Privacy Policy

Overview

This Privacy Policy explains how Yapsu AI ("we", "us") collects, uses, shares, and protects information when you use the Yapsu AI mobile apps, website, web checkout, and related services (the "service"). Yapsu AI is an AI voice tutor for learning Japanese, operated by UPLAB SG SOFTWARE PTE. LTD. We are the controller of the personal information described in this policy.

Information We Collect

• Account information: your email address, your name if Sign in with Apple or Google shares it, and an account ID.
• Onboarding answers: your Japanese level, learning goals, interests, daily goal, reminder time, and whether you want tips and updates from us.
• Lesson content: your voice while you speak in a lesson, text transcripts of what you and the tutor say, and your lesson progress.
• Purchase information: your subscription status, product, price, and transaction history.
• Device and usage information: app events (for example, a lesson started), device model, operating system, app version, language, crash reports, and performance data.
• Advertising identifier (IDFA on iOS): only if you allow tracking when the app asks.
• Support messages and bug reports that you send to us.

We do not collect precise location, contacts, or photos.

AI and Speech Processing

Yapsu AI lessons use third-party AI providers (ElevenLabs, OpenAI, Anthropic, Google). When you speak in a lesson, the app records your voice. Your voice recording, the text of what you say, and the lesson context go to these providers to convert your speech to text, write the tutor's reply, and create the tutor's voice.

Our servers send these requests, not your device. We do not send your email address, account ID, device identifiers, or IP address to AI providers. The only account details the tutor receives are your name, so that it can address you, and your native language, so that it can explain in that language. Do not say your full name or other identifying details in a lesson if you do not want the providers to receive them.

This processing is necessary for lessons to work. You agree to it when you create an account or sign in. If you do not want your voice and lesson text sent to these providers, do not start a lesson. You can delete your account at any time.

We do not store your voice recordings. We store the text transcripts of your lessons to show your progress and continue your lessons, until you delete your account. We do not use your voice recordings or transcripts to train AI models. Each AI provider processes the data under its own API terms.

The app asks for microphone access only when you start your first speaking lesson. You can turn microphone access off in your device settings. Do not say sensitive personal information, such as health or payment details, in a lesson. AI replies can be wrong. See our Terms of Service.

Who Receives Your Information

We share information with these service providers. Each one receives only what it needs for its purpose.

• Anthropic (Claude): lesson transcripts and lesson context, to write the tutor's replies and corrections.
• ElevenLabs: your voice recordings during lessons and the tutor's reply text, to convert speech to text and to create the tutor's voice.
• OpenAI: your voice recordings during lessons, to convert speech to text when ElevenLabs is not available.
• Google Cloud: the tutor's reply text, to create the tutor's voice when ElevenLabs is not available.
• Google Firebase Analytics: app events, device information, and an app instance ID, to measure how the app is used.
• Sentry: crash reports, performance data, and device information, to find and fix errors.
• Meta (Facebook SDK and Conversions API): app install and purchase events, device information, and your advertising identifier only if you allow tracking, to measure which ads bring learners to Yapsu AI.
• RevenueCat: your account ID and App Store purchase information, to check your subscription status.
• Apple and Google: sign-in, and payments made through the App Store or Google Play.
• Web checkout payment processor: payment and billing details for purchases made through our web checkout. The processor handles your card details. We do not receive full card numbers.
• Vercel and Supabase: hosting of our servers, website, and database. Vercel Analytics measures website visits without cookies.

These providers must process information only for the purpose we give them and protect it. We do not sell your personal information. We may also disclose information when the law requires it, or to protect users, Yapsu AI, or others.

Tracking and Advertising

On iOS, the app asks if you allow tracking. If you allow it, we share your advertising identifier and app events (install, trial start, purchase) with Meta to measure our ads. If you do not allow it, we do not share your advertising identifier. You can change this at any time in iOS Settings > Privacy & Security > Tracking.

How We Use Information

• Provide lessons, speech recognition, tutor replies, and learning progress
• Personalize your lesson plan
• Manage accounts, subscriptions, and customer support
• Send reminders and, if you agree, tips and updates
• Find errors, monitor reliability, prevent misuse, and protect the service
• Measure our advertising, if you allow tracking
• Meet legal obligations

Legal Bases (EU, EEA, and UK)

• Lessons, your account, and subscriptions: performance of our contract with you.
• Crash reports, analytics, and security: our legitimate interest in a reliable and safe service.
• Advertising identifier and ad measurement: your consent in the iOS tracking prompt.
• Tips and updates: your consent, which you can withdraw at any time.
• Tax and accounting records: our legal obligations.

Data Retention and Account Deletion

• Account, onboarding answers, lesson transcripts, and progress: until you delete your account.
• Voice recordings: we do not store them. AI providers keep them only as long as their API terms allow.
• Crash reports and analytics: for the period set in each provider's settings, then deleted.
• Purchase records: as long as tax and accounting laws require.

You can delete your account in the iOS app: Settings > Delete Account. This deletes your account and the data linked to it from our database. You can also email us to ask for deletion. Deleting your account does not cancel an App Store or Google Play subscription. Cancel it in your store account settings.

Security

We use reasonable technical and organizational measures to protect the information we process, including encryption in transit and access limits. If a data breach affects you, we will tell you and the authorities as the law requires.

Your Choices and Rights

You can control microphone access and tracking in your device settings. You can ask us to stop tips and updates at any time. Depending on where you live, you can ask to access, correct, export, or delete your information, to restrict or object to processing, and to withdraw consent. California residents can also ask what personal information we collect and share, and we will not treat you differently for using these rights.

Email hello@yapsu.ai to make a request. We may need to confirm your identity. We answer within 30 days. You can also complain to the data protection authority in your country.

International Processing

Our providers may process information in countries other than your own, including the United States. Where the law requires it, we use appropriate safeguards for these transfers, such as standard contractual clauses.
