Ovumcy
Your cycle, your terms.
Ovumcy is a privacy-first cycle tracker built in the open. The self-hosted web app is ready today; the mobile app, sync and managed cloud are on the roadmap. Your data never becomes a product.
One product you can run today. A roadmap you can watch.
This is the actual product — not concept art.
Cycle data is the most personal data there is.
In 2021 the FTC settled with a major cycle app after it shared sensitive health data with ad platforms despite privacy promises. This is not hypothetical. FTC →
Frequently asked questions
Does Ovumcy require a cloud account?
No. Ovumcy runs as a self-hosted application under your control — no account with us, no third-party cloud.
Where is my data stored?
On the server where you deploy Ovumcy. SQLite is the default; PostgreSQL is available for bigger setups.
Can I export my data?
Yes — CSV and JSON export with a documented stability contract, so your records stay portable.
Do I need technical knowledge to install it?
Basic Docker familiarity is enough. The repository ships a docker-compose.yml with working defaults.
Is Ovumcy a medical product?
No. Predictions are statistical estimates from the data you log — not diagnosis, treatment, or contraception.
Start where you are. Move when you’re ready.
Self-hosted web is one docker compose up away. Everything on the roadmap keeps the same promise: zero ad-tech.
