LinkLock

LinkLock lets you share sensitive text and files as a single encrypted link that expires automatically. You encrypt locally in the browser or mobile app, so the server never sees plaintext. Set rules per link: view-once, time-based expiry, password + recipient verification, and optional device binding. For teams, LinkLock adds audit-friendly metadata (who accessed, when, from what device) without exposing content, plus admin controls for retention and revocation. The realistic angle: it won’t replace enterprise DLP or stop screenshots, but it will dramatically reduce accidental leaks from email attachments, Slack pastes, and “just send it to me” moments. Monetize with a freemium tier for individuals and paid plans for small businesses needing branded domains, access logs, and SSO. Keep it simple: fast sharing, strong crypto, minimal friction.
