Learn to read your own cycle.
Thirty seconds each morning: your waking temperature, and what you notice. Within a cycle or two the pattern is on the page, and you can read it yourself.
It stays yours.
Your chart is saved on your device, not on our servers. Sync and mentor sharing exist, and both stay off until you turn them on. Export it or delete it whenever you want. Years from now it is still your record, and still yours to read.
You can read it yourself.
The coverline, the temperature shift, the fertile window: every mark on your chart comes from a written rule, so you can always find out why it landed where it did. See how the math works.
You can learn it with someone.
Connect with a fertility awareness educator when you want help reading a cycle. You choose which charts they see, and nothing reaches them until you send it.
Educational tracking only, not medical advice and not a contraceptive. .
