Terms of Service

Placeholder. Zyra's full terms of service have not been published yet. They are being prepared and will appear on this page before Zyra Workouts launches publicly. Nothing here is hidden fine print — there simply are no published terms yet, and we would rather say that than paste boilerplate.

Until then, two commitments already stand and are documented in the privacy policy: your data is yours (local-first, optional sync, in-app deletion), and it is never sold or used for advertising.

Estimates and reference material

The calculators on this site compute estimates from values you enter, using published formulas and the apps' own rules — a population equation for energy expenditure, a rep-count formula for estimated one-rep max, the app's landmarks for weekly sets. The reference pages (exercises, muscle groups, programs, glossary, articles) describe how those formulas and the apps' catalog work. All of it is educational approximation, not measurement: a calorie estimate is typically 100–200 kcal from a measured value and can be off by more, and a rep-based 1RM estimate is not a tested lift.

None of it is medical advice, a diagnosis, or an individual prescription, and it must not be relied on for medical decisions. Zyra is a training and nutrition tracking tool, not a medical device or a medical service: it does not diagnose or treat any condition, and the program pages are generated templates, not prescriptions. Decisions about your health belong with you and a qualified professional who knows your history; decisions about your training with you and a coach. Full disclaimer: Zyra is a training and nutrition tracking tool. Nothing on this page is medical advice, a diagnosis, or an individual prescription. The numbers are estimates from published formulas and the apps' own rules — consult a qualified professional for decisions about your health, and a coach for your training.
