Calculator inputs

Calculations happen in your browser. The website code does not send your weight, age, meals, symptoms or schedule to a server. Inputs generally disappear when you reload, except for the headache and stress check-in diaries.

Headache diary

Diary dates, severity and notes are stored in localStorage on this browser and device. They are not encrypted by this website, backed up or synced. Anyone with access to this browser profile may be able to view them. Use Export CSV to keep a copy, Delete to remove an entry, or Clear log to remove all entries.

Stress check-in diary

Only when you choose Save, your date, self-rated stress, optional mood, selected contexts and note are saved in this browser’s localStorage. They are not encrypted, backed up or synced. Shared browser profiles may expose them to other people. Export CSV, delete individual entries, or clear the diary from the Stress & Calm tool. Unsaved form inputs and exercise progress are not retained after reload. Storage errors are reported; private browsing or browser settings may prevent saving.

Preferences and external services

Your color-theme preference is stored locally. Fonts use the device’s installed fonts. Visiting source links opens external services with their own policies. The hosting provider processes connection information needed to deliver the website; this page does not make claims about the provider’s retention practices.

Clearing data

Use the diary’s clear control or remove this site’s data in browser settings. Clearing browser data can permanently remove your diary. Printed or exported copies must be managed separately.
