Đọc Chuẩn Tiếng Anh does not collect any personal data.

WHAT WE DO NOT COLLECT
- No personally identifiable information (name, email, address, age, ID numbers).
- No health, financial or payment information.
- No credentials, passwords or authentication data.
- No personal communications.
- No location, IP address or GPS data.
- No browsing history or list of pages visited.
- No user activity (clicks, mouse position, scrolling, keystrokes).
- No page content — including the words you look up.

THE ONLY DATA STORED
Three display preferences, kept in your browser's own storage:
1. Whether the add-on is enabled on each supported site.
2. Whether to show the Vietnamese phonetics for both accents or only one.
3. Font size of the phonetics: same as the IPA, or slightly larger.

These stay in your browser. If you enable Firefox Sync, your browser syncs them
between your own devices — that is Firefox's mechanism, not a server of ours.
We operate no server that receives this data and cannot read it. Uninstalling
the add-on removes them.

SITE ACCESS
The add-on declares a narrow host permission for one domain only:
www.oxfordlearnersdictionaries.com. It does not request access to all sites.
On that domain it only reads the IPA string the page already displays,
converts it to Vietnamese phonetics locally, and inserts the result next to it.
It does not send page content anywhere, and does not copy, store or
redistribute the dictionary's content.

NO SELLING OR TRANSFER
We do not sell or transfer user data to third parties. We do not use user data
for any purpose unrelated to the add-on's single purpose. We do not use user
data for creditworthiness or lending purposes.
