Your dates stay private. The ovuLivo calculator runs entirely in your browser. When you enter the first day of your last period, cycle length or temperature readings, the page’s own code does the work on your device. None of it is uploaded to our servers, stored by us, or shared with anyone.
Why the calculator never contacts a server
All estimation happens locally through JavaScript. There is no submission step, no remote database of your cycle, and no profile built from what you enter. This is a deliberate choice — it keeps the tool fast, free and private, and it means we simply cannot see your data to misuse it.
Information We Collect
Because the tool computes locally, the dates you enter never reach us. What we do collect is deliberately minimal:
- A cookie for consent. We store a small choice in your browser so the cookie notice does not reappear on every visit. This holds a simple “accepted” marker, not any personal detail.
- Aggregated analytics. We may use privacy-friendly counters and logs to understand roughly how many people visit, which pages are popular, and what breaks. These are aggregate numbers, not a profile of you.
Advertising
Some pages may display advertising served by third-party networks. Those networks have their own privacy policies and may use cookies to serve relevant ads. We do not control these networks, and your use of them is subject to their policies rather than ours. The calculator itself still computes locally regardless of which ads appear.
Cookies
A cookie is a small file your browser stores. We use cookies only to remember your consent choice and to support aggregated analytics. Advertising networks may set their own cookies when you visit pages that show their ads. You can clear cookies anytime through your browser settings.
