# Terms of Service, Disclaimer, and Privacy Policy *Last updated: March 2026* Welcome to this multi-stop route planning and itinerary optimization application (the "App"). This document sets forth the legally binding Terms of Service, Disclaimer, Limitation of Liability, and Privacy Policy governing your access to and use of the App. By downloading, installing, accessing, or using the App, you acknowledge that you have read, understood, and agreed to be bound by these terms. If you do not agree with any part of these terms, do not install or use the App, and delete it from your device immediately. --- ## 1. Description of the Service The App provides computational path-sequencing and route-planning utilities designed to assist users in organizing multiple destination stops. The App utilizes mathematical algorithms (such as Traveling Salesperson Problem heuristics) to suggest theoretical orderings and distances. Features include: * Multi-point location marking and automatic stop re-sequencing. * Trip status tracking (marking stops as "Visited" or "Pending"). * Handoff and deep-linking to external third-party navigation providers (such as Apple Maps or Google Maps). --- ## 2. Safety Notice and Driving Disclaimer ### 2.1 Theoretical Routing Only All routes, estimated travel times, distance calculations, stop sequences, and navigation suggestions provided by the App are **purely theoretical algorithmic estimates**. They are generated for convenience and planning purposes only and do not account for instantaneous real-world hazards, emergency road closures, or physical vehicle limitations. ### 2.2 Strict Compliance with Traffic Regulations * **Road Safety First:** You must always prioritize personal safety, passenger safety, pedestrian safety, and general public safety above any suggestions provided by the App. * **Traffic Laws Supersede Suggestions:** Local traffic laws, posted speed limits, official road signage, dynamic overhead warnings, lane closures, and traffic police directions always supersede any algorithmic route or order suggested by the App. * **No Distracted Driving:** You expressly agree **not** to interact with, configure, enter addresses into, or manipulate the App while operating a moving motor vehicle, motorcycle, bicycle, electric scooter, or any other transport machinery. Any route planning or marker management must occur while parked safely in a legal parking area. ### 2.3 Environmental and Route Realities The developer does not warrant or guarantee that suggested routes are accessible, safe, legal, paved, or free from hazards. Real-world conditions change continuously due to: * Dynamic traffic congestion, accidents, and sudden blockages; * Weather events, flooding, icy surfaces, and road erosion; * Construction zones, detours, and road works; * Physical road attributes (such as low bridges, weight limits, narrow alleyways, or one-way street directions). --- ## 3. Comprehensive Limitation of Liability To the fullest extent permitted by applicable law, the developer, affiliates, and licensors shall **NOT** be held legally or financially liable for any direct, indirect, incidental, special, exemplary, punitive, or consequential damages arising out of or related to your use of or inability to use the App, including but not limited to: 1. **Traffic Incidents and Bodily Harm:** Any vehicular collisions, accidents, personal injuries, fatalities, or property damage resulting from traveling along suggested routes or interacting with the App. 2. **Fines and Citations:** Traffic violations, speeding penalties, illegal turn citations, toll charges, or license point deductions. 3. **Logistics, Courier, and Delivery Losses:** Delayed deliveries, expired food items, missed delivery time-windows, canceled shipments, logistics fines, contractual breach charges, customer compensation claims, or platform rating degradations. 4. **Commercial and Financial Loss:** Loss of revenue, business profits, client accounts, operational downtime, or business interruption. 5. **Loss of Data:** Accidental deletion, data corruption, or hardware malfunctions occurring on your mobile device. You use the App entirely at your own risk. The App is provided strictly on an **"AS IS"** and **"AS AVAILABLE"** basis without warranties of any kind, whether express, implied, statutory, or otherwise. --- ## 4. Third-Party Services and Mapping Providers The App allows users to initiate turn-by-turn navigation via external third-party services, including Apple Maps and Google Maps. * The developer does not operate, control, maintain, or verify the routing engines, voice guidance, live traffic data, or satellite imagery provided by these third-party platforms. * Launching and using external mapping applications is subject exclusively to the respective terms of service and privacy agreements of those third-party providers. The developer assumes no responsibility for third-party service outages, routing failures, or inaccuracies. --- ## 5. Privacy Policy We are committed to maintaining the privacy and security of your personal information. ### 5.1 Location Data Processing * **Usage Purpose:** The App requests location permissions (`When In Use`) solely to pinpoint your current location on the map, assist in placing waypoints, and calculate optimal distances relative to your starting location. * **No Background Tracking:** The App does not monitor, track, or collect your geographic location while running in the background. * **No Remote Transmission:** Your coordinates are processed on-device. We do not transmit, log, or store your real-time coordinates on external servers. * **No Commercialization:** We do not trade, sell, lease, or monetize your location data with advertising brokers or data aggregators. ### 5.2 Local Storage of Trip Data All destination pins, custom labels, order sequences, and status flags ("Visited" vs. "Pending") are stored exclusively within local on-device application storage (such as Apple's local file system or Core Data). This information remains entirely on your physical device and can be permanently purged by clearing application data or uninstalling the App. ### 5.3 Personal Identification and Accounts * The App does not require registration, login accounts, telephone numbers, or email credentials to access basic routing functionality. * We do not collect names, government IDs, payment cards, or sensitive biographical details. --- ## 6. Intellectual Property and Permitted Use All software code, user interface designs, graphical assets, algorithms, and documentation associated with the App remain the intellectual property of the developer. You are granted a limited, revocable, non-exclusive, non-transferable license to use the App for personal or business planning purposes. You may not decompile, reverse-engineer, disassemble, modify, or create derivative works from the application binaries. --- ## 7. Modifications to This Agreement The developer reserves the right to revise or update these Terms of Service, Disclaimer, and Privacy Policy at any time without prior individual notice. Any revised version will take effect immediately upon being posted at this URL. Continued use of the App after such amendments indicates your formal acceptance of the modified terms. --- ## 8.
