Summary

LOCK.PUB and SecureMint share the same fundamental philosophy: zero-knowledge, no-signup, browser-only encrypted file sharing aimed at the Japanese market. Where LOCK.PUB focuses narrowly on ad-free encrypted file delivery, SecureMint is a broader security toolkit — file encryption, secure sharing, metadata removal, password generation, secure memos (burn-after-reading), breach checks, and an IPA-based self-assessment are all free and in one place. SecureMint also offers a paid Pro plan ($7.99/mo) with per-link download tracking, SecureChannel messaging, and file request links, plus a full Japanese legal disclosure page (特定商取引法) that business customers require. If you only need to send one encrypted file now, either tool works well. If you want to consolidate your SMB security posture into a single bilingual browser tool with business-grade features and legal paperwork, SecureMint goes further.

FAQ

Are LOCK.PUB and SecureMint both really zero-knowledge?
Yes, both advertise and implement zero-knowledge E2E encryption in the browser with keys that never reach the server. Both are legitimate implementations of the no-signup, no-server-side-plaintext model.
What does SecureMint offer that LOCK.PUB doesn't?
Self-decrypting HTML (recipient needs no SecureMint at all), metadata removal, a password generator, a breach check tool, secure memos with burn-after-reading, file request (inbound) links, download tracking on Pro, an IPA-based 25-question security self-assessment, full Japanese legal disclosure (特定商取引法) for B2B customers, and an English UI for cross-border use. LOCK.PUB focuses on file sending specifically.
Which is better for Japanese SMBs specifically?
Both are well-suited to the Japanese SMB market. If your need is narrow — just 'send an encrypted file without signing up' — LOCK.PUB is excellent. If you also want metadata removal, password generation, self-assessment, burn-after-reading memos, and formal legal disclosure for B2B contracts, SecureMint covers more surface area in a single tool.
Does using SecureMint Pro lock me in?
No. Pro is $7.99/month (or $79.99/year, ~17% off) with no long-term commitment. The free tier remains fully usable without Pro — you can go back to the free model at any time. The zero-knowledge architecture means your past files are not tied to your account in any meaningful way.
