1. Introduction
Synapex Labs LLC ("Synapex Labs," "we," "our," or "us") operates Yomigua and the Synapex Labs corporate website. This Privacy Policy explains what information we collect, how we use it, and the choices you have across our services. We do not knowingly collect personal information from children under 13; if we learn that we have, we will delete that account and its data.
2. Information We Collect
Account information: your email address and password, handled by our authentication provider, Supabase. Usage data: your learning progress, diagnostic scores, reading history, and spaced-repetition schedules, so our services can personalize your experience. Payment information: we do not collect card details on this website. If a product offers paid checkout, that checkout will identify the payment provider and the information it processes.
3. How We Use Your Information
We use your information to operate and improve our services: generating personalized practice content, tracking learning metrics, providing AI tutoring, administering paid features if we offer them, and providing customer support. We do not sell your personal information.
4. AI Processing and AI Model Training
Two different things are easy to confuse here, so we separate them. Processing by third-party AI providers is required. Our products cannot generate the content they exist to generate without sending the relevant material to an outside AI provider. This is not optional and cannot be switched off while using a Service, because there is no version of those Services that works without it. Our legal basis for it is performance of our contract with you, not consent, which means it is not something you are asked to agree to separately; if you do not want it, the remedy is to stop using the Service. What that provider then does with the transmitted content is governed by its own terms, not ours (see Section 6).
Improving our products is part of running them. Your learning history and progress are used both to operate a Service for you and to improve how it works — what gets taught when, how content is generated, how review is scheduled. There is no separate switch for this, because there is no honest way to separate it: these products personalise themselves from exactly that data, so running the app and improving the app are the same activity. Our legal basis is performance of our contract with you together with our legitimate interest in improving our own products, not consent. We do not sell your personal information, we do not share it for anyone else's advertising, and we do not hand it to a third party to train their models beyond the generation requests described in Section 6.
5. Cookies & Local Storage
Our websites and apps use browser local storage (not third-party ad-tracking cookies) to remember things like your session and theme preference, so the app doesn't need to re-ask on every visit.
6. Third-Party Service Providers
We share the minimum data necessary with the service providers that make our products work: Supabase (authentication and data storage), and Google's Gemini API (used to generate reading passages, synthesized audio, and explanations). We have not selected a payment processor for our products. If that changes, we will name the provider in checkout and update this policy before accepting payment. To generate content for you, the text involved is transmitted to that AI provider. Each provider handles data under its own terms and privacy policy, which we do not control, cannot audit, and which that provider can change at its own discretion. You should read those terms directly if this matters to you. Specifically for AI providers, their published terms typically distinguish between paid and unpaid API access, and can differ substantially between the two on how long content is retained, whether staff or automated reviewers may read submitted content, and whether submitted content is used to train or improve the provider's own models. Google's current terms for the Gemini API are published at ai.google.dev/gemini-api/terms. We are not responsible for a third-party provider's data practices, and no setting inside our products can override them — the only way to prevent your content from reaching an AI provider is not to use the Service.
7. Data Security
We take reasonable technical measures to protect your information, including access controls on our databases and encrypted connections between our apps and our servers. No system is perfectly secure, and we cannot guarantee absolute security.
8. Data Retention
We retain your account and learning data for as long as your account is active, subject to automatic limits within each product — for example, Yomigua keeps only your most recent 300 reading passages per language, and usage counters are discarded after 14 days. Neither affects your learning progress. You can permanently delete your account and all associated data at any time from within our apps, or export everything we hold first.
9. Children's Privacy
Our services are not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can remove it.
10. Your Rights
You can access, correct, or delete your personal information at any time through the Settings page of the app you are using, or by contacting us directly.
11. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will update the last-updated date at the top of this page and, where appropriate, notify you directly.
