Solo data stays on your device. Share / Join is opt-in and short-lived. There are no accounts, ads, or product analytics.
Data on your device
Roster names, jersey numbers, positions, notes, On/Off playtime, play history, and settings stay in your browser (IndexedDB). Clearing site data or using Clear roster removes that local copy.
Share / Join
If you tap Share, a 4-character code is created and the current roster and game state are sent to a short-lived room so up to eight invited devices can stay in sync. Rooms last about seven days.
What we do not collect
There are no accounts, advertising, or product analytics. The service does not ask for email, payment, or a login.
Ownership
You keep ownership of roster content you enter. Select Sideline's software, playbook, and marks remain the copyright holder's property.
