Privacy Policy
Effective Date: June 7, 2026
Bijan John LLC, doing business as JADI ("we," "us," or "our"), operates the JADI mobile application (the "App"). This Privacy Policy explains what personal data we collect, how we use it, who we share it with, and your rights regarding your data.
By using the App, you agree to the collection and use of information as described in this policy.
1. Information We Collect
1.1 Account Information
When you create an account, we collect:
- Email address
- First name and last name
- Display name (optional)
- Password (stored securely in hashed form)
- Language preferences (native language, target languages, preferred formality)
1.2 Learning Activity Data
As you use the App, we collect data about your learning progress, including:
- Lesson and unit completion status
- Quiz attempts, scores, answers, and response times
- Spelling practice attempts and scores
- Flashcard review sessions and quality ratings
- Spaced repetition data (review intervals, ease factors, next review dates)
- Streak data (current streak, longest streak)
- Placement test results
1.3 Audio Recordings
When you use the pronunciation practice feature, the App records your voice through your device's microphone. These audio recordings are:
- Sent to our server for processing
- Forwarded to Google Cloud Speech-to-Text API for transcription and scoring
- Stored as audio file URLs alongside your pronunciation scores
Audio is only recorded when you explicitly initiate a pronunciation exercise. You may decline microphone access and continue using other features of the App.
1.4 Usage and Analytics Data
We automatically collect certain information about how you use the App, including:
- App interactions and navigation patterns
- Feature usage (e.g., which activities you start, complete, or exit)
- Session duration and timestamps
- Device type, operating system, and app version
- Crash reports and performance data
1.5 Subscription Data
If you purchase a subscription, payment processing is handled entirely by Apple (App Store) or Google (Google Play). We do not collect or store your payment card details. We receive subscription status information (active, expired, etc.) through RevenueCat, our subscription management provider.
1.6 Newsletter Information
If you sign up for our newsletter on our website, we collect:
- First name
- Last name
- Email address
This information is stored in Cloudflare KV and used to send you periodic updates about the JADI app, new podcast episodes, and learning tips. You may unsubscribe at any time using the link in any email we send, or by contacting us at jadi@tuta.com.
1.7 Website Analytics and Advertising Measurement
When you visit our website (jadiindo.com and its subpages) or our links page at links.jadiindo.com, we use the Meta Pixel from Meta Platforms, Inc. to measure the effectiveness of our advertising and to build audiences for future campaigns. The Meta Pixel collects:
- Pages you view and buttons you click (e.g., Download the App badges, newsletter sign-up)
- Device information (browser, operating system, IP address)
- When Automatic Advanced Matching is enabled, hashed (SHA-256) versions of email addresses or other identifiers you submit to forms on our site — the plaintext values never leave your browser
Meta processes this data to attribute conversions to our ads, build Lookalike audiences, and serve retargeting ads to people who have visited our site. You can opt out of Meta’s ad targeting at facebook.com/adpreferences/ad_settings, and EU/UK/California residents have additional rights described in sections 9 and 10 below.
The Meta Pixel runs only on our website — not inside the App itself.
