Privacy Policy

When you create a Violingo account:

• Email address (required for authentication)
• Encrypted password — never stored in plain text
• Account preferences and settings
• Authentication tokens with expiration, encrypted in transit

• Vocabulary words you save and their translations
• Flashcard review history and spaced repetition progress
• Learning statistics (words learned, streaks, session duration)
• Study preferences and learning goals

• Show title and episode identifier linked to vocabulary words you save
• Language display preferences

When you use pronunciation practice, AI conversation, or Scene Sync listening, the app records a short audio clip only after you start it. The clip is sent to OpenAI to turn speech into text. We do not save your recordings.

If you use Community features:

• Your username and avatar
• Questions, comments, and posts you share, including any saved word, subtitle line, video, or milestone you attach
• Likes, "this helped" marks, and points you give or receive
• Reports you make, and people you block
• A summary of your learning (such as level, words this week, streak, and achievements) shown on your public profile. You can turn this off in your profile settings.

Anything you post in Community, and your public profile, can be seen by other Violingo users.

• If you join as a partner: your first and last name, country, referral key, earnings, and payout status
• Stripe or Wise collects the identity, bank, and tax details needed to pay you. If we pay you through Wise, we give Wise your name, email address and payout amount. We do not receive your full bank details.
• If you sign up with someone's referral key: which key you used. Partners see only totals, never who signed up or what they bought.

• Feature usage patterns and UI interactions
• Session duration and frequency
• Error reports, which may be linked to your account so we can fix the problem
• Browser type, OS, and extension version
• IP address (security only — not used for tracking)

• Subscription tier and billing cycle
• Credit balance and transaction history
• Billing email and country/region
• Last 4 digits of card (from Stripe — we never see full card numbers)

• Authenticate users and maintain secure accounts
• Match your playback position to our subtitle library and display translations
• Save and sync vocabulary across devices
• Run spaced repetition and review algorithms
• Track learning progress and statistics
• Improve AI features and translation accuracy

• Show your posts and public profile to other users
• Notify you when someone replies to you or marks your answer as helpful
• Keep Community safe: posts are checked automatically for harmful content before they appear, and posts reported by several users are hidden while we review them

• Link new users to the partner whose key they used
• Calculate partner earnings and send payouts through Stripe or Wise
• Prevent fraud, such as fake accounts or self-referrals

• Process payments and manage subscriptions
• Track credit usage and balances
• Send billing receipts and renewal reminders
• Handle refunds and comply with tax regulations
