PassageMail Weather

PCN, LLC ("PassageMail," "we," "us," or "our") operates the PassageMail Weather service, including the iOS app, Android app, and Thunderbird extension (collectively, the "Service"). This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.

By using the Service you agree to the practices described in this policy. If you do not agree, please discontinue use of the Service.

1. Information We Collect

1.1 Account Information

When you purchase a subscription and create an account, we collect:

• Your purchase email address (used at checkout)
• Your PassageMail email address (@passagemail.com — chosen by you during account setup)
• Your name (first and last)
• Your license key (generated at purchase)
• Payment information — processed by our payment provider; we do not store full payment card details

1.2 Device Information

When you activate the Service on a device, we record:

• A device identifier (used to enforce the per-license device limit)
• Device platform (iOS, Android, or Thunderbird)
• Device name (if provided)
• Activation date and last-seen timestamp

1.3 Email and Weather Data

The Service sends and receives email on your behalf through your @passagemail.com mailbox:

• Outbound: FTPmail requests to NOAA (NWS.FTPMail.OPS@noaa.gov) — these are plain-text weather data requests containing no personal information
• Inbound: NOAA weather chart responses delivered to your @passagemail.com inbox
• Email content is stored on our mail server and accessible only by you via your credentials
• We do not read, analyze, or share your email content

1.4 Settings and Preferences

If you use the Backup feature, we store a compressed copy of your app settings on our server, including:

• Your selected voyage presets and custom presets
• Your scheduled chart request configuration
• Your link speed preference and bandwidth calibration data
• Your chart queue

Settings backups are associated with your @passagemail.com address and are only accessible by you.

1.5 Usage and Technical Data

We may collect limited technical data to operate and improve the Service:

• License validation requests (timestamp, IP address, platform)
• API request logs (for rate limiting and abuse prevention) — retained for 30 days
• Crash reports submitted through TestFlight or the App Store (iOS) or Google Play (Android)

We do not use third-party analytics SDKs, advertising networks, or tracking pixels in the Service.

2. How We Use Your Information

Purpose	Data Used
Provide the Service — deliver weather charts, manage your account	Account info, email, settings
License validation and device limit enforcement	License key, device ID, @passagemail.com email
Scheduled automatic chart requests (server-side)	Schedule config, @passagemail.com identity
Settings backup and cross-device restore	Preferences, presets, schedule
Customer support and troubleshooting	Account info, API logs
Service security — fraud prevention, abuse detection	IP address, license key, device ID
Transactional email — welcome email, license confirmation	Purchase email, @passagemail.com address

We do not sell your personal information. We do not use your data for advertising purposes.

3. Satellite and Low-Bandwidth Operation

PassageMail Weather is designed for use over satellite connections including Iridium GO! and similar low-bandwidth links. In satellite mode:

• The Service uses HTTP (unencrypted) as a fallback when HTTPS connections fail on high-latency satellite links. This applies only to API calls to our servers — your @passagemail.com email credentials are never transmitted over plain HTTP.
• All data transmitted over satellite is compressed to minimize airtime costs.
• We do not log or retain the content of weather chart requests beyond what is necessary for delivery.

4. Data Sharing and Third Parties

4.1 NOAA / National Weather Service

Weather chart requests are sent to NOAA's FTPmail service (NWS.FTPMail.OPS@noaa.gov) on your behalf. These requests contain only your @passagemail.com address and the names of the weather products you requested. NOAA's use of this data is governed by their own policies.

4.2 Payment Processor

Subscription purchases are processed by a third-party payment provider. We receive confirmation of successful payment and your purchase email — we do not receive or store your full payment card details.

4.3 App Distribution Platforms

The iOS app is distributed via Apple's App Store and TestFlight. The Android app is distributed via Google Play. These platforms may collect their own usage data per their respective privacy policies. The Thunderbird extension is distributed via Mozilla's Add-ons site (addons.mozilla.org).

4.4 No Other Third-Party Sharing

We do not share your personal information with any other third parties except as required by law or to protect the rights and safety of our users.

5. Data Storage and Security

Your data is stored on servers operated by PCN, LLC located in the United States:

• Web and e-commerce server: passagemail.net — AlmaLinux, cPanel-managed hosting
• Mail server: mail.passagemail.com — Ubuntu 24.04, iRedMail Enterprise Edition, TLS-encrypted
• Database server: MongoDB VPS — Vultr Seattle data center, firewall-restricted access

We implement reasonable security measures including TLS encryption for data in transit, firewall restrictions on database access, and access controls on server infrastructure. No method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

6. Data Retention

@passagemail.com mailbox and email content	Duration of subscription; deleted within 30 days of account closure
Settings backups	Duration of subscription; deleted on request or at account closure

10. International Users

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time.
