Terms of use

Short plain-English terms for using Kairox.

Safety

Kairox is a workout timer and cueing tool only. It does not provide medical, fitness, physiotherapy, injury-prevention, or coaching advice.

  • Choose workouts appropriate to your ability and environment.
  • Warm up, use safe form, and train within your limits.
  • Stop training and seek appropriate help if you feel pain, dizziness, chest pain, faintness, or any unsafe symptom.

Acceptable use

Use Kairox as a personal workout timer and cueing tool. Don't try to break, abuse, scrape, reverse-engineer, or interfere with the service, and don't use it to harm others or circumvent paid features.

Your account

You can use Kairox anonymously for core timer features. If you create an account, you're responsible for keeping your login credentials safe and for activity on your account. Let us know via Support if you think your account is being misused.

Kairox Pro and billing

Kairox Pro is a paid subscription billed through Stripe at the prices shown in the app at checkout. Subscriptions renew automatically until cancelled.

You can cancel anytime through Billing, which opens the Stripe Customer Portal. See the Refunds page for refund-request guidance.

Free features may change over time. Pro features may be added, improved, or adjusted. We'll avoid removing core paid functionality you rely on without a reasonable alternative.

Device-dependent features

Some Kairox features depend on your browser, operating system, and device. These include:

  • Voice commands (microphone access, speech recognition support).
  • Wake Lock (keeping the screen on during a workout).
  • Install behaviour as a Progressive Web App and offline use.
  • Spoken cues using your device's speech voices.

These features may be unavailable, limited, or behave differently depending on your device. The core timer is designed to work even when they aren't available.

Changes to Kairox

Kairox is actively developed. Features, copy, presets, the exercise library, pricing, and these terms may change over time. Material changes will be reflected in the in-app legal pages.

Safety and responsibility

You are responsible for training safely. Kairox is not responsible for injuries or harm caused by exercise misuse, unsafe training, poor form, ignoring symptoms from your body, unsuitable workout choices, or unsuitable training environments.

If you have a medical condition or are unsure whether an activity is safe for you, consult an appropriate professional before training.

No warranty

Kairox is provided as-is and as-available. We don't warrant that it will be uninterrupted, error-free, or compatible with every device.
