Unidy vs OneDrive
OneDrive is bulk storage for all your files, built to work with Word, Excel and the rest of Microsoft 365. Unidy is for your most important personal documents, like your passport or your lease, shared with a PIN and an end date, and for your contacts and your digital business card.
| Feature | Unidy | OneDrive |
|---|---|---|
| Price and free storage | 1 GB free for your documents. More space: $1 per GB a year. It costs more than bulk storage because Unidy reads and encrypts each document, and makes a new protected copy every time you share it | 5 GB free with a Microsoft account. 1 TB with Microsoft 365 Personal: $9.99 a month, or $99.99 a year |
| Encryption when stored (at rest) and sent (in transit) | AES-256 at rest. TLS 1.3 with a hybrid post-quantum key exchange | A unique AES-256 key per file at rest. TLS in transit, version not stated |
| End-to-end encryption | Not end-to-end. One key per person, kept apart from your information. No master key | Not described as end-to-end. Microsoft holds the keys. Personal Vault adds a second sign-in step and locks itself |
| A copy for each recipient, with their name on it | A fresh copy for each person, company or government office, never your stored file, with their name, the purpose of the share and the date watermarked by default | People you share with open the same file. No watermark |
| PIN or password on a shared file | A 6-digit PIN, on by default. If you want, also a password on the PDF copy, which it still asks for once downloaded | Link password, Microsoft 365 subscribers |
| End date and limit on openings for a shared file | Every shared copy stops opening after 7 days at most, and can be limited to 1, 3, 5 or 10 openings | Link expiry date, Microsoft 365 subscribers. No limit on views |
| See who opened a shared file | Every opening of a shared copy, with time, approximate place and device, and refused attempts | Not found on their site |
| Share only some pages or some details | Chosen pages of a document, or chosen details such as name and photo | Not found on their site |
| Reads expiry dates and reminds you | Reads a document’s expiry date and reminds you months before, free | Not found on their site. Personal Vault can scan documents in the mobile app |
| Contacts that update themselves, and a digital business card | People you’re connected with on Unidy get your new details. A personal digital business card and up to 5 professional ones, free | Not found on their site |
| Selling your data, or using it for ads | Unidy never sells your personal information and builds no ad profiles | Microsoft's Services Agreement says your documents, photos and other files are not used to target ads |

Where OneDrive is the better choice
- Working on Word, Excel and PowerPoint files, alone or together, with Microsoft 365.
- Large amounts of space: 1 TB with Microsoft 365 Personal, and a 2 TB shared pool with Family.
- Keeping all your files in sync across your devices.
- OneDrive’s Personal Vault, an extra locked area for your most sensitive files.
Where Unidy is different
- Each time you share a document, Unidy makes a new copy just for that recipient, a person, a company or a government office, with their name and the date written across it.
- Every document you share has a PIN by default, an end date of 7 days at most and, if you like, a limit on openings, all free.
- You see each time someone opens a document you shared: when, roughly where, and on what device.
- You can share chosen pages, or only some details, such as a name and photo instead of a whole passport.
- Unidy reads the expiry date of a passport or driver’s license and reminds you months before it runs out.
- Change a detail, like your phone number, and your digital business card and the people connected with you on Unidy get the new one.
Using both
Keep your files and Office work in OneDrive. Keep your important documents, such as your passport and ID card, in Unidy, and share them from there.
Unidy accepts PDF, photos (including iPhone HEIC), Word and Excel files, so you can add the documents you already have.
