Your data

Privacy Policy

The apps collect nothing. The website collects very little.

Effective date: October 7, 2026

Veni Navi Vici is a set of free tools for sailors and paddlers:

  • a standalone Apple Watch app that tracks Sail and Paddle sessions
  • an iPhone app that shows the sessions you recorded on the Watch, with a map of each route
  • this website, with the Weather page and the Dashboard in your browser

The apps and the website handle data differently, so each is covered separately below.

The short version

The apps collect nothing. The Watch and iPhone apps have no servers, no accounts, no analytics, no ads, and no third-party code. They contain no networking code at all, so your data physically cannot reach us, and it never leaves your devices except through Apple services you control.

The website collects very little. It keeps anonymous visit counts, and it never sees your location or your sessions. See "This website" below.

Data the Watch app uses on your device

To do its job, the app works with the following data, always with your permission and only while a workout session is active:

  • Location (GPS). Used live to show your current speed and heading on the watch face, and recorded as a route so your session appears with a map in Apple's Fitness app.
  • Health data. The app records your session as a workout in Apple Health, including the GPS route. As part of workout recording, Apple Watch measures your heart rate and active energy (calories); these are stored by Apple Health, not by us.

Data the iPhone app uses on your device

When you finish a session, the Watch app sends a short summary of it (sport, date, time and max speed) directly to the iPhone app on your paired iPhone, so it shows up right away. This goes from your Watch to your iPhone only, never to us.

To show your sessions and their routes, the iPhone app reads the workouts the Watch app recorded, and their GPS routes, from Apple Health. It asks your permission first, for Workouts and Workout Routes only. It never writes to Apple Health, and it never sends anything anywhere: the list and the maps are drawn on your iPhone. If you don't give permission for routes, you still see your sessions, just without maps.

Where your data lives

Everything the Watch app records is stored in Apple Health on your own devices, and the iPhone app reads it from there. Apple Health data may sync between your devices via iCloud if you have enabled that — this is governed entirely by your Apple account settings and Apple's privacy policy, not by us. We have no access to it, ever.

What the apps never do

  • No collection, transmission, sale, or sharing of any personal data
  • No analytics or crash reporting
  • No advertising or tracking of any kind
  • No accounts, sign-ins, or identifiers
  • No third-party SDKs

This website

Everything above is about the Veni Navi Vici apps, which truly collect nothing. This website (the one you're reading this on) is different: we use Ahoy, a minimal, self-hosted analytics tool, to see anonymous counts of page visits and a couple of button clicks, like the App Store link, the web app's START button, and when the Weather page fetches a forecast. We don't collect names, emails, or any other personal identifiers; IP addresses are masked before they're ever stored; there are no accounts, no ads, and no cookies used to track you across other sites; and nothing is ever sold or shared with third parties.

The Weather page asks your browser for your location and sends the coordinates directly from your browser to Open-Meteo's free weather API to fetch the forecast. Our server never sees your coordinates, and we store nothing. To avoid asking again too often, your browser keeps the last forecast and its rounded position (about 100 m) in local storage on your device for 30 minutes; it's never sent anywhere.

The Dashboard in your browser reads your location only on your device. It keeps your last 5 sessions, including their GPS routes, in your browser's local storage so you can see them next time, and never sends them anywhere. If you tap Share, the image is made on your phone and contains your speeds and the shape of your route, but no map or coordinates. If you export a GPX file, it does contain your route's coordinates, and it only goes wherever you choose to send it.

Your control

  • You can revoke Health and Location permissions at any time in the Settings and Health apps; the Watch app will simply record less, and the iPhone app will show less.
  • You can view and delete every workout the app has recorded in the Apple Health and Fitness apps.
  • Deleting the apps removes them entirely; workouts already saved to Apple Health remain yours to keep or delete there.

Changes

If a future version of the app ever changes any of the above, this policy will be updated before that version is released.
