Which Health Apps Prioritise User Data Privacy and Security?
It's the question we get asked more than almost any other: "Just tell me which apps are actually safe to use." It's a fair question, and it deserves a real answer, not just a list of logos with checkmarks next to them.
The honest truth is that "safe" isn't one fixed label a company earns once and keeps forever. It's an ongoing pattern of decisions: what an app collects, who it shares that with, how it stores it, and how it responds when something goes wrong. Some apps are consistently good at this. Others get worse over time, often quietly, through a privacy policy update most users never read. So rather than naming names here, let's talk about what actually separates the apps that take your data seriously from the ones that just say they do.
What "prioritising privacy" actually looks like
Apps that genuinely put user data first tend to share a few habits in common.
They collect less, on purpose. The best apps ask themselves what they actually need to function, not what they could get away with collecting. If a period tracker doesn't need your precise location or your contacts list to work, it doesn't ask for them.
Consent is specific, not bundled. Instead of one giant "I agree" checkbox covering ten different uses of your data, privacy-first apps let you say yes to some things and no to others, like turning on research participation or opting out of personalised ads separately.
Sharing with third parties is the exception, not the default. When data does go to a partner, for analytics or customer support, for example, it's disclosed clearly, and it's rarely used for advertising your most sensitive health details.
Deletion actually means deletion. You can close your account and remove your data, including backups, without having to email support and hope someone follows up.
Security is layered, not just a checkbox. Encryption both in transit and at rest, regular independent security audits, and a clear, published way to report vulnerabilities are all signs a company treats security as ongoing work, not a one-time badge.
They tell you what happens if the company is sold. A trustworthy privacy policy addresses what happens to your data in a merger, acquisition, or shutdown, instead of staying silent on it.
They're transparent when things go wrong. Every company can have a security incident. The ones worth trusting disclose it clearly and quickly, rather than downplaying it or staying quiet until they're forced to.
Why this is genuinely hard to judge on your own
Here's the uncomfortable part: even a careful, well-informed person can spend twenty minutes reading a privacy policy and still not be sure. Legal language is written to be technically accurate, not easy to interpret, and it changes without much notice. Two apps can look almost identical on the surface, with one quietly sharing far more data than the other.
That's the gap we built SheRanked to close.
Something new is coming from SheRanked
We're about to launch the first dynamic leaderboard for women's health apps: a living, continuously updated ranking built specifically around data privacy and security, alongside the medical credibility our team already reviews for.
Instead of a single review that goes stale the moment a company updates its terms, the leaderboard works more like a snapshot that's always current. New apps get added as we review them. Existing apps move up or down as their policies, practices, or track record change. And instead of digging through a 40-page privacy policy yourself, you'll be able to see, at a glance, how the women's health tools you're actually considering compare to each other on the things that matter most.
The goal is simple: quick, easy access to the information you need to make an informed decision about the tools you're trusting with some of your most personal data, updated as often as the apps themselves change.
