1. Overview
This Privacy Policy applies to the Solstice iPhone application (the “App”) and the Solstice website (together, the “Services”). Solstice helps you understand solar position, daylight events, golden and blue hour, shadow direction, and related planning information for a place and time.
No Solstice account is required. Core solar calculations are performed on-device after a coordinate and timezone are known. Solstice does not sell personal information and does not use your information for third-party advertising.
2. Information the App may use
Location
If you choose “Use My Location” or another feature that needs your current location, the App may request iOS “When In Use” location permission. Location is used to calculate solar information, position the map, and support place-based features. Solstice does not request background location access.
Camera and device orientation
If you open the augmented-reality experience, the App may request camera access and use motion, orientation, or compass information to align solar visualizations. Camera imagery is used for the live AR experience and is not uploaded by Solstice for storage or advertising.
Notifications
If you intentionally create a solar alert, the App may request notification permission and schedule local notifications on your device. Notification permission is optional.
Saved places and preferences
Places, planning choices, app preferences, and related app state may be stored locally on your device so the App can provide its features. You control these items through the App and your device.
Subscription and entitlement information
If you use paid features, Solstice receives or derives information needed to determine whether your subscription is active, such as product identifiers, purchase status, entitlement status, and transaction-related identifiers. Payments are processed by Apple; Solstice does not receive your full payment-card details.
Technical information
The App and its service providers may process limited technical information necessary to operate paywalls and subscriptions, such as app version, operating-system version, device or app identifiers, locale, region, diagnostic information, paywall presentation events, and subscription context.
3. Third-party services
Solstice uses platform and service providers to deliver specific functionality. Their processing is also governed by their own terms and privacy practices.
Apple
Apple provides App Store purchase processing and may provide MapKit, map tiles, search, Look Around, location permission controls, notifications, and other iOS platform services. Information sent to Apple through those services is handled under Apple’s applicable privacy terms.
Superwall
Solstice uses Superwall to configure, select, present, and measure paywalls. Superwall may process a pseudonymous app or device identifier, app and device information, locale or region, paywall presentation and interaction events, experiment or campaign metadata, and subscription context needed to decide which paywall to show and to evaluate paywall performance. Solstice does not use Superwall to serve third-party advertising.
RevenueCat
Solstice uses RevenueCat to manage subscription status and paid-feature entitlements. RevenueCat may process a pseudonymous app user identifier, App Store product and transaction information, subscription and entitlement status, app and device information, and related diagnostics needed to validate purchases, synchronize entitlement state, and support purchase restoration.
Cloudflare
This website is hosted using Cloudflare infrastructure. Cloudflare may process network information such as IP address, request metadata, and security-related signals as needed to deliver and protect the website. The website itself is currently designed without advertising trackers or marketing cookies.
4. How information is used
Information described above is used only as reasonably necessary to:
- provide solar calculations, maps, AR visualization, saved-place planning, alerts, widgets, and related App features;
- present and improve subscription paywalls and determine subscription entitlements;
- process or restore purchases through Apple and RevenueCat;
- maintain reliability, diagnose problems, prevent abuse, and provide support;
- comply with legal obligations and enforce applicable terms.
Solstice does not sell personal information, does not rent personal information, and does not use personal information for cross-context behavioral advertising.
5. Data retention
Locally stored App data remains on your device until you delete it, reset the relevant feature, or remove the App, subject to iOS backup and device behavior. Service providers may retain subscription, transaction, paywall, diagnostic, and security records for the period reasonably necessary to provide their services, maintain financial or legal records, prevent fraud, and comply with law.
Support emails and related correspondence may be retained as needed to resolve your request and maintain an appropriate record of support activity.
6. Your choices and rights
You can control location, camera, and notification permissions at any time in iOS Settings. You can delete saved App data through the App where controls are provided or by removing the App from your device. You can manage or cancel App Store subscriptions through your Apple account’s subscription settings.
Depending on where you live, privacy law may give you rights to request access, correction, deletion, restriction, objection, portability, or other action regarding personal information associated with you. Because Solstice does not require an account and some service data is pseudonymous, we may need information from you to identify records that can reasonably be linked to your request.
To make a privacy request, email augustin.dev@tutamail.com. We may retain information where required by law or where an applicable exception permits retention.
7. Children’s privacy
Solstice is not directed to children under 13, and we do not knowingly collect personal information from children under 13 through an account system. If you believe a child has provided personal information to us in a way covered by applicable law, contact us so the situation can be reviewed.
8. Changes to this policy
We may update this Privacy Policy as the Services, integrations, or legal requirements change. The effective date at the top of this page will be updated when a revised policy is published. Material changes may also be communicated in the App when appropriate.
