A little more clarity.
What happens to your files, and what not to assume.
Cloud links expire. Storage cleanup follows separately.
Experimental peer-to-peer sharing needs both tabs to stay open.
Where does a cloud upload go?
Into private object storage, through the service. Share the resulting link only with people you trust: anyone holding a valid link can download the file.
Does expiry delete the file immediately?
No. Expiry prevents new downloads through the link. A separate cron cleanup removes stored files afterward. Physical deletion can lag, especially if cleanup is delayed or fails. Previously downloaded copies cannot be recalled.
What size and expiry can I choose?
Use the cloud limit and expiry choices shown in the uploader. The default cloud allowance is 5 GB and default expiry is 24 hours, measured from upload initiation. Encrypted cloud has a separate 32 MiB envelope cap including filename and encryption overhead, and must also fit the cloud limit. P2P allows files up to 32 MiB. These are data caps, not total browser memory limits.
Are cloud uploads end-to-end encrypted?
Only when you enable optional browser encryption before uploading. AES-256-GCM protects the file and original filename in the browser; standard cloud uploads remain readable by the operator. The recipient needs the complete link including #key=. The key fragment is not sent in HTTP requests, but anyone with the complete link can decrypt it. Trust your browser and the code served by the operator.
Can I recover a lost encryption key?
The service cannot recover it. Ask the sender for the complete link if they still have it, otherwise ask them to encrypt and upload the original again. A link without its #key= fragment cannot decrypt the file.
Why am I being asked for an upload token?
This deployment may require Bearer-token authentication for cloud uploads. Enter a token obtained privately from the operator; the UI keeps it in page memory, not persistent storage. This is access control, not CAPTCHA, and it does not make share links recipient-specific.
How does peer-to-peer sharing work?
Choose P2P mode and exchange an offer and answer manually through a trusted separate channel. This experimental WebRTC mode is local-network only, with no STUN/TURN servers, public signaling service, or cloud fallback. Files travel over a DTLS-encrypted data channel. Network isolation or browser restrictions can prevent connections even on the same network; encryption does not verify the other person’s identity.
Can I close the tab during a peer-to-peer transfer?
Keep both tabs open and both devices connected until the transfer finishes. A sleeping device, closed tab, or interrupted connection can stop it. Do not assume a background transfer or automatic resume is available.
Is peer-to-peer anonymous?
No anonymity guarantee is provided. WebRTC peers may learn network information, including IP addresses. Only connect with someone you trust.
Why does the theme change with my device?
System is the default and follows your operating system’s light or dark preference, including changes while the page is open. Choose Light or Dark for a fixed appearance. Your choice is saved in this browser.
