SpringApp Technologies ("we," "us," or "our") built DayArc — a weather app for iOS. This Privacy Policy explains what information DayArc accesses, why it accesses it, and how it is handled. We believe in keeping things simple: DayArc does not collect, store, or share your personal information.
DayArc may request access to your device's location in order to provide local weather forecasts and radar for where you are. When you first open the app, you will be asked to choose your preferred level of location access:
You can change your location permission at any time in the iPhone Settings app:
Settings → Privacy & Security → Location Services → DayArc
When weather data is fetched, your approximate GPS coordinates are sent to third-party weather services (see Section 4) solely to retrieve the forecast for your location. No personal information accompanies these requests.
If you have not granted location access, DayArc may use your device's internet connection (IP address) to suggest a starting location. This lookup is performed by third-party services (see Section 4) and is used only to set an initial default. We do not store your IP address or any result from this lookup.
DayArc saves the following information locally on your device only:
You can remove all locally stored data at any time by deleting DayArc from your device.
DayArc uses the following third-party services to deliver weather data, radar imagery, and location detection. When the app communicates with these services, your location coordinates or IP address may be transmitted to them as a normal part of how they work. These services operate under their own privacy policies, which we encourage you to review.
| Service | Purpose | Privacy Policy |
|---|---|---|
| Open-Meteo | Weather forecasts and city search | open-meteo.com/en/terms |
| Rainviewer | Weather radar imagery | rainviewer.com/privacy-policy |
| BigDataCloud | IP-based location detection | bigdatacloud.com/privacy-policy |
| freeipapi.com | IP-based location detection (fallback) | freeipapi.com/privacy-policy |
SpringApp Technologies does not control these services and is not responsible for their privacy practices.
DayArc is distributed through Apple's App Store. Apple may collect standard diagnostic and usage information as part of iOS and the App Store platform. This is governed by Apple's Privacy Policy.
DayArc does not use any third-party analytics tools, advertising networks, or crash reporting services. The only diagnostic information that may be collected is through Apple's standard iOS reporting, which is subject to your device's privacy settings and Apple's own policies.
DayArc is a general-purpose weather application suitable for all ages. We do not knowingly collect personal information from any user. Because no personal data is collected or stored by SpringApp Technologies, the app is appropriate for users of all ages.
All data saved by DayArc (cities and preferences) is stored locally on your device using Apple's secure on-device storage system. SpringApp Technologies does not have access to this data and does not transmit it anywhere.
Because DayArc does not collect or store personal information on our servers, there is no personal data held by SpringApp Technologies to access, correct, or delete.
For any data stored on your device, you are in full control:
We may update this Privacy Policy from time to time. When we do, we will increment the version number and update the effective date shown at the top of this page. Continued use of DayArc after any changes to this policy constitutes your acceptance of the updated terms.
We encourage you to review this page periodically to stay informed.
