Contexto privacy policy

Last updated: June 14, 2026

Contexto runs entirely on your device, in Chrome, using a bundled Spanish language pack. It has a single purpose: to replace eligible English words on the pages you read with their Spanish equivalents and help you review the words you save.

Data collected

Contexto stores its state in chrome.storage.local on your own device, including:

• selected replacement density
• saved unknown-word and review state
• blocked-domain settings
• recent session words for local quiz behavior

This data never leaves your device.

Data we do not collect or sell

Contexto does not collect personal information, browsing history, or page content on any server. We do not sell, rent, or transfer your data to third parties, and we do not use it for any purpose unrelated to the single purpose above.

Network use

Contexto makes no runtime network calls. It does not send page text, browsing history, or translation requests to any server, and it uses no hosted backend or translation API. Unknown-word exports (CSV / Quizlet TSV) are generated locally from data already stored on your device.

Page access

Contexto's content script runs on the pages you visit so it can read page text and replace eligible English words in context — this is the only reason it needs broad page access, and the text is processed locally and never transmitted. Contexto skips form controls, code blocks, editable content, its own UI, non-English content, and any domains you block.
