Effective Date: October 10, 2026

These Terms of Use govern your use of DiveCheck by Kraken DiveWorks (“DiveCheck,” “the App”), published by Kraken DiveWorks, LLC, 3318C Berlin Tpke, Newington, CT 06111 (“Kraken DiveWorks,” “we,” “us”). By installing or using the App you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the App.

Safety: a reference tool only

DiveCheck is a record-keeping and reference tool. It is not a dive computer, not a decompression-planning system, and not a substitute for training from a certified instructor. Checklists, calculators (including the gas-blending calculator), reminders, imported dive data and any other information in the App may be incomplete, out of date or wrong. Always verify against a certified dive computer, an analyzed fill and your training, and always dive within your training and certification. Diving, and especially technical diving, rebreather diving and gas blending, carries a serious risk of injury or death. You are solely responsible for your own safety and decisions. Never dive a gas you have not personally analyzed.

License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your own diving records. You may not copy, modify, rent, resell or reverse engineer the App, or use it to build a competing product, except as the law allows. If you download the App from the Apple App Store, Apple’s standard Licensed Application End User License Agreement also applies. Apple and Google are not responsible for the App or for supporting it.

Subscriptions

• DiveCheck requires a subscription. Plans are monthly or yearly, and the price for your country is shown in the App and in the store before you subscribe. A new subscriber’s first period may be a 7-day free trial, where one is offered.
• Payment is charged to your Apple ID or Google Play account when you confirm the purchase, or when any free trial ends. The subscription renews automatically at the same length and price unless you cancel at least 24 hours before the end of the current period.
• Manage or cancel at any time in your App Store or Google Play subscription settings. Deleting the App, or your DiveCheck account, does not cancel a subscription.
• Purchases, billing and refunds are handled by Apple or Google under their own policies. We cannot refund a store purchase directly.
• Prices can change. Where the law or the store requires, you will be told in advance, and a change applies from your next renewal.

Your account

To subscribe, or to use a subscription, you sign in with a Google, Apple or Microsoft account, and you are responsible for keeping it secure. You can link several sign-ins so that one subscription covers them, and you can delete your DiveCheck account in the App (Settings > Danger Zone > Delete my account). Where a version of the App cannot sell subscriptions (for example the desktop versions), sign in with an account that already has one.

Your data

The dive logs, equipment records, certifications, Medical ID and other content you enter stay on your device, and in your own cloud account if you turn on backup. We do not have access to them. You are responsible for keeping your own backups and for the accuracy of what you enter. The Privacy Policy explains the rest.

Acceptable use

Do not misuse the App or our services: do not try to gain unauthorized access, interfere with their operation, or use them to break the law or infringe anyone’s rights.

Third-party names

Product and company names mentioned in the App or in its store listings, such as dive computer, rebreather and training agency names, belong to their owners and are used only to identify what DiveCheck works with. DiveCheck is independent and is not affiliated with or endorsed by them. More detail is under Settings > About > Legal, Safety & Trademarks in the App.

No warranty

To the extent the law allows, the App is provided “as is” and “as available”, without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose and non-infringement.

Limit of liability

To the extent the law allows, Kraken DiveWorks, LLC and its owners, employees and contractors are not liable for any indirect, incidental, special, consequential or punitive damages, or for any injury, illness, decompression sickness, oxygen toxicity, death, loss of data or other harm arising from your use of the App, your inability to use it, or your reliance on information in it. Our total liability for any claim relating to the App is limited to the amount you paid for the subscription in the 12 months before the claim. Some places do not allow these limits; where that is so they apply only as far as the law permits. Nothing in these Terms limits liability that cannot be limited by law, or your mandatory consumer rights.

Ending your use, and changes

You can stop using the App at any time. We may suspend or end access if you break these Terms. We may update these Terms as the App changes; material changes will be posted here with a new effective date, and continuing to use the App means you accept them.

Governing law

These Terms are governed by the laws of the State of Connecticut, USA, without regard to its conflict-of-law rules. Disputes will be brought in the state or federal courts located in Connecticut, except where the law of your country gives you the right to bring a claim where you live.
