For stamp collectors
A private, local catalogue for your philatelic collection. Design your own labels and print them on your own printer.
ClearBench is a native desktop app built for philatelists who want their collection, and what it's worth, to stay theirs alone. Country, year, denomination, Scott / Michel / SG numbers, perforation, watermark, gum, condition. No cloud account. No subscription database. No shared list of who owns what.

Three things, done well.
ClearBench isn't trying to be a Scott catalogue, an auction tracker, and a cloud sync product all at once. It's a focused desktop app that does the three things philatelists actually need.
Catalogue every stamp
Description, country, year, denomination, Scott / Michel / Stanley Gibbons numbers, design subject, perforation, watermark, gum, condition, errors and varieties, acquisition cost, current valuation, where it sits in the album. Your full philatelic record on your machine.
Design your own labels
Six starting templates from clean to ornate. Twelve bundled fonts. Full control over every field, font size, and alignment. Output a sharp PDF at exact size and print it on your own printer.
Keep it off the cloud
Your stamp collection isn't searchable on anyone's website. ClearBench stores everything on your computer. No upload, no telemetry, no analytics on what you own or what it's worth.
Selling stamps? Built for that too.
Track stock separately from your personal collection, scope to the active show, record sales as they happen, print label sheets and price tags. Same app, same privacy, no extra purchase. ClearBench is built for how stamp dealers actually work.
Track stock at every show
One inventory list across every stamp show and bourse. Filter to what's on the table, scan a SKU, mark it sold. Catalogue number, condition, asking price all on the table-side device.
Record sales as they happen
A sale is two clicks: pick the stamp, enter the price. ClearBench logs the date, the show, the buyer (optional), and the actual price paid. End-of-show reports show what sold, by show, by country, by margin.
Print price tags + bulk-import
The same label engine prints price tags for every stockbook page or display sheet. Drop in a CSV from Excel to bulk-load a fresh table; round-trip back any time.
Built for philately, not generic cataloguing.
ClearBench knows what a stamp actually carries on its label and in its record. The fields are the ones any serious philatelist would expect to see.
Your collection isn't searchable on anyone's database.
A serious philatelic collection, particularly one with rarities or classic-era material, is exactly the kind of asset you don't want listed somewhere a third party can read or accidentally leak. ClearBench's privacy architecture isn't a marketing line. It's the only sensible default for a philatelic catalogue.
Stored on your device only
Every stamp, scan, catalogue number, and valuation sits on your computer. No upload, no copy on any server, no third-party access, including ours. We literally cannot read your collection.
No analytics on your records
No telemetry on what you catalogue, photograph, or value. We don't track which stamps you collect or what you paid for them.
Backups stay yours
Full-catalogue backups are plain .clearbench JSON files you save where you want: your hard drive, an encrypted external, your own cloud. For day-to-day work, export any collection straight out to CSV, Excel, plain text, or a vCard for contacts, then round-trip back in after a bulk edit. The format is documented and stable.
No lock-in
If we vanish tomorrow, your collection is still yours, in a format you can re-import into other tools. The .clearbench backup file is plain JSON that opens in any text editor; the CSV, Excel, and plain-text exports open in tools you already have.
Labels that earn their place beside the stamp.
Six bundled templates from clean to ornate, with full control over font, size, alignment, and prefix. All text rendered as SVG paths via opentype.js, pixel-accurate at every zoom and on every printer.

Common questions from stamp collectors.
Does it handle Scott, Michel, and Stanley Gibbons numbers?
+
Yes. Each stamp has separate Scott number, Michel number, and Stanley Gibbons number fields, plus a generic Collection number for any catalogue ClearBench doesn't break out by name (Yvert, Sakura, ANK, etc.). All four are free-text so any prefix or suffix notation fits, like Scott C13, Michel Bl. 5, SG 75a, etc. Filter and search work across every catalogue identifier.
Can I import from StampManage, EzStamp, or a spreadsheet?
+
A direct StampManage or EzStamp sync isn't built. Those products store data in their own formats and a live integration would compromise the privacy model. ClearBench imports from CSV instead. Export your existing catalogue to CSV from whatever tool you use today, drop it into ClearBench's per-collection import wizard, and the columns map onto the matching fields. Round-trip out to CSV any time.
How does it handle perforations, watermarks, and varieties?
+
Perforation, watermark, and gum are dedicated free-text fields so any standard notation works (Perf 12 x 11.5, comb perf 12, multiple watermark, original gum, regummed). Errors and varieties have their own field for the headline detail (inverted centre, missing perf, plate flaw 4-pane), and the catalogue's free-form Notes field is the right home for longer variety descriptions.
What about stamp scans? Where do they live?
+
Drag scans from your computer straight onto a stamp: front, back, multiples, full sheet shots if you want them. iPhone HEIC photos work without any conversion step once they're on your computer. Everything's stored locally; nothing's uploaded anywhere. The first image on each stamp becomes the cover image you see in the catalogue, and you can swap it any time.
Can I track valuations over time?
+
Yes. Each stamp has acquisition cost (what you paid), current valuation, valuation date, and a notes field for the source (Scott catalogue value, Michel value, dealer estimate, recent auction comp). The Stats dashboard tracks total cost vs total estimated value across the whole collection, with monthly snapshots so you can see the trend. All numbers are local, so no third party sees what you paid or what your collection's worth.
Does it support covers, postal history, and revenue stamps?
+
Yes. The Condition field includes 'on cover / piece' and the Description, Series, and Notes fields are free-text. They happily accept covers, postcards, postal stationery, and revenues. There's no separate covers section yet because the same fields cover (so to speak) most of the philatelic spectrum. Cancellation detail goes in the Condition notes field.
