Support

We're a small team building dive tools we'd want to use ourselves, and we read every message that lands in our inbox. If something in Deco Captain isn't working the way you'd expect, you've spotted a rough edge, or you just have a question about how a feature behaves on a particular dive profile, please get in touch.

We typically reply within a couple of business days. Replies can take a little longer on weekends and around holidays, but no message goes unread.

Reporting a Bug

The fastest way to report a bug is the Send Feedback button inside the app — it opens a pre-addressed email and automatically attaches a diagnostic snapshot, so we already know your device, your Deco Captain version, and the relevant app state without you having to dig any of it up. Just describe what happened and send it off. A short note covering the following usually points us straight at the cause:

• What you were doing when it happened — the dive parameters, the screen you were on, and what you tapped just before the issue showed up.
• What you expected to happen, and what actually happened.
• A screenshot or short screen recording, if it's something visual.

Feature Requests and Feedback

Thoughtful feedback from divers is one of the best inputs we get for shaping where the app goes next. If there's a planning workflow or a piece of decompression theory you wish the app handled differently, we want to hear about it. Tell us what you're trying to plan and why, and we'll take it from there.

Account and Data Questions

Deco Captain runs entirely on your device — your dive plans belong to you and never leave your iPhone unless you explicitly share one. If you have a question about how a particular feature handles your data, or you'd like help retrieving or removing information, send us an email and we'll walk through it with you. For the full picture, our Privacy Policy covers what data the app touches and how it's used.
