Terms of Use

Last updated 31 August 2026

These Terms of Use (the "Terms") are an agreement between you and SwagEazy LLC, d/b/a KDV Labs, of 1755 Broadway Front 3 PMB 1245, New York, NY 10019, United States ("we","us", "our"), covering the Frasero mobile application (the "App"), this website, and anything else we offer under the Frasero name (together, "Frasero"). They are also the end-user license agreement for the App.

Please read section 15 (Disclaimers), section 16 (Limitation of liability) and section 19 (Dispute resolution) closely. They limit what we owe you, and if you live in the United States section 19 requires most disputes to go to individual arbitration rather than to a court or a class action.

1. Accepting these Terms

By downloading, installing, or using Frasero, you accept these Terms and our Privacy Policy, which is part of them. If you do not accept them, do not use Frasero.

2. Who may use Frasero

You must be at least 16 years old. If you are under the age of majority where you live, you may only use Frasero if a parent or legal guardian has read these Terms and agrees to them on your behalf – and by letting you use Frasero, they do agree, and they accept responsibility for your use of it.

You must also not be barred from receiving software under the laws of the United States or your own country. See section 21.

3. What Frasero is – and what it is not

Frasero is a practice tool. It shows Spanish exercises, records whether you answered them correctly, schedules them to come back, and explains the answer every time.

It is not, and we do not offer it as:

a teacher, a course, a tutor, or a substitute for any of them;
a qualification, a certification, or an assessment of your Spanish;
a CEFR examination or an official placement – the level labels B1 through C2 describe the difficulty we pitched an exercise at, not a certified measurement of you;
professional, educational, legal, medical, or any other kind of advice.

We do not promise a result. Frasero is built to help you notice mistakes and see them again. Whether your Spanish improves depends on you, and we make no representation that using Frasero will improve your fluency, your accuracy, your test results, or anything else.

4. Your license to use Frasero

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use one copy of the App on a device you own or control, and to use this website, for your own personal, non-commercial learning.

Where you obtained the App from the Apple App Store or Google Play, that license is further governed by the store's own usage rules, and you may use the App on any device those rules permit.

That is the whole of it. We reserve every right we have not expressly granted you.

5. What you may not do

You agree not to, and not to help or permit anyone else to:

copy, extract, scrape, crawl, download in bulk, index, or otherwise systematically collect the exercises, explanations, translations, or any other part of our content, by any means, automated or manual;
use our content to train, fine-tune, evaluate, or ground any machine-learning or artificial-intelligence model, or to build any dataset, corpus, or competing exercise library;
republish, redistribute, sell, license, rent, lend, or make our content available to anyone else, whether or not for a fee;
reverse engineer, decompile, or disassemble the App, or attempt to derive its source code or the structure of its content library, except to the narrow extent that applicable law expressly permits despite this restriction;
interfere with Frasero, probe or test its security, defeat any rate limit or access control, or access it other than through the interfaces we provide;
use Frasero to break the law, infringe anyone's rights, or send us anything unlawful, abusive, or malicious;
remove or obscure any copyright, trademark, or other proprietary notice.

These restrictions survive whatever happens to your access. We may enforce them without first suspending your use.

6. Our content and intellectual property

The exercises, their answer options, our explanations and translations, the way the library is selected, arranged, sequenced, and leveled, the scheduling behavior, the software, the Frasero name and logo, and the design of the App and this website are owned by us or licensed to us. They are protected by copyright, trademark, database, and other laws.

The library is protected as a compilation as well as item by item. Even where an individual sentence would not attract protection on its own, the selection and arrangement of the collection does, and taking a substantial part of it is an infringement whether or not you took any single item that is itself original.

Nothing in these Terms transfers any ownership to you, and no license is granted by implication, estoppel, or otherwise.

7. Reports, messages, and feedback

Frasero lets you report a problem with an exercise, and you can write to us. Anything you send us this way is a "Submission".

You keep whatever rights you have in your Submission. You grant us a worldwide, royalty-free, sublicensable license to use, store, reproduce, modify, and act on it, so that we can answer you and correct our content. That license runs for as long as we hold the Submission, and it does not override your right to have your data deleted– see our Privacy Policy and the deletion page.

What we change in Frasero because of your Submission is a different thing, and it is permanent. If your report leads us to correct, rewrite, or remove an exercise, that correction is ours to keep, and deleting your Submission does not undo it – the corrected exercise is part of our content and contains nothing about you. The same goes for any idea, suggestion, or feature request you send us: we may use it freely and indefinitely, and owe you nothing for it.

Do not send us anything confidential, anything you do not have the right to share, or anyone's personal information other than your own. We treat Submissions as non-confidential.

8. The content can be wrong

Our exercises and explanations are generated by AI. Language models draft each item, and a pipeline of automated checks, including cross-checking by other models, screens the result. If you find a mistake, we want to know: every card carries a report control.

