Privacy
Last updated 26 October 2026
PDF Duo collects no data. There is no account, no analytics, no advertising and no tracking, and the app makes no network requests of its own.
Your documents
PDF Duo opens your PDFs where they are, in Files, iCloud Drive or any folder you connect. Nothing is uploaded: Alano runs no server or cloud service for PDF Duo, and we never see your documents.
While you edit, unsaved changes are kept in a small journal on your iPhone so they can come back after a crash. It never leaves the device.
Your signatures
Signatures and initials you save are stored in the iPhone's Keychain for this device only. They are not synced to iCloud and never uploaded.
What we collect
Nothing. PDF Duo contains no analytics, crash-reporting or advertising SDK. In App Store terms: Data Not Collected.
Apple may give developers aggregate App Store figures (downloads, and crash reports from people who chose to share them with developers). These come from Apple, under Apple's privacy policy.
Links
The only web link in the app opens alano.ai, and only when you tap it.
This website
This site sets no cookies and runs no analytics. Our host, Vercel, keeps standard server logs to run and protect the service.
Children
PDF Duo collects no data from anyone, including children.
