Cycles of Influence
Decide who knows your body
Tracking menstrual cycles with an app has become very popular for anyone with a period, but period tracking has a long history dating back to prehistoric times. Whether you’re interested in general menstrual health or trying to avoid or achieve pregnancy, keeping track of your period is very helpful. It can give you important insights into your body and alert you to when something is off.
There are various ways to track your menstrual cycle with the help of technology, including cycle tracking apps (also known as period trackers or fertility tracking apps), but many options make this sensitive information available to companies, data brokers and governments.
In this Data Detox guide, you’ll explore ways to track your cycle and may even discover a method that works best for you—as well as how to do it as safely as possible.
Let’s cycle through this together!
What Is Cycle Tracking and Who Cares About It?
Cycle tracking is the process of noting down the dates and details of your menstruation and other related experiences such as pain, skin condition, mood, and temperature as they change throughout your cycle. This process can be referred to as cycle tracking, ovulation tracking, or period tracking.
A menstrual cycle begins on the first day of your period (bleeding) and ends with the start of your next period. A menstrual cycle can range on average from 21 to 40 days. Throughout the cycle, you go through different phases as hormone levels change: pre-ovulatory, ovulatory, pre-menstrual phase, and finally menstruation or period. Each of these phases can have a different physical or emotional impact. People can experience feeling more active, energised, and social during the ovulation period, while some might note feeling more tired or bloated before their period. During menstruation, people can experience cramps or fatigue. But everyone’s period is different and everyone’s experience of their overall cycle is unique.
There are many advantages to tracking your menstrual cycle. It can give you insights into the fluctuations your body goes through—and knowing what’s going on in your body can be very empowering. By tracking these details, you may notice changes that you’d like to check with a doctor. Tracking your cycles can also help you take charge of your fertility.
But the process of tracking menstrual cycles can also be used against you by various groups—even without your knowledge or consent. This is made easier when you use an app that doesn’t take care of your privacy. For example, advertisements can be targeted at you to exploit hormonal fluctuations during your cycle. Depending on where you are in your cycle—ovulation or pre-menstrual—you may be sent ads for certain products with tailored messages. During ovulation you may receive advertisements for lingerie or make-up, while during the pre-menstrual phase you might see products related to parenting and nesting. These ads are based on research conducted by marketing experts and may also reinforce stereotypes about gender.

- What other individuals or institutions seek access to your cycle data?
- Are you trying to prevent or achieve pregnancy?
- Are you taking hormones and want to track their impact on your cycle?
- Do you prefer a gender-neutral tracking option and what apps allow for that?

In many countries, reproductive choices are severely restricted and abortions or contraceptives are illegal. This means that access to your cycle data can seriously put your safety and those around you at risk. Here are some articles that can help you understand how to navigate the choice of whether or how you can keep your data safe and how to safely access abortions.

In this Data Detox guide you learned how to choose a safe and useful tracking option, so that you are in charge of who knows what about your body. Here’s a quick summary:
Cycle-related data can reveal a lot of information about you. Data about reproduction are sensitive. Depending on your situation and where you live, this intimate information could become exploitative or be used against you.
There are many different tracking options available, but most of them are neither private nor secure: apps share data and other online tracking options that can be accessed by governments and companies.
When choosing an option for yourself, think about what makes a tracking option safe:
- Your data is stored safely and securely. This means your information should be encrypted, stored locally and password protected. The data should not be shareable with third parties or law enforcement.
- It’s easy and quick to delete your information.
- No unnecessary data is tracked without your knowledge.
Finding the best tracking option is your individual choice, but remember that data collection is something that affects everyone with a period, so you’re not alone in navigating this. You can help others become aware about who is trying to know their bodies, too—next time you talk about menstruation with your friends, tell them about what you’ve learned!
