Code of Conduct

The following Code of Conduct is inspired by that from other prominent conferences such as ScalaDays or Scala eXchange.

ScalaSphere is dedicated to providing a harassment-free experience for everyone, regardless of gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, nationality, age or religion. We do not tolerate harassment of participants in any form. Please show respect for those around you. This applies to both in-person and online behavior.

All communication should be appropriate for a technical audience,

including people of many different backgrounds. Sexual language, innuendo, and imagery is not appropriate for any conference venue, including talks.

If you are being harassed, notice that someone else is being harassed, or have any other concerns, please contact a member of staff immediately. If an individual engages in harassing behaviour, the ScalaSphere staff may take any action they deem appropriate, including warning the offender or expulsion from the event.
We expect all attendees to follow above rules during our ScalaSphere DevTools Summit.
