Menstrudel: The Private, Open Source, Offline Period Tracker & Cycle Calendar

Menstrudel is the simple, powerful, and private period tracker designed to give you complete control and true ownership over your health data. Unlike cloud-based solutions, Menstrudel protects your privacy and security.

THE 100% OFFLINE DIFFERENCE: YOUR DATA, YOUR CONTROL We prioritise your privacy above all else. When searching for a trusted period tracker or menstrual app, privacy is key.

• 100% Offline Storage: All your sensitive menstrual cycle data, symptoms, and logging information is stored securely and completely offline on your device.

• No Servers, No Cloud: Your data is never sent to any external server or third party. There are no accounts and no tracking.

• Biometric Security: Protect your private health information with immediate biometric access controls.

If you are looking for a completely offline period tracker solution, Menstrudel is the choice for data ownership.

OPEN SOURCE & TRANSPARENCY Trust requires transparency. Menstrudel is an open source project, meaning the code is publicly available for anyone to audit and review.

• Auditable Code: Our commitment to open source ensures you know exactly how your data is handled. We are built on community trust, not corporate data collection.

• Community Focused: Help us improve your favorite offline period calendar by contributing to the project.
