Privacy Policy

Effective 9 November 2026

Who we are

DepthPilot is an app for Apple Watch Ultra and iPhone, published by Hampson Labs Limited (“we”, “us”), a company registered in England and Wales with company number 17570811. If you have a question about this policy, contact us at support@hampsonlabs.co.uk.

Data the app uses, and where it stays

DepthPilot needs some personal data to work as a dive computer and logbook. All of it is processed and stored on your devices. None of it is sent to us.

Data	Why it is used	Where it stays
Dive data (depth, time, water temperature, ascent rate, decompression and gas information, dive profile)	To run the dive computer and keep your dive log.	On your Apple Watch and iPhone.
Heart rate (Apple Health)	To show your heart rate during a dive and record it with the dive. With your permission the Watch also saves each dive as a workout in Apple Health.	On your devices and in Apple Health. Never used for advertising or shared with anyone.
Location	To record where a dive starts and ends, to show your position on the map, and to guide you to a dive site.	On your devices. Only collected while you use these features.
Your profile, certifications, equipment and emergency contacts	Information you choose to enter, such as certification cards and the contacts for a dive notice.	On your iPhone.
Purchases	To unlock DepthPilot Pro.	Handled by Apple. We do not receive your payment details.

Your iPhone and Apple Watch exchange this data directly with each other (through Apple's WatchConnectivity) so your dives appear in the iPhone log.

Permissions

DepthPilot asks for access to Health (heart rate and workouts) and Location. Both are optional: without them the app still works, but without heart rate or dive positions. You can change these permissions at any time in the Health app (Sharing → Apps), in iPhone Settings, and in the Watch's Settings → Privacy & Security.

Online services the app connects to

To show maps and dive sites, the app connects to these services. They receive what any website receives when you load it (such as your IP address and the area of the map being viewed), but no personal data from DepthPilot:

• OpenDiveMap (api.opendivemap.com): to download the public database of dive sites.
• OpenFreeMap (tiles.openfreemap.org): for map images.
• Apple: for Apple Maps, directions, and App Store purchases. Apple's use of data is covered by Apple's Privacy Policy.

Sharing that you choose

When you choose to share something, for example a dive report PDF, a dive-site position, a certificate or a dive notice to your contacts, it goes through the iOS share sheet or Messages to the people and apps you pick. We do not see it.

Backups

A DepthPilot backup is a file you create and save where you choose (for example Files or iCloud Drive). Your device's own iCloud or computer backups may also include the app's data, under Apple's terms.

Keeping and deleting your data

Your data stays on your devices until you delete it. You can delete individual dives in the app, and deleting DepthPilot from your iPhone and Apple Watch removes everything the app stored on them. Data saved to Apple Health stays there until you remove it in the Health app.

Children

DepthPilot is intended for trained and certified divers. It is not directed at children, and we do not knowingly collect data from anyone.

Your rights

Because we do not hold your personal data, there is nothing for us to access, correct or delete. Your data is under your control on your devices. If you are in the UK or EU you have rights under data protection law (UK GDPR / GDPR), and you can contact us or your local data protection authority (in the UK, the Information Commissioner's Office) with any concern.

Changes to this policy

If we change how DepthPilot handles data, we will update this page and the date at the top before the change takes effect.
