A local-first KeePass (KDBX) password manager for iPhone -- works offline, with AutoFill and Face ID, compatible with KeePassXC and KeePass2. Opening your first database and editing your vault are free. YubiKey NFC unlock is included free -- no subscription. Kakuremi was built for one thing: a KeePass vault that stays yours. **YubiKey Challenge-Response -- Free, No Subscription** Enter your master password, then hold your YubiKey to the top of your iPhone over NFC -- the key is a second factor, not a replacement for your password. The hardware-key unlock is not time-limited, not gated, and not billed separately. Kakuremi uses HMAC-SHA1 Challenge-Response, the same scheme as the KeePass desktop apps. It works with NFC-capable YubiKey 5 Series models and the YubiKey NEO once an HMAC-SHA1 slot is configured (via the YubiKey Manager / Authenticator app). FIDO2/passkey-only keys -- such as the Security Key Series -- cannot unlock a database, because they do not implement HMAC-SHA1 Challenge-Response. **A KDBX Engine Written in Rust** Kakuremi's KDBX parsing and serialization are written in Rust, a memory-safe language chosen to reduce the risk of buffer-overflow and use-after-free bugs. Open KDBX 3.x (read-only) and KDBX 4.x; create, edit, and save in KDBX 4. Compatible with KeePassXC, KeePass2, and other standard-compliant KeePass clients. **AutoFill in Safari and in Apps** Kakuremi ships a native Credential Provider extension that works with AutoFill on current and older versions of iOS. Tap the key icon, choose Kakuremi, and pick the login you need. **Local-First -- No Accounts, No Cloud Sync** Kakuremi has no accounts, no sync service of its own, no telemetry, and no analytics. Your database is decrypted in memory and released when the app locks. An encrypted copy of your logins (used by AutoFill) and recent copies of your vault file stay in the app's own storage -- you can clear both in Settings. Offline by default. Apart from App Store purchase checks, Kakuremi goes online only for optional features you turn on: website icons (only the domain goes to Google), breach check (only a 5-character hash prefix goes to Have I Been Pwned) and PC Connection (Pro), which sends a login you choose to your PC, end-to-end encrypted, via our relay on Cloudflare. The relay deletes it once your PC receives it (180 seconds at most). Cloudflare's recovery log may keep an encrypted copy for up to 30 days, which neither Springhiker nor Cloudflare can read. PC Connection never sends your vault file. **What's Free** - Create or open one KeePass database (KDBX 4; KDBX 3.x read-only) - Create, edit, and organize entries, groups, and tags - YubiKey NFC Challenge-Response unlock - Face ID / Touch ID biometric unlock - iOS AutoFill (Credential Provider) - Store TOTP (2FA) secrets and view live one-time codes - Password generator - Search and Recycle Bin - View attachments - Password breach check (Have I Been Pwned) - Themes (Light / Dark / Warm) and 6 accent colors - Localized in 9 languages **Kakuremi Pro** For power users who want more: - PC Connection -- fill in logins in Chrome on your PC from Kakuremi on your iPhone (needs Kakuremi's Chrome extension) - Use more than one database - Add file attachments - Backup history & restore Pricing: a monthly or yearly subscription, or a one-time purchase. New subscribers get a 1-month free trial on the yearly plan; the subscription then renews at the yearly price unless it is canceled at least 24 hours before the trial ends. Prices for your region are shown on this page. **Why "Kakuremi"?** Kakuremi (Japanese: hidden form) refers to the art of concealment. Your secrets deserve to be invisible -- no account to sign into, no copy of your vault on our servers, no fragile code to corrupt them. Just hidden in the file you chose.

Compare electricity and natural gas rates across Pennsylvania and switch to a cheaper energy supplier — GridScout PA does the shopping for you. It pulls rates straight from the Pennsylvania Public Utility Commission's official sites, PAPowerSwitch and PAGasSwitch, and instantly shows the lowest fixed-rate electric and gas supplier for your utility. Pennsylvania has energy choice: your market is deregulated, so you can pick who supplies your electricity and gas — often at a lower rate than your utility's default "Price to Compare." But comparing dozens of electric and gas offers by hand is slow. GridScout PA compares energy rates for you in seconds and helps you save on your electric and gas bill. WHAT YOU GET - Your utility's current Price to Compare (PTC) — the benchmark every supplier offer is measured against - The best fixed-rate electricity and gas offer for your utility, with the rate, term length, cancellation fee, and any monthly fee - Filters for Best Value, No Fees, and contract length - A one-tap "Sign up" link that opens the supplier's enrollment page for that exact offer - A home-screen widget with your utility's latest rate COMPARE ELECTRIC RATES FROM PECO Energy, PPL Electric Utilities, Duquesne Light, Met-Ed, Penelec, Penn Power, and West Penn Power. COMPARE NATURAL GAS RATES FROM Columbia Gas of Pennsylvania, PECO Gas, Peoples Natural Gas, UGI, National Fuel Gas, and Philadelphia Gas Works (PGW). WHY FIXED RATES GridScout PA shows fixed-rate plans only. Variable "teaser" rates can look cheap at first, then jump after a month or two — a fixed-rate electricity or gas plan locks in your price for the whole contract, with no surprises. STRAIGHT FROM THE SOURCE Every rate comes from the PUC's own Apples to Apples data — the same numbers you'd see shopping on PAPowerSwitch.com or PAGasSwitch.com — refreshed regularly so you're always comparing current offers. Switching electricity or gas suppliers is free, doesn't interrupt your service, and your utility still delivers the energy and handles billing. GridScout PA just helps you find the cheapest energy supplier and enroll in a couple of taps. Whether you want to lower your electric bill, cut your gas bill, or just see if a better rate is out there, GridScout PA makes energy shopping in Pennsylvania fast and simple. GridScout PA is an independent app. It is not affiliated with, endorsed by, or sponsored by the Pennsylvania Public Utility Commission, any utility, or any energy supplier. Rates are subject to change; always confirm the current price and terms with the supplier before enrolling.
