Storage
uFiles gives you nested folders, drag-and-drop upload, image previews, filters and per-file sharing with read/write/admin permissions — over an encrypted Personal Storage layer that syncs across devices.

Alternative
UltimaOS as a Google Drive alternative
Google Drive can read your files to power its products. UltimaOS cannot read them at all.
Looking for an alternative to Google Drive, or a Google Drive substitute that cannot read what you store? Google Drive stores your files — and your Docs and Sheets — on Google's US servers in a form Google can read. UltimaOS gives you the same everyday storage plus documents and spreadsheets, through uFiles, uDocs and uSheets, inside a web operating system that encrypts everything end-to-end on your device and runs entirely in the EU.
01
Overview
What replaces Google Drive inside UltimaOS.
02
Documents
uDocs is a rich-text word processor with real-time multiplayer editing, presence cursors, tables, images and a side AI assistant — covering what you use Google Docs for.
03
Spreadsheets
uSheets is a full spreadsheet engine with multi-sheet workbooks, formulas, real-time co-editing and .xlsx import/export that preserves validation rules — covering Google Sheets.
02
Details
Where the real difference is.
Both give you storage and office apps. The difference is whether the provider can read your content and whose law governs it.
01
Who can read your data
Google Drive content is stored on Google's servers in a form Google can read, and is reachable by US authorities under the CLOUD Act even in EU regions. UltimaOS encrypts everything end-to-end on your device with no server-side key, so the operating system cannot read your files or documents.
02
Where your data lives
UltimaOS runs entirely on EU infrastructure under EU jurisdiction — no transatlantic transfer, GDPR-aligned by architecture. With Google, jurisdiction ultimately follows the vendor regardless of the region you pick.
03
The business model
Google's core business is built around data. UltimaOS has no advertising model and cannot profile what it cannot read — there is neither the incentive nor the technical ability to mine your files.
04
One encrypted environment
Storage, documents and spreadsheets share one encrypted file system and one identity, rather than being separate products joined by a login.
03
Key points
What you keep, what you gain.
-
01
You keep storage, docs and sheets
The everyday trio — files, documents, spreadsheets — is all present, with real-time collaboration on docs and sheets.
-
02
You gain end-to-end encryption
Content is encrypted to your key before it leaves the device; the server holds ciphertext it cannot read.
-
03
You gain EU sovereignty
EU hosting, EU jurisdiction and no data mining are the default state of the operating system, not a premium setting.

Frequently asked
UltimaOS as a Google Drive alternative — common questions
Is UltimaOS a private Google Drive alternative?
Short answer
Yes. uFiles replaces Drive storage while uDocs and uSheets replace Docs and Sheets — all end-to-end encrypted and EU-hosted, so the provider cannot read your content the way Google can.
Can Google read my files in Google Drive?
Short answer
Google stores Drive content in a form it can read, and it is reachable by US authorities under the CLOUD Act even in EU regions. UltimaOS encrypts on your device with no server-side key, so it cannot read your files.
Do the documents and spreadsheets collaborate in real time?
Short answer
Yes. uDocs and uSheets support real-time multiplayer editing with presence cursors and a live peer count.
Can I import my existing spreadsheets?
Short answer
Yes. uSheets supports .xlsx import and export, preserving validation rules, so existing spreadsheets move over.
Where is my data hosted?
Short answer
On EU infrastructure under EU jurisdiction, with no transatlantic transfer. GDPR alignment is architectural.
