Frequently asked questions
Is this weight tracker really private?+
Yes. Every entry you log stays in your browser's localStorage. Nothing is sent to our servers. Clear your browser data and the entries are gone.
Can I use this on multiple devices?+
Not directly — the data stays on the device where you logged it. But you can export a JSON file from one device and import it on another to move your history.
How often should I weigh myself?+
For tracking trends, daily weigh-ins at the same time of day (ideally first thing in the morning, after the toilet) give the most signal. A single day can vary by 1–2 kg; it's the 7-day average that matters.
Will my entries survive a browser update?+
Yes, localStorage persists across browser restarts and updates. It's cleared if you explicitly clear browsing data, or if the browser decides to evict storage (rare). Export a backup every few months to be safe.
