Freediving is beautiful, powerful, and dangerous.

Core Safety Position

Freediving and breath-hold activities can cause serious injury or death. Blackout, loss of motor control, drowning, barotrauma, decompression-related injury, panic, entanglement, environmental hazards, marine life, boats, currents, weather, and medical conditions can create severe or fatal risk.

Never freedive or practice breath holds alone. Avoid hyperventilation before breath holding. Blackout can occur on land or in shallow water. Always use qualified safety support, appropriate supervision, conservative planning, and training from qualified professionals. Depth is a software platform for athlete profiles and records; it is not a substitute for instruction, judgment, emergency preparation, or medical advice.

What Depth Does Not Do

Timers, O2/CO2 tables, goals, and voice prompts do not measure oxygen or carbon dioxide, detect blackout, monitor you, or summon help. Defaults and labels are not individualized recommendations or safe limits. Devices, browser timing, and audio can fail or be delayed, including when a tab is backgrounded or a device sleeps. Never prolong a breath hold while waiting for an alert.

Pressure and Boyle's-law lung-volume illustrations use simplified assumptions. They are not physiological predictions, a dive computer, or tools for decompression or gas planning. Email verification does not establish identity, qualifications, fitness, or the validity of a record or certificate. Comparisons and personal bests are not targets you should attempt.

Depth does not certify that a dive was safe, that an athlete is fit to dive, that a record should be attempted, that a training plan is appropriate, or that a location is safe. Public profiles, logs, records, charts, media, or Depth Cards provide profile and performance information only.

Do not use Depth to decide whether you or another person should freedive, train, compete, supervise, rescue, or participate in breath-hold activity.

Privacy And Locations

Dive locations can reveal routines, private sites, travel patterns, and safety context. Profiles start with private visibility, but profile names, usernames, and uploaded profile and hero images remain public. Dive records follow the available visibility settings. Athletes should publish only information they are comfortable making public.

Emergency Boundary

Depth is not monitored as an emergency service. If someone may be injured, missing, in distress, or in immediate danger, contact local emergency services and qualified rescue resources immediately.
