Private office suite · runs in your browser
Edit documents, spreadsheets, slides and PDFs without uploading them
Vault Studio Pro opens and saves .docx, .xlsx, .pptx, PDF and image files entirely inside your browser. Your files are processed on your device. There's no account to create and nothing to install.
Free to use. Pro features unlocked for your first 7 days. No sign-up.
Privacy you can check, not just a promise
1. The work happens in your browser
The editors, the PDF engine, text recognition and encryption all run as code inside the page. When you open a file, it is read from your disk into the tab. It isn't sent to a server to be converted.
2. Your browser enforces it
Every page ships a Content-Security-Policy with connect-src 'self'. That tells your browser to block the page from connecting to any other website, even if a bug or a booby-trapped file tried to. Fonts, OCR data and the PDF engine are served from our own domain for the same reason.
3. You can see the requests
The built-in Privacy Audit shows the browser's own log of every request the page has made, and anything the policy blocked. It can't see requests from background workers, so it also shows you how to check in your browser's developer tools.
One exception: dictation uses your browser's speech service, which may send audio to Google or Apple. The app asks first. Read the full security details.
Five tools in one tab
Move work between them: send PDF tables to Sheets, scanned text to Docs, or an edited image into a slide.
.docx documents
Docs
Write and edit documents with comments, suggestions, tables and equations. Save as .docx.
.xlsx spreadsheets
Sheets
Formulas, charts, pivot tables and conditional formatting. Opens .xlsx, .xls and .csv.
.pptx presentations
Slides
Build decks, present full screen with notes and a timer, and export .pptx.
PDF editor
PDF
Annotate, sign, fill forms, OCR scans, merge, split and compress, with real redaction.
Images
Image Studio
Crop, adjust, black out details, cut out backgrounds and convert to WebP, JPEG or PNG.
Built in
Redaction and the File Safe
Redact PDFs so hidden text is really removed, and lock any file in an AES-256 encrypted .vault. Both free.
Keep what you paid for
With Pro Annual or the Founders plan, every Pro feature released during your paid year is yours to keep, even if you don't renew. Renewing only gets you the features released after that. There's no cloud account to lose access to: your license key is checked on your device.

Frequently asked questions
Are my files uploaded anywhere?
No. Opening, editing and saving happen inside your browser tab, on your device. The page also tells your browser, through its Content-Security-Policy, to refuse connections to any other website. The only requests the app makes to our own server are for the app's files and, if you buy a license, to claim or renew your license key.
Do I need an account?
No. There are no accounts, no sign-in and no email required to use the app. If you buy Pro you get a license key, and the app checks its signature on your device. Subscription keys are renewed with one short request to our server near the end of each billing period.
Where are my documents stored?
In your browser's own storage (IndexedDB and localStorage) on the device you are using. That storage is not encrypted, and clearing your browser's site data deletes it, so save important files to your computer. For an encrypted copy, export a password-protected .vault file.
Can it open files made in Microsoft Word, Excel and PowerPoint?
Yes, it opens .docx, .xlsx, .xls, .csv and .pptx files and saves .docx, .xlsx and .pptx files that those programs can open. Complex files can be simplified on import: not every Excel function is supported, and presentation gradients, charts and SmartArt are simplified. Each tool page lists its limits.
What is free and what needs Pro?
Every editor is free, along with PDF redaction, the File Safe encryption, OCR on the first page of a PDF, and PDF Tools jobs of up to 3 files. Pro adds OCR on every page, larger PDF Tools batches and revision history. Every Pro feature is unlocked for the first 7 days after you first open the app.
What happens if I stop paying for Pro Annual?
You keep every Pro feature that was released during the year you paid for, forever. Only Pro features released after your paid year ends need a renewal. The changelog records the date each Pro feature was released.
Does dictation stay on my device?
No. Dictation uses your browser's speech recognition service, which may send your audio to Google (in Chrome) or Apple (in Safari). The app asks before turning it on. Every other feature processes your files on your device.
Is this made by Microsoft or Adobe?
No. Vault Studio Pro is an independent product. It works with the standard .docx, .xlsx, .pptx and PDF file formats but is not affiliated with or endorsed by Microsoft or Adobe.
