Terms of Use

1. Service Description and Features

1.1 PulveCast is a hybrid mobile and web application designed as a co-pilot for agricultural spraying operators (drones, tractors, and uniports).

1.2 The application offers and aggregates the following features and information:

• Weather Forecasts: Temperature, wind speed and gusts, relative humidity, dew point, atmospheric pressure, cloud cover, precipitation probability/volume, and visibility.
• Calculated Agricultural Metrics: Delta T (evaporation rate indicator), spray drift risk (Spray Drift), and thermal inversion risk.
• Satellite and GPS/RTK Parameters (drones): Real-time estimation of visible satellites (GPS, GLONASS, Galileo, Beidou systems) and monitoring of geomagnetic activity (KP Index) to identify risks of electromagnetic interference in drone compasses and RTK positioning. These metrics are hidden for tractor/uniport mode.
• Equipment & Crop Presets: Equipment type selection (drone or tractor/uniport), preconfigured operational limits for popular drone models (e.g., DJI Agras, XAG), and target crop presets.
• Operation Planning Tools: Customizable checklists, spray mixture calculator, and wind direction compass.

1.3 The application is provided under a freemium model. Core weather features are free. PulveCast Pro is an auto-renewable monthly subscription purchased through Apple App Store or Google Play, unlocking premium tools (such as altitude wind profile, favorites, hourly table forecast, crop presets, premium weather sources, and wind compass).

1.4 PulveCast does not require user accounts or sign-in. Preferences are stored locally on your device.

2. Full Disclaimer of Warranties ("As Is")

2.1 PulveCast and all information and features contained therein are provided on an "as is" and "as available" basis, without warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement.

2.2 While we pull data from reputable weather and aerospace services (including Open-Meteo, WeatherAPI, Apple WeatherKit, GFZ Potsdam, and Celestrak), the developer **does not warrant** the accuracy, completeness, timeliness, availability, or reliability of such information. Actual weather conditions can change rapidly and may differ significantly from forecasts.

2.3 Calculations provided by the app (such as thermal inversion risk, Delta T, and drift index) are **approximate mathematical models** based on forecasts or historical datasets and should not be relied upon as absolute safety guarantees or professional agricultural advice. It is highly recommended to perform real-time physical measurements in the field using calibrated instruments (anemometers, psychrometers, etc.) before starting the spray operation.

3. User Responsibility

3.1 By using PulveCast, you agree to assume **sole, exclusive, and unrestricted responsibility** for flight safety, drone operation, flight paths, chemical/fertilizer handling, application, and all decisions made based on the information provided by the application.

3.2 You acknowledge that drone operations and chemical spraying are subject to strict local regulations, civil aviation laws (e.g., ANAC and DECEA in Brazil, FAA in the US), and environmental/agricultural rules. It is your sole responsibility to know, obtain necessary licenses, and comply with all applicable laws before operating your equipment.

4. Strict Limitation of Liability

4.1 Under no circumstances shall the application developer (Renan Rafael Bertoldo) or contributors be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of or inability to use PulveCast.

4.2 This limitation of liability applies to, but is not limited to:

• Drone crashes, flyaways, collisions, loss of control, or hardware/sensor malfunctions;
• Physical damage to the aircraft, batteries, spraying payloads, or associated ground equipment;
• Property damage, third-party bodily injury, or death caused by the drone operation;
• Partial or complete crop loss, plant death, chemical burn, or inefficiency of the applied mixture;
• Damages arising from spray drift affecting neighboring farms, crops, water sources, wildlife, or protected areas;
• Fines, penalties, or regulatory sanctions imposed by aviation or environmental authorities due to non-compliant operations;
• Service interruptions, loss of user data (such as saved checklists or favorites), or database failures.

5. Suspension, Discontinuation, and Deletion of the App Without Prior Notice

5.1 The developer reserves the right, **at any time, in their sole discretion, and without prior notice, notification, or justification**, to modify, suspend, limit, interrupt, or **permanently delete the application, website, servers, databases, or any associated services**, in whole or in part.

5.2 You agree and acknowledge that the discontinuation, termination, or deletion of the application or its servers **will not entitle you to any damages, compensation, or refunds from the developer**, beyond remedies that may be available under Apple App Store or Google Play policies for auto-renewable subscriptions. Purchases inside the application represent a limited license to use Pro features while the subscription is active and while the application remains available.

6. Intellectual Property

6.1 PulveCast, including its brand, logo, source code, UI design, calculation algorithms, texts, images, and documentation, is the exclusive property of Renan Rafael Bertoldo and is protected by copyright and intellectual property laws.
