A period tracker with nothing to leak
Feelings is a privacy-focused period tracker designed for those who prioritize data security and control. Unlike many mainstream apps that upload personal health data to cloud servers, feelings keeps everything securely stored on the user's device, with no accounts, no cloud backups, and no analytics tracking. Users can log their flow, moods, and symptoms, then review past notes and receive honest, data-driven predictions about their cycle—always with transparency about the certainty of those predictions. The app also allows exporting a clean PDF report for medical consultations, making it a practical choice for users who value privacy and simplicity. Priced at a one-time fee of $14.99, feelings appeals to those tired of subscription models and concerned about their personal data being monetized, emphasizing that their body data isn't a revenue stream for anyone else.
Pros

- One-time purchase, no recurring subscription fees
- User-friendly interface with easy tracking of flow, moods, and symptoms
- Ability to export health data as a PDF for medical use
- Transparent about prediction accuracy and data limitations
Cons
- Limited features compared to comprehensive period tracking apps with community and integrations
