Introduction & Scope
Welcome to HolidayPacker.com (“HolidayPacker”, “we”, “our”, or “the Service”). This document governs the privacy architecture, data handling paradigms, and legal obligations applicable to any visitor using our real-time smart packing generator, meteorological gear reconcilers, and destination resource archives.
Data Controller Identification
HolidayPacker • Independent Operator (Sweden, European Union)
Sweden / EU
By accessing or interacting with our web application, you acknowledge the privacy practices articulated herein. If you do not accept these tenets, your sole recourse is terminating interaction with the generator.

Information We Process
Our guiding engineering directive is radical data minimization. We only evaluate parameters strictly necessary to generate accurate, carrier-compliant packing manifests.

Algorithmic & AI Packing Synthesis
HolidayPacker synthesizes personalized packing recommendations through a hybrid architecture combining rule-based deterministic calculations and privacy-preserving Artificial Intelligence (AI) generation:
1. Deterministic Rule Matrices
Local / PHP Fallback
Computes baseline garment and accessory counts based on trip duration, baggage weight modes, and microclimate formulas (e.g. UV index to sunscreen ratios, rain probability to waterproof layer needs).
2. AI Language Models (OpenRouter)
Zero-PII API
When active, our server proxies anonymized parameters (destination city, duration, travel vibe, baggage constraints, and weather forecast) to AI models to generate tailored, destination-specific item recommendations.
verified_user
Zero PII Transmission: No personal details, names, emails, IP addresses, or tracking identifiers are ever sent to AI providers. Furthermore, your trip parameters are never used to train or fine-tune public foundation models.
None of your specific list variations or customized item additions are linked to an individual consumer profile. When you toggle items on or off, updates reside strictly within your browser\
04
Microclimate & Location Data
To furnish realistic weather previews (highs, lows, precipitation probabilities, UV indices, and coastal sea temperatures), HolidayPacker directly interfaces with the privacy-focused Open-Meteo meteorological platform.
public
Centroid Queries
We query geographic city center coordinates from Open-Meteo geocoding, never hotel or residential addresses.
timer
Direct Edge Forecasts
Forecasts and sea surface temperatures are requested client-side without collecting tracking telemetry.
vpn_lock
Zero Origin GPS
We never transmit or solicit your current departure coordinate to third parties.

Third-Party APIs & Commercial Partners
HolidayPacker maintains high standards of commercial and technical disclosure. We will never hide monetized relationships or external data processors behind obscure legalese.
Open-Meteo Meteorological Services
Weather Partner
We utilize Open-Meteo (EU-based, Germany) for destination geocoding, multi-day weather forecasts, and coastal sea temperature data. Open-Meteo operates under strict GDPR compliance, requires zero user authentication cookies, and does not retain IP addresses or track visitor habits.
OpenRouter AI Services
AI Language Model
To generate intelligent, climate-aware packing advice, anonymized trip parameters are processed via OpenRouter API (utilizing OpenAI models). No personal identifiable information (PII) is provided to the model, and queries are subject to zero-data-retention for training purposes.
Google Analytics (GA4)
Web Analytics (Active / Planned)
We utilize Google Analytics 4 (Google Ireland Ltd. / Google LLC) to collect aggregated statistical measurements regarding web traffic patterns, popular destination searches, and platform stability. IP addresses are anonymized automatically by default, and analytical telemetry is strictly segregated from your personal packing checklists.
Amazon Services LLC Associates Program
Affiliate Network
We participate in the Amazon Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by linking to Amazon.com and affiliated sites. When you click an external link to purchase recommended packing cubes, sunscreen, or adapters, an affiliate tag informs the merchant of the referral. This process generates zero personal profile linkage on our platform and adds no supplementary fees to your purchase.
07
Data Retention & Erasure Schedules
Our lifecycle protocol ensures stale packing data dissolves systematically according to transparent timelines:
Dynamic
Weather Edge Cache
Live regional weather parameters are requested on-demand from Open-Meteo.
Local
Saved Packing Lists
Checklists and PIN caches persist exclusively in your device\
0 Days
Payment / PII Logs
Immediate zero-retention guarantee as this data is never collected or stored.

All communications between your device and HolidayPacker are fortified via modern TLS 1.3 cryptographic transport with HSTS enforcement.
