As answered by people managing StackBlitz and Nineish Months.
Nineish Months's answer:
What really sets Nineish Months apart is that it’s built on a foundation of "Privacy by Design." While most pregnancy apps are built to collect and monetize your health data, Nineish Months is built to protect it. We don't have servers, we don't require accounts, and we never see your information. It’s a rare, truly private space that focuses entirely on the baby’s growth and the mother’s well-being, rather than on data collection.
Nineish Months's answer:
A person should choose Nineish Months if they want peace of mind. Most big-name competitors track your every move and sell that data to advertisers. With Nineish Months, you get a premium, beautiful, week-by-week experience with the absolute certainty that your personal health journey stays on your own phone. It’s the right choice for anyone who wants an elegant tracker without the "creepy" factor of being followed across the web.
Nineish Months's answer:
Our primary audience is the modern, security-conscious parent. These are people who appreciate clean, thoughtful design and want to stay informed about their baby's development, but are also deeply aware of digital privacy. They are often looking for an alternative to "Big Tech" health apps and prefer supporting independent developers who prioritize ethics and user safety over profit.
Nineish Months's answer:
Nineish Months was born out of a desire for a "quieter" and safer pregnancy experience. As an indie developer, I noticed that the most popular pregnancy apps were becoming increasingly cluttered and invasive regarding user data. I wanted to build something that I would actually want to use—an app that felt like a supportive companion, looked beautiful, and treated user privacy as a human right rather than an afterthought.
Nineish Months's answer:
The app is built natively for the Apple ecosystem using xcode, which allows for a fluid, modern, and highly responsive user interface. To ensure maximum security, we use local-on-device storage rather than cloud databases. This technical choice ensures that even the developer cannot access user data, as there is no central server to store it.
Nineish Months's answer:
Our "customers" aren't corporations; they are families and individuals who value their digital sovereignty. Expectant parents looking for a private way to track their first pregnancy. Privacy-conscious families who want to keep their health data off the cloud. Minimalist users who prefer a clean, focused, and ad-free experience. Tech-savvy parents who prioritize "Privacy by Design" software.
