Works without the internet
All you need is both devices on the same network. Files still move when your router has no internet connection, and when there is no network at all, turning on your phone’s hotspot does the job.
PRODUCTS / SENDRO · FILE TRANSFER
SENDRO
Fast. Private. Lossless.
Move your files
without the internet,
and without losing
a single byte.
Sendro moves files between your computer and your phone over your own Wi-Fi. It never compresses them, never shrinks them and never changes their format. The SHA-256 digest of the file that was sent is compared with the one that arrived, and the transfer counts as verified only when the two are identical.

INTEGRITY
Transfer your files with no loss of quality
Messaging apps compress your photos and videos, drop the quality of your footage and turn your RAW files into JPEGs. Sendro never touches the structure of a file: it reads from disk, moves it across the network and delivers it intact.

If it is not verified, it is not finished
Sendro marks a transfer as verified only when the two digests are identical. If they differ, the file is deleted and you are told about it, so a corrupt copy never quietly stays on your device. And if the connection drops, the transfer picks up where it left off instead of starting over.
FEATURES
The details that speed up daily work
Six-digit pairing
You pair your devices only once. The six digits on the screen never travel over the network: each side derives a proof from them, and only the proofs are compared. A device you have not paired with cannot send you anything.
Watch folders
Put a folder under watch and every new file that lands in it goes to your phone on its own. Offloading a memory card needs no clicks at all.
Works in both directions
You can send from the phone to the computer too. Pick hundreds of files and they all queue up and arrive one by one, and none of them drops out because the other end was busy.
Pair with a QR code
If you would rather not type digits, just scan the QR code shown on the computer. The same works for a TV: scan the code on the screen and the pairing is done.
Nothing starts over
If the Wi-Fi drops or you lock the phone mid-transfer, the file picks up from the exact byte it stopped at. A 12 GB file does not punish you for walking out of range.
GETTING STARTED
Three steps, and then you stop thinking about it
Install and open
Install Sendro on your computer and get the app on your phone. Both being on the same Wi-Fi is enough, and there is no account to create.
Pair once
Your phone finds the computer on the network by itself. Enter the six digits on the screen or scan the QR code, and the app never asks again.
Drag and drop
Just drop the files onto the window. Photos and videos land in your phone’s gallery and everything else in Files, all at full size and all verified.
DEVICES
It runs on every screen in the house
Windows
Sends and receives. It sits quietly in the system tray and watches the folders you choose.
iPhone
Sends and receives. Incoming photos and videos are saved straight to Photos, and you can share files into Sendro from any app.
Android
Sends and receives. Media files land in the gallery and everything else in the Downloads folder.
Android TV
Works as a receiver. It is easy to navigate with the remote, and it opens a film you send in the TV’s own player.
SENDRO LINK
Send to people who do not have the app
If the person next to you does not have Sendro, there is no need to wait for them to install it. Your computer opens a temporary page of its own, and while they are on the same Wi-Fi they open that page in their phone’s browser and download the files you chose. The page is served straight from your computer, so it works without an internet connection.

⇡ Send me a file too
Nobody has to type the address
They just scan the QR code on your computer. The page opens and the files are listed.
◷
You set how long it lasts
Fifteen minutes, thirty minutes, an hour or a day. When the time is up the link closes by itself, and you can close it earlier with a single tap.
▤
Only the files you picked are visible
The other side cannot browse your computer. There is no folder listing at all, only the files you added to that session.
⚿
The address cannot be guessed
The address carries a randomly generated 32-character key. Unless you share it, nobody can find the session.
⇅
They can send you files too
Turn on guest uploads and they can send files back from the same page. Whatever arrives is listed on your side as coming from a guest.
◌
Nothing is left behind when it closes
The session lives only in memory. Close the app or let the time run out and the address stops working for good, and the same address is never reused.
NOTES
Text that deletes itself after a day
Sometimes what the other screen needs is not a file but a single line of text: a Wi-Fi password, a link, a tracking number. Whatever you send lands in the Notes tab on the other device. It stays there for 24 hours so you can read it again, then deletes itself. Your computer never writes it to disk at all.
⇅
It works both ways
Send text from the computer to the phone, or from the phone to the computer. Same box, same rules.
◷
One day, then gone
Every note carries its own expiry. Anything past it is cleared when you open the app, and swept again every minute while it is open. There is no way to extend one.
⧉
One tap to copy
Tap Copy and the text is on the clipboard, ready to paste straight into Wi-Fi settings or a browser.
▣
The computer keeps nothing
On the computer the text lives in memory only and is gone when you close its card. It is never written to disk and never appears in transfer history.
◍
Never in a notification
The notification only tells you who wrote to you. The text itself never appears in the banner, so it cannot be read off a locked screen.

QUESTIONS
Frequently asked questions
Is there really no loss of quality?
No. Sendro never looks inside a file; it carries the bytes exactly as they are. The SHA-256 digests of the file sent and the file received are compared, and if they differ the transfer counts as failed. A 300 MB video is still 300 MB at the other end.
Does the other person need the app as well?
No. With Sendro Link your computer opens a temporary page, and while they are on the same Wi-Fi they open it in a browser and download the files. They install nothing at all.
How many devices can I pair?
As many as you like. You can pair your computer with your phone, your tablet and your TV separately, and send files to all of them at the same time.
My router has no internet. Will it still work?
Yes. All Sendro needs is for both devices to be on the same local network. A router with no internet connection, or your phone’s hotspot, is more than enough.
How many files can I send at once?
There is no limit. Pick hundreds of files and they all queue up and arrive in turn. If a transfer is interrupted, the file resumes from where it stopped instead of starting over.
Does it cost anything?
No, Sendro is free. There is no subscription, no file size cap, no daily quota and nothing to buy inside the app.
