No subscription — own your data forever. Reminders that actually work. ServiceVault is the privacy-first, offline vehicle maintenance and fuel logger built for car owners, motorcycle riders, and fleet enthusiasts who are tired of recurring monthly subscriptions and privacy-invasive cloud accounts. Every record you log, every receipt photo you attach, and every dollar you spend remains strictly on your device. Never trapped in a proprietary cloud, never sold to advertisers, and never held hostage behind a subscription. KEY FEATURES: • UNIFIED DIGITAL GARAGE Manage all your vehicles in one place — cars, trucks, motorcycles, and daily drivers. Track make, model, year, VIN, license plate, custom photos, and live odometer readings in either miles or kilometers. • REMINDERS THAT ACTUALLY WORK Never miss an oil change, tire rotation, brake inspection, or registration renewal again. ServiceVault monitors both calendar intervals (e.g., every 6 months) and mileage thresholds (e.g., every 8,000 km) and sends reliable, native local notifications when items are Due Soon or Overdue. • DETAILED SERVICE HISTORY Log maintenance with preset categories or custom service types. Record service dates, exact odometer readings, parts and labor costs, personal notes, and photo receipts or invoices. Search and filter your vehicle's entire history instantly. • COMPREHENSIVE FUEL LOG & EFFICIENCY Record fill-ups with volume, cost, and full-tank tracking. ServiceVault automatically computes real-world fuel economy (MPG, L/100km, or km/L) between fill-ups and provides a rolling average efficiency to help you monitor vehicle performance over time. • 100% UNRESTRICTED PDF & CSV EXPORTS Need to show maintenance history to a buyer or mechanic? Generate clean, professionally formatted, high-contrast PDF reports and CSV spreadsheets with a single tap. Exporting is completely free and unrestricted for everyone — because your vehicle data belongs to you. • OFFLINE BACKUP & RESTORE Export encrypted JSON backups of your complete garage data anytime. Share backups via AirDrop, save to Files, or email them to yourself for safe keeping. Restore your records on any iOS device in seconds. • LIGHT & DARK MODES Crafted dark-mode-first with high-contrast typography, deep carbon tones, and refined amber accents. Switch between Night, Day, or System appearance to match your personal style. • HONEST, TRANSPARENT PRICING Start completely free with one vehicle and initial log entries. Unlock unlimited vehicles and unlimited lifetime logging with a single, fair, one-time purchase. No monthly fees, no yearly renewals, and no surprise charges. PRIVACY BY DESIGN: • No user account or login required • No internet connection required to use the app • No analytics, telemetry, or third-party trackers • All data and attachments stay 100% offline on your device Questions or feedback?
