Vlemon LLP · Password Manager

One encrypted vault. Two ways to run it.

Monolith stores your credentials, notes, and TOTP secrets in an encrypted, on-device vault — no account required. Pick Monolith Vault for a fully offline, one-time-paid vault, or Monolith Spark for the same vault, free, supported by ads.

See Vault & Spark Privacy & Terms

Same vault engine, two products

Both apps encrypt your credentials on your device. They differ in price, ads, and network access — not in how your data is protected.

One-time paid · Offline

Monolith Vault

Air-gapped credential vault. No account, no cloud sync, no ads, no analytics — the release build is designed to run without network access at all.

Vault privacy & terms → Free · Ad-supported

Monolith Spark

The same on-device vault, free to use. Spark shows banner and interstitial ads via Google Mobile Ads and needs network access for that — your vault contents are never sent to Google or to us.

Monolith is completing app-store review. Store links go live here once Vault and Spark are published — contact us if you'd like to know when.

Vault vs. Spark

Choose Vault if you want zero ads and zero network access. Choose Spark if you want to try Monolith for free — you can move your vault to Vault later.
