This Privacy Policy explains how Bukalemun ("we", "us", "our") collects, uses, and protects your information when you use our application (the "Service"). Bukalemun is operated by an individual based in the United Kingdom. By using the Service, you agree to the collection and use of information in accordance with this policy.
Account information
Email address and password (stored securely as a hashed value — we never see or store your plain-text password).
Profile preferences
Preferred language, formality preference (formal/informal), and gender preference (used for grammatical accuracy in translations).
Messages
Message content you send through the Service, including the original text and its translation, timestamps, and message counts (used to enforce free tier limits).
Payment information
If you subscribe to a paid plan, payment is processed by Stripe (web) or by Apple via RevenueCat (iOS). We do not store your card details. We retain a Stripe or RevenueCat customer reference ID to manage your subscription.
Technical information
We may collect basic technical data (such as browser type and device type) to maintain and improve the Service.
We use your information to: provide and operate the translation and messaging features; maintain your chat history; enforce free tier message limits and manage subscriptions; communicate with you about your account; and improve and maintain the Service.
To provide real-time translation, your messages are sent to DeepL (for core translation) and Anthropic's Claude API (for grammatical refinement). These providers process message content solely to return a translation. Messages are stored in our database (hosted by Supabase) so that you and your conversation partner can view chat history. Data is encrypted at rest. We do not use end-to-end encryption. This means messages are technically accessible to us as the Service operator, though we do not access message content except as necessary to operate, maintain, or debug the Service, or as required by law.
We use the following providers to operate the Service: Supabase (database hosting, authentication), Vercel (application hosting), Stripe (payment processing), RevenueCat (subscription management for iOS), Apple (App Store payment processing for iOS), DeepL (message translation), Anthropic (translation refinement), and Resend (transactional emails). Each provider has its own privacy policy governing how they handle data.
We retain your account information and message history for as long as your account is active. You may request deletion of your account and associated data at any time by contacting us.
UK & EU users (UK GDPR / EU GDPR)
You have the right to access, correct, or delete your personal data; restrict or object to processing; data portability; withdraw consent; and lodge a complaint with the ICO (UK) or your local supervisory authority.
US users
Depending on your state, you may have rights under applicable state privacy laws such as the CCPA, including the right to know what data is collected and the right to request deletion.
We take reasonable measures to protect your information, including encryption at rest and in transit, and Row Level Security restricting data access to authorized users only. However, no method of electronic storage or transmission is 100% secure.
The Service is not intended for individuals under the age of 16. We do not knowingly collect personal information from children.
