Lexio ("we", "our", or "us") operates the website lexio.site and the Lexio Chrome extension. This policy explains what data we collect, how we use it, and your rights.
Text you submit. When you look up a word or phrase, the word and the surrounding context text you provide are sent to our server and forwarded to Anthropic's Claude API to generate the definition. We do not store the text you paste into Lexio beyond the duration of the request.
Anonymous search logs. We record the searched word only (not the surrounding context) to generate trending word statistics shown on the homepage. These logs contain no user identifiers.
Account information. If you create an account, we store your email address and an encrypted password. If you sign in with Google, we store your email and Google account identifier. We do not store passwords in plain text.
Word bank. Words you save to your word bank are stored on our servers and associated with your account so they sync across devices.
Extension storage. The Chrome extension stores your language preference, saved words, and authentication token locally in your browser using chrome.storage.local. This data does not leave your device except when syncing with your account.
Anthropic. Lookup requests are processed by Anthropic's Claude API. Text you submit for lookup is subject to Anthropic's Privacy Policy.
Google Sign-In. If you use Google Sign-In, authentication is handled by Google. We receive only your name, email address, and a unique identifier from Google. This is subject to Google's Privacy Policy.
We do not use Google Analytics, Facebook Pixel, or any other third-party tracking service.
Account data and word banks are retained until you delete your account. Anonymous search logs are retained for up to 12 months. You can request deletion of your data at any time by contacting us.
All data is transmitted over HTTPS. Passwords are hashed using bcrypt and never stored in plain text. Authentication tokens expire after 30 days.
You may request access to, correction of, or deletion of your personal data at any time. To do so, contact us at the address below. We will respond within 30 days.
Lexio is not directed at children under 13. We do not knowingly collect data from children under 13.
We may update this policy occasionally. If we make material changes, we will update the date at the top of this page. Continued use of Lexio after changes constitutes acceptance of the updated policy.
