Deco Captain — Privacy Policy
Effective Date: March 5, 2026
Version: 1.0.0
This Privacy Policy describes how Aquatic Instruments LLC ("Company," "we," "us," or "our"), a Washington State limited liability company, collects, uses, and protects information in connection with the Deco Captain mobile application ("App") and the website located at https://www.decocaptain.com ("Website"). Together, the App and Website are referred to as the "Services."
By using the Services, you agree to the practices described in this Privacy Policy. If you do not agree, please do not use the Services. Your use of the Services is also subject to our Terms of Use, available within the App and at https://www.decocaptain.com/terms-of-use.
1. Overview
Deco Captain is designed with privacy in mind. The App does not require an account or login, does not collect your name or email address through the App, and stores your dive plans and preferences locally on your device. We do not sell, rent, or share your personal information with advertisers, data brokers, or any third party for marketing purposes.
2. Information We Collect
2.1 Information Stored on Your Device
The following data is created and stored locally on your device and is not transmitted to us unless you take an explicit action (such as submitting a bug report or sharing a link):
- Dive plans and profiles — decompression plans, gas configurations, depth/time parameters, and related planning data.
- User preferences and settings — your chosen units, gradient factors, algorithm settings, and other App configuration choices.
This data remains on your device and under your control. If you enable iCloud sync (when available), this data may be synced across your Apple devices through Apple's iCloud/CloudKit service, subject to Apple's privacy policy.
2.2 Analytics and Diagnostics
We collect anonymized analytics and diagnostic data to help us understand how the App is used, identify issues, and improve performance. This may include:
- App usage patterns (e.g., which features are used, session duration)
- Crash reports and diagnostic logs
- Device type, operating system version, and device locale (e.g., en-US)
- App version
This data is collected through Apple's built-in analytics services and may also be collected through third-party analytics and crash reporting services. Analytics data is aggregated and anonymized and cannot be used to identify you personally.
2.3 Information You Choose to Share
- Bug reports — if you submit a bug report, it may include your dive plan data, user preferences, device information, and diagnostic logs to help us reproduce and resolve the issue. Bug reports may also include any information you voluntarily provide in your description of the issue.
- Shareable links — the App allows you to share dive plans and settings with others via a link. When you generate a shareable link, your dive plan data and relevant settings are encoded into the URL itself. Anyone with access to the link can view this data. We do not control how recipients use or share these links.
- Contact form and email — if you contact us through the Website contact form or via email, we collect the information you provide, such as your name, email address, and message content. We use this information solely to respond to your inquiry.
2.4 Website Data
When you visit our Website, our hosting provider may automatically collect standard server log data, including your IP address, browser type, referring page, and pages visited. We do not use cookies for tracking or advertising purposes.
3. How We Use Your Information
We use the information we collect for the following purposes:
- To provide and maintain the Services.
- To improve the App's functionality, performance, and user experience.
- To diagnose and fix bugs, crashes, and technical issues.
- To respond to your inquiries and support requests.
- To comply with legal obligations.
We do not use your information for advertising, profiling, or automated decision-making.
4. How We Share Your Information
We do not sell, rent, or share your personal information with third parties for marketing or advertising purposes.
We may share information in the following limited circumstances:
- Service providers — we may use third-party services for analytics, crash reporting, and hosting that process data on our behalf. These providers are contractually obligated to use your data only to provide their services to us and in accordance with applicable privacy laws.
- Apple — analytics and diagnostic data may be shared with Apple through their built-in services, subject to Apple's privacy policy and your device settings.
- iCloud/CloudKit — if you enable iCloud sync, your dive plan data and settings are synced through Apple's CloudKit service. Apple processes this data in accordance with its privacy policy.
- Legal requirements — we may disclose information if required to do so by law, regulation, or legal process, or if we believe in good faith that disclosure is necessary to protect our rights, your safety, or the safety of others.
- Your choice — when you generate a shareable link or submit a bug report, you are choosing to share your data. We are not responsible for how third parties who receive your shared data use it.
5. Data Retention
- On-device data — dive plans, profiles, and preferences remain on your device until you delete them or uninstall the App.
- iCloud data — synced data is retained in your iCloud account under your control and subject to Apple's data retention practices.
- Analytics and diagnostics — aggregated analytics data is retained for as long as necessary to fulfill the purposes described in this policy.
- Contact form and email correspondence — we retain your communications for as long as necessary to resolve your inquiry and for our records, after which they are deleted or anonymized.
- Bug reports — retained for as long as necessary to diagnose and resolve the reported issue.
6. Data Security
We take reasonable measures to protect the information associated with our Services. On-device data benefits from the security features built into your Apple device, including encryption. However, no method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.
7. Children's Privacy
The App is intended only for individuals who are at least 18 years of age or the age of majority in your jurisdiction, whichever is greater. We do not knowingly collect personal information from children. If we become aware that we have collected personal information from a child, we will take steps to delete it promptly. If you believe a child has provided us with personal information, please contact us at support@aquaticinstruments.com.
