FAQ
Does this tool keep my data private?
Yes. Entries are stored locally in your browser using IndexedDB. Nothing is uploaded unless you choose to export the JSON file.
Can I track more than one symptom in a day?
Yes. You can add multiple entries for the same day and time, then filter them later by symptom name, severity, date range, or tags.
Why use tags?
Tags help spot patterns faster. Use presets like headache or fatigue, then add custom tags such as travel, dehydration, or work stress.
