1. Agreement to Terms
Synapex Labs LLC ("Synapex Labs," "we," "our," or "us") operates this website and the products we make available, including Yomigua (collectively, the "Services"). By creating an account or otherwise using our Services, you agree to be bound by these Terms of Service. If you do not agree, please do not use the Services.
2. Description of Services
We provide this website and the products we make available, including Yomigua. Each product describes its current features and availability on its own website. Any paid features, if offered, will be described before purchase.
3. Accounts & Age Requirement
You must provide a valid email address to create an account and are responsible for maintaining the confidentiality of your login credentials. You must be at least 13 years old to use our Services. If you are under 18, you may only use the Services with the involvement of a parent or guardian.
4. Subscriptions & Payments
Paid features, if offered, will be described at checkout before you purchase. Synapex Labs has not selected a payment processor for its products at this time. If a paid feature launches, checkout will identify the payment provider and display the price, billing period, renewal, cancellation, and refund terms before you subscribe. The provider identified at checkout will process payment details; Synapex Labs does not store raw card numbers.
5. Pricing and Price Changes
Prices are not fixed for the life of your account. We may change the price of a plan, or the features and usage limits included in a plan, for reasons including: changes in the cost of the third-party services our Services depend on (AI model providers, hosting, and payment processing); changes in what a plan includes; changes in taxes, currency, or regulatory costs; or general adjustments to our pricing. A price change never applies retroactively to a billing period you have already paid for. If we change the price of a plan you are currently subscribed to, we will notify you at the email address on your account before the renewal date on which the new price would first apply — no fewer than thirty (30) days beforehand, except where the law of your jurisdiction requires that notice be given within a shorter or narrower window, in which case we will give notice within that window instead. That notice will state the current price, the new price, the date it takes effect, and how to cancel. You may cancel at any time before the new price takes effect, without penalty, and you will keep access through the end of the period you have already paid for. If you do not cancel before the new price takes effect, your subscription renews at the new price and you accept it. Where applicable law requires your affirmative consent to a price increase, the increase will not take effect for you until you give it. Promotional, introductory, and discounted rates apply only for the period stated at the time of the offer and revert to the then-current standard price afterward, which will be disclosed to you before the offer begins.
6. User Content & Acceptable Use
Some features across our Services (such as importing your own word lists) let you submit your own text. You retain ownership of what you submit, but you agree not to submit unlawful, abusive, hateful, infringing, or otherwise inappropriate content. You grant us a limited, non-exclusive license to store, process, and display content you submit solely to operate the relevant Service for you; we do not publish, sell, or redistribute your submitted content to anyone else. You are solely responsible for content you submit and for having the rights to submit it, and you agree to defend, indemnify, and hold Synapex Labs LLC and its officers, employees, and agents harmless from any claim, damages, liability, or reasonable expense (including attorneys' fees) arising from content you submit, your use of the Services, your violation of these Terms, or your violation of any law or the rights of a third party.
7. Intellectual Property
The Services themselves, including software, design, curriculum content, and branding, are owned by us and protected by applicable intellectual property laws. You may not copy, resell, or redistribute the Services or their underlying content without our permission.
8. Copyright Complaints (DMCA)
If you believe content available through one of our Services infringes your copyright, send a written notice to our designated agent at support@synapexlabs.com including: (a) a physical or electronic signature of the copyright owner or their authorized representative; (b) identification of the copyrighted work claimed to be infringed; (c) identification of the material you claim is infringing and information reasonably sufficient to locate it; (d) your contact information; (e) a statement that you have a good-faith belief the use is not authorized; and (f) a statement, under penalty of perjury, that the notice is accurate and that you are authorized to act on the copyright owner's behalf. We will respond to properly submitted notices in accordance with the Digital Millennium Copyright Act, including removing or disabling access to the identified material where appropriate. If you believe material was removed in error, you may send a counter-notice to the same address including your contact information, identification of the removed material and where it appeared, and a statement under penalty of perjury that you have a good-faith belief it was removed by mistake or misidentification. We reserve the right to terminate, in appropriate circumstances, the accounts of users who are repeat infringers.
9. AI Processing Is Required to Use the Services
Artificial-intelligence processing is a required and integral component of our Services, not an optional feature or an add-on setting. The generated material our Services are built around is produced by third-party AI providers, and there is no version of those Services that functions without them. To deliver a Service to you, we must transmit to those providers the material needed to generate your content, which varies by product and is described on that product's own Privacy Policy. By creating an account or using a Service, you acknowledge and agree to that transmission. Because this processing is necessary to perform our agreement with you, it cannot be switched off while you continue to use the Service; if you do not want your content processed this way, your remedy is to stop using the Service and delete your account.
