MyWarranties is the privacy-first warranty tracker and purchase organizer. No accounts, no cloud, no tracking — your data stays 100% on your device. CORE FEATURES WARRANTY & PURCHASE TRACKING Add any product with name, brand, purchase date, warranty period, price, store, and notes. The app automatically calculates the expiration date and assigns a real-time status: Active, Expiring Soon, or Expired. Archived items are handled automatically so your dashboard stays clean. RECEIPT & PRODUCT IMAGE MANAGEMENT Upload photos of your receipts and products directly into the app. Images are compressed and optimized to save space while keeping them sharp and readable. Supports both product photos and receipt/invoice images. You can also search the web for product images via DuckDuckGo and pick the best one with a single click. SMART EXPIRATION ALERTS Never miss a deadline again. Receive Chrome notifications at 30, 15, 7, 5, and 1 day(s) before your warranty expires. Each product can have notifications turned on or off individually. A snooze feature lets you pause reminders when needed. The service worker runs daily in the background, so alerts work even when the extension is closed. VISUAL STATUS DASHBOARD Instantly see your warranty health with color-coded cards and a stats bar showing Active, Expiring Soon, and Expired counts. Click any stat to filter the list instantly. Cards are expandable to show full details, images, and action buttons. POWERFUL SEARCH & SORTING Find anything in seconds with real-time text search across product names and brands. Sort your list by date added, product name, expiration date, or price — cycle through with one click. BACKUP & PORTABILITY Export your entire database to a JSON file anytime. Import it back on any Chrome browser or profile. Perfect for switching computers or creating backups. The import process validates data integrity and preserves your information safely. IMAGE VIEWER Browse uploaded images in a fullscreen overlay with keyboard navigation (arrow keys and Escape), dot indicators, and image counter. Perfect for zooming into fine print on receipts. BRAND SUPPORT SEARCH One-click access to Google search for your product's brand support page, localized to your browser language. THEMES & LAYOUT Choose between Light, Dark, or System theme. The interface adapts automatically. Works as a compact popup or a full-page dashboard. Open in a new tab anytime for a bigger workspace. HOW TO USE 1. Open the extension from your Chrome toolbar. 2.
