Privacy Policy | NimoSail

IN SHORT

We only collect what’s needed to log and share your sails.
Your location is used only while you record a sail.
Your sails are private unless you choose Friends.
No ads, no tracking, and we never sell your data.
You can download or delete your data at any time.

Who we are

NimoSail is a sailing logbook app made by Pete Jackson, an independent developer based in Israel. In this policy, “we” means Pete Jackson, and “you” means anyone using the app.

If you have a question about your data, email support@nimosail.app.

What we collect

We only collect what the app needs to work. Most of it you type in or choose yourself.

Your account

Your email address and password. Passwords are stored encrypted by our database provider and we can never see them.

Your profile

Name, username, role, licence, phone, email, social link, bio, profile photo and cover photo. Everyone chooses a username when they first sign in; everything else is optional.

Your sails

GPS track, start and end times, distance and speeds, place, weather, sea state, notes, photos, and the boat and crew you choose.

Boats, crew and plans

Boats in your Fleet, crew records you add, and Noticeboard plans.

Friends

Friend requests you send, receive and accept, sails you send to each other, and which of your crew records you’ve linked to a friend’s account.

Messages to us

What you write in Contact us, any screenshot you attach, and (if you leave the box ticked) your app version and device type.

Error reports

If something goes wrong in the app, a short technical report is sent automatically: the error message, the app version, your device type and which screen was open. It never includes your sails, photos or location.

We don’t use advertising, analytics or tracking tools, and we don’t collect your contacts.

Your location

The app uses your location only while you are recording a sail, to draw your track and measure distance and speed.

The app only asks for location “while using the app”. While a sail is being recorded, a notification stays on your phone, and that is what lets recording carry on with the screen off. When no sail is being recorded, the app does not collect your location.

When you cast off, and when your weather report is made, the app sends the position of your sail (latitude and longitude only, nothing about you) to Open-Meteo to get the weather.

To fill in the Place of a recorded sail, the app sends its starting position to OpenStreetMap, which returns a place name. For a sail you log by hand, it sends the Place name you typed to OpenStreetMap to find its position, so the weather for that sail can be looked up. Nothing about you is sent with these.

How we use your data

To run the app: save your sails, keep your devices in sync and back up your photos.
To show your shared sails and plans to the friends you choose.
To reply to your messages and fix problems you report.
To keep the app secure and prevent misuse.

We never sell your data, never use it for advertising, and never share it with anyone except the services listed below, which help run the app.

Who can see what

Only you

Everything you log, unless you choose to share it. Sails and plans are private by default.

Your friends

Sails and Noticeboard plans you mark Friends, plus your profile details, and only once you’ve both accepted.

Everyone using the app

Your username, display name and profile photo, so other sailors can find you and send friend requests. Your email address is never shown, but someone who already knows it can use it to find you.

Sails you send to a friend

When you send a sail to a friend’s app, they get their own copy, including its photos and the names of the skipper and crew on that sail. Once they add it to their log, that copy is theirs.

Your crew records

Only you. Crew records are your private notes. Only the names of the crew on a sail go with it when you choose to send that sail to a friend.

Services we use

These companies process data for us to make the app work. Each has its own privacy policy.

Supabase stores your account, sails, photos and messages on servers in Frankfurt, Germany (European Union).
Google (Gmail) sends the app’s sign-up and password-reset emails, so it handles your email address for those.
GitHub Pages hosts the web version of the app and this page.
Open-Meteo provides weather for your sail’s position.
Mapbox provides the maps, and OpenSeaMap adds sea marks on the Nautical map. Like any website, they see your IP address and the map area being shown.
OpenStreetMap turns positions into place names and place names into positions (see “Your location”).
Google Fonts and cdnjs deliver the app’s fonts and code libraries and see your IP address.

Crew and other people

When you add crew or mention people in notes and photos, you’re sharing information about them. Please only add people who are happy to be included. Crew records stay private to you.

How long we keep it

We keep your data for as long as you have an account. When you delete a sail, photo or plan, it’s removed from our servers. When you delete your account, everything linked to it is removed, including messages you’ve sent us. Messages you send us are kept for up to 12 months, and error reports for 90 days. Sails you sent to a friend that they added to their own log are their copies, so they stay in their account.

Copies of your data saved on your phone stay there until you delete them or use Reset App Data.

Your choices and rights

See and correct your data at any time in the app.
Download a copy with Settings → Backup to File.
Delete anything you’ve logged at any time, or delete your whole account in Settings → Account → Delete account. This removes your account and all its data from our servers straight away, and you can choose whether to keep a copy on your phone. If you can’t use the app, email us and we’ll delete it for you within 30 days. Full steps: Delete your account.
Stop location at any time in your phone’s settings. Recording won’t work without it.

Depending on where you live, you may have further rights under data-protection law. To use any of them, email support@nimosail.app.

Keeping it safe

All data travels over encrypted connections. Our database only lets each person read their own data, plus what friends have chosen to share with them. No system is perfectly secure, so please use a strong password.

Children

NimoSail is not intended for children under 16. We don’t knowingly collect data from them.

Changes to this policy

If we make important changes, we’ll tell you in the app before they take effect. The date at the top shows the latest version.
