Use of Roll Call

Roll Call is provided to help users organize and play audio cues, manage team-related information, create Player Cards, and support introductions and Game Day activities.

You may use Roll Call for personal, team, recreational, school, community, or similar purposes, as long as your use is lawful and does not violate the rights of others.

You are responsible for how you use the app and for the content you add, create, play, export, or share through it.

Music, Audio, Photos, and Other Media Rights

Roll Call helps you organize, create, and play media-related content. Roll Call does not grant you any rights to music, recordings, photos, names, trademarks, likenesses, or other content.

You are responsible for making sure that your use of any music, audio, photos, recordings, names, likenesses, or other content is lawful and appropriate for your event, venue, league, school, organization, or community.

Some music, audio, photos, or other materials may be subject to copyright, licensing requirements, publicity or privacy rights, venue rules, platform restrictions, or other legal requirements. You are responsible for understanding and following those requirements.

Sidelark Labs is not responsible for content you add, import, record, create, play, export, or share using Roll Call.

Apple Music and Third-Party Services

Roll Call may use or interact with third-party services and Apple-provided services and frameworks, including Apple Music, Photos, Files, system sharing, system permissions, device storage, App Store services, and device backup services.

Your use of Apple Music, the App Store, iOS, iCloud, device backups, and other Apple services is subject to Apple’s own terms and policies.

Third-party services may change, become unavailable, or behave differently over time.

Roll Call allows you to export and import .rollcall team packages.

A .rollcall package may include team data such as player names, numbers, photos, audio settings, imported audio, recorded announcer intros, team colors, lineup details, and related app data.

When you export or share a .rollcall package, you are responsible for where that file goes and who receives it.

Anyone who receives a .rollcall package may be able to view or use the information contained in that package.

Do not export, share, or import team packages in a way that violates someone else’s privacy, rights, rules, agreements, or reasonable expectations.

Compatibility between package versions may change as Roll Call evolves. Older versions of Roll Call may not preserve every feature or type of data created by newer versions.

Player Cards and Sharing

Roll Call can create Player Card images using player, team, and photo information you provide.

You are responsible for making sure you have appropriate rights or permission to use the names, photos, team information, logos, colors, or other material included in a Player Card.

When you share or save a Player Card through Apple’s system sharing features, you control the destination and are responsible for how and where the image is distributed.

Sidelark Labs is not responsible for copies of Player Cards or other exported content after they leave the app.

Youth Teams and Player Information

Roll Call may be used by adults, coaches, parents, guardians, team helpers, or organizers for youth sports teams or other group activities.

You are responsible for deciding what player or team information to enter into Roll Call.

Please avoid adding sensitive personal information that is not needed to use the app.

If you use Roll Call for a youth team, you are responsible for making sure your use of names, numbers, photos, recordings, Player Cards, or other information is appropriate for your team, league, school, organization, and community.
