Terms of use

Last updated: 10 November 2026

This is a translation. The Dutch text is the one that is legally binding: read it in Dutch.

These terms apply to the use of Nextdive (the website nextdive.app and the apps), offered by Spectes, Dina Appeldoornlaan 52, 1421 TD Uithoorn (Chamber of Commerce (KvK) no. 42205042), reachable at info@nextdive.app. By creating an account you agree to them. How we handle your data is described in the privacy policy. For clubs, the club terms and the data processing agreement apply as well.

1. Your account

• You are at least 16 years old, or you use Nextdive with the permission of a parent or guardian.
• An account is personal. You keep your sign-in details secret and are responsible for what happens with your account.
• You can delete your account yourself at any time in your settings.

2. Nextdive is not a safety tool

Nextdive is meant for recording dives, looking back on them and preparing them. It never replaces your dive computer, your training, your certification limits or the judgement of your instructor. Warnings in the app (for example about depth compared to your certification) are only a reminder and may be incomplete or wrong. Imported data may differ from what your dive computer measured, so check it yourself.

3. The dive planner

• The dive planner is a planning aid, not a dive computer. It calculates a plan with a decompression model (Bühlmann ZHL-16C with gradient factors) from what you enter. Its results are model results: they may be wrong, and no model can guarantee that a dive is safe, whatever the plan says.
• A plan assumes a first dive of the day at sea level, with no altitude and no earlier dives, and knows nothing of the actual dive, your health or the conditions.
• Always dive with your own dive computer, and within your training, your certification and the gas you carry. Decompression dives and dives on helium or rich mixes need the training for them; don't plan a dive you aren't trained for.
• Before you first use the planner, you confirm that you understand this and use it at your own risk. We keep that you did, and when. If these points change in substance, we ask you again.
• We check the planner's calculations against an independent implementation of the same model, but give no guarantee that it is free of errors.

4. Your data and content

• What you put in Nextdive (dives, notes, photos) stays yours. You only give us the right to store, process and show it as far as needed to make Nextdive work, for example to buddies you tag or to your club.
• You are responsible for what you write about others, such as buddy names and notes. Do not add anything that is unlawful or offensive, or that you may not share.
• You can always export your dives as CSV. Make a copy now and then: we do our best, but cannot guarantee that data is never lost.

5. Buddies and clubs

• A dive on which you tag someone is visible to that buddy, who can copy it to their own logbook.
• Agreements about taking part, prices, rental, payment, courses and liability during dives are made with the club, not with Nextdive. Nextdive is not a party to them.
• What a club keeps about you (membership, sign-ups, lessons, notes) Nextdive processes on behalf of that club. The club is responsible for it; see the privacy policy.

6. Connections with Garmin, Suunto and other services

• Connections with third-party services are optional and work through their APIs. Those services may change, limit or stop their API at any time, so a connection may stop working temporarily or for good. Importing files always remains possible.
• Your use of Garmin Connect and Suunto remains subject to their own terms.
• Garmin, Garmin Connect, Descent and Suunto are trademarks of their owners. That Nextdive can connect with them does not mean they recommend or endorse Nextdive.

7. What is not allowed, and reporting

• Abusing Nextdive, such as: trying to sign in to someone else's account, collecting other users' data (scraping), overloading the service, circumventing security, or posting content that is unlawful or infringes the rights of others.
• Do you see content on Nextdive that you believe is unlawful, for example on a public profile? Report it to info@nextdive.app, with a link and an explanation of why. We handle every report with care and let you know what we do about it.
• In case of abuse or unlawful content we may remove content or block or delete your account. We tell you why, unless the law forbids it, and you can object at the same address. We moderate by hand, not automatically.
• That address is also the point of contact for users and authorities under the Digital Services Act, in Dutch or English.

8. Availability and changes to the service

We aim for Nextdive to always work, but cannot guarantee it. Maintenance, outages or changes at service providers can make the service temporarily unavailable. We may add, change or stop features. If Nextdive shuts down entirely, or we end your account for a reason other than abuse, we announce it at least 30 days in advance so you can export your dives.

9. Costs

• The logbook is free. Features you use for free now never become paid retroactively.
• You can try Nextdive Pro for free once, for a month. That month ends by itself; you pay nothing and what you added stays.
• Your club can give you Nextdive Pro. The club pays for it, under the club terms. If the club stops, your Pro stops; what you added stays.
• You can buy Nextdive Pro in the app, per month or per year, through Google Play or the App Store. The store sells it to you: price (VAT included), payment, cancellation and refunds follow the store's terms. The subscription renews itself until you cancel it in the store, at least 24 hours before the end of a period; Pro then runs until that end. Deleting your Nextdive account does not cancel it.
• If paid features or subscriptions for divers themselves are introduced, price, term, cancellation and right of withdrawal are stated clearly beforehand. You only agree to them when you sign up for them yourself.

10. Intellectual property

• The software, the name Nextdive, the logo and the design belong to Spectes or its licensors. You get a personal, non-transferable right to use Nextdive under these terms.
• You may not copy, sell or reverse engineer Nextdive, except as far as the law allows.
• Ideas and feedback you send us we may use freely, without compensation.

11. Liability

• Nextdive is provided as is. We are not liable for damage caused by using (data from) Nextdive, for decisions you make above or under water, for plans made with the dive planner (section 3), or for connections with third parties that stop working.
• Where we are liable, it is limited to the amount you paid Nextdive in the 12 months before, or €50 if you paid nothing.
• These limits do not apply in case of intent or gross negligence, not to damage from death or personal injury that is our fault, and not as far as the law (such as the rules on product liability) does not allow them. They do not affect your rights as a consumer.
• We are not liable for failures caused by force majeure, such as outages at hosting, e-mail, payment or connected services, or on the internet.

12. Changes to these terms

We may change these terms. We announce important changes at least 30 days in advance in the app or by e-mail. If they change in substance to your disadvantage, you can export your data and delete your account before they take effect. We keep which version you agreed to, and when.

13. Language, applicable law and disputes

The Dutch text of these terms is binding; translations are for convenience. These terms are governed by Dutch law. If you are a consumer in another EU country, you keep the protection the law of your country of residence gives you, and you can also go to court there. We first try to resolve disputes together; contact us at the address above.
