Privacy Policy

Last updated 9 September 2026

SeaWindow is a marine-weather app for small-boat anglers, published by Mitux LLC(California). This policy explains what the app collects, why, who processes it, and the choices you have. We collect as little as the app can work with.

The short version. You can use SeaWindow without an account. The app uses your location only while you have it open, to show conditions near you. There areno ads, no advertising identifiers, and no third-party analytics or tracking, and we never sell or rent your information.

Using SeaWindow without an account

An account is optional. Without one, the app works normally: your device holds your saved spots and settings, and our server answers weather requests for the area you are looking at. An account exists only to link several of your own devices so your saved spots appear on all of them.

What we collect and why

Location. With your permission, the app uses your device locationonly while the app is in use — to show conditions near you and to center the spot picker. It is not used in the background and the app does not track your movements. To answer “what are conditions here?”, the coordinates you are viewing are sent to our server, which fetches the forecast for that area. In our server logs, coordinates are truncated to roughly 0.1° (about 11 km) so precise positions are not stored.

Spots you save. The name and coordinates of each spot you add. Spots are stored on your device; if you sign in, they are also stored on our server so they sync to your other devices.

Alerts you set. The thresholds you choose for a spot (such as maximum wind, gust, wave height and minimum wave period) and whether to be notified on official marine warnings. We store these to evaluate conditions and notify you.

A device record. An app-generated device identifier (a random ID created by the app — not your phone’s advertising identifier), your platform (iOS or Android), language, unit preference, and your selected boat profile. If you turn on alerts, we also store a push-notification token for your device. This keeps your settings and lets us deliver alerts.

Account details (only if you sign in). If you sign in by email, we store your email address. If you use Sign in with Apple, we store the stable identifier Apple gives us and the email or private-relay address Apple returns — Apple may hide your real email. Sign-in codes and session tokens are stored only as hashes; the usable token is shown to your device once and never stored in the clear.

Who processes your data

  • Our own server. Mitux LLC’s backend receives your area requests, spots, alert rules, device record and account details. (It runs on our own infrastructure and is moving to a dedicated server before wider launch.)
  • Weather & marine data sources. To answer a request, our server queriesOpen-Meteo and the U.S. government services NOAA, NWS, NDBC and CO-OPS for forecasts, buoy observations, tides and official warnings. They receive an approximate location or the nearest station — not your identity or account.
  • Email delivery — Resend. Only when you sign in by email, to send your one-time code. Resend receives the recipient address and the code.
  • Push delivery. If you enable alerts, notifications are delivered through Apple Push Notification service (iOS) or Firebase Cloud Messaging (Android) via Expo’s push service, using your device’s push token.
  • App stores. Apple and Google handle app downloads and any future purchases under their own privacy policies.

What we do not do

  • No advertising SDKs and no advertising identifiers.
  • No third-party analytics, tracking, or profiling SDKs.
  • No background location tracking.
  • We do not sell or rent your personal information.

How we protect it

Traffic between the app and our server is encrypted in transit (HTTPS). Sign-in codes and session tokens are stored only as SHA-256 hashes. Coordinates are truncated before they reach our logs.

How long we keep it

Your account, spots and alert rules are kept while your account or device is active, until you delete them. Sign-in codes expire within minutes. Cached weather data on our server is not personal to you.

Your choices and rights

You can use the app without an account; sign out at any time (your spots stay on the device); and delete your account and everything synced to it — use the delete option in the app, or email us and we will delete it for you. You may also ask us what we hold about you and to correct it. Write to contact@mituxlabs.com.

California & U.S. privacy

California residents have the right to know what personal information we hold, to have it deleted or corrected, and not to have it sold. We do not sell personal information. To exercise any of these, contact contact@mituxlabs.com; we will not discriminate against you for doing so.

International users

Our servers are in the United States. If you use the app from elsewhere, your information is processed in the United States.

Children

SeaWindow is not directed to children under 13, and we do not knowingly collect their personal information.

Changes

If this policy changes, the “last updated” date above changes with it.

