use Policy and the AI Content Policy.

5. Using ACADA

We give you a personal, non-exclusive, revocable licence to use the site as it is built to be used, for as long as this agreement lasts. The Acceptable Use Policy says how the site may and may not be used; the Community Guidelines say how to treat people; Prohibited Content says what may never be posted; the Course Content Policy and Academic Integrity say what a course and a student's work must be. Those policies are the rules, and this licence ends where they do.

6. Content and intellectual property

What you post stays yours, and you give us the licence the Intellectual Property policy describes, which is the licence it takes to run the site. What we made is ours: the site, its design, its text and its marks, which the Trademark policy governs. You promise that what you post is yours to post and breaks no law and no policy. A claim that content on ACADA copies someone's work goes through Copyright & DMCA, and repeat infringers lose their accounts as that policy says.

7. Buying

Prices are set by instructors, in US dollars, and the price shown at checkout is the price you pay, plus any tax the law requires us to collect, which is shown before you pay; any other tax on your purchase is yours. Payment is taken by Stripe or PayPal under their own terms. Monthly access renews until you cancel; lifetime access is one payment for the life of the course; refunds, trials, discounts and what happens when a course closes are in Purchases, Refunds & Subscriptions, which is the whole of what we promise about money you pay us. A chargeback on a completed or refunded purchase is fraud under Fraud & Scams.

8. Earning

An instructor, collaborator or affiliate earns under their agreement and its payout policy, and nothing here changes a figure in those. People we pay are independent contractors, not employees, and are responsible for their own taxes; Stripe and PayPal issue the tax forms and hold the identity and bank details a payout needs, under their own terms.

9. Enforcement

We may remove content, unlist or pause a course, restrict an account, or close a role or an account, for the reasons and by the steps in Account Enforcement & Appeals, and every decision taken against you can be appealed under it. A person makes each of those decisions. Where the law requires us to act, we act as the law requires.

10. Ending this agreement

  • By you. Close your account in Settings. Account & Identity says what is deleted and when, and Purchases says what happens to paid access. An instructor's courses close on the terms of the Instructor Agreement.
  • By us. By closing your account under Account Enforcement & Appeals, or, if we shut ACADA down, with at least 60 days' notice as Purchases sets out.
  • What survives. Sections 6, 11, 12, 13, 14, 15 and 17; the licences each policy says continue after it ends; money either side still owes the other; and the records each policy says we keep.

11. No warranty

ACADA is provided as it is and as available. We do not promise that the site will be uninterrupted, error-free or secure, that a course is accurate, complete or fit for a purpose, that you will learn anything, pass anything or earn anything, or that an instructor, a certificate or a mark means more than the policies say. We may change, suspend or retire a feature, and we tell you when it affects something you paid for. Services other companies provide, such as payments through Stripe or PayPal, are under their terms, and we are not responsible for them. To the fullest extent the law allows, we disclaim every warranty not stated in this agreement or a policy, including implied warranties of merchantability, fitness for a purpose and non-infringement.

12. The limits of our liability

To the fullest extent the law allows, ACADA, its members, officers and people who work for it are not liable to you for indirect, incidental, special, consequential or punitive damages, lost profits, lost data or lost goodwill, however they arise, even if we were told they might. Our total liability to you for everything arising out of this agreement, the policies or the site, in contract, tort or otherwise, is limited to the greater of the amounts you paid ACADA in the 12 months before the claim arose, or 100 US dollars.

These limits do not apply to liability that cannot be limited by law: our fraud or gross negligence, death or personal injury caused by our negligence, and rights a consumer law where you live gives you that cannot be waived. Nothing in this agreement takes such a right away.

13. Your responsibility to us

If someone brings a claim against ACADA because of your content, your conduct on or off the site, or your breach of this agreement or a policy, you cover what it costs us to deal with it, including reasonable legal costs, and you help us handle it; we tell you promptly and do not settle it on your behalf without your agreement. The Instructor, Collaborator and Affiliate agreements say the same for their roles.

