Why I Built Cycletrack: A Privacy-First Period Tracker for My Daughters (and for You)
A personal project that became a public promise: simple tracking, real privacy, and lasting education
Cycle tracking is about more than dates. It’s about understanding your body, noticing patterns early, and having clear information when something feels “off.” I built Cycletrack to make that easier — without sacrificing privacy.
Hi, I’m MIRO PERDOCH — the developer behind Cycletrack. I’ve spent over 25 years building websites and web applications, and I also worked for 9 years as a certified pharmacy technician in a chain of community pharmacies on the south coast of England. Those two paths — technology and healthcare-adjacent work — are exactly why this app exists.
The original motivation was simple: I wanted my daughters to have a menstrual calendar that felt safe, respectful, and practical. Many apps are useful, but in a category this personal, privacy matters. I wanted a tool that could help with everyday tracking and also support understanding of symptoms that sometimes come with cycles.
What my pharmacy experience taught me
In community pharmacies, you see how often people live with symptoms quietly: painful periods, heavy bleeding, mood shifts, migraines, fatigue, skin changes, digestive discomfort, and more. You also see how hard it is to describe symptoms accurately when you’re tired, stressed, or in pain.
That’s why I believe tracking helps — not to self-diagnose, but to create a clearer picture. When you can say “this happens around day 1-2 of bleeding” or “pain spikes during ovulation week,” you’re no longer relying on memory alone.
What my developer experience changed
I built Cycletrack as a modern web app that feels fast and simple. As part of the process, I also wanted to learn and apply Progressive Web App (PWA) development properly — so the app can feel like a native install, work smoothly, and remain usable even when your connection is not perfect.
My guiding principle was: make it easy to log what matters and make privacy the default. A menstrual calendar should support you — not monetize you or pressure you.
What Cycletrack is designed to do
Cycletrack is built to help you track:
- Period dates and flow: the basic timeline your cycle is built on.
- Symptoms: cramps, mood, sleep changes, headaches, fatigue, digestive symptoms, skin changes.
- Patterns: what repeats, what changes, and what is worth paying attention to.
- Notes: stress, travel, illness, new routines — the context that explains “why this month felt different.”
Some people use Cycletrack just as a simple menstrual calendar. Others use it as a symptom diary to support conversations with a doctor. Both are valid — and the app should respect both.
Why I keep writing these educational articles
I want Cycletrack to be more than an app. I want it to be a small library of clear, practical education that helps people understand their cycle and the conditions that can be associated with it — from ovulation patterns and cycle variability to pain tracking and migraines.
My goal is to keep publishing articles that remain useful over time — a resource you can return to when you need answers, reminders, or a calmer explanation than you might find in random search results.
How to use Cycletrack in the most helpful way
If you’re new, start small for the first 2-3 cycles:
- Log period start/end and a simple flow level.
- Choose 3-5 symptoms you actually want to track (for example: cramps, mood, sleep, headaches, bloating).
- Add short notes only when something changes (travel, stress, illness).
Consistency beats complexity. Even one minute a day can reveal patterns that are hard to see otherwise.
A quick note about health advice
I’m sharing educational content based on practical experience and careful research, but this blog is not medical advice. If you’re dealing with severe pain, very heavy bleeding, concerning symptoms, or sudden changes, please speak with a qualified healthcare professional.
If this app helps you, I’ve achieved the goal
Cycletrack started as something I wanted for my daughters — a natural blend of what I know from years of building software and years of pharmacy work where menstrual health was part of everyday reality. If you use it to understand your body better, to track symptoms with more confidence, or to feel more prepared for a doctor’s visit, then it’s doing what it was built to do.
