About this app

Sterlina Gold is the app for physical gold investors — Sovereigns, Marengos, Krugerrands, bars and other investment coins — who want to know at any moment what it's worth, how much they're gaining, and when it's worth selling.

📈 YOUR PORTFOLIO, ALWAYS UP TO DATE
• Real-time gold price (€/g and $/oz) and portfolio trend, with high and low of the period
• Realistic sale value: customizable buy and sell spread, just like at a gold dealer
• Gain/loss for each item and on the total, updated to the live price
• Portfolio breakdown by type with a chart, and comparison against silver and Bitcoin

🪙 ALL YOUR ITEMS IN ORDER
• Sovereigns, Marengos, Krugerrands, Maple Leafs, American Eagles, bars from 1 g to 1 kg, and custom items
• For every purchase: date, price, seller, invoice number, photo and attached invoice
• Import an invoice with AI: take a photo and the items are recognized and added automatically
• Already have your collection on a spreadsheet? Import it in one tap: read locally on your phone, no limits
• Search, filters, multi-select, partial sales with history

🔔 SMART ALERTS
• Alert when gold rises above or falls below the threshold you choose
• Notification when one of your items moves into profit
• Customizable time window: get notifications only when you want them
• Notifications apply to your whole account: your choices follow you to every device
• Home screen widget: gold price and portfolio value at a glance

📄 DOCUMENTS & TAX
• Export your item list as a PDF with summary and chart
• Track the origin of each item — purchase, inheritance or gift — with the linked document
• Tax summary: annual overview of sales and purchases with an estimate of the substitute tax (26%) to support your tax return
• Document gallery: find and bulk-export invoices and attachments
• Backup and export your data at any time

🔒 SECURITY & PRIVACY
• PIN lock, fingerprint unlock and two-step verification to protect your account
• Your portfolio is readable only by your account: the database security rules enforce it, it's not just a promise
• Data encrypted and synced to the cloud: you'll find it on every device
• Spreadsheet import happens entirely on your phone, the file is never uploaded
• AI features use Google Vertex AI, which does not retain your documents nor use them to train its models
• No ads, no selling your data: the app is funded by the subscription alone
• Delete your account and data at any time, in one tap

🛠 TOOLS
