About Lindara
Helping schools share photos with care.
PT Lindara Data Indonesia is a Jakarta company. We build Halo, software that changes selected faces in school photos so staff can review each result before deciding whether to share the photo.
Why Lindara exists
Lindara began from concern about children’s digital safeguarding. Children remain vulnerable both online and in the physical world, and a photo shared publicly can reveal more than a school intends.
Halo lets school teams change selected faces and review each result before they decide what to share. It helps reduce recognition but does not guarantee anonymity. It supports, and does not replace, each school’s permissions and safeguarding checks.
