In Jain Dharma, Kuldevi / Kuldev worship is not a part of the main scriptural path; it is a later, community‑custom.

If you ask “which sects don’t (or generally avoid) worship of Kuldevi?” then broadly:

1. Śvetāmbara Sthānakvāsī

- They do not worship idols of Tirthankars, and generally do not follow Dev–Devi or Kuldevi traditions. - Focus is on: - Namokār Mantra - Pravachan, meditation, and ethical conduct

1. Śvetāmbara Terāpanth (Acharya Bhikshu’s Terāpanth)

- Very strict about avoiding non‑scriptural rituals. - Do not promote Kuldevi / local goddess worship. - Emphasis is on: - Tirthankar-vandana - Guru, discipline, and internal sādhanā

1. Many serious scriptural Jains within other sects

- Even among Murti-pūjak Śvetāmbara and Digambar Jains, a number of families consciously avoid Kuldevi worship, keeping focus only on: - Arihant - Siddha - Ācārya - Upādhyāya - Sādhu

So, in simple terms:

• Sthānakvāsī and Terāpanth as sects clearly do not encourage Kuldevi worship.
• In other Jain sects, it depends on the family: some keep the Kuldevi tradition culturally, others completely avoid it to remain closer to pure Jain doctrine.