THIRD-PARTY AI PROVIDERS ARE INDEPENDENT COMPANIES WE DO NOT CONTROL. Their handling of transmitted content — including whether and for how long they retain it, whether their personnel or systems may review it, and whether they use it to train, improve, or develop their own models, products, or services — is governed entirely by their own terms and privacy policies, which they set and may change at any time without our involvement or agreement. We do not control, direct, audit, or supervise those practices; we make no representation, warranty, or guarantee about them; and to the fullest extent permitted by law we are not responsible or liable for them, or for any retention, review, use, disclosure, or loss of content by a third-party AI provider.
You are responsible for what you send through our Services. Do not submit confidential information, trade secrets, credentials, financial or health information, personal information about other people, or anything else you would not want transmitted to and processed by an independent third party. Our Services are learning tools; they are not intended for, and must not be used to process, sensitive, regulated, or legally protected categories of data of any kind.
10. AI-Generated Content
Reading passages, synthesized audio, translations, AI-written definitions, and similar generated material across our Services are produced using artificial intelligence and automated language models. This content is created specifically for your session and is not written, recorded, reviewed, or verified by a human before you see or hear it. Audio is synthesized by a text-to-speech model and is not a recording of a human speaker. Where a Service cross-checks output against real reference sources (such as dictionaries), that is noted on the relevant product's own pages. AI-generated material may occasionally contain errors, and you should not treat it as an authoritative source for anything outside its intended learning context.
11. Disclaimer of Warranties
The Services are provided "as is" and "as available," without warranties of any kind, express or implied. To the fullest extent permitted by law, we disclaim all implied warranties, including merchantability, fitness for a particular purpose, title, and non-infringement, and we do not warrant that the Services will be uninterrupted, timely, secure, or error-free, or that any defect will be corrected. We do not guarantee perfection of AI-generated material (see Section 10).
12. Dispute Resolution and Arbitration
You and Synapex Labs LLC agree to resolve any dispute arising from these Terms or the Services through binding individual arbitration rather than in court, except that either party may bring an individual claim in small claims court, and either party may seek injunctive relief in court for infringement or misuse of intellectual property. Arbitration will be administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, and this arbitration agreement is governed by the Federal Arbitration Act. You and Synapex Labs LLC each agree to bring claims only in an individual capacity, not as a plaintiff or class member in any class, collective, or representative action. You may opt out of this arbitration agreement by emailing support@synapexlabs.com with your name, account email, and a clear statement that you opt out, within 30 days of the date you first agreed to these Terms; opting out does not affect any other part of these Terms.
13. Limitation of Liability
To the fullest extent permitted by law, Synapex Labs LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, or goodwill, arising out of or in connection with your use of the Services, even if we have been advised of the possibility of such damages. This includes, without limitation, any claim arising from the acts, omissions, terms, policies, data practices, outages, or changes in service of any third-party provider our Services depend on, including AI model providers (see Section 9), hosting providers, and payment processors. To the fullest extent permitted by law, our total cumulative liability to you for all claims arising out of or relating to the Services will not exceed the greater of (a) the amount you paid us in the twelve months before the event giving rise to the claim, or (b) one hundred U.S. dollars ($100). These limitations apply regardless of the legal theory on which a claim is based and even if a remedy fails of its essential purpose.
14. Termination
You may stop using the Services and delete your account at any time. We may also suspend or terminate your access at any time, with or without cause or notice, including if we discontinue a Service. Upon termination, your right to use the affected Service ends immediately, your data will be handled as described in our Privacy Policy, and any fees already paid remain non-refundable except where required by law. Provisions that by their nature should survive termination - including ownership, disclaimers, indemnification, and limitations of liability - will survive.
15. Governing Law, Venue & Severability
These Terms are governed by the laws of the State of Washington, USA, without regard to its conflict-of-law provisions. For any dispute not subject to arbitration under Section 12, you agree to the exclusive jurisdiction and venue of the state and federal courts located in King County, Washington. If any provision of these Terms is found unenforceable, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full effect.
16. Changes to These Terms
We may update these Terms from time to time. For minor changes — clarifications, corrections, formatting, updated contact details, or changes that add to your rights — we will update the "Last updated" date at the top of this page. For material changes, meaning changes that meaningfully reduce your rights or increase your obligations, we will give you advance notice at the email address on your account or through a prominent notice in the relevant product at least thirty (30) days before the change takes effect, except where a change must take effect sooner to comply with law or to address a security, safety, or legal risk. If you do not agree to a material change, your remedy is to stop using the Services and cancel any subscription before the change takes effect; if you continue to use the Services after that date, you accept the updated Terms. Changes to Section 12 (Dispute Resolution and Arbitration) will not apply retroactively to any dispute of which we had actual notice before the change took effect. Price changes are governed by Section 5, not by this Section.
