How can we help?

Windows, Linux, iPhone, iPad and Android. A Mac version is in development for the Mac App Store and has no release date yet.

On Windows, get it from the Microsoft Store or download the installer. Both install the same app. On Linux, download the AppImage for x86_64 or ARM64 (aarch64) and run chmod +x on the file before you open it. iPhone and iPad use the App Store, and Android uses Google Play.

You need iOS 16 or later, Android 7.0 or later, Windows 10 version 1809 or later (64-bit), or Linux with glibc 2.35 or newer (Ubuntu 22.04, Debian 12, Fedora 36 or later).

Install OpenDrop on your computer and open it. It shows a QR code. Open the OpenDrop app on your phone and scan that code. Free needs no account.

On Free, each phone pairs with one computer, and scanning a different computer's code moves the phone to that computer. With Pro, sign in to the same OpenDrop account on each device and they connect automatically, with no QR code.

The QR code holds a private pairing key. Anyone who scans it can pair with your computer, so do not share screenshots of it.

Make sure OpenDrop is open on the computer and both devices run the latest version, because outdated versions are asked to update. On Free, scan the QR code on the computer again: the phone connects to the computer whose code it scanned last. If the devices are on different networks, both need an internet connection. You do not need to forward any ports.

On the same Wi-Fi, allow OpenDrop through the computer's firewall for private networks. It listens on port 8000 by default. If it still fails, check System status, then send us a ticket.

The Windows installer and the Linux AppImage check for updates when they start and install a new version in one click, verified with SHA-256. The Microsoft Store version tells you when an update is out and opens its Store page. On iPhone, iPad and Android, update through the App Store or Google Play.

OpenDrop picks the route for you. Free tries a direct peer-to-peer link first, then OpenDrop's shared relay. Pro starts on the faster Pro relay and keeps peer-to-peer as a backup. There is nothing extra to install and no port to forward.

Free remote transfers are speed-limited, move in 5 MB pieces and share a weekly fair-use allowance on the free relay. Pro streams the whole file at full speed with no weekly limit. On both plans, a dropped connection picks up where it left off.

No. Neither plan has a per-file size cap. On the same Wi-Fi, files stream directly at full speed on both plans, with no chunking. Away from your Wi-Fi, Free is speed-limited and Pro runs at full speed.

Remote uploads from your phone keep going in the background on iPhone, and for a while on Android. Transfers over Wi-Fi or peer-to-peer, and all downloads to your phone, need the OpenDrop app open.

Free sends files between each phone and the computer it is paired with: at full speed on the same Wi-Fi and speed-limited over the internet, with no account and no file size cap.

Pro adds phone to phone (iPhone and Android) and computer to computer transfers, Bluetooth between two phones when there is no Wi-Fi, automatic connection for every device signed in to your account, the faster Pro relay with no weekly limit, subfolder browsing, new folders and shared folders, and photo, video and RAW conversion, which runs on a computer.

Subscribe inside the OpenDrop app. iPhone and iPad use the App Store, and Android uses Google Play. On Windows or Linux, sign in in the desktop app and choose Upgrade to Pro. You sign in with Google, Apple, Microsoft or email. Pro is tied to your OpenDrop account, so one subscription covers all your devices.

Cancel where you subscribed. On iPhone and iPad, open Settings, tap your name, then Subscriptions. On Android, open Google Play, tap your profile icon, then Payments and subscriptions, then Subscriptions. For a subscription bought in the desktop app, use the Stripe customer portal linked from your purchase email. You keep Pro until the end of the period you paid for.

Refunds go through the store that took your payment: Apple for the App Store, Google for Google Play, and the contact email on your Stripe receipt for desktop purchases. In the EU or UK you may also have a right of withdrawal. Use the withdrawal form or email support@nfdgames.com.

Yes. File contents are encrypted with ChaCha20-Poly1305 on your device before they leave it, with a key derived (HKDF-SHA256) from a secret your paired devices share. Encryption is mandatory over Wi-Fi, peer-to-peer, the relay and Bluetooth between Pro phones, and OpenDrop refuses to send or accept unencrypted file data. Requests between your devices are signed with HMAC-SHA256.

Relay servers carry file contents only in encrypted form. They can see transfer details such as file names, folder names, file sizes and device names, which they need to route transfers. On Free, the key is made on your computer and shared through the QR code. With Pro, OpenDrop's account service also stores it so your signed-in devices can connect.

Free needs no account. The app sends basic usage statistics to our own server: a random install ID, the app version and platform, active-user counts and error counts, with email addresses hashed. The statistics include nothing about your files, and there are no ads. Turn them off in Settings with Disable basic analytics. The Privacy Policy has the full details.

In the OpenDrop app on your phone or computer, open Settings, then Account, then Delete Account. You can also email support@nfdgames.com from the address on your account with the subject Delete My Account. Files on your devices are not affected.
