Welcome to MimiRecall (developed by Tryeno). We are committed to respecting and protecting your privacy. This Privacy Policy explains our practices regarding your information when using our mobile learning application.
✨ Core Commitment: MimiRecall is built on a privacy-first, zero-tracking architecture. All your study data remains exclusively on your device. We never collect, transmit, sell, or monetize your personal information.
1. Zero Personal Data Collection
MimiRecall does not collect, store, transmit, or share any personally identifiable information (PII).
- No Account Required: You do not need to register with an email, phone number, password, or social media account. You can start learning Japanese immediately without registering.
- No Remote Databases: We do not operate external user databases or maintain cloud profiles. All your learning material and progress remain strictly under your control.
- No Tracking & No Ads Frameworks: We do not track you across apps or websites, and we do not integrate third-party advertising tracking frameworks or data brokers.
2. Local Storage on Your Device
All your study data is stored strictly on your local device:
- Learning progress, daily review counts, SRS intervals, and streak records.
- Bookmarked vocabulary, kanji, kana, and grammar study cards.
- Personal study notes, custom decks, and audio recall preferences (playback speed, audio delay time).
3. Device Permissions & How They Are Used
MimiRecall only requests permissions that are strictly necessary to deliver educational functionality:
Used strictly for the on-device text scanner (OCR) feature to read Japanese text from physical books, notes, or menus. All image processing happens 100% offline on your device using local machine learning. Photos are never uploaded to any external server.
Used exclusively for scheduling local daily study reminders and review alerts that you configure. Notifications are managed locally on the device without external push servers.
Uses the device's built-in Text-to-Speech engine (iOS AVSpeechSynthesizer / Android TTS) to pronounce Japanese and English words locally. No audio recordings are collected or sent over the network.
4. Third-Party Services
- Zero Sale of Data: We do not sell, rent, monetize, or trade your data to third parties.
- External Dictionary Links: If you tap on external dictionary/search links, your web traffic is handled directly by that external website in an isolated browser window under their respective privacy policies.
5. Children’s Privacy (COPPA & GDPR Compliance)
Because MimiRecall does not collect any personal information from any user, it fully complies with:
- The Children’s Online Privacy Protection Act (COPPA) in the United States.
- The General Data Protection Regulation (GDPR) in the European Union.
Our application is completely safe for learners of all ages, including children under 13.
6. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated “Effective Date”. We recommend checking this page periodically to remain informed.
