Product positioning

Free, privacy-first period calculator at period-calculator.net, designed mainly for mobile.

Core calculation (Version A)

Completed

Enter last period start, bleed length, and cycle length โ†’ get predicted next period, ovulation, and fertile window.

Local-only privacy

Completed

All calculations run in your browser, with no account, no tracking, and no data sent to our servers.

Results page messaging

Completed

We tell you which phase you're likely in today (period, fertile window, ovulation, PMS phase) and what that usually feels like.

Irregular cycle warning

Completed

If you enter <21d or >35d cycles, you get a gentle note: one odd cycle can be normal, but if it happens a lot, talk to a clinician.

Educational content / blog

Completed

We're publishing cycle health explainers (fertile days, PMS, "safe days," etc.) with medical disclaimers and references.

Multi-language copy

Completed

Full site text is ready in English, German, Spanish, Portuguese, and Chinese, with locally natural keywords (e.g. "Periodenrechner," "calculadora del perรญodo," "calculadora do perรญodo").

Visual identity

Completed

We use a soft heart-style logo, pink for period days, green for ovulation/fertile days, and a single-month calendar with emoji legend.

Phase / Fertility card

Completed

The results page will include a card that says "You're likely in [phase] right now" plus caring guidance for comfort, conception, or contraception.

Trust pages

Completed

We're adding /privacy, /terms, and /roadmap to clearly state our privacy promise, medical disclaimer, and why we built this tool.

In Progress

Homepage cleanup

In Progress

We're improving typography, spacing, and sections ("Why tracking matters," "Privacy," "Who this is for") so the page doesn't look like one block of text.

"What this day means" on calendar

In Progress

Each calendar day will be tappable and will explain why it's marked (period, high fertility, etc.) and what that means for you today.

Blog preview on homepage

In Progress

The homepage will show a "Latest from the blog" strip to prove the site is alive and improving.

hreflang & language switching

In Progress

We're wiring up proper language switching and SEO tags so global users get the site in their own language.

Planned

Advanced mode (irregular cycles)

Planned

We plan an "Advanced mode" to enter multiple past periods, estimate your personal average/variability, and support less regular cycles.

Monetization

Planned

We plan to add lightweight, respectful ads after content volume is higher, without selling or sharing menstrual data.
