Privacy policy

Version 2026-11-08 · Effective November 8, 2026

This policy explains how Novadri LLC ("Novadri", "we", "us"), a Washington limited liability company, collects, uses and shares information through the Marine Maps app for iPhone, iPad and Apple Watch, the marinemaps.app website, and the online services they use (together, "Marine Maps"). Novadri is the controller of the personal data described here.

In short: you can use Marine Maps for the first 14 days without an account; after that, a free account is needed. Your location stays on your device, except in the waypoints, routes and tracks you save to your account and positions you choose to share. We don't track you across other apps or websites, and we don't sell or rent your personal data. The app counts which features are used, without linking that to your account, and you can turn it off in Settings → Privacy. Product news is sent only if you opt in.

1. Before you create an account

For the first 14 days you can use Marine Maps without an account. Until you sign in, your waypoints, routes, tracks, boats, settings and alarms are stored only on your device (and in your own iCloud or device backups, if you use them). We don't receive them.

To show charts, tides and weather, the app requests public data from the services below. These requests do not include your name, account or any identifier from us. Like any internet request, they reveal your device's IP address to the server, and some include a map position.

Service	What the app asks for	What the request includes
Marine Maps servers (Amazon Web Services)	Chart, tide station, current station and marina indexes	Nothing beyond the request itself
NOAA (charts.noaa.gov, tidesandcurrents.noaa.gov, nowcoast.noaa.gov, ndbc.noaa.gov)	Chart downloads, tide and current data, weather overlays, buoy observations	Chart or station names, or the map area for overlays
National Weather Service (api.weather.gov)	Marine forecasts and alerts	The position you request a forecast for (your boat or the map centre)
Apple (MapKit)	The base map	The map area on screen, handled under Apple's privacy policy

Location. With your permission, the app uses your device's location on the device to show your boat, record tracks, sound alarms and plan routes. While a track, anchor alarm or route is active, location may be used in the background (iOS shows a location indicator). Without an account, your location is not sent to us. You can change location permission at any time in iOS Settings.

2. If you create an account

Accounts are free and are needed after the first 14 days. You can sign in with Apple or with a one-time email code. When you do, we collect and store:

Identifiers and contact details: your email address (with Sign in with Apple and "Hide My Email", an Apple relay address), a user ID, and, for Sign in with Apple, a token that allows us to revoke Apple sign-in when you delete your account. If you share your name through Sign in with Apple, we use it only to suggest your display name.
Profile: the display name and @handle you choose, and your settings such as whether new followers need approval.
Your content: boats (name, type, dimensions and details you enter), waypoints, routes and tracks, so they sync across your devices. Routes, waypoints and tracks contain positions.
Social activity: who you follow and who follows you, follow requests, blocks, the routes and positions you share and with whom, and reports you make or that are made about you.
Shared positions: only if you turn on location sharing. Your position is uploaded while sharing is on and is visible only to the people you choose. It is never public, and it is deleted when the sharing period ends.
Records of your choices: the version and date of the Terms you accepted, and whether and when you opted in to product news.

Other users see only your display name, @handle, and what you choose to share with them.

3. Notifications and emails

Alerts you set up (anchor and arrival alarms, chart updates) are created on your device. You can turn notifications off at any time in iOS Settings.
Service emails (sign-in codes, security, account and important legal notices) are sent to account holders as part of the service.
Product news (opt-in only). If you turn on "Product news and tips" in Settings → Notifications, we may send occasional push notifications and, if you have an account, emails about new features, updates, tips and offers for Marine Maps. To send push notifications, we store a push token for your device. You can opt out at any time in the app, in iOS Settings, or through the unsubscribe link in any email. We don't use push notifications to send sensitive personal information.

4. Support, website and diagnostics

Support: if you email us, we keep your message and email address to answer you and to improve Marine Maps.
Website: marinemaps.app uses no cookies and no analytics. Our hosting provider may log technical request data (such as IP address, time, page and browser type) for security and troubleshooting.
Crash reports: if you choose to share analytics with app developers in iOS settings, Apple provides us with anonymised crash reports and usage statistics.

Analytics and diagnostics

To learn which features are used and what goes wrong, the app sends usage events, not linked to your account, to PostHog (PostHog Inc., United States), which processes them for us as a service provider.

What is counted: actions such as opening a screen, downloading charts, saving a route or opening a tide station; how long the app is in use; app version, iOS version, device model, language, time zone, the region you chose in iOS, a broad sea area (for example "Puget Sound") worked out from the charts you installed, and coarse numbers such as "5–20 nautical miles"; crash and performance reports from iOS (MetricKit); and short error codes such as "http_503".
What is never sent: your position or any coordinates, names of places, waypoints, routes or boats, search text, messages, your email, name or account ID.
Identifier: a random ID created on your device and kept in its Keychain. It is not linked to your account, and it is not used to track you in other apps or websites. Because events from one device share this ID, they are pseudonymous rather than fully anonymous.
IP addresses are not stored: PostHog discards them and does not look up a location from them.
Turning it off: Settings → Privacy → "Share usage data". In the EU, EEA, UK and Switzerland it stays off until you agree. When you turn it off, events not yet sent are deleted.

