Frequently asked questions
Where is my data stored?
Entries are saved only in your own browser’s local storage on this device — they are never sent to our servers or any third party. Clearing your browser data or using a different device/browser means starting a fresh log. You can export a CSV backup at any time.
How often should I measure?
Most protocols suggest measuring weekly or biweekly, at the same time of day (morning, before eating) with the same technique. Bodies fluctuate daily, so spacing measurements out shows real trends rather than noise.
Why track inches instead of only weight?
Scale weight conflates fat, muscle, water, and glycogen. Circumference measurements often move when the scale doesn’t — especially with strength training — making them a useful complementary progress signal.
