LangUp ("the extension", "we") helps you save words from web pages into your
personal LangUp vocabulary and study them later. This policy explains what the
extension collects, why, and how it is handled.

• Account information. When you sign in, we receive your email address and
  name — either from Google (if you use "Sign in with Google") or from the
  email and password you enter to register. This is used only to create and
  identify your LangUp account.
• Words you save. When you click "+" or use the right‑click menu to save a
  word, we store the word, the sentence it appeared in, and the URL and
  title of the page you saved it from. This is your learning material.
• Your chosen native language. Stored so we can translate saved words for you.
• Login session. Authentication tokens are stored locally in your browser
  (browser.storage.local) so you stay signed in. They are not shared with anyone.

We do not collect your browsing history, and the extension only sends data
when you explicitly choose to save a word or sign in. It does not read or transmit
pages you simply visit.

• To provide the core feature: saving words and building your vocabulary.
• To translate saved words into your native language and generate practice exercises.
• To keep you signed in across sessions.

We do not sell your data and do not share it with advertisers or data
brokers. Your data is sent only to the LangUp backend at
https://langup.piatek-magazyn.com, which stores your account and vocabulary.
Google is used solely to verify your identity when you choose Google sign‑in.


Your account and saved words are stored on the LangUp backend for as long as your
account exists. Login tokens live only in your browser and are removed when you
sign out.

• Sign out at any time from the extension popup to clear the local session.
• Delete your data / account by contacting us at the address below; we will
  remove your account and associated vocabulary.

The extension requests only the permissions it needs (storage, identity for Google
sign‑in, context menu, and access to the LangUp API host). The content script runs
on all sites so it can offer the "save word" button wherever you read, but it acts
only on the text you select and only sends data when you click save.


We may update this policy; the "Last updated" date above will change accordingly.
