Your privacy
Privacy Policy
Last updated: October 2026
This is the privacy notice for ovulivo.com, operated by OvuLivo ("we", "us"). It covers the information we deal with and the options open to you. Briefly: your last period date and cycle length are computed locally and never leave your machine.
What this policy applies to
OvuLivo is an ovulation calculator that predicts ovulation and the fertile window from the last period and cycle length and lays them onto a cycle calendar. It estimates the next ovulation by counting back roughly fourteen days from the projected next period and marks the fertile window around it, which is why the answer moves when the cycle length changes. Everything below concerns that specific calculation and the values it involves, and nothing beyond it.
Practically, all the calculation needs is your last period date and cycle length. Typical reasons people open OvuLivo include planning around an irregular cycle, and in every case the work happens on the visitor's own device rather than ours.
Your inputs
On ovulivo.com the computation never leaves the browser. OvuLivo reads your input in the page itself, produces the result there, and sends nothing over the network — which is also why the tool goes on working if you disconnect after loading it.
When this policy is revised
We may update this page as the site changes. Material changes are reflected in the "last updated" date above.
Information collected as you browse
The hosting layer sees what any web server sees — client address, requested path, user agent, time — and that is the limit of it. None of those records contains the values you type into the ovulation calculator, because those never reach the server.
How cookies and adverts work here
We use one first-party cookie for the consent choice and nothing more. Any other cookies come from advertising partners outside our control; they can be blocked or deleted in your browser, and doing so costs the tool nothing, because the calculation is independent of them.
Analytics and aggregate statistics
We watch which of the OvuLivo tools get used, in aggregate, so that effort goes where it is useful. That is the extent of it — no individual profile, and no analytics event ever includes the values you entered.
Sensitive health figures
Health numbers people would rather keep private never reach us. The tool reads them only for the length of the calculation; refresh the page and there is nothing left to recover.
Security and data retention
No personal calculation data is held by us at any point, which makes retention a non-issue for the tool. The site itself is delivered over encrypted connections and kept up to date.
Children's privacy
These tools are meant for a general audience and are not aimed at children under 13. We do not knowingly gather personal information from children; if you believe a child has provided some, contact us and we will remove it.
The rights you have
Privacy law in some regions gives you the right to see, correct, delete or restrict the use of personal data held about you. In practice we hold almost nothing tied to you, since calculator input never reaches us, but any request you make will be taken seriously.
