Internxt encrypts files on your device before upload, on free and paid accounts, and its app code is public on GitHub. Our October tests timed a batch of 1,000 phone photos and videos. Internxt uploaded it in 13 minutes 9 seconds, near the maximum our connection allows, and every file arrived. A short video clip and a song also played in the browser.
The catches are in the plan details. Version history covers only PDF, Word, Excel, and CSV files, and only on the two largest plans. Under Internxt’s terms, a lifetime account can be closed after a year of inactivity.
Internxt
Every Internxt plan encrypts files on the device, the apps are open source and audited, and our 1,000-photo upload used most of our connection. Version history covers only office documents on the Premium and Ultimate plans, share links can't expire, and lifetime accounts require activity at least once a year.
Pros
- Client-side encryption on every plan, including free
- Open-source apps with independent audits
- Fast uploads of large photo folders
- Short videos and songs play in the browser
- One-time lifetime plans
- Trash folder on every plan
Cons
- Version history limited to office documents
- No expiry dates for share links
- Lifetime accounts closed after long inactivity
- Small free plan
- Euro pricing for US buyers
- High CPU use during large uploads
Desktop and Phone Apps
Internxt supports Windows, macOS, Linux, iPhone, Android, and web browsers. On Windows 11, the app adds Internxt Drive to File Explorer. Files stay online until opened, and the right-click menu can keep any file offline or copy a share link. Paid plans add backups of chosen PC folders.
On paid plans, the phone apps back up the whole gallery automatically. Free accounts upload photos from the camera roll by hand.
Transfer Speeds
Our October tests used a Windows PC in Europe, where Speedtest measured 187.95 Mbps down and 19.69 Mbps up. The many-files test used a 1.67 GB folder of 1,000 phone photos and short videos.
| Upload | Download | |
| 500 MB music and video archive | 3:34 | 0:24 |
| Single 2 GB file | 15:28 | 1:51 |
| Folder of 1,000 photos and videos | 13:09 | 1:55 |
The folder upload took 93% of our upload capacity, about the same share as the single 2 GB file. Many small files didn’t slow Internxt down. CPU use was the downside: it peaked at 84% during the folder upload, a heavy load for a background sync.
Only pCloud, Dropbox, and Google Drive uploaded the 2 GB file faster. Internxt’s 500 MB download tied the quickest we timed, at 24 seconds. The fastest cloud storage page lists every service’s times, and Internxt vs pCloud compares two lifetime services directly.
File Previews and Playback
In the web app, PDF, Word, plain text, and image files opened without a download. A short MP4 clip and an MP3 song played in the browser. A larger MP4 loaded for a while, then showed no preview and offered a download instead. The phone app played the same clip but opened the MP3 and text file in other apps.
Documents open read-only, so editing still requires a desktop app. Our cloud storage for photos ranking looks at services built for photo and video libraries.
Version History and Deleted Files
Version history worked when we tested it on a paid account. Only the Premium and Ultimate plans include it, and photos and videos have no version history on any plan. Deleted files stay in the trash longer on bigger plans:
- Free: 2-day trash, no version history
- Essential: 7-day trash, no version history
- Premium: 15-day trash and 15 days of version history for documents up to 10 MB
- Ultimate: 30-day trash and 30 days of version history for documents up to 20 MB
Files deleted in the Windows app also go to the trash, and we restored one from there. On the free and Essential plans, a mistake has to be noticed within days.
Sharing Files and Folders
Free accounts can share any file or folder through a public link. Paid plans add password-protected links and restricted sharing with invited Internxt users.
Links can’t be set to expire, so a public link stays active until you stop sharing it. For links that expire on a set date, see our NordLocker review.
Encryption, Audits, and Data Location
Files are encrypted with AES-256 before they leave your device, and the keys are protected by an extra layer of post-quantum encryption. Internxt doesn’t store your password. Losing it means losing your files unless you saved the backup key. Two-factor authentication is available. The apps are open source, and Securitum has audited them twice.
The first found a high-risk flaw in Internxt Send, the company’s file transfer tool, which was fixed. Internxt says the second found no critical issues. The company, Internxt Universal Technologies, operates from Valencia under Spanish law and the GDPR. Its privacy policy says Internxt has servers in several countries, including some outside the EU. File contents stay encrypted either way.

It also sells yearly subscriptions. Every plan comes with a 30-day refund window. Our cheapest cloud storage list covers lower yearly prices, and the free cloud storage ranking has larger free plans.
What Lifetime Means at Internxt
Internxt’s terms set the end of a lifetime plan at the account holder’s 99th birthday. An account with no login, upload, or download for 12 months counts as inactive. Internxt then sends an email, and without a reply within 30 days, it can delete the account and its files with no refund.
A fair-use policy covers lifetime plans. Internxt can throttle, suspend, or close accounts whose storage, bandwidth, or file count it considers excessive. The terms also make users responsible for their own backups. Signing in once a year keeps a lifetime account active.
Conclusion
Internxt turns encrypted storage into a one-time purchase. The Premium plan covers 3 TB for €435, every plan encrypts files before upload, and large photo folders uploaded at close to full speed. Version history protects only office documents on the two top plans, share links never expire, and a lifetime account requires some activity every year. Internxt is a good fit for private document and photo archives paid for once.
pCloud saves earlier versions of every file type for 30 days on paid plans, adds a music player, and also sells lifetime plans. Internxt and pCloud are compared with other services in our best cloud storage rankings.
