Safety Boundaries: What DiveOne Is and Isn't

DiveOne is a recreational dive logging and tracking tool. It records depth, time, temperature, and GPS using Apple Watch Ultra hardware sensors. It creates a dive journal automatically. It exports data in standard formats. It works offline. It stores data locally on your device.

DiveOne is not a certified dive computer. It does not calculate decompression limits, no-decompression times, or ascent rates for safety purposes. It does not replace your BCD, regulator, backup air source, or any piece of life-support equipment. It does not provide gas mix analysis, O2 toxicity warnings, or nitrogen loading estimates.

Your primary safety equipment is: certified dive computer, BCD, regulator, backup air source, and your training. DiveOne sits in the secondary category: a logging companion that records your dive alongside your primary gear. Think of it as a dive journal that writes itself — not as safety equipment.

We will never market DiveOne as a dive computer. We will never claim certifications we don't have. We will never interpolate or fabricate sensor data. If a reading is invalid, we mark it as unavailable — we don't guess. Your safety depends on honest tools, and we take that responsibility seriously.
