Read full description

Purchase Memory is your personal purchase history — one place to remember what you bought, where you bought it, and when. Instead of digging through different marketplaces, old receipts, screenshots, or invoices, Purchase Memory helps you build a searchable memory of the things you have purchased over time. IMPORT RECEIPTS Add purchases from your camera, photo library, or PDF files. Purchase Memory helps turn receipts into structured purchase information that you can review before saving. FIND WHAT YOU BOUGHT Search and browse your history by item, purchase, merchant, source, brand, category, date, and other purchase details. BUILD A LONG-TERM PURCHASE MEMORY Keep product names, merchants, prices, dates, discounts, order information, and receipt attachments together so they are easier to find later. SEE USEFUL MEMORY INSIGHTS Rediscover old purchases, frequently used merchants, repeat products, and how long your Purchase Memory has been growing. LOCAL-FIRST Your personal purchase history is designed to remain usable on your device. You can also use Purchase Memory locally without signing in. PREMIUM YEARLY Premium adds higher receipt-import capacity and optional encrypted cloud backup and restore, helping protect your Purchase Memory when moving to or recovering on another device. • Title: Premium Yearly • Length: 1 year • Price: shown in the app and on the App Store (varies by region) • Free includes up to 15 successful receipt imports per month • Premium includes up to 180 successful receipt imports per month Payment is charged to your Apple ID account at confirmation. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings → Apple ID → Subscriptions. Purchase Memory is not a budgeting or expense-tracking app. It is built around a simpler question: “I bought this before — where did I buy it?” Everything you’ve bought, remembered.
