Privacy Policy

1. Information we collect

1.1 Location data

The App requests access to your device's precise or approximate location to:

• Detect your current city for weather and sun-position calculations.
• Calculate the sun's position along your route, from the departure and arrival points you enter.
• Power the Live Trip feature, which tracks your position during an active journey to alert you if the recommended side changes.

Location access is requested at the point of use and can be denied — the App remains usable without it, since you can still search for cities manually. If you deny it, features that depend on it (auto-detecting your location, Live Trip) will not run, but the App will not crash and everything else stays available.

1.2 Maps and route display

Trip results and the map picker display an interactive map provided by Google Maps Platform. To render it, Google receives the map area you are viewing and standard technical data about your device and network. The road route drawn on that map is computed by a separate routing service (see section 2), which receives only the departure and arrival coordinates of your trip.

Routes you have already viewed are cached on your device so the same trip does not have to be requested again. That cache holds trip coordinates only, stays on your phone, and is removed when you uninstall the App or clear its storage.

1.3 Camera

The App requests camera access for the Sun Tracker feature, which combines the camera viewfinder with your device's compass and orientation sensors to show you the sun's direction, and lets you take a photo. Camera access is used exclusively for this feature:

• The App does not record audio through the camera.
• The App does not upload, transmit, or store your photos on any server. Photos you save are written directly to your device's gallery and stay on your device.
• Access is optional and only requested when you open Sun Tracker. Denying it does not affect the rest of the App.

1.4 Motion and orientation sensors

Sun Tracker and the live compass read your device's accelerometer, magnetometer and orientation sensors to know which way you are facing. These readings are processed on your device in real time, are never recorded, and are never transmitted.

1.5 Advertising data (Google AdMob)

The App displays banner and rewarded video ads served by Google AdMob, which may collect and process:

• Your advertising identifier (Android Advertising ID), used to measure ad performance and, where permitted, personalize ads.
• Device and app information typically used for ad delivery and fraud prevention (device type, general region, app version).

In regions where consent is required, the App shows Google's consent form before any personalized ad is requested, and your choice is respected on every later session. You can also opt out of personalized advertising in your device settings (Settings → Google → Ads → "Opt out of Ads Personalization"), and reset or limit your advertising identifier at any time. This data is collected and processed directly by Google and its advertising partners under their own policies: Google Privacy Policy and how Google uses information from partner sites.

1.6 Notifications

If you enable notifications, the App schedules local, on-device reminders — for example, a reminder before a planned departure, or an alert during a Live Trip when the sunny side changes. These notifications are generated and scheduled entirely on your device; no notification content or scheduling data is sent to us or to any third party. You can disable them at any time from your device settings or from within the App.

1.7 Locally stored data

The App stores the following on your device only, using standard Android app storage, and never transmits it to us:

• Your recent and favorite trips (departure and arrival cities, transport mode, saved dates).
• App preferences (units, time format, default sun preference, language, notification settings).
• A cache of road routes you have already viewed, so they display instantly and work offline.
• Daily usage counters for Sun Tracker and Live Trip, used solely to apply their daily allowance.

This data is deleted when you uninstall the App or clear its storage. We have no server-side access to it.

1.8 Crash reports (Sentry)

When the App crashes or hits an unexpected error, it sends a diagnostic report to Sentry, so that we can find and fix the fault. A report contains:

• The error itself — its type, its message, and the stack trace showing which part of the code failed.
• The App version and whether the build is a release or a test build.
• Your device model, operating system version, language and time zone.
• The technical events immediately preceding the failure, which help reproduce it.

A crash report is not a record of your activity. It is only created when something goes wrong, and it carries no advertising identifier, no IP address, no screenshot, and none of your trips, photos, or saved preferences. We do not deliberately send your location; be aware, however, that if a map, routing or weather request is what failed, the technical details of that one request can include the coordinates it was made with.

Reports are stored by Sentry on servers in the European Union and are automatically deleted after 90 days. Sentry's policy is available at sentry.io/privacy.

2. Third-party services

SunSide has no servers of its own. To answer a request it calls the services below directly from your device, and sends each one only what that service needs:

None of these services receives your name, email address, or any account identifier from us. Map data is © OpenStreetMap contributors, and route geometry is provided by the OSRM project.

3. How we use information

We use the information described above solely to:

• Calculate and display sun-position recommendations for your trips.
• Provide weather context relevant to your trip.
• Draw your route on a map.
• Operate optional features you choose to use — Sun Tracker, Live Trip, notifications.
• Display and measure ad performance.
• Diagnose and fix crashes, using the reports described in section 1.8.

The App contains no analytics or usage-tracking SDK: nothing measures which screens you open, how long you stay, or what you tap, and we do not build a profile of you. Crash reporting is the single exception, and it is not a form of tracking — it produces a report only when the App fails, never during normal use. We do not sell your personal information, and we do not use your data for any purpose beyond operating the App's own features.

4. Data retention

• Coordinates used for a single request (map, route, weather, geocoding) are not stored by us after the request completes.
• Trip history, favorites, cached routes, and preferences stay on your device until you delete them in the App or uninstall it.
• Crash reports are held by Sentry on EU servers for 90 days, then deleted automatically.

5. Children's privacy

SunSide is not directed at children under 13, or the relevant minimum age in your jurisdiction, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can remove it.

6. Your rights

Depending on where you live, you may have the right to access, correct, or delete personal data we hold about you, and to object to or restrict certain processing. Since most data described here is stored locally on your device, you can exercise most of these rights directly by clearing the App's data or uninstalling it. For anything processed by our third-party providers — Google Maps, Google AdMob, Sentry — please also refer to their policies linked above, or contact us and we will help where we are able to.

7. Security

All requests the App makes leave your device over encrypted HTTPS connections. Beyond that, we rely on the security measures provided by Android, Google Maps, Google AdMob and Sentry to protect the data described in this policy. No method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.

8. Changes to this policy

We may update this policy from time to time. Changes will be posted at this same address with an updated "Last updated" date. Continued use of the App after a change means you accept the revised policy.
