Even in relatively less “traditional” women’s active communities, salaries (and any other income, such as book royalties, etc.) are turned over to the congregation. Sisters, even those who live alone, work out a budget annually, which will reflect their particular needs and even in some cases desires. For example, a sister teaching at a university might need more books, a newer computer, a car, different clothes, etc., than a sister who is retired in the motherhouse. But this is worked out not only as a budget but as a manifestation of obedience. Such a sister, for instance, would not simply apply for and accept a job with a university or whatever without discerning with congregational leadership, etc. And if they told her she was more needed in one of the congregation’s sponsored ministries (even if it were a high school, for instance, where she might prefer and be qualified to teach at the college level), she would almost always be expected to accept that in obedience.
Many communities allow for certain “recreational” budgets. This might include knitting supplies, or perhaps sheet music for a musician, or maybe even a Netflix subscription. Others do not. As with all things, it will depend on the community. I know more than one, for instance, where many retired sisters have their own tablets or laptops (generally not fancy). This is technically “for their use,” but it would also likely mean that they did not have something else.
