Privacy
The short version: we keep only what we need to teach you, we never sell it, and we never show ads.
What we keep
- Your account: your email address and your password. The password is stored only as a one-way hash, so nobody, including us, can read it.
- Lessons you add: the title, the transcript or text you paste, and the video link if you give one. If you choose a video on your device, we store only its file name. The video itself never leaves your device.
- Your progress: how far you've watched, your answers to the check questions, the questions you missed (so they can come back for review), and any wish-log notes you write.
- Feedback you send: your message, plus which screen you were on, your screen size and your browser type, so we can find and fix the problem. If you delete your account, your feedback stays but is no longer linked to you.
- Usage counts: how many lessons and answers you've asked for each day, so everyone gets a fair share.
- Basic security records: your device's internet address is used briefly to block repeated sign-in attempts and abuse.
Who else sees it
- Our AI provider. To teach you, LessonBound sends the text of the part you're studying (and any question you type) to Hostinger AI Router, which passes it to an AI model (currently Anthropic's Claude) to write your lesson. We send only what's needed for that lesson, never your email or password. We don't sell this text and we don't use it to train AI.
- Our host. LessonBound runs on a Hostinger server in the United States.
- Email. If you ask to reset your password, Resend sends that email for us. It receives only your email address and the message.
- Video players. When you watch a YouTube, Vimeo or Loom video inside LessonBound, the video loads from that company, and their privacy policy applies to the player. We ask YouTube and Vimeo for their privacy-enhanced modes.
- Nobody else. No advertisers, no data brokers, no tracking or analytics companies.
Cookies
One cookie keeps you signed in. That's it: no advertising or tracking cookies.
Deleting your data
Go to Account → Delete my account. Your account, lessons, progress and notes are deleted right away. Copies in our nightly backups disappear within 14 days. You can also delete a single lesson from its page.
Your rights
You can ask for a copy of your data, ask us to correct it, or ask us to delete it at any time. Email us and we'll reply within 30 days.
Children
LessonBound is for people aged 13 and older. If you believe a child under 13 has an account, email us and we'll delete it.
Changes
If this policy changes, we'll update this page and the date at the top. Big changes will also be shown in the app.
