Private by design. Your files, your keys.
Long Drive encrypts files in your browser before they ever leave your device. The platform cannot read your encrypted files — and neither can anyone else without your password.
Start Uploading FreeBrowser-side encryption
Files can be encrypted with AES-256-GCM inside your browser before upload. Plaintext never touches our servers.
Self-custody keys
Your password (or wallet) is the key. Long Drive stores no key material and cannot decrypt your files.
On-chain verification
Every upload returns a transaction ID and file hash that you can verify on the public Arweave network.
01Encryption
Long Drive supports client-side AES-256-GCM encryption. When enabled, your file is encrypted with a key derived from your password before transmission.
The encrypted data is what gets stored on Arweave. Neither Long Drive nor Arweave miners can decrypt it without your password.
02Password & recovery
Your password is never sent to our servers. It protects your private key locally.
If you lose your encryption password, the encrypted file cannot be recovered — by anyone, including us. There is no backdoor. Keep your password and recovery key in a safe place.
03Data storage
Long Drive stores only metadata (file name, size, transaction ID, timestamps) in our database. File content lives on the Arweave network as a permanent data transaction.
Unencrypted file content is streamed through memory only and never written to disk on our servers.
04Verification
After upload, use your transaction ID to verify data on any Arweave gateway. The file hash lets you confirm integrity.
This open architecture means your data does not depend on Long Drive continuing to operate.
Security FAQ
Can Long Drive read my files?
If you encrypt with your own password, no. Encryption happens in your browser and Long Drive holds no key. If you upload without encryption, the file is public on Arweave like any on-chain data.
What happens if Long Drive shuts down?
Your files live on the Arweave network, not on our servers. As long as the Arweave network exists, your data remains retrievable by transaction ID.
Is encryption mandatory?
No, it is optional. For sensitive documents we strongly recommend enabling it. Files stored without encryption are publicly readable on Arweave.
