1. Zero Persistent Server-Side Storage
RouteFlow Pro operates strictly as a stateless client-side application. When you input postcodes, customer names, telephone numbers, or delivery notes, this information is held strictly within your local browser session. LZW Digital does not store, harvest, record, or retain any customer addresses, personal names, or route records on any server.
2. Third-Party Service Providers & APIs
To calculate road coordinates and display delivery maps, this tool connects to the following audited third-party services:
- Postcodes.io: A free UK postcode lookup service used strictly to translate outward/inward UK postcodes into approximate latitude/longitude coordinates. No customer names or phone numbers are ever transmitted.
- OSRM (Open Source Routing Machine) & OpenStreetMap: Provides live UK driving durations and road network routing across motorways and A-roads.
- OpenStreetMap: High-resolution street map tiles loaded securely to display geographic pins across the UK road grid with zero tracking.
- Google Maps Navigation, Apple Maps & Waze: Navigation destinations are passed directly to your chosen GPS navigation app via standard URL schemes.
- jsPDF & Pure PHP Engine: Manifests are assembled on demand and streamed directly to your device as downloadable files.
3. Data Security & Local Backup Files
When using the "Save Route" backup tool, an encrypted structured JSON payload (.rfp) is saved directly to your local computer or phone. Uploading this file performs rigorous schema validation and geographic UK boundary checks to safeguard against cross-site scripting or malicious payloads.
4. Operator Responsibilities
Fleet operators using RouteFlow Pro are responsible for ensuring they have appropriate consent from customers before transmitting SMS or WhatsApp arrival notifications. RouteFlow Pro is provided as a high-performance productivity tool by LZW Digital.
