Features

Everything
a collector
actually needs.

📸
Photo logging

Attach a photo to every card. Images are compressed client-side before storage — no uploads, no external CDN, no size bloat.

🔖
PSA cert lookup

Enter a cert number and auto-fill card details straight from the PSA public API. BGS, SGC, and CGC get direct verify links.

📈
Collection analytics

A live chart tracks cumulative spend over time. Filter by 30, 90, or 180 days. See total invested, average card value, and trend.

⚡
Mobile-first

Built for your phone. Bottom tab navigation, swipe-to-close sheets, camera capture, and safe-area insets on all device sizes.

🔍
Search & filter

Search across name, set, source, and notes. Filter the grid by Raw or Graded. Results update instantly as you type.

🖥
Desktop layout

On wide screens the add form moves to a sticky sidebar. Your collection fills the main panel. Full keyboard support throughout.

Security

Built on real cryptography, not promises.

Every card in your collection is encrypted with AES-256-GCM using a key derived from your password via PBKDF2 with 100,000 iterations. Your data is unreadable without your password — including to the storage layer.

🔐
AES-256-GCM encryption
Cards are encrypted before storage using the Web Crypto API. A random 12-byte IV is generated per save.
🔑
PBKDF2 key derivation
Your password is never stored. A key is derived at login using PBKDF2 (SHA-256, 100k iterations) with a unique salt per account.
🏠
Stays in your browser
No server, no cloud sync, no telemetry. All data lives in the storage layer of the device you're using.
