Kakuremi - KeePass Manager
YubiKey free. KeePass vault.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Free local-first KeePass (KDBX) vault for iPhone — offline, AutoFill & Face ID, no YubiKey needed. Got a YubiKey 5? Free NFC unlock (HMAC-SHA1). No cloud, no tracking.
YubiKey NFC unlock -- free. No paywall. No subscription required.
If you've been using KeePass on iOS, you already know the frustration: pay $15/year just to use the hardware key you already own, deal with AutoFill that crashes mid-login, or wonder why your app is connecting to URLs stored in your vault before you've even entered your password.
Kakuremi was built to fix all of that.
**YubiKey Challenge-Response -- Free, Forever**
Every KeePass-compatible iOS app locks YubiKey behind a premium tier. Kakuremi doesn't. Tap your YubiKey to unlock your database. That's it. No trial period, no feature gate, no annual fee. You bought the hardware -- you shouldn't have to rent the software to use it.
**A KDBX Engine That Won't Corrupt Your Data**
Kakuremi's core is written in Rust -- a memory-safe language that eliminates entire classes of bugs that plague traditional password managers. No buffer overflows. No use-after-free. No "my database won't open after the last update." Your vault is processed by a battle-tested engine that treats data integrity as non-negotiable.
Supported formats: KDBX 3.x and KDBX 4.x. Full compatibility with KeePassXC, KeePass2, and every standard-compliant KeePass client.
**AutoFill That Actually Works**
Kakuremi implements Apple's Credential Provider framework the way it was designed to work. No keyboard disappearing acts. No blank screens after device restart. No mysterious crashes when you need your password most. It fills credentials in Safari and apps reliably, every time.
**Local-First -- Your Vault Stays on Your Device**
Kakuremi has no accounts, no cloud sync, no telemetry, and no analytics. Your decrypted database exists only in memory and is zeroed when the app locks. The only network features are optional and off by default: website icons (only a site's domain is sent to Google's favicon service) and password breach-check (a partial, anonymized hash sent to Have I Been Pwned). Your passwords and vault data are never transmitted.

**Why "Kakuremi"?**
Kakuremi (Japanese: hidden form) refers to the art of concealment. Your secrets deserve to be invisible -- not locked behind paywalls, not leaked through network connections, not corrupted by fragile code. Just hidden, exactly where you put them.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New in 1.2:
• More reliable saving — edits to newly created and additional databases are always saved now, and your changes are never lost when the app locks in the background.
• Stronger privacy — passwords copied to the clipboard clear automatically and stay on your device, and Kakuremi hides its contents in the app switcher and behind system sheets.
• Clearer AutoFill — if saving a new login from AutoFill fails, Kakuremi keeps what you entered and tells you what happened instead of dropping it silently.
• KeePass 2.0 key files — databases that use a .keyx key file from KeePassXC or KeePassium now open correctly.
• Free trial on the yearly plan — the one-month free trial is now shown clearly on Kakuremi Pro (Yearly).
• Plus improved tag entry, a corrected "Recently Modified" sort, safer CSV export, and many stability and localization fixes.
As always: offline-first, KeePass-compatible, with free YubiKey 5 NFC support.
