Frequently asked questions

No. Files go directly from one of your devices to the other over an encrypted WebRTC connection. RoomDisk has no server that receives or stores them.

No. RoomDisk runs in the browser on iPhone, iPad, Android, Mac, Windows and Linux. You can add a shortcut to your Home Screen or desktop so it opens like an app, offline too.

Both devices need to reach each other: the same Wi-Fi, or one device’s hotspot (no data plan needed). To reach your disk from another network, there’s RoomDisk Anywhere.

Deleted files go to Recently deleted on the spare disk for 30 days. Open Files on the disk, tap Recently deleted, then Put back.

On the disk, open Settings and tap Check now. RoomDisk reads every file back and tells you if anything changed or is missing, so you can replace a failing drive while you still have the originals.

Yes, after the first visit. Turn on one phone’s hotspot, join it with the other device, and pair as usual. Nothing goes over the internet.

The sending device computes a SHA-256 fingerprint of each file; the disk writes the file, reads it back and computes it again. Only matching files are marked “safe to delete”. Receipts list every fingerprint.

Pair again and send the same files: RoomDisk continues each file from where it stopped instead of starting over, and skips files the disk already has.

Yes, free. In the disk’s Settings, set a password: every file is encrypted on that device, the disk asks for the password when it opens, and other devices, nearby or over Anywhere, must enter it before they can see the files. You also get a recovery key, shown once: save it, because it’s the only way in if the password is forgotten.

Yes. WebRTC always encrypts (DTLS). The pairing codes carry each device’s certificate fingerprint and travel face to face (one screen scanned by the other’s camera), so nobody can slip in between.

Yes. Connect to the disk and open Files: folders, thumbnails, full-screen photos, and videos that play straight from the disk.

Any device with a modern browser: an old phone, a tablet, a laptop or a desktop. On a computer in Chrome or Edge it can save to a normal folder; elsewhere it keeps files inside the browser.

No. RoomDisk copies the files you choose when you open it; it’s a manual copy, not a background backup. Phones don’t let websites run in the background.

No. RoomDisk Pro is one payment of $19 ($14.99 at launch) and it’s yours to keep. Only RoomDisk Anywhere is yearly ($29 a year), because it’s the part you use from other networks.

The free plan is the trial: pairing, transfers, checks, resume and duplicate detection are free for everyone, with no time limit and no account.

Purchases are final, because you can use everything that matters in the free version before paying. If something is wrong with your purchase, email us and we’ll make it right.

With the name you chose and your 12-character passcode. There’s no email account or password to manage.

Look for the passcode file you downloaded or the email you sent yourself. Still stuck? Email hello@roomdisk.com with your Stripe receipt.

No. There is no RoomDisk server in the path of your files. They go directly between your devices, encrypted.

Only two short connection messages, encrypted with a key that only your devices have, through public Nostr relays. Files still go directly between your devices.

They’re stored as normal files (or inside the browser), protected by that device’s own lock and encryption. Use a passcode on the disk device.

On the disk, open Devices and forget it. If Anywhere is on, also use “Lock out all devices” in Settings.
