1. Overview
This privacy policy applies to the Tantastic Sunglow iPhone app and this website, provided by Lemar Systems Ltd (“we”, “us” or “Tantastic”).
Tantastic does not require you to create an account with us. The app’s personal profile, tanning history, achievements and glow photos are designed to be stored on your device. The current App Store privacy label states that the developer does not collect data.
Some app features rely on Apple platform services and RevenueCat, as described below. Those providers process information under their own privacy policies.
2. Information stored on your device
Tantastic stores the information needed to personalise and run the app locally on your iPhone. This may include:
- Your skin type, tanning goal, sun response and onboarding choices.
- Completed session history, streaks, glow levels, achievements and coarse place labels associated with completed sessions.
- App preferences, reminder settings and subscription entitlement state.
- Optional glow photos and the dates they were saved.
This local information is removed when you delete it through the app, where that option is available, or when you delete the app from your device. iCloud or device backups may retain app data according to your Apple backup settings.
3. Location and weather
If you choose “Use my location”, Tantastic asks iOS for location access while you use the app. Your location is used to request local conditions such as hourly UV, temperature, sunrise and sunset from Apple Weather, and to show a readable place name.
Tantastic does not operate a server that stores your precise location. Completed sessions may keep a coarse place snapshot—such as city, region and country—on your device so your Journey can show where a session took place.
You can decline location access or turn it off at any time in Settings → Privacy & Security → Location Services → Tantastic. Features that depend on live local weather will then be limited.
Weather and geocoding requests are provided by Apple and are subject to Apple’s Privacy Policy.
4. Camera and glow photos
Glow Progress is optional. If you take or choose a photo, Tantastic saves a resized copy inside the app’s private storage on your device. Tantastic does not upload those photos to a Lemar Systems server.
The app may analyse basic image characteristics on your device to help organise a glow baseline. Your photos are included in a share image only when you choose to create and share one using the iOS share sheet.
You can remove individual glow photos from the app. You can also change camera and photo-library permissions in iOS Settings.
5. Subscriptions and purchases
Purchases are completed through Apple’s App Store. Apple processes your payment details; Tantastic does not receive your full payment card information.
Tantastic uses RevenueCat to offer purchases, restore subscriptions and determine whether Pro features are active. RevenueCat may process an anonymous app user identifier, product and transaction information, subscription status, and Apple Ads attribution information where available. Read the RevenueCat Privacy Policy for details.
Apple’s own terms and privacy policy apply to App Store payments and Apple Ads attribution.
6. Notifications
If you enable reminders, Tantastic can schedule local notifications on your device for planned tanning windows or session timing. You can change notification access at any time in iOS Settings.
7. This website
This website is a static product site. It does not use account sign-in, advertising pixels or analytics cookies. If that changes, this policy will be updated before those tools are introduced.
If you email support, we receive the information you choose to include in your message and use it to reply to you. We retain support correspondence only as long as reasonably needed to resolve the request and meet legal obligations.
8. Children
Tantastic is not directed at children. We do not knowingly ask children to provide personal information to us. If you believe a child has sent personal information to our support team, contact us so we can review and delete it where appropriate.
9. Your choices and rights
You can control Tantastic’s access to location, photos, camera and notifications through iOS Settings. You can remove local app data by using the app’s available deletion controls or deleting the app.
If you contact us, privacy laws may give you rights over personal information held in that correspondence, including rights to access, correct or delete it. These rights vary by location and may have legal exceptions.
To make a privacy request, email support@lemar-systems.com. We may need enough information to confirm the request relates to you.
10. Changes to this policy
We may update this policy when Tantastic’s features, service providers or legal obligations change. The date at the top of this page shows the latest revision. Material changes will be communicated in the app or on this page where appropriate.
