Boat data and activation
Jolltau reads data from your boat’s interface to display readings, record trips and create reports. Depending on your equipment, this includes boat names and models, interface identifiers and Wi-Fi names, positions and tracks, dates and times, engine hours, fuel and battery readings, and diagnostic recordings. These can be personal data when linked to an identifiable person. Boat data is read-only; Jolltau does not control the boat.
Local storage and permissions
Boat profiles, trips, settings and cached recordings are stored on your iPhone. Interface credentials use the iOS Keychain. The version and date of your privacy acknowledgement are stored locally. Local network access is needed to communicate with the interface. iOS location permission is used to identify the connected Wi-Fi and, where used, obtain phone positions for trip recording. Camera access is optional for scanning activation codes. Photo/File pickers access the item you select. Permissions can be changed in iPhone Settings; refusing them can prevent the associated feature from working. Acknowledging this notice is not blanket consent to data processing.
Purposes and legal bases
Where Nautic Yachting processes personal data necessary to provide the service you request, the legal basis is Article 6(1)(b) GDPR. Optional processing relying on consent requires a separate specific choice under Article 6(1)(a); consent may be withdrawn for the future. No marketing consent is requested by the activation checkbox. There is no statutory obligation to supply boat data; the relevant data is needed to use the corresponding app function.
Reports, maps and recipients
Reports are saved to the Files folder you choose. Choosing iCloud Drive or another cloud provider can cause that provider to upload and process the files under your account settings. Sharing reports or diagnostics sends them to recipients/services you select. The normal local interface connection is not a report upload to Nautic Yachting. Apple supplies map content used in maps and PDF snapshots; map requests can disclose the requested map area and network/device information to Apple. Apple’s separate privacy information applies to its services. App Store/TestFlight distribution and device backup also follow your Apple settings and Apple’s terms.
Storage outside the EEA
Apple or your chosen cloud/sharing provider may process data outside the EEA. Their applicable privacy notices identify locations and safeguards, such as adequacy decisions or standard contractual clauses. Provider-specific roles and safeguards must be checked for the final release; this testing notice does not establish blanket consent to international transfers.
Retention and deletion
Local trips and reports remain until you delete them. Exported files and backups are separate copies: deleting an in-app trip does not delete a cloud export, backup or interface SD recording. Boat profiles, activation credentials and last-recorded readings remain for reuse; Keychain items can survive app removal. Contact us for assistance with complete removal. Data you send for support is retained while necessary to resolve the request and, where applicable, meet legal retention requirements or establish or defend claims.
Your rights
Subject to the applicable GDPR conditions, you may request access, correction, deletion, restriction and portability, and object to processing based on legitimate interests. You may withdraw consent where consent is the basis. Contact the address above. For data held only on your device, we may need your cooperation because we cannot remotely retrieve it. You may complain to a supervisory authority, including the Unabhängiges Landeszentrum für Datenschutz Schleswig-Holstein (datenschutzzentrum.de).
Automated decisions
Activation checks determine access to an interface. Jolltau is not designed to make decisions about people producing legal or similarly significant effects, or to profile people for advertising.
