Frequently asked questions

Which formulas are used to estimate BMR?

We implement the Mifflin-St Jeor and Harris-Benedict formulas to yield highly reliable baseline metabolic calculations.

Is my health data saved on your servers?

No. Toolskyt does not record body dimensions, dietary inputs, or medical parameters. All metrics run locally.

Does the Sleep Calculator count cycles?

Yes, it plans ideal wakeup or sleep-onset times centered around standard 90-minute sleep cycles to minimize grogginess.
