1. Introduction

Search eBiblio is a browser extension (Safari, Chrome and Firefox) that searches the selected text in your region's eBiblio catalog. It does not collect, store, or transmit any personal data.

2. Data collection

Search eBiblio collects no data at all:

No analytics or telemetry
No crash reports
No user accounts
No tracking of any kind
No servers of its own

3. Local storage

The extension only stores your preferences (libraries shown in the context menu and your default library) using your browser's extension storage (browser.storage.sync). Your browser may sync these preferences across your devices (iCloud in Safari, your Google account in Chrome, or your Mozilla account in Firefox); they are never accessible to the developer.

4. Searches

When you search, the extension opens your region's public eBiblio website (https://<region>.ebiblio.es) with the selected text as the query — exactly as if you had typed it yourself. From that point on, your browsing is governed by the privacy policies of eBiblio and your regional library. The extension does not see, intercept, or store your eBiblio session, credentials, loans, or history.

5. Permissions

Selected text: only read when you invoke the extension (context menu, keyboard shortcut, or popup). It never reads pages in the background.
Context menus: to show the "Search on eBiblio" option.
Storage: to save your preferences.

6. Third-party services

None. No analytics SDKs, no ads, no trackers.
