Privacy Policy
Effective date: March 3, 2026
In short: SignPaper processes your documents and signatures on your device. No accounts. No personal data leaves your device. We use a privacy-first, anonymous analytics service (TelemetryDeck) to measure aggregate product usage — no IDFA, no personal identifiers, no cross-app tracking.
What SignPaper Does
SignPaper is a document signing application for iOS. It lets you import PDFs and images, add signatures, text, dates, and stamps, and export or share signed documents — all on your device.
Data We Collect
SignPaper does not collect, transmit, or store any personal data or document content on our servers.
- No advertising frameworks
- No user accounts or registration
- No tracking across other apps or websites
- No advertising identifiers (IDFA) collected
Network requests are limited to:
- Apple StoreKit — for in-app purchases and subscriptions.
- Apple CloudKit — only if you enable iCloud Sync, to store your documents in your private iCloud container.
- TelemetryDeck — anonymous, aggregate usage analytics (see below).
Anonymous Usage Analytics (TelemetryDeck)
SignPaper uses TelemetryDeck, a privacy-focused, GDPR-compliant analytics service hosted in the EU, to understand how the app is used in aggregate and to improve it.
What is sent: anonymous event signals such as when a document is imported, a signature is created, the paywall is shown, a purchase is completed, and which screens are viewed. Each signal includes basic non-identifying context (app version, iOS version, device class, country derived from IP and then discarded).
What is NOT sent: your name, email, Apple ID, IDFA, precise location, document content, signature images, file names, or any other personally identifying information. TelemetryDeck does not store IP addresses and uses a one-way hashed installation identifier so signals cannot be tied back to you.
Document Processing
All document signing and processing happens entirely on your device. Documents never leave your device unless you explicitly share them using the system share sheet.
iCloud Sync
If you enable iCloud Sync, your documents and signatures are stored in your private iCloud container managed by Apple. This data is only accessible to you through your Apple ID. We do not have access to your iCloud data.
Signatures
Your signature data — drawn, typed, or extracted from photos — is stored locally on your device and, if iCloud Sync is enabled, in your private iCloud container. We never transmit your signature data to any third party.
Camera and Photos
When you use the camera to scan documents or access photos to import documents or extract signatures, the captured data stays on your device. We do not upload or share this data.
Purchases and Subscriptions
SignPaper offers in-app purchases and auto-renewable subscriptions processed entirely by Apple through the App Store. We do not collect, see, or store any payment information.
Children's Privacy
SignPaper does not knowingly collect information from children under 13. The app does not collect any personal information from anyone.
Changes to This Policy
We may update this policy from time to time. Any changes will be reflected on this page with an updated effective date.
