About

One file. One person. Gone when it’s done.


OTDrop is the quick, sealed handoff for the rest of us. Drop in a file, type a recipient, write a short note. Your browser seals the file before it leaves your device, we hand it off through a one-time pickup link verified against the recipient’s phone, and then it is gone — after one download, or after seven days, whichever comes first.

Most file-sharing tools were built for something other than the everyday “I just need to send this one thing to this one person” case. Email attachments leak into long-lived archives. Generic cloud-share links live forever and travel further than you meant. Dedicated managed-delivery platforms are priced and shaped for regulated workflows. OTDrop is none of those. It is a free general-purpose utility, honest about what it protects and what it does not, and useful every day.

When to use OTDrop


  • You are sending one file to one person.
  • You want the handoff sealed in your browser before it leaves your device.
  • You want the recipient to prove possession of a phone you already know.
  • You want the file gone after it has been picked up.
  • You don’t want the recipient to have to make an account.

When to use something else


If your workflow needs retention holds, auditable chain-of-custody, identity assurance beyond a phone, data-residency contracts, or formal compliance attestations, use a managed secure-delivery platform designed for that job. OTDrop is intentionally the simple tool. See the security page for an honest description of where its limits are.

Who builds it


OTDrop is a product of NuSecuritas, LLC, a small team based in Michigan that builds practical privacy and security tools for people who don’t consider themselves “technical.” We also operate work in the managed secure-delivery space; if OTDrop is not the right fit for what you are doing, we can point you at something that is.