14. Governing law

This agreement does not choose a state's law: a dispute is decided under the law that applies to it, and the arbitration in section 15 is governed by the Federal Arbitration Act. A claim that reaches a court under section 15 is brought in a court that has jurisdiction over it. If you live in the European Union, the United Kingdom or another place whose consumer law gives you the right to sue at home under your own law, that right is not affected by this section.

15. Resolving disputes

  • First, talk. Before either of us starts a case, we write to the other with what happened and what would fix it: you to support@acada.ac with "Legal notice" in the subject, we to the email on your account. We then have 60 days to sort it out. Most things are.
  • Then, arbitration. A dispute that talking does not resolve is decided by binding individual arbitration under the Consumer Arbitration Rules of the American Arbitration Association, by one arbitrator, by video or written submissions, or in person if you and the arbitrator prefer. We pay the fees those rules put on the business. The arbitrator applies this agreement and the law that applies to the dispute, can award whatever a court could to you alone, and their decision can be entered in any court.
  • Small claims stay open. Either of us may bring a claim that qualifies in a small-claims court instead.
  • Individually. You and we bring claims only in our own names, not as a plaintiff or member of a class, consolidated or representative action, and the arbitrator cannot combine claims of different people. If this sentence is found unenforceable for a claim, that claim goes to the courts in section 14, and the rest of this section stands.
  • Many alike. If 25 or more members bring the same kind of claim with the same lawyers within 90 days, they are heard in batches of up to 25, with the fees for each batch paid when it starts, and the results of the first batches used to settle the rest.
  • Opt out. You can reject arbitration by emailing support@acada.ac within 30 days of first accepting this agreement, with "Arbitration opt-out" in the subject and your account email; then section 14's courts decide, and the other parts of this section still apply.
  • No jury. For anything that does reach a court, you and we give up a trial by jury, as far as the law allows.
  • One year. A claim must be started within one year of when it arose, where the law allows that limit.
  • Where the law says otherwise. If you live where mandatory law does not allow arbitration of consumer disputes or a class waiver, this section applies only as far as that law allows, and your local courts and rights stay yours.

16. Changes to this agreement

When we change this agreement or a policy, we change the date shown at the top. A correction or a clarification takes effect when it is posted. A change that adds a rule, a consequence or a cost, changes what you are paid, changes a licence, or changes this section, section 12 or section 15, is announced in the app and by email at least 14 days before it takes effect, with what changed in a sentence. From the day it takes effect, you are asked to read the new version and accept it before you go on using ACADA; we record your acceptance. If you do not accept, you can close your account, and what you paid for follows Purchases. A change does not apply to a purchase already made, a course already closing, or a dispute already started.

17. General terms

  • The whole agreement. This agreement and the policies are the whole agreement between you and us about ACADA, and replace anything earlier.
  • Severability. If a part of it cannot be enforced, the rest still applies, and the part is read as narrowly as it takes to be enforceable.
  • No waiver. Our not acting on a breach does not give up our right to act on it, or on the next one.
  • Assignment. We may assign this agreement in a merger, sale or reorganisation, with notice to you, and your information goes with it under the Privacy Policy. You may not assign it, and an account is not transferable.
  • Notices. We reach you at the email on your account, and a notice there counts as written notice. You reach us at support@acada.ac with "Legal notice" in the subject.
  • Electronic communications. Receipts, notices, policies and this agreement delivered by email or in the app satisfy any requirement that they be in writing or signed.
  • Sanctions. You may not use ACADA from a country or region under comprehensive United States sanctions, or if you are on a United States sanctions list; a payout account cannot be opened for one in any case.
  • Language. The English text of this agreement and the policies governs. A translated page, including one Google Translate produces, is a convenience.
  • Events beyond control. Neither of us is liable for a delay or failure caused by something outside our reasonable control, except an obligation to pay.
  • No third parties. Nobody but you and ACADA has rights under this agreement, except the people section 12 protects.
