Yes. In Digambar Jain tradition, samayik is not restricted to men only. It is a vow/practice for both śrāvak and śrāvikā.

So, a woman can do samayik in a temple, provided:

• the temple’s maryādā allows it,
• she follows śuddhi and proper conduct,
• she maintains silence, equanimity, and non-violence during samayik.

However, in some places, local temple rules or customary practice may differ regarding where and how samayik is performed. That difference is due to tradition and व्यवस्था, not because samayik itself is forbidden for women.

If you want, I can also explain this in simple Digambar terms or give the scriptural basis of samayik.
