Your collection, step by step

This app is completely free. No account is needed. Collections stay in this browser and device.

1. Create collections

Press + beside Collections. Select a game or enter your own. Keep multiple collections for one game or several games.

2. Add cards

Record name, reference, edition, language and variant. Quantities represent owned copies and your target. Missing copies are the shortfall to that target; duplicates are copies beyond the first for each record. Each record identifies a specific presentation, not a complete manufacturer catalog.

3. Keep a backup

Export backup downloads all collections as JSON. Import backup adds its collections without replacing existing ones; importing twice adds two sets of collections. Keep backups private. No data is sent to the channel.

Use from your browser

This is a website: open its HTTPS link in an up-to-date browser and use it without installing anything. It is designed for current Chrome, Edge, Firefox and Safari; actual tests for each browser will be documented before claiming compatibility. No guarantee covers every old version or in-app browser. If an app does not open the link correctly, use your usual browser.

Data belongs to this browser and website origin. Another browser or device has a separate inventory: export a private backup and import it to move your collection. Private browsing may delete data when closed. The Drive ZIP contains files and manuals; it is not the website’s working URL.

Optional home-screen shortcut

Once a verified HTTPS link is available, Chrome on Android offers Install app or Add to Home Screen. On iPhone Safari use Share → Add to Home Screen. Installation and offline use still require real device tests before release.

The demo is fictional. The app does not authenticate cards or estimate prices. Visit Radar de Cartas opens only the public channel and sends no collection data.

Charts and goals

The chart compares collected copies with the goal defined in your records. Surplus copies of one reference do not complete another missing reference. Goals by collection compares your collections. These figures describe your inventory, not a manufacturer’s complete catalog.

The same reference, edition, language and variant cannot appear twice within a collection. Edit its record to change quantities. An imported backup containing duplicate records or invalid quantities is rejected in full. If saved inventory is corrupted, changes are blocked and Export backup preserves the original file for recovery.

Recover damaged data

If saved inventory is damaged, the app blocks changes. Export backup downloads the unmodified original. Select a recovery backup lets you choose a valid backup; read the notice and confirm Recover using this backup. The app preserves the damaged original separately in the same browser before replacing it. If saving fails, no replacement is made. Then export a backup of the recovered inventory. This local copy of the original is also lost if you clear browser data.

If storage is unavailable, inventory cannot be loaded or exported and changes are disabled. Zero counts in the interface do not mean your collection is empty. Reopen the app when storage is available again. The app cannot recover data already deleted by the browser.

Photos and a collection album

When creating or editing a record, choose Take photo or Choose image. Camera availability depends on your browser and device; if it is not offered, pick a gallery image. JPG, PNG and WebP up to 20 MB are accepted. An optimized JPEG copy with a maximum side of 1600 pixels is created; the original stays unchanged. Select Album to view photos for the selected collection, with record quantities preserved.

Photos and inventory stay in this browser, using IndexedDB when available or smaller local storage as a fallback. A failed or full store leaves the earlier inventory intact and displays an error. JSON backups include images and may be large (imports up to 100 MB). Keep them private: photos may include people or surroundings. There is no synchronization or photo transmission to the channel or marketplaces.

Reading photo text

Read text in photo processes the copy on your device. The first read downloads reader assets from this same website. The current model is trained for English and can misread Spanish, names, numbers and other languages. Offline reading is not guaranteed. Check suggested names and codes and enter edition, language, variant and condition yourself. This is not certain card identification, authentication or finish/condition analysis.

Comparing prices

Compare prices shows the record details for confirmation and opens external Cardmarket searches for configured games or completed/sold eBay searches. Only selected search terms are sent; the photo stays here. No automatic numeric pricing service is connected. Check that each result has the same edition, language, variant and condition. An asking price does not prove a sale; shipping can change the comparison. Providers may request their own verification, which this app does not bypass.

Front, reverse and zoom

In Edit, choose Front or Reverse and attach the matching image. An album image opens the viewer; + and − adjust zoom between 100% and 300%. This does not authenticate a card or diagnose its condition.

Individual physical-copy records

Physical copies stores C1, C2 or your own local identifiers under a reference. Each may have its own condition, two photos, purchase price and market reference. An already owned untracked copy is assigned first; only when all are detailed does the owned quantity increase. A copy is not counted twice. Owned quantities cannot be lower than detailed physical-copy records.

Quick entry with review

Quick entry accepts up to 20 front photos, selected together or taken one at a time. Review next opens each record. Check identification and details before Save card. The next photo opens only after saving. Cancel retains pending photos in this session; closing or reloading loses photos that have not been saved.

Missing-card trade list

Export missing cards for trades downloads a CSV for the selected collection only: game, name, reference, edition, language, variant and missing copies. Photos, prices, physical-copy records and other collections are excluded. Check the file before sharing in case you entered personal information in a field. This is not a backup.

Amounts and sources

Prices are entered manually. Purchase prices belong to individual copies; market references may be entered for a card reference or a specific copy. Enter currency and date, and a source for every market reference. Blank means unknown, not zero. Different currencies are not automatically converted or combined. There is no automatic pricing API or guaranteed sale value.

Backup reminder

The website shows the last saved backup you confirmed and the last requested download. Export requests a download; check the file was saved before selecting I saved my backup. Later changes or seven elapsed days bring the reminder back. Confirmation refers to the exported inventory, not later edits. Private JSON backups include all photos, physical-copy records and amounts.

Download and privacy

The package contains only the beta application files and these manuals, with no real inventories, credentials, Drive folders or internal fixtures. A link to an individual file is not a folder link. Photos and inventory remain in your browser; the app cannot open other files on your device or Drive. Do not publish your private backups. Free website code can be copied; absolute copy prevention is not promised.

HTML or free installers

Use the HTML version directly in your browser without installation. Windows EXE and Android APK are separate options for this completely free beta. Each installation and browser keeps its own local data: there is no automatic synchronization. Export and import a private backup to move a collection. An Android package does not install on iPhone; browser use depends on compatibility, with specific Safari tests still pending.

Community feedback is welcome to improve the beta and work towards a final version, without a guaranteed date. Include version, device, browser, steps and outcome; do not publish personal data or backups.
