Frequently Asked Questions
Can I send files between my phone and computer?
Yes. Create a share code on one device and enter it on the other device.
How long are files stored?
The interface offers 10 minutes, 1 hour, 6 hours, and 24 hours. Your backend must enforce expiration.
Which file types can be shared?
The frontend accepts general files, but your production backend should allow only the safe file types you explicitly configure.
Does this HTML work without a backend?
Small-file demo sharing can work in the same browser using local storage, but true cross-device transfer requires WordPress REST endpoints and temporary server storage.
