uByte (“we”, “us”, “our”) operates the website ubyte.dev — an online platform for learning programming through interactive tutorials, interview preparation, and certification exams. Our contact email is privacy@ubyte.dev.
Account data — when you register, we collect your name, email address, and a hashed password (we never store your password in plain text). If you sign in with Google, we receive your name, email, and Google account ID.
Learning progress — tutorial step completions, practice problem attempts, certification exam results, XP points, streaks, and achievements.
Code submissions — code you write and run in tutorials or interview prep is sent to third-party execution services (see “Third-Party Services” below) to produce output. We do not permanently store the code you run unless you explicitly share a snippet.
Shared snippets — if you click “Share” in the Playground, the snippet is stored on our servers and accessible via its unique link.
Payment data — subscriptions are processed by Paddle, our Merchant of Record. We never see or store your card details. We receive a Paddle customer ID and subscription status to activate your plan.
AI feedback — Pro users may request AI-generated code feedback. Your code and the step context are sent to a third-party AI API to generate a response. We cache AI responses briefly to reduce API costs.
Usage and analytics — we collect page views and conversion events via Vercel Analytics (privacy-friendly, no cross-site tracking, no cookies). Error reports are collected via Sentry.
Push notification subscriptions — if you consent to notifications, we store your browser push endpoint and encryption keys to deliver streak reminders.
Contact messages — if you contact us via the contact form or email, we retain your message to respond to it.
