I have been using this application for about 3 years, it is the best and now it helps me a lot especially during my pregnancy, with the notes to keep track of my symptoms in the prenatal and before being pregnant the “try to conceive” mode was very helpful, in addition, being able to have the Clue Plus for a year and at a low cost is really great. Always recommend this app. The best app I have been using this application for about 3 years, it is the best and now it helps me a lot especially during my pregnancy, with the notes to keep track of my symptoms in the prenatal and before being pregnant the “try to conceive” mode was very helpful, in addition, being able to have the Clue Plus for a year and at a low cost is really great.

clue plus is literally the only app subscription i have. while it might not seem like much, the gender neutral language that clue uses throughout the app is a huge plus for me as a nonbinary person. it gets tiring to always hear “WOMEN’S health” and “FEMININE hygiene products” when i just want to take care of my body. i also appreciate the options to track HRT or to track experiences without a period (super helpful for those on certain types of birth control). and especially with all the chaos in the US government right now, i’m really glad to use an app with such a dedication to digital privacy. (their blog posts are also great btw, especially if you’re like me and had exactly zero discussion of LGBTQ+ stuff in high school sex ed.) very trans friendly! clue plus is literally the only app subscription i have. while it might not seem like much, the gender neutral language that clue uses throughout the app is a huge plus for me as a nonbinary person. it gets tiring to always hear “WOMEN’S health” and “FEMININE hygiene products” when i just want to take care of my body. i also appreciate the options to track HRT or to track experiences without a period (super helpful for those on certain types of birth control). and especially with all the chaos in the US government right now, i’m really glad to use an app with such a dedication to digital privacy.

I’ve enjoyed using Clue through multiple phases of my menstrual journey from knowing when to expect it, to tracking fertility, to monitoring pregnancies and now navigating perimenopause/ menopause. It lets me track relevant symptoms and be better prepared.

Standing up for WOMEN!!! I’ve used Clue for years. I love how it keeps me on track. Now that I’m, maybe, entering menopause, it helps me see new patterns. But after I received Clue’s privacy promise, I couldn’t love your app more!!! Thank you for standing up for women, and standing up for our privacy and autonomy! I’m beyond impressed. Steps like this pave the way for the future we deserve!!! Way to go, Clue!! Standing up for WOMEN!!! I’ve used Clue for years. I love how it keeps me on track.

As Americans, we deeply appreciate your commitment to protecting user data. Please continue to stand strong—not just by resisting subpoenas, but by refusing to sell so-called “anonymized” data to brokers. That’s how most government access happens. True privacy means keeping all our data safe, not just the obvious parts. Thank you for protecting our privacy! As Americans, we deeply appreciate your commitment to protecting user data.
