Hello you,
The last decade ended with a PANG!
After reading about the lack of privacy in menstrual cycle trackers, I asked myself, “A privacy-first web-based period tracker? Is it even possible?”.
This seemingly innocent question led me to a talk on encryption in web applications held at 4 european tech conferences.
But also to the making of POW! — take charge of your menstrual cycle 😱

POW! in the Norwegian Financial Times
If you are done with babymaking and would like to take charge of your menstrual cycle, please let me know if I could pick your brains and invite you into the messy beta phase…

PS: The app will launch on March 8th, and you are invited to join me for launch brunch at my “home away from home”: Vespa & Humla (Grünerløkka, Oslo).
