Privacy Policy

1. Introduction

This Privacy Policy applies to the SignalSpot mobile application by Mikael Tenshio.

SignalSpot is designed as a local-only app for manually saving places where mobile signal is strong, weak, unstable, or unavailable.

SignalSpot includes:

• Saved signal spots with place names, area notes, categories, carriers, network types, signal levels, tags, use cases, and history
• Optional local location capture when you choose to save coordinates for a signal spot
• Signal map, saved spots, carrier comparison, travel notes, and local data health views
• Local check reminders, dark mode, local JSON or CSV export, and local JSON import

SignalSpot does not require account registration, cloud sync, developer-operated remote storage, online analytics, advertising SDKs, or user tracking for its app features.

2. Signal Notes Stored Locally

SignalSpot stores its main app data locally on your device. Local data may include:

• Signal spot names, specific areas, categories, carriers, network types, signal ratings, distance labels, notes, tags, use cases, and favorite status
• Signal check history, last-checked labels, created timestamps, updated timestamps, and locally generated item IDs
• Travel signal notes such as route, location or area, carrier, network, signal level, time, and optional note text
• Settings such as default carrier, default network type, dark mode, reminder preference, notification permission state, location-saving preference, and export preference
• Local data health details such as spot count, travel note count, schema version, last save time, and local safety-backup status

This information remains on your device unless you edit it, delete it, export it, share it, import replacement data, clear app storage, or uninstall the app.

3. Optional Location Data

SignalSpot can request location permission when you use location-enabled features such as the map or saving coordinates with a signal note.

If you allow location access, SignalSpot may locally store:

• Latitude and longitude
• Approximate accuracy value
• Timestamp or checked-at value
• Whether the location came from Android geolocation or a browser geolocation fallback

Location saving is optional. You can save manual signal notes without allowing location permission, and you can turn off location data in local exports from the app settings.

SignalSpot does not upload your saved coordinates to developer-managed servers and does not download or estimate official carrier coverage maps.

4. Reminders and Notifications

SignalSpot includes an optional local check reminder so you can remember to update signal notes on your device.

On Android, reminder delivery uses local notification features on the device. In browser preview environments, notification behavior may use browser notification support when available.

Notification permission is requested only when needed for reminder features. If you decline or disable notification permission, reminders may be unavailable or limited by your device settings.

5. Imports, Exports, and Sharing

SignalSpot can create local JSON or CSV export files for your saved signal spots, travel notes, settings, and related metadata.

Exports may include location data if you keep the location export setting enabled. You can turn that setting off before exporting to remove saved coordinates from the exported file.

On Android, SignalSpot may write an export file locally and open the Android share sheet so you can choose where to save or send it. In browser preview environments, export may use a file picker or download fallback.

If you import a local JSON file, it may replace or update local SignalSpot data depending on the app flow available in your version. SignalSpot also creates local safety backups before destructive local data actions where supported.

Once you export, save, or share a file outside SignalSpot, that copy is controlled by you, your device, and the destination app or storage location you choose.

6. Third-Party Services

SignalSpot does not use a developer-operated account system, cloud database, remote API storage, online analytics SDK, advertising SDK, or user-tracking service for its app features.

SignalSpot may rely on platform and runtime services such as Android, Google Play, device WebView behavior, Capacitor, file pickers, local file APIs, share sheets, geolocation APIs, and local notification APIs so the app can install and run on supported devices.

App stores, operating systems, browsers, WebView components, device manufacturers, file managers, and destination apps may process technical information under their own terms and privacy policies.

If SignalSpot later adds analytics, advertising, cloud backup, account sync, or another external integration, this Privacy Policy will be updated to describe the changed data practices.

7. Permissions and Device Features

Depending on your device and app version, SignalSpot may use or declare:

• Location permission for optional local coordinate capture and map-related local signal notes
• Notification permission for optional local check reminders
• Local device storage for saved signal spots, travel notes, settings, backups, and import/export data
• FileProvider, filesystem, picker, and share features for local export, import, save, and share flows

The Android app is designed without the Internet permission for its local-only workflow. SignalSpot does not require camera, microphone, contacts, SMS, call-log, Bluetooth, or background tracking permissions for its core features.

8. Data Retention and Deletion

Locally stored SignalSpot data remains on your device until you edit it, delete spots or travel notes, reset sample data, clear local storage, import replacement data, clear app storage, reset your device, or uninstall the app.

Local safety backups, corrupt-data snapshots, or exported files may remain on your device until you remove them through the app, device settings, file manager, or selected storage destination.

Because SignalSpot does not use a developer-operated cloud backup or account service for its core workflow, deleted local data may not be recoverable unless you kept your own export or backup.

9. Children's Privacy

SignalSpot is not directed to children under 13. We do not knowingly collect personal information from children through a developer-managed account system for this app.

Because saved signal notes may describe homes, schools, travel stops, or other personal locations, you are responsible for choosing what place names, notes, and coordinates you save or share.
