A Jain house temple is a special place where people who believe in a religion called Jainism can go to worship and pray. Think of it like a very special room in someone's house that is used for praying and giving thanks to the gods in the Jain religion.
The temple usually has a statue or picture of a god or goddess that the Jains worship, and people who go there often make offerings of things like flowers, fruit and sweets to show their devotion.
In a Jain house temple, there are also important books called scriptures that are read and studied to help people learn more about their religion and the teachings they should follow to be good Jains.
It is important to be quiet and respectful in a Jain house temple, as it is a holy and peaceful place where people go to connect with their faith and reflect on their lives.
