OSCAR is an offshore sailing race viewer and post-race analysis app for sailors, coaches, race organizers, and sailing fans.

The app helps you explore public race tracking data in a clear mobile interface. Select a race, replay the fleet over time, inspect boat tracks on the map, compare competitors, and review how positions changed throughout the course.

Main features:
- Interactive race map with boat tracks, playback controls, and course context
- Race selector with public offshore and coastal sailing events
- Fleet view for browsing boats and checking competitors
- Ranking timelines to understand position changes during the race
- Performance charts for comparing speed, VMG, PPR, time, distance, and efficiency
- Sector analysis to review performance over specific parts of the course
- Routing comparison tools for post-race review and tactical analysis
- Account sign-in for saved preferences and account management
- Android app links for opening OSCAR mobile race URLs directly in the app

OSCAR is designed for post-race review rather than live race management. It is useful after a race when you want to understand where gains and losses happened, how different boats performed, and how the fleet moved across the course.

Typical uses:
- Review your own race after the finish
- Compare boats in the same fleet or class
- Follow offshore races from public tracker data
- Study tactical decisions and route choices
- Help coaches and crews discuss performance with shared visual evidence
- Browse notable sailing races and replay the action from a mobile device

The app shows race data from public sailing race tracking sources. It does not use your phone as a tracker and does not request device location. It also does not request access to contacts, camera, microphone, SMS, calendar, photos, videos, or audio files.

Some account features require sign-in. Users can delete their account from inside the app or request deletion through the OSCAR account deletion page. Public race tracker data and aggregate race analysis may remain available because they are not personal account data.

OSCAR is part of the DeepRegatta sailing analysis project and focuses on making race replay and performance review easier to use on mobile devices.
