Approval
Keep PC approval on for normal use. If you turn it off for a trusted moment, the start screen calls that out.
Single-use downloads
Send links can expire after the first completed download, or stay reusable until the selected expiration.
Receive upload limits
Receive links can allow up to 16 GB, with warnings above the 2 GB secure default.
Keep useful records without keeping paths forever.
History never stores transfer tokens, URLs, certificates, or file contents.
v0.3.0 adds private history mode and a scrub action for saved local source or destination paths. Metadata can stay available even after repeat shortcuts are disabled.
- Open Settings to turn off remembered transfer locations for future records.
- Use Forget saved locations to remove paths from existing history metadata.
- Open History to search, filter, repeat available setups, or copy a privacy-safe CSV.
Why the browser warning is expected.
FluxDrop uses a local self-signed certificate.
It encrypts the transfer after acceptance, but your browser cannot verify it through a public certificate authority. Confirm that the IP matches the local address shown in FluxDrop before proceeding.
Browser labels differ. Look for an Advanced, Show details, or Continue option, then proceed to the local IP. You normally repeat this only when the selected LAN IP changes or the certificate is regenerated.
If the phone cannot open the QR link.
Confirm the network
Both devices must be on the same private Wi-Fi. Guest networks often isolate devices.
Pause VPN software
A VPN or virtual adapter can make FluxDrop select an address the phone cannot reach.
Choose the LAN adapter
If FluxDrop reports no LAN adapter, connect to private Wi-Fi or Ethernet. Otherwise select the Wi-Fi address that matches your current network.
Copy network details
Open LAN troubleshooting on the live transfer screen and copy the token-safe server, adapter, and last-request details.
Allow FluxDrop on private networks.
- Open Windows Security.
- Select Firewall & network protection.
- Choose Allow an app through firewall.
- Allow FluxDrop for Private networks.
- Leave Public unchecked unless you understand the additional exposure.
Bring the details that make a bug actionable.
Include your Windows version, phone/browser, whether a VPN is active, the selected LAN address, and the exact status shown in FluxDrop. The LAN troubleshooting copy button gathers those details without active transfer tokens. Do not post active transfer URLs or tokens.