Feedback form

If you send feedback from the app, we store the message, the type you picked, and, if you leave "Include app info" on, the app version, iOS version, device model, language, units, number of charts, whether you are signed in, your active boat type and the last few error codes. "Report a chart problem" also stores the chart name and object type, and the map position only if you turn on "Include map position". If you send it under your @handle, it is linked to your account so we can reply to your account email; anonymous feedback is not linked to your account, and we can reply only if you give an email. Feedback is stored in our Supabase database and is read only by us.

5. What we don't do

No tracking across other companies' apps or websites.
No third-party analytics, advertising or tracking SDKs in the app. Usage analytics (above) are sent by our own code and are not linked to your account.
No selling or renting of personal data.
No use of your content or location to train AI models.

If we add advertising to Marine Maps, we will update this policy before it starts, and we will ask for your permission first wherever the law or Apple's rules require it.

6. How we use information, and our legal bases

To provide Marine Maps and the features you ask for: sign-in, sync, sharing, people and alerts (performance of our contract with you).
To keep Marine Maps safe and working, prevent abuse and fraud, review reports, enforce our Terms and fix problems (our legitimate interests in a safe, reliable service).
To send product news, only with your consent, which you can withdraw at any time.
To comply with the law and respond to lawful requests (legal obligation).

Precise location and other sensitive information are used only to provide the features you use, and never to infer characteristics about you.

7. Who we share information with

Service providers who process data for us under contract and only on our instructions: Supabase (database, sign-in, server functions, sign-in and service emails, feedback), Amazon Web Services (website and data hosting), PostHog (usage analytics) and Apple (Sign in with Apple, push notifications, App Store).
Other users, only the profile and content you choose to share with them.
For legal reasons: when we believe in good faith that the law, a court order or a valid government request requires it, or that it is necessary to protect someone's safety, to investigate abuse, or to protect the rights and property of Novadri or others.
Business transfers: if Novadri is involved in a merger, acquisition, financing or sale of assets, information may be transferred as part of that transaction, subject to this policy.

8. How long we keep it

Account data and content: until you delete it or your account.
Shared positions: deleted when the sharing period ends.
Reports and moderation records: up to two years after the report is resolved, and longer if needed for a legal claim or to prevent repeat abuse.
Push tokens: until you opt out of product news, delete the app, or delete your account.
Server and website logs: up to 90 days.
Usage events: up to 2 years.
Feedback: until it has been dealt with, and at most 2 years.
Backups: overwritten within 30 days.

9. Your choices and rights

Delete your account in the app: Settings → Account → Delete account. This deletes your profile, boats, routes, waypoints, tracks, follows and shares from our servers, and revokes Sign in with Apple. Data stored on your devices remains until you delete the app.
Export your routes and tracks as GPX files from My Data.
Correct your profile at any time in the app.
Location and notifications: turn them off at any time in iOS Settings.
Product news: turn it off at any time in Settings → Notifications.
Usage analytics: turn it off at any time in Settings → Privacy.

Depending on where you live, you may have the right to access, correct, delete or receive a copy of your personal data, to object to or restrict its use, to withdraw consent, and to appeal our decision on a request. To use these rights, email info@novadri.net from the address linked to your account, or say how we can verify that you are the account holder. We respond within the time the law requires (usually 30–45 days). You may use an authorised agent where the law allows, and we will not discriminate against you for exercising your rights.

US state privacy laws (including California). In the past 12 months we have collected the following categories of personal information, for the purposes and from the sources described above: identifiers; customer records (email); geolocation data; user content; and internet or other electronic network activity (server logs and app usage events). Precise geolocation is "sensitive personal information" and is used only to provide the features you request. We do not sell or share personal information, as those terms are defined in California law, and we have not done so in the past 12 months.

EU, UK and Switzerland. You can also complain to your local data protection authority. Our service providers are located in the United States and other countries; where data is transferred out of your country, they use safeguards such as the European Commission's Standard Contractual Clauses.

Do Not Track. We don't track you across websites, so we don't respond differently to browser Do Not Track signals.

10. Children

Marine Maps accounts are for people aged 13 or older. We don't knowingly collect personal information from children under 13. If you believe a child under 13 has given us personal information, contact us and we will delete it.

11. Security

Data travels over encrypted connections (HTTPS). On our servers, access rules ensure that only the owner of a record, and the people they shared it with, can read it. Sign-in sessions on your device are kept in the iOS Keychain. No system is perfectly secure, so we can't guarantee absolute security. If a breach affects your personal information, we will notify you and the authorities as the law requires.

12. Changes to this policy

If we change this policy, we will update the version and date above. If a change is material, we will tell you in the app before it takes effect, and we will ask for your consent where the law requires it.
