The privacy-oriented Stardust app became the most downloaded free app on iOS in recent days precisely because it promises anonymous period data tracking, but it had to change the language of its disclosure. As of Monday, Stardust’s fine print read that they “may disclose your anonymized, encrypted information to third parties in order to protect the legal rights, safety and security of the company and the users of our services; enforce our terms of service; prevent fraud; and comply with or respond to law enforcement or a legal process or a request for cooperation by a government or other entity, whether or not legally required,” and now that last part reads “when legally required.”
It turns out that the best anonymous period-tracking app option in the US could very well be Planned Parenthood’s own app called Spot On which can be used without creating an account and stores the period data locally on the user’s phone.