Language is also not always a matter of one right answer. Regional usage varies, some sentences admit more than one natural completion, and an exercise may mark an answer wrong that a native speaker would accept.

Treat Frasero as practice, not as an authority. Where it disagrees with a dictionary, a grammar, a teacher, or a native speaker, they are right and we are wrong. You are responsible for anything you rely on Frasero for.

9. What Frasero costs

There is no charge for the current version of the App, and it contains no advertising. We may introduce paid features later. If we do, we will show you what they cost and what they include before you are asked to pay for anything, and you will never be charged for something you have not affirmatively agreed to buy.

Any purchase you ever make would be processed by Apple or Google under their terms, not by us. Refunds for store purchases are handled by the store, under its policy.

10. Third-party services

Frasero runs on services we do not control – Google Firebase, Sentry, the app stores, and others described in our Privacy Policy. We are not responsible for those services, and their availability, behavior, and terms are theirs, not ours. Links from Frasero to anywhere else are not an endorsement.

11. If you got the App from the Apple App Store

These terms are required by Apple and apply to you if you obtained the App from the App Store. Where they conflict with anything else in these Terms, they control for App Store copies.

Acknowledgment. These Terms are between you and us only, not with Apple. We, not Apple, are solely responsible for the App and its content.
Scope of license. The license granted in section 4 is non-transferable and limited to use on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be accessed by other accounts associated with you via Family Sharing or volume purchasing.
Maintenance and support. We are solely responsible for any maintenance and support services for the App. Apple has no obligation whatsoever to furnish any maintenance or support services for it.
Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you, if any. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty are our sole responsibility.
Product claims. We, not Apple, are responsible for addressing any claims you or a third party make relating to the App or your possession and use of it, including product liability claims, any claim that the App fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.
Intellectual property claims. If a third party claims that the App or your possession and use of it infringes that third party's intellectual property rights, we, not Apple, are solely responsible for the investigation, defense, settlement, and discharge of that claim.
Legal compliance. You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
Developer name and address. Questions, complaints, and claims about the App should go to SwagEazy LLC, 1755 Broadway Front 3 PMB 1245, New York, NY 10019, United States, info@frasero.com.
Third-party terms. You must comply with any applicable third-party terms of agreement when using the App.
Third-party beneficiary. You and we acknowledge and agree that Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and that upon your acceptance of these Terms, Apple will have the right – and is deemed to have accepted the right – to enforce these Terms against you as a third-party beneficiary of them.

12. If you got the App from Google Play

Your use is also subject to the Google Play Terms of Service. These Terms are between you and us; Google is not a party to them and is not responsible for the App. To the extent these Terms conflict with the Google Play Terms of Service for Play copies of the App, the Google Play Terms of Service control as to the relationship between you and Google.

13. Changes to Frasero and to these Terms

We may change, add to, or remove features, and we may pause or discontinue Frasero entirely. If we discontinue it for good, we will say so in the App or by email beforehand, where that is practical.

We may also update these Terms. If a change materially reduces your rights or increases your obligations, we will give reasonable notice in the App or on this website before it takes effect, and we will change the date at the top of this page. Continuing to use Frasero after a change takes effect means you accept the updated Terms; if you do not, stop using Frasero and delete the App.

14. Suspension and termination

You may stop at any time by deleting the App. We may suspend or end your access to Frasero at any time, with or without notice, if we reasonably believe you have breached these Terms, if it is necessary to protect Frasero or other people, or if we discontinue the service.

Sections 5, 6, 7, 8, 15, 16, 17, 18, 19, 20, 21, and 22 survive the end of these Terms.

15. Disclaimers

FRASERO IS PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, ACCURACY, AND NON-INFRINGEMENT.

WE DO NOT WARRANT THAT FRASERO WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT ITS CONTENT IS ACCURATE, COMPLETE, OR LINGUISTICALLY CORRECT, THAT DEFECTS WILL BE CORRECTED, OR THAT YOUR PROGRESS DATA WILL BE PRESERVED OR RECOVERABLE. YOU ARE RESPONSIBLE FOR KEEPING YOUR OWN RECORDS OF ANYTHING YOU CANNOT AFFORD TO LOSE.

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you. Nothing here affects any non-waivable statutory guarantee or consumer right you have where you live, and if you are a consumer in the EU, the UK, or another jurisdiction with mandatory consumer protections, those rights apply in full alongside these Terms.

16. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OPPORTUNITY, ARISING OUT OF OR RELATING TO FRASERO – INCLUDING ANY LOSS ARISING BECAUSE AN EXERCISE, AN ANSWER, OR AN EXPLANATION WAS WRONG – WHETHER THE CLAIM IS IN CONTRACT, TORT, STRICT LIABILITY, OR ANY OTHER THEORY, AND EVEN IF WE WERE ADVISED THAT SUCH DAMAGES WERE POSSIBLE.

OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO FRASERO IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM AND ONE HUNDRED U.S. DOLLARS ($100). FRASERO IS CURRENTLY FREE, SO FOR MOST USERS THAT AMOUNT IS $100.

