Your Excel data, your rules
By default, everything stays local — your workbooks never leave your device. And when you need more convenience, Airrange hosts your data encrypted in the EU. Either way, you stay in control.
- Work with local and on-premises files — without uploading them
- EU-hosted in Frankfurt — GDPR-compliant by design
- Your IP is hidden to the end users - no one gets full access to your formulas and data
- Airrange does not store any credentials
Your Excel files remain inaccessible to your users
When you share an app, Airrange bundles only the formulas and data that app actually needs into an encrypted Calculation Package — never your full workbook. Airrange holds no access rights to your files, and on Enterprise plans you can keep these packages entirely on your own infrastructure.

Apps can be locked to specific email addresses and tenants
Lock the app access to specific domains or email addresses. You can also define the duration of the invitations and set additional passwords. Inside the apps you can even define specific functionality for different users.
The app building process
App building happens entirely in the user's browser — Excel files are never uploaded to Airrange servers. Technically, the browser receives a file handle to the local file, so only the browser can access the workbook contents. Airrange never sees the data. On our servers we only store metadata about the app — for example, that there is a combobox, its layout, and that it is linked to cell C3. We do not know what's inside C3.
When an app is shared, an encrypted Calculation Package (a JSON file) is created that contains only the formulas and data the app needs — never the whole workbook. On Free and Pro plans this encrypted package is stored on AWS in Frankfurt (EU). On Enterprise plans you can store it on your own platform, so your workbook data never lives on Airrange's servers. Your data stays under your control at all times: local, encrypted, and secure.

You choose where your data lives
Airrange lets you pick the storage model that fits your security requirements — and you stay in control either way. Local and on-premises files are never uploaded; Airrange only ever holds metadata about the app. Microsoft 365 workbooks keep their app definitions inside the Excel file itself, in your own tenant. And with Hosted Files, Airrange stores your workbook encrypted on AWS in Frankfurt (EU) — the convenient option, still fully GDPR-compliant. Same product, your decision.
Built on certified infrastructure
Whichever storage model you choose, the platform that runs Airrange is built on infrastructure with industry-leading security certifications. These attestations are held by our infrastructure providers and independently audited every year.

Passwordless, phishing-resistant sign-in
Airrange has no password to steal. You sign in either with a one-time email passcode or with your Google account — there is no Airrange password to create, reuse, or leak. Authentication is handled by Hanko, a FIDO2-certified, EU-based identity platform, so logins stay resistant to phishing and credential theft.

Need complete data sovereignty?
On Enterprise plans, you bring your own storage: the encrypted Calculation Packages live on infrastructure you control — Azure, AWS, your own server, wherever you decide. Apps still run in Airrange, but your workbook data never sits on Airrange's servers; only metadata does. You decide who can reach your storage.
