# Privacy and security

|
|
Subtitle and media files are read only after direct selection and stay in page
|
|
memory. No telemetry, analytics, account, upload, external font, codec, model or
|
|
other network destination exists. The production policy uses
|
|
`connect-src 'self'`; browser tests fail on non-local requests.
|
|
|
|
Subtitle text is rendered by React as text, not interpreted as HTML. ASS override
|
|
codes and WebVTT tags are preserved as inert source. TTML import rejects document
|
|
types and entity declarations and reads a deliberately flat, bounded profile; it
|
|
does not fetch referenced styles, images, fonts or other resources. Exports are
|
|
downloads chosen by the user. Browser-native media playback and Web Audio
|
|
decoding inherit browser codec support and may allocate substantial memory inside
|
|
the documented bounds.
|
|
|
|
Validation findings are editorial signals. They are not proof of accessibility,
|
|
broadcast conformance, synchronization quality or legal compliance. Cross-format
|
|
conversion can discard styles, positioning, regions, comments and metadata.
