Frequently asked questions
- Where is my weight data stored?
- Entries stay in your browser's local storage on this device. Nothing is uploaded to our servers and no account is required.
- Can I export my weight history?
- Yes. Use Export CSV to download date, weight in kg and lbs, and BMI columns for spreadsheets or backup.
- How is BMI calculated?
- When you save your height under Goals & Height, BMI uses the standard formula: weight in kg divided by height in meters squared.

- No. Weight entries and settings stay in your browser on this device only — we never receive or store them.