隐私

隐私政策

最后更新 2026年9月9日

SeaWindow（出海窗口）是一款面向开小船出海钓鱼者的海洋天气 App，由 Mitux LLC（美国加州） 发布。本政策说明 App 收集什么、为什么收集、由谁处理，以及你有哪些选择。我们只收集 App 运行所需的 最少信息。

一句话版本。不登录也能用 SeaWindow。只有在你打开 App 时才用你的位置来显示附近海况。没有广告、没有广告标识符、没有任何第三方分析或追踪，我们也绝不出售或出租你的信息。

不登录使用

账号是可选的。不登录时 App 照常工作：你的点位和设置存在本机，服务器只为你正在查看的区域返回天气。 账号只干一件事——把你自己的多台设备串起来，让保存的点位在每台设备上都能看到。

我们收集什么、为什么

位置。在你授权后，App 仅在使用期间读取设备位置，用来显示你附近的 海况、并把选点地图居中到你所在处。不会在后台使用，App 也不会追踪你的行动轨迹。为回答「这里现在什么 海况？」，你正在查看的坐标会发到我们服务器，由服务器去取该区域的预报。在服务器日志里，坐标会被截断 到约 0.1°（约 11 公里），因此不会记录精确位置。

你保存的点位。你添加的每个点位的名称和坐标。点位存在本机；若你登录，也会存到我们 服务器，以便在你的其他设备间同步。

你设置的告警。你为某个点位选择的阈值（例如最大风速、阵风、浪高，以及最小浪周期）， 以及是否在官方海洋警报时提醒你。我们保存这些用于判断海况并通知你。

一份设备记录。由 App 生成的设备标识（App 随机生成的 ID，不是你手机的 广告标识符）、你的平台（iOS 或 Android）、语言、单位偏好，以及你选择的船型。如果你开启告警，我们还会 保存你设备的推送令牌。这些用于保留你的设置并发送告警。

账号信息（仅在你登录时）。若用邮箱登录，我们保存你的邮箱地址；若用「通过 Apple 登录」，我们保存 Apple 给出的稳定标识，以及 Apple 返回的邮箱或私密转发地址——Apple 可能隐藏你的 真实邮箱。登录验证码和会话令牌只以哈希形式存储；可用的令牌只回给你的设备一次，绝不明文保存。

谁会处理你的数据

  • 我们自己的服务器。Mitux LLC 的后端接收你的区域请求、点位、告警规则、设备记录 和账号信息。（运行在我们自有的基础设施上，正式扩大上线前会迁到独立服务器。）
  • 天气与海洋数据源。为回应请求，我们服务器会向 Open-Meteo 以及美国 政府机构 NOAA、NWS、NDBC、CO-OPS 查询预报、浮标实测、潮汐和官方警报。它们拿到的是 大致位置或最近的测站——不是你的身份或账号。
  • 邮件发送——Resend。仅在你用邮箱登录时，用于发送一次性验证码。Resend 会拿到收件 邮箱和验证码。
  • 推送发送。若你开启告警，通知会经 Expo 推送服务，通过 Apple 推送服务（iOS）或 Firebase 云消息（Android）送达，使用你设备上的推送令牌。
  • 应用商店。Apple 与 Google 依其各自的隐私政策处理 App 下载及未来可能的付费。

我们不做的事

  • 不含广告 SDK，不使用广告标识符。
  • 不含任何第三方分析、追踪或画像 SDK。
  • 不做后台位置追踪。
  • 不出售、不出租你的个人信息。

我们如何保护

App 与服务器之间的通信在传输中加密（HTTPS）。登录验证码和会话令牌仅以 SHA-256 哈希存储。坐标在进入 日志前已被截断。

保留多久

你的账号、点位和告警规则在你的账号或设备活跃期间保留，直到你删除。登录验证码在几分钟内失效。服务器上 缓存的天气数据不涉及你的个人身份。

你的选择与权利

你可以不登录使用；随时退出登录（点位仍留在本机）；并删除你的账号及其同步的一切——用 App 内的删除功能，或给我们发邮件，我们会为你删除。你也可以询问我们持有你的哪些信息并要求更正。请写信到contact@mituxlabs.com。

加州及美国隐私

加州居民有权知悉我们持有的个人信息、要求删除或更正，并要求不被出售。我们不出售个人信息。要行使上述 权利，请联系 contact@mituxlabs.com；我们不会因此对你区别对待。

境外用户

我们的服务器位于美国。若你在其他地区使用本 App，你的信息将在美国境内处理。

儿童

SeaWindow 不面向 13 岁以下儿童，我们也不会有意收集其个人信息。

变更

本政策如有变更，上方的「最后更新」日期会随之更新。
