Privacy Policy
Last Updated on September 3, 2026
We respect your privacy and are committed to protecting it through our compliance with this privacy policy (“Policy”). This Policy describes the types of information we may collect from you or that you may provide (“Personal Information”) on the underwaterly.com website (“Website” or “Service”) and any of its related products and services (collectively, “Services”), and our practices for collecting, using, maintaining, protecting, and disclosing that Personal Information. It also describes the choices available to you regarding our use of your Personal Information and how you can access and update it.
This Policy is a legally binding agreement between you (“User”, “you” or “your”) and Underwaterly (“Underwaterly”, “we”, “us” or “our”). If you are entering into this agreement on behalf of a business or other legal entity, you represent that you have the authority to bind such entity to this agreement, in which case the terms “User”, “you” or “your” shall refer to such entity. If you do not have such authority, or if you do not agree with the terms of this agreement, you must not accept this agreement and may not access and use the Website and Services. By accessing and using the Website and Services, you acknowledge that you have read, understood, and agree to be bound by the terms of this Policy. This Policy does not apply to the practices of companies that we do not own or control, or to individuals that we do not employ or manage.

Automatic collection of information
When you open the Website, our servers automatically record information that your browser sends. This data may include information such as your device’s IP address, browser type, and version, operating system type and version, language preferences or the webpage you were visiting before you came to the Website and Services, pages of the Website and Services that you visit, the time spent on those pages, information you search for on the Website, access times and dates, and other statistics.
Information collected automatically is used only to identify potential cases of abuse and establish statistical information regarding the usage and traffic of the Website and Services. This statistical information is not otherwise aggregated in such a way that would identify any particular User of the system.
Information We Collect
When you create an account on Underwaterly, we may collect the following types of information:
Your name and contact details
Profile information and preferences
Dive logs and dive-related data
Location information (if you choose to provide it)
Sign in with Google
We let you register and log in to Underwaterly using your Google account ("Sign in with Google"), provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland ("Google").
To be able to offer this option, our app loads a program from Google (Google Identity Services) when you open it. Loading it transmits technical data to Google - in particular your IP address, information about your browser and operating system, and the address of the page you are viewing - before and regardless of whether you actually use the option. Without it, the "Sign in with Google" button cannot be displayed. This processing is based on our legitimate interest in offering an established and secure sign-in method alongside email and password (Art. 6(1)(f) GDPR). We do not use Google's "One Tap" sign-in prompt.
If you then select "Sign in with Google", Google transmits your name and email address to us so we can create and authenticate your Underwaterly account. This further processing is based on your consent (Art. 6(1)(a) GDPR), given by actively selecting "Sign in with Google". You can withdraw this consent at any time with effect for the future, without affecting the lawfulness of the processing carried out before the withdrawal.
Google may process this data in the United States. Google participates in the EU-U.S. Data Privacy Framework and/or relies on Standard Contractual Clauses as a safeguard for such transfers; see policies.google.com/privacy for details.
You can also create an Underwaterly account with just an email address and password, without using Google Sign-In.
