Slovak women rely on menstrual tracking apps to log cycles, symptoms and contraception choices. A Mozilla investigation found that several popular tools route sensitive details through third-party services, sometimes without clear disclosure in privacy policies.

Where the data actually travels

Of the six apps examined, Stardust stood out for sending pregnancy status, mood logs and physical symptoms to an analytics firm not mentioned in its policy. Other apps share device identifiers with large advertising networks, creating a potential link between app use and personal identity.

The research makes clear that even basic usage can become part of a wider digital profile. Only one app keeps every record strictly on the device and requires no account.

The missing local layer

The study focuses on app code and company practices yet says nothing about practical steps women can take outside digital ecosystems. Many users want guidance on privacy settings, secure device setup or even non-app alternatives for health tracking.

These needs sit outside the scope of software audits. They point instead to everyday tasks that require human expertise in the same city or neighbourhood.

Control without another login

Task4you.sk lets people post exactly these requests: a local IT-savvy helper to audit phone permissions, a privacy-aware consultant for one-off advice, or a tutor who explains data risks face-to-face. No profile on a health platform is required.

The marketplace simply matches the task with someone nearby who can complete it today.

• Check which apps actually store data only on your phone
• Post a task for local help with privacy settings instead of downloading another tool
• Choose in-person services that leave no digital trail by default

Apps promise convenience while quietly moving personal records. Local arrangements keep both the task and the data in the same place.
