Privacy Policy for Spatial Audio PDF Reader

Effective date: July 21, 2026

Spatial Audio PDF Reader is designed to let people explore PDF document layout

through HRTF spatial narration and on-device document analysis.


Information collection


Spatial Audio PDF Reader does not collect, sell, share, or transmit personal

information, browsing history, analytics, advertising identifiers, or PDF

contents to the developer or to an application server.

PDF files selected by the user are opened and processed locally in the Chrome

extension. Text extraction, page-layout detection, audio positioning,

translation when supported by Chrome, and image analysis run in the user's

browser or on the user's device.


Model downloads

On first use, the extension downloads voice and vision model files from

Hugging Face infrastructure. These files are program data required for local

processing and are cached by Chrome when possible. The extension does not send

the user's PDF, extracted document text, image crops, narration text, or

translation text with those model-download requests.


As with any normal internet request, the model host may receive technical

connection information such as an IP address and browser request headers under

its own privacy policy.


Permissions


The extension requests access only to the Hugging Face domains needed to

download its local voice and vision model data. It does not request permission

to read browsing history, read other websites, access tabs, access the

clipboard, access the camera or microphone, or download the user's PDFs.


Data retention and security


The developer does not receive or retain user data. Chrome may retain model

files in its local browser cache. Users can remove the extension and clear

Chrome site or extension data to remove locally cached data.


Children


The extension is a general accessibility tool and does not knowingly collect

personal information from children or adults.


Changes


If the extension's data practices change, this policy and the Chrome Web Store

privacy disclosures will be updated before the changed version is published.
