Help
Do I need an account?
No. There is no account, sign-in or registration.
Where are my entries kept?
By default, only on the page you are using (session only). If you choose “Save on this device”, they are kept in this browser on this site. They do not sync to other browsers or devices.
Can I lose my records?
Yes. Clearing browser or site data, private browsing or storage clean-up by the browser can delete them. Keep an export if you need a copy.
I share this device. What should I do?
Stay in session-only mode, use your device lock, and delete app data from My records when you finish.
What about calendar reminders?
Calendar files you download are handled by your own calendar app and may be synced by your calendar provider. Changing something here does not update them.
Are these medical tools?
No. They are educational estimates and personal logs. They are not a diagnosis, emergency monitoring or a replacement for maternity or medical care.
How do I move my records to another device?
Download a JSON backup from My records, then import it on the other device. Nothing syncs automatically.
Does sharing a tool share my data?
No. Share the tool’s link only. Links never contain your entries.
Urgent help
These tools are not an emergency service. If you think it may be life-threatening, call your local emergency number. If you are pregnant or have recently given birth and are worried, contact your midwife, maternity unit or doctor now.
