Sjökortis Privacy Policy

1. Who is responsible for your personal data?

The controller for the processing described in this policy is:

2. Summary

Sjökortis works entirely without an account and without the internet. Your navigation data (tracks, places, routes, zones, races, boat profiles and settings) is stored only on your device. The app sends no data to us or to any server we operate, and it contains no advertising, no tracking and no analytics or telemetry service.

Data only leaves your device when you choose: when you export or share a file, when you share GPS position with your own devices on the local network, or when you email our support.

3. What data is processed, and where?

3.1 Location and track log — locally on the device

• The app uses your precise location (the “while using” permission — the app never asks for “always”) to show the boat on the chart, hold a course, run routes and races and operate the anchor watch, including with the screen off when you have activated the anchor watch, race timing or GPS sharing yourself.
• The track log (“Log track”) stores your route locally on the device in the app’s database. It is on by default, can be turned off in the settings, is automatically pruned after 180 days and can be deleted entirely at any time with “Clear tracks”.
• The anchor watch alarm is a local notification on your device (it contains the drift distance, never coordinates). The app uses no push notifications and has no notification server.

We have no access to your location or your track log.

3.2 Features on the local network (never leave it for the internet)

• GPS sharing between your devices (“Share my GPS” / “Receive GPS from iPhone”) sends position packets only over the local network (Wi-Fi/hotspot on board). No data leaves the local network.
• NMEA/AIS gateway: the app can receive position and AIS data (other vessels’ MMSI, name, position, etc.) from your own receiver on board. The data is shown in real time, held only in memory and never uploaded anywhere.

3.3 Imported files

Charts and GPX files you import stay on your device and are not sent anywhere.

3.4 Diagnostics (local only, manual export)

The app stores Apple’s MetricKit diagnostics (crashes, performance — never location) locally on the device, going back a maximum of about two months. They are never sent automatically anywhere; they only leave the device if you choose “Export diagnostics” yourself and share the file, for example with our support. The app contains no third-party crash or analytics service.

If you have chosen in iOS to share analytics with app developers, Apple may pass anonymised crash and usage statistics on to us. This is governed by your iOS settings and Apple’s terms.

3.5 Export, sharing and the clipboard

GPX exports and race result images are sent via the iOS share sheet or the clipboard only at your initiative — the recipient is the app or person you choose. Note that iOS Universal Clipboard can make the clipboard available on your other Apple devices; this is a system feature outside the app’s control.

3.6 Local storage and backups

Your local data (track log, places, routes, zones, races, boat profiles, settings and last map position) is included in the device’s normal iCloud/computer backup according to your iOS settings. The app uses no cloud sync of its own. If you delete the app, the data on the device is deleted.

3.7 Support

If you email us, we process your email address, your message and any files you attach (for example a diagnostics file) in order to answer your request.

4. Legal basis

The processing in sections 3.1–3.6 takes place on your device and under your control; we receive none of this data. We process support requests (section 3.7) on the basis of our legitimate interest in being able to answer your questions (Art. 6(1)(f) GDPR).

5. Recipients

We never sell your data and do not share it with anyone. Data only reaches the recipients you choose yourself when you export or share something.

6. How long is data kept?

7. Your rights

You have the right to request access (a copy of your personal data), rectification, erasure, restriction and data portability, and to object to processing. Because the app’s data exists only on your device, in practice this applies to support requests; you control the local data yourself:

• Turn off the track log, clear tracks and delete individual places, routes, zones, races and boat profiles.
• Export routes and tracks as GPX (data portability).
• Delete the app to remove all app data from the device.

For other requests, contact support@sjokortis.se. We respond to requests within one month.

You always have the right to lodge a complaint with the Swedish Authority for Privacy Protection (IMY), Box 8114, 104 20 Stockholm, www.imy.se.

8. Changes to this policy

If the app gains features that process data outside the device, we will update this policy before they are released, inform you in the app and update the date at the top. The policy must always reflect the app’s actual behaviour and the App Store privacy declaration.
