1. What This App Is

Ancient Coin Cabinet is a personal coin catalog. It helps you organize, photograph, and document coins you own.

All data is stored locally on your device. The app does not use accounts, cloud storage, or tracking. It works fully offline once loaded.

This app focuses on organization and reference. It is not a pricing guide, marketplace, or authentication service.

This app does NOT:

Estimate market value or provide appraisals
Sync data across devices automatically

2. Cabinets (Collections)

A cabinet is a container for coins. Think of it as a folder or collection.

You can create cabinets to represent:

Historical eras (e.g., "Roman Imperial", "Byzantine")
Themes (e.g., "Silver Denarii", "Emperors I Like")
Storage locations (e.g., "Display Case A", "Safe")

You can create, rename, and delete cabinets at any time.

Important: Deleting a cabinet permanently deletes all coins inside it. Before deletion, the app offers you a chance to back up the cabinet as a file. This backup is optional but recommended.

3. Adding a Coin

To add a coin, open a cabinet and select "Add Coin" from the menu or button.

Images:

Obverse (front) and reverse (back) images are required
You can add additional images for edge views, packaging, or details
Images are stored at full quality on your device

Fields:

All text fields are optional. Fill in what you know or what is useful to you:

Denomination: The type of coin (e.g., Denarius, Drachma)
Ruler/Emperor: Who issued the coin
Mint: Where it was minted
Metal: Gold, Silver, Bronze, etc.
Weight, Diameter: Physical measurements
Obverse/Reverse Details: Descriptions of imagery or inscriptions
Notes: Any other information you want to record

Fields like cost and perceived value are optional and personal. The app does not calculate or suggest values.

Leaving a field blank is allowed. You can edit everything later.

4. Editing a Coin

To edit a coin, open it and select "Edit" from the menu.

You can change any field or replace images. When you save, the previous values are overwritten.

Important:

Changes are permanent once saved
Edits persist after reload
Editing one coin does not affect other coins
Editing does not affect existing backups unless you export again

5. Organizing & Viewing Coins

Coins appear inside the cabinet they belong to. You can view them as a grid or scroll through details.

Sorting:

Use the Refine menu to sort coins by emperor, mint, date added, or inventory ID.

Stats (Optional):

If you enable Stats in Settings, you can view summaries like metal distribution, ruler chronology, and timelines. Stats are descriptive only. There are no rankings, scores, or goals.

6. Backups & Imports (Important)

Backups are files saved to your device. The app cannot recover data without a backup.

There are two types of backups:

A) Cabinet Backup

Backs up one cabinet and all coins inside it
Used to move or restore a specific cabinet
Importing a cabinet backup does NOT overwrite other cabinets
Access this from the cabinet's 3-dot menu

B) Full Collection Backup

Backs up all cabinets and all coins
Used for device changes, reinstalls, or full restore
Importing a full backup restores the entire collection
Access this from Settings → Backup / Import

How backups work:

Backups are JSON files saved wherever you choose (Downloads, Cloud Drive, etc.)
Importing restores data exactly as it was when the backup was created
You are responsible for storing and organizing backup files

Recommendation: Export a full collection backup regularly, especially before major changes or device updates.

7. Stats & Insights (Optional)

Stats are disabled by default. You can enable them in Settings.

What Stats show:

Coin counts by metal, ruler, dynasty
Chronological timelines
Summaries of your collection

What Stats do NOT show:

Market data or pricing
Rankings or performance indicators
Comparisons to other collections

All statistics are computed locally from your data. Nothing is sent or compared externally.

8. Your Data & Privacy

All cabinets, coins, and images are stored on your device using browser storage (IndexedDB). Nothing is uploaded to servers or shared.

Important:

Clearing browser data deletes your collection
Uninstalling the app deletes your collection
Backups are your responsibility

The app does not send data anywhere. It does not track usage, create accounts, or connect to external services.

9. What This App Does Not Do

This app is intentionally focused. It does not:

Estimate market value or provide appraisals
Connect to marketplaces or facilitate selling
Authenticate coins or verify grading
Sync data across devices automatically
Require accounts, logins, or subscriptions
Include social features, public profiles, or feeds
Track your activity or send analytics

This is a personal cataloging tool. Your data stays with you.

💡 This guide is always available from the Menu. No setup required—just start adding coins.
