Privacy Policy

1. Information We Collect

S English collects only the data needed to deliver the language-learning service. Account information includes your name, email address, and a unique user ID created when you sign up. If you sign in with Apple's email-relay (@privaterelay.appleid.com), we receive only the relay address — never your personal Apple email — and we honor that relay for all service communications. Voice recordings: when you use shadowing or speaking practice, the audio you record is sent to our speech-to-text pipeline so we can score your pronunciation; recordings are processed and discarded within 30 days, are not used for advertising, and are never sold or shared with third parties for their own purposes. Lesson and progress data — which lessons you complete, your streak, and your saved vocabulary — power the in-app progress views. Subscription metadata (your Apple ID, transaction ID, plan, renewal status) is reconciled through RevenueCat as our App Store sub-processor; we do not see your payment card. Device and diagnostic data (app version, OS version, crash logs) are collected only to investigate problems.

2. Authentication and Sign-In

S English supports several sign-in methods. Each shares a different minimal set of data with us:

• Sign in with Apple — Apple shares a stable user identifier and either your real email or a private relay email. Only the email format you choose is shared; your Apple ID is never disclosed to us.
• Sign in with Google — Google shares your name, profile email, and avatar URL after you consent on Google's screen. We do not request additional Google scopes.
• Email and password — when offered, you provide your email directly and we store a salted hash of your password (never the plaintext).
• On all methods we create the same account record so your progress, vocabulary, and subscription follow you across sign-in changes.
• We never post to social profiles, never read contacts, and never request friend lists.

3. Subscriptions and Subprocessors

When you purchase a Sila Pro subscription inside the iOS app, the data flow involves:

• Apple Inc. — processes the payment, holds the receipt, and notifies us of subscription state changes. We never see your payment card.
• RevenueCat, Inc. — our sub-processor for normalizing App Store receipts. Receives your account user ID, transaction ID, plan, and renewal status; bound by a Data Processing Agreement.
• Our application servers — store the resulting Pro entitlement against your account so the app can unlock features.
• We do not share subscription data with advertisers or analytics providers.

4. How We Use Your Information

We use the collected information to:

• Operate the service and authenticate your account
• Score your pronunciation and provide AI feedback on your speaking practice
• Track your lesson progress, streaks, and vocabulary across devices
• Process and reconcile your subscription with the App Store
• Send transactional emails (receipts, security notices, account changes)
• Investigate crashes and improve the app — using only diagnostic data

5. Your Rights and Account Deletion

You have full control over your S English account:

• Delete your account directly inside the iOS app at Profile → Settings → Delete Account; deletion is confirmed via Sign in with Apple re-authentication.
• On deletion, your account record, voice recordings, lesson progress, vocabulary, and subscription metadata are scheduled for permanent erasure within 30 days.
• Active App Store subscriptions are not auto-cancelled by account deletion — cancel them separately in Settings → [your name] → Subscriptions to stop renewals.
• Request a copy of your data, correction of inaccurate data, or restriction of processing by emailing support@senglish.net.
• Withdraw consent for any optional processing at any time.
• Object to processing where we rely on legitimate interests.
• Lodge a complaint with your local data protection authority if you are in the EEA, UK, or California.

6. Data Protection and Retention

We implement appropriate technical and organizational measures including:

• Encryption in transit (HTTPS/TLS) for all client–server traffic
• Access controls limiting who on our team can read user data
• Server-side audit logs of administrative access
• Voice recordings retained for at most 30 days, then permanently deleted

No method of transmission over the Internet is 100% secure. We work hard to protect your information but cannot guarantee absolute security.
