Locker Drop is the private way to send big files. Your file is encrypted in the browser before it uploads, so we never get the key and literally can't read it. True zero-knowledge, not a promise. Share one link. The file self-destructs on a timer, or the instant it's opened. No recipient account, no app, any browser. Pay per send, no subscription. Documents to multi-terabyte transfers. For anyone sending what shouldn't sit on a server forever: contracts, medical records, source code, exports.
