Companies that collect data from people online often know their most sensitive health information.
They can find that information through web searches and tracking programs.
Privacy experts now fear this information could be used to spy on pregnant women if the U.S. Supreme Court overturns Roe v. Wade--the court's 1973 ruling protecting the right to end a pregnancy.
For now, the data is mostly used to target advertising, like baby products shown to pregnant women.
But the information could become evidence in a criminal case.
And it is something that worries those who support a woman's right to end a pregnancy, or abortion.
"The value of these tools for law enforcement is for how they really get to peek into the soul," said Cynthia Conti-Cook.
She is a Ford Foundation technology expert.
In public, there are security cameras, license plate readers and other tools to record people's movements.
And the technology has gotten far ahead of the laws that govern them.
Laws in the U.S. are far behind those passed in Europe in 2018.
Vice News found that until this month, anyone could get data on clients at more than 600 Planned Parenthood offices around the country for as little as $160.
Planned Parenthood is a non-profit provider of healthcare including abortions.
The information included probable patient addresses, earning levels, time spent at the health provider, and the top places people visited before and afterward.
That is possible because the current law protects privacy in the doctor's office but not information that mobile devices and tech companies collect.
Some American states are starting to push back, setting limits on tools that gather this information.
The state of Massachusetts, through a legal settlement, stopped a Boston company from sending anti-abortion advertising to women inside health offices that offer abortion services.
In Michigan, voters changed the state constitution to require police to get a warrant before searching someone's data.
And in California, voters passed a digital privacy law that lets people delete the data that companies collect about them.
Still, the responsibility to protect one's privacy lies mainly with the user who must understand complex data agreements and policies.
The rising concerns have forced Apple, Google and other tech companies to add measures limiting the sale of consumer data.
That includes Apple's launch of its App Tracking Transparency feature, which lets users block apps from tracking them.
Abortion rights activists suggest that people in conservative states leave their phones at home or turn off location services when seeking health care.
They also advise studying the privacy policies of health apps they use.

He said there are "very, very few people who have the savvy to do everything" needed to protect themselves.

从网上收集数据的公司通常知道人们最敏感的健康信息。
他们可以通过网络搜索和跟踪程序找到这些信息。
隐私专家现在担心，如果美国最高法院推翻罗诉韦德案——该法院1973年做出的保护女性终止妊娠权利的裁决——这些信息可能会被用来监视孕妇。
目前，这些数据主要用于定向广告，比如向孕妇展示婴儿产品。
但这些信息可能会成为刑事案件的证据。
这也让那些支持女性终止妊娠(即堕胎)权利的人感到担忧。

Vice新闻发现，直到本月，任何人都可以以160美元的价格在全国600多个“计划生育”办公室获得客户数据。
“计划生育”是一家非营利性组织，提供包括堕胎在内的医疗卫生服务。
这些信息包括可能的患者地址、收入水平、在医疗机构停留的时间、以及她们在之前和之后最常去的地方。
这是有可能的，因为目前的法律保护的是医生办公室的隐私，而不是移动设备和科技公司收集的信息。
美国一些州开始反击，对收集这些信息的工具进行限制。
马萨诸塞州通过一项法律协议,阻止了波士顿一家公司向提供堕胎服务的卫生所内的女性发送反堕胎广告。
在密歇根州，选民修改了州宪法，要求警察在搜查某人的数据之前必须获得搜查令。
在加利福尼亚州，选民通过了一项数字隐私法，允许人们删除公司收集的关于他们的数据。
不过，保护个人隐私的责任主要在于用户，他们必须了解复杂的数据协议和政策。
日益加剧的担忧迫使苹果、谷歌等科技公司增加了限制销售消费者数据的措施。
其中包括苹果推出的应用程序跟踪透明度功能，该功能允许用户阻止应用程序跟踪他们。
堕胎权活动人士建议，在保守的州，人们在寻求医疗卫生服务时，最好将手机留在家中或关闭定位服务。
他们还建议研究所使用的健康应用程序的隐私政策。
