finally in your pocket.
BrassKeep is the private firearm logbook for collectors and range shooters. Every safe, every session, every round — beautifully tracked. Never shared.
Coming soon to the App Store · Free to start
Your safe, secured.
Serial numbers masked until Face ID. Photos, attachments, round counts, maintenance — every firearm, organized.
Your log, automated.
Apple Watch shot timer, drill builder, USPSA scoring, ammo cost-per-round. Range trips tracked without paperwork.
Your privacy, respected.
No ads. No data sold. No marketplace. Free tier stays on-device — we don't even have a copy of it.
THE SAFE
Every firearm.
Beautifully kept.
Make, model, caliber, optic, serial, purchase date, photos, attachments, round count. For every firearm you own — at your fingertips, but locked behind your face.
- Serial numbers masked at rest. Face ID to reveal.
- Per-firearm round-count and service history.
- Cleaning & spring-change reminders driven by use.
- One-tap insurance manifest export.


THE LOG
The shot timer
you don't have to bring.
Range sessions, drill sessions, shot-timer runs — in the phone and the watch you already wear. Pre-built scoring for time, accuracy, USPSA hit factor, and pass/fail standards.
- Apple Watch shot timer. Mic on-device, never uploaded.
- Build custom drills with stages, goals, and pass times.
- Every round tied to the ammo lot it was fired from.
- Cold-score, hot-score, and per-stage splits.
THE SHOT TIMER
Hardware-grade timer.
No hardware required.
Sample-accurate splits off the audio hardware clock. Adaptive noise rejection so the next lane doesn't false-trigger. Spectral filtering so the timer's own beep doesn't log as shot #1. Built for the bay, not the bench.
- Live Fire auto-detection with crest gate + adaptive noise floor.
- Dry Fire par + auto-repeat with rep counting — no mic permission.
- RO voice cadence: "Shooter ready… Standby…" before the beep.
- Indoor / Outdoor / Quiet presets. Stop after N shots (Bill, El Prez).

ANALYTICS
Every range trip,
measured.
Skill score, pass rate, cost-per-round. Across drills, across time windows — 7 days to all-time. Know if you're actually improving, not just hoping. Your last 100 rounds bought +3% accuracy at $0.23 a round. You should know that.

PRIVACY · ON PURPOSE
The most private
app in the safe.
01
No ads. No trackers. No data sold.
Zero analytics SDKs in the build. No Facebook pixel, no Google tag, no Mixpanel, no third-party tracking of any kind. You're a customer, not a product.
02
On-device by default.
The free tier never touches our servers — your records stay on your iPhone. The microphone is used only by the watch shot timer, processed locally, never uploaded.
03
Yours to delete in 30 days.
Paid-tier cloud sync runs on a U.S. backend with per-user row isolation. Tap Delete account and it's gone in 30 days — backups included. No ghost profile.
04
Not a marketplace. Ever.
Our Terms prohibit using BrassKeep to facilitate the sale, transfer, or conveyance of a firearm, accessory, or round. This is a logbook. That's the whole product.

FAQ
Good questions.
Where does my data live?
On the free tier, exclusively on your iPhone. On the Armory tier, on BrassOps LLC's U.S.-based backend (Supabase) with per-user row-level security. Serial numbers are masked at rest server-side and only revealed locally after biometric auth.
What happens if I delete the app or my account?
Free tier: gone with the app. Paid tier: tap Delete account in Settings. Server-side data is purged within 30 days, including backups. No ghost profile.
Why does BrassKeep need the microphone?
Only for the Apple Watch shot timer. Audio is processed on-device to detect shot reports during a run, then discarded. It never leaves your wrist.
How does AI target analysis work?
You take a photo of your paper target. The image is uploaded to a private storage bucket and analyzed server-side via the Claude API. No AI credentials live on your phone. Results attach to the session automatically.
Is BrassKeep a marketplace?
No, and the Terms of Service explicitly prohibit using it as one. BrassKeep does not facilitate sales, transfers, or trades of any firearm, accessory, or round.
Who builds it?
BrassOps LLC, a U.S.-registered company in New Jersey. Built by firearm owners who got tired of tracking their own round counts in a spreadsheet.
Your collection
deserves better
than a notes app.
Free to start. $6.99/month for Armory. $199.99 lifetime for the first 500. Coming soon to iPhone and Apple Watch.