These limits apply even if a limited remedy fails of its essential purpose. Some jurisdictions do not allow the exclusion or limitation of certain damages, so parts of this section may not apply to you. Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be excluded or limited.

17. Indemnification

To the extent permitted by law, you will indemnify and hold us harmless from any claim, demand, loss, liability, and reasonable legal cost arising out of your breach of these Terms, your misuse of Frasero, your infringement of anyone's rights, or any Submission you send us. We may take over the defense of any such claim at our own expense, and you will cooperate with us if we do. This section does not apply to the extent the law where you live prohibits it, and it does not apply to consumers in jurisdictions where such indemnities are unenforceable.

18. Governing law

These Terms and any dispute arising out of them are governed by the laws of the State of New York, United States, without regard to its conflict-of-law rules, and excluding the United Nations Convention on Contracts for the International Sale of Goods.

If you are a consumer, this does not take away your home protections. Where the mandatory consumer law of the country you live in gives you rights or protections that cannot be contracted out of, those continue to apply and this section does not override them.

19. Dispute resolution

19.1 Talk to us first

Before starting any formal proceeding, email info@frasero.com with a description of the problem and what you want. Most things are fixable this way, and we will try in good faith to resolve it within 30 days.

19.2 Arbitration and class-action waiver – United States residents only

This section applies only if you are a resident of the United States.If you live anywhere else, skip to section 19.5.

If we cannot resolve a dispute informally, you and we agree that any dispute, claim, or controversy arising out of or relating to Frasero or these Terms will be settled by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, rather than in court. The arbitration will be conducted by a single arbitrator, in English, and – unless you and the arbitrator agree otherwise – by written submission or telephone, or in New York County, New York if an in-person hearing is held. The arbitrator's award may be entered in any court of competent jurisdiction. The Federal Arbitration Act governs this section.

YOU AND WE AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS OR PRESIDE OVER ANY FORM OF CLASS PROCEEDING. YOU ARE GIVING UP YOUR RIGHT TO A TRIAL BY JURY AND YOUR RIGHT TO PARTICIPATE IN A CLASS ACTION.

If this class-action waiver is found unenforceable as to a particular claim or request for relief, that claim or request is severed from arbitration and heard in the courts named in section 19.5, while the rest of this section continues to apply.

19.3 What arbitration does not cover

Either of us may still:

bring an individual claim in small-claims court, if it qualifies and stays in that court;
seek an injunction or other equitable relief in court to stop infringement or misuse of intellectual property.

19.4 How to opt out

You can decline arbitration and keep using Frasero exactly as before. Emailinfo@frasero.com with the subject line "Arbitration opt-out", including your name and the email address or app identifier you use, within 30 days of first accepting these Terms. That is the whole process. Opting out affects nothing else, and we will not treat you differently for it.

19.5 Everyone else, and anything not arbitrated

Any dispute not subject to arbitration will be brought exclusively in the state and federal courts located in New York County, New York, and you and we consent to the personal jurisdiction of those courts.

Consumers outside the United States are not covered by section 19.2. If you are a consumer in the EU, the UK, or elsewhere, you may bring proceedings in the courts of the country you live in where your local law gives you that right, and nothing in this section takes that away. EU consumers can also use the European Commission's online dispute resolution platform.

20. Copyright complaints

If you believe something in Frasero infringes your copyright, email info@frasero.com with the subject line "DMCA" and include: your contact details; identification of the work you say is infringed; identification of the material in Frasero and where to find it; a statement that you believe in good faith the use is not authorized by the copyright owner, its agent, or the law; a statement that the information in your notice is accurate and, under penalty of perjury, that you are the owner or authorized to act for the owner; and your physical or electronic signature.

We respond to valid notices, and we may remove material and end access for anyone who infringes repeatedly. If you believe your material was removed by mistake, send a counter- notice to the same address.

21. Export controls and sanctions

Frasero is subject to United States export control and sanctions laws. You represent that you are not located in, and are not a national of or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, that you are not on any U.S. government list of prohibited or restricted parties, and that you will not use or export Frasero in violation of those laws.

22. General

Entire agreement. These Terms and the Privacy Policy are the whole agreement between you and us about Frasero, and replace anything said or written before.
Severability. If any provision is held unenforceable, it is limited or removed to the minimum extent necessary and the rest stays in force.
No waiver. If we do not enforce something, that is not a waiver of our right to enforce it later.
Assignment. You may not assign these Terms. We may assign them to a successor in connection with a merger, acquisition, reorganization, or sale of assets, or to an entity we form to operate Frasero.
Force majeure. We are not liable for failures caused by events beyond our reasonable control.
Notices. We may reach you in the App, on this website, or at any email address you gave us. Reach us at info@frasero.com.
Language. These Terms are written in English. Any translation is provided for convenience, and the English version controls.
Headings. Section headings are for reference and have no legal effect.
