Privacy Policy

This Privacy Policy explains how upCal handles user and device data.

By using the app, you acknowledge that you have read and agree to this policy. If you do not agree, please discontinue use of the app.

1. Location Privacy

This app itself does not collect, store, or track your location data (latitude and longitude).

However, when certain optional features are used — such as satellite imagery, street maps, or automatic location name detection — your device's GPS coordinates may be processed by third-party services. These services require an internet connection.

1.1 Satellite & Aerial Imagery

Satellite and aerial imagery are provided by ArcGIS Online:

server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer

Use of these services is subject to Esri's terms and policies.

1.2 Street Map Tiles

Street map tiles are provided by OpenStreetMap public tile servers:

tile.openstreetmap.org

Use of these services is subject to OpenStreetMap's terms and policies.

1.3 Automatic Location Name Detection

City names, regions, and other geographic labels may be resolved using the Flutter Geocoding plugin:

pub.dev/packages/geocoding

2. Calculation Accuracy

All calculations provided by the app — including Uposatha dates, dawnrise times, sunrise/sunset, moon phases, Myanmar calendar dates, and related calculations — are provided for reference or educational purposes only.

No guarantees are made regarding accuracy, completeness, reliability, or suitability for any particular purpose.

These calculations should not be relied upon for critical, legal, ceremonial, navigational, medical, safety-related, or emergency purposes.

Users are encouraged to consult authoritative or qualified sources when accuracy is important.

3. No Warranty

This software is provided "AS IS", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement.

In no event shall the authors or contributors be liable for any claims, damages, losses, or other liabilities arising from the use of this software.

4. Children's Privacy

Our Service does not address anyone under the age of 16.

We do not knowingly collect personally identifiable information from anyone under the age of 16.

However, certain third-party services such as map, imagery, or geolocation providers may process limited technical information as required for their functionality.

5. Changes to This Privacy Policy

This Privacy Policy may be updated from time to time. Any changes will be reflected on this page.
