Information processed by SunCare
SunCare saves sunscreen applications, manages outdoor activities, and displays UV weather. The current client does not require a SunCare account.
Local data includes application and save times, time zones, activity start and planned end times, reapplication intervals, activity end and undo states, reminder plans, and notification results. The app also stores weather location names, coordinates, time zones and sources, weather caches and update times, activity defaults, and app-generated device identifiers, data generations, and protocol records used for paired sync. These are not advertising identifiers.
Data is stored in the device’s shared app container and is accessible to SunCare components that need it. iPhone and Apple Watch have separate stores; they do not share the same disk.
Weather, location, and external services
City search text is provided to Apple’s map search service. When you choose Current Location, SunCare requests system location access and uses Apple’s place-resolution services to obtain a place name and time zone. Coordinates may be more detailed than a city-level location. Displaying a city name does not mean the coordinates have been reduced in precision.
Weather requests, including widget updates scheduled by the system, provide the saved selected location’s coordinates to Apple WeatherKit. You can select a city manually without current-location access. Denying location access does not prevent weather requests for an already saved location. A temporary location explicitly obtained on Apple Watch is used for watch weather without changing the iPhone selection; the iPhone selection can be synced to the paired watch.
Apple describes WeatherKit location handling in its WeatherKit information. See Apple Maps & Privacy for related service information; the relevant Apple terms and privacy policies apply to each service.
Some weather screens load attribution images from addresses supplied by the service. iPhone and Apple Watch widgets use Apple Weather marks bundled with the app. Opening a weather legal link opens the relevant service page. These connections send the network information needed to complete the request to the provider. Apple’s policies govern its processing and retention. SunCare does not control Apple’s service logs or promise processing exclusively in a particular country or region.
Paired sync and system surfaces
Paired devices with SunCare installed use Apple WatchConnectivity to exchange applications, undo facts, activity states, settings including the selected location, activity-control requests and results, reminder states, and confirmations. Delivery may wait for system transfer and is confirmed only after a response from the other device. Device replacement, conflicts, or different data generations require an explicit recovery choice.
Widgets, complications, Smart Stack, Controls, App Shortcuts, and Siri use system-provided surfaces. They may show location, UV, activity, and reminder information. Actions can include internal activity and data-generation identifiers. You can remove these surfaces in system settings. Unlocking requirements and visibility depend on the surface and system settings.
The current implementation has no SunCare-operated data server, advertising or analytics SDK, HealthKit integration, SunCare sign-in, or app-provided cloud backup. Apple weather, maps, system sync, and system surfaces can still involve off-device processing. Absence of a developer-operated server does not mean that all information stays on the device.
Notifications and permissions
SunCare requests location access when you choose Current Location and notification access for activity reapplication reminders. Reminders are local system notifications with a reapplication prompt and internal identifiers for opening the relevant activity. The current implementation has no developer-operated remote push service.
You can manage location and notification access in system settings. Denying notifications does not delete activities or records. Revoking location access does not automatically remove saved locations or weather caches. The system can delay, silence, or route reminders to another device. Reminder times do not measure remaining sunscreen protection.
Retention, undo, and clearing
Undo hides an application from normal history and retains an undo fact for consistent sync. It does not immediately erase the original database contents.
Clear Local Data cancels this device’s SunCare reminders, clears business records, activities, reminder plans, and related business-sync queues, and pauses business sync for the old data generation. Necessary device or generation barriers, recovery receipts, and pairing-candidate information may remain to reject stale messages and handle retries. The current operation does not clear the Configuration settings store, WeatherCache, WatchTemporaryLocation, or weather-request coordination storage. Saved locations, coordinates, and cached weather can remain in those stores. Choosing restoration from the paired device first clears local business records and activities and then restores data from the explicitly selected source.
Clear Both Devices applies only to the current paired devices and requires confirmation from the other device. An offline or unreachable device is not treated as cleared. This operation also does not clear all location settings or weather caches and cannot guarantee cancellation of reminders on an old, unreachable device.
The current source does not define one automatic deletion period for all local records and auxiliary stores. A stale cache indicator is not proof of cache deletion. Clearing is logical business-data deletion, not a promise of immediate irreversible erasure from database journals, system backups, or storage media. Uninstalling, backups, and device erasure depend on operating-system and device settings. SunCare currently offers no independent cloud-backup guarantee.
Contact, support messages, and changes
For questions about this policy, saved locations, clearing scope, or privacy rights, contact [email protected]. Where applicable law provides such rights, you may request access, correction, or deletion. Identify SunCare and describe your request. Sending an email does not upload local app records, and we cannot read or delete device records remotely using an email address alone. Requests about data held by Apple should use Apple’s privacy channels.
If you send a support or privacy email, the recipient receives your sender address, message, and any files you choose to attach to handle and follow up on the request. Share only necessary information. Do not send passwords, verification codes, payment-card information, precise coordinates, complete histories, or raw databases. Email correspondence is stored separately from local app data; clearing data in the app does not delete emails already sent.
We will update this policy when data handling changes. Subscription purchases, servers, analytics, accounts, or other new processing require updated disclosures and applicable App Store privacy information before the relevant functionality is enabled.
