Cycle journal
the period diary that writes itself.
Every period tracker hands you a form: rate the mood, tap the symptoms, every single day. Everblue is a small pet cloud named Cloudy who keeps the diary for you — your sleep, your steps, your songs, and, if you switch the lens on, where you are in your month. You live. He writes.

How the cycle lens works
One switch. Two numbers. Zero logging.
No symptom checklists, no daily check-in, nothing to remember. The lens adds one line of context to a diary that was already writing itself.
Flip one switch
The cycle lens is off by default, like every signal. It has its own Apple Health switch, separate from sleep and steps — Cloudy reads nothing about your cycle until you turn it on.
Your phone does the math
From Apple Health, on your device, Everblue derives exactly two things: a day number and a phase label — like “day 24, luteal.” Your dates and flow never leave your phone.
Entries get context
Cloudy weaves that day and phase into the entries he already writes about your sleep, your steps, your songs. A short night on day 24 reads differently than one on day 8 — and now the diary knows.
And what it deliberately isn’t: Everblue doesn’t predict your period, score your days, or forecast how you’ll feel. It isn’t a medical app at all. It writes down what actually happened — which turns out to be the part every tracker left up to you.
What a month reads like
Same cloud, different days.
Entries stay short, dry, and observational — Cloudy notes what the day held, never what the next one will. The day and phase are just there, the way a date is.
heating pad, the couch, one episode that turned into four. a quiet day. i kept the entry quiet too.
long walk, loud playlist, eleven thousand steps. whatever gear this is, you found it today.
short fuse, short night, same three songs as last month around now. not saying it’s a pattern. just the one writing it down.
The two-cycle payoff
A record you can bring to an appointment.
Anyone who’s been asked “and how long has this been happening?” knows the blank. A diary written at the time — not remembered after — answers it.
Month one
The entries pile up on their own — sleep, mood, movement, with the day and phase attached. You logged nothing.
Month two
The rhymes show up. The short nights that cluster, the playlist that comes back around day 26 — written down twice now, both times in the moment.
The appointment
When you want to talk to a doctor about your month, you’re not reconstructing it from memory in a waiting room. You bring a daily record that was written as it happened.
Cycle privacy, specifically
Your cycle is nobody’s business. Including ours.
Off by default.
Cycle reading is its own Apple Health switch, separate from every other signal. Nothing about your cycle is read until you flip it — and you can flip it back off anytime.
Dates and flow stay put.
Your raw cycle data stays on your device. At most, a derived day number and phase label — “day 24, luteal” — rides along while an entry is being written.
Never stored on a server.
That derived number is used transiently to write the entry and is never stored server-side. The journal itself lives on your phone, not with us.
No account, no profile.
There’s no login and no identity to attach a cycle to. No ads, no selling your data — the same rules as the rest of Everblue.
The privacy policy spells all of this out in plain language — per-category health switches, what rides an entry request, and what never leaves your device.
Your month, written down.
