How is my data secured?
Every upload receives a fresh 128-bit identifier. Guessing it is like searching for a single pixel across every screen on earth, so your content stays private by design.
Frequently Asked Questions
Where does the file live?
It lands in the LOCKR edge region you select (us-central1, us-east4, us-west1, europe-west1, europe-west4, asia-southeast1, asia-northeast1, australia-southeast1), stored inside a private bucket tied to that identifier. No key, no access.
Why offer an optional download key?
Share a passphrase when you want an extra handshake. We hash it alongside the file so only someone with the same phrase can unlock the download—skip it if brute security already fits.
How do I change themes?
Tap the sun or moon in the header. We remember your preference with a lightweight cookie so the interface greets you with the same lighting next visit.
