Desktop — 4-week trends with 31 days of sample data
Your health data stays on your device.
Symptom logs, mood records, cycle data — perimenopause tracking involves some of the most sensitive health information you generate.
Fieldnote stores everything in your browser’s local storage — on your device only. Not in the cloud. Not on our servers. Nowhere we, or anyone else, can access it.
The demo and the purchased file work identically. Neither sends anything anywhere. Your data is yours in the fullest sense.
Export a backup file at any time. Import it on a new device. Share it with your doctor by email or print the report. You decide what happens to your data and where it goes.
Questions
FAQ
Can I try it before buying?
Yes. The demo at fieldnote.health/demo/menopause is pre-loaded with 31 days of sample symptom data — hot flashes, night sweats, mood shifts, sleep check-ins — so you can see exactly what the app tracks and what the appointment report looks like. You can also log up to 5 events or check-ins of your own to try it. The full version is unlimited.
What stages of menopause does it support?
Perimenopause, menopause, and postmenopause. The Settings panel lets you set your stage, which adjusts which fields appear (cycle-related fields are hidden in postmenopause).
Does my data stay private?
Completely. Everything is stored on your device only. Nothing is ever transmitted. This is true for the demo and the purchased file — both work identically.
How does the appointment report work?
The Report tab aggregates your logged data — hot flash frequency, sleep averages, mood trends, trigger patterns — and generates a summary with suggested questions for your clinician. You can print it directly from the app.
Can I use it on multiple devices?
Yes. Export a backup file from one device, import it on the other. No automatic syncing — there's no server involved.
What format is the backup file?
An industry-standard format (JSON) that any version of the app can read. Plain text — you can open it, read it, and keep it independently of Fieldnote.
