PDF Signature Validator

Privacy Policy

Last Updated: July 07, 2026

At PDF Signature Validator, we are committed to protecting your privacy. This Privacy Policy explains how we collect, use, store, and protect your information when you use our mobile and desktop application.

By using PDF Signature Validator, you agree to the practices described in this Privacy Policy.

1. Information We Collect

Local Document Processing (Privacy First)

PDF Signature Validator is designed with a privacy-first approach.

No File Uploads: All core PDF utility operationsβ€”including viewing, editing, converting (Image, Word, and Excel to PDF), merging, splitting, compressing, page managing, and ID card to PDF creationβ€”are performed locally on your device.

We do not upload, store, access, read, or share your PDF files, images, documents, or scanned files on our servers. Your documents remain entirely on your device unless you choose to share or export them using your device’s sharing options.

Digital Signature Verification

Cryptographic signature verification is handled entirely on-device using our local trust store certificates and cryptographic methods. No details, certificate data, signer credentials, or verification results about the documents being validated are sent to us or any third party.

2. Optional Account & Profile Information

Core PDF utilities and signature validation work completely offline without requiring an account. However, you may choose to sign in with Google to sync your Pro subscription status, save your verification credits, and back up signatures across devices.

  • Information We Store: If you sign in, we securely store your basic profile details (Name, Email address, Profile photo URL, and optional WhatsApp/phone number for priority support) in Google Firebase.
  • Account Deletion: You have full control over your data. You can permanently delete your account and all associated data anytime directly within the app under Settings > Delete Account & Data.

3. Payments and Subscriptions

PDF Signature Validator offers optional in-app purchases and auto-renewable subscriptions (such as Monthly and Yearly Pro Plans) to unlock unlimited document verifications and an ad-free experience. If you choose to subscribe:

  • Payment Processing: All payments and transaction details are processed securely by the Apple App Store (for iOS/macOS) or Google Play Store (for Android). We do not collect, store, or have access to your credit card, bank details, or billing information.
  • Auto-Renewal: Subscriptions are auto-renewable and will automatically renew at the end of each billing cycle (e.g., monthly or yearly) unless auto-renew is turned off at least 24 hours before the end of the current period.
  • Billing: Your App Store account will be charged for renewal within 24 hours prior to the end of the current billing period.
  • Management & Cancellation: You can manage your subscriptions and turn off auto-renewal at any time by going to your App Store or iTunes Account Settings after purchase.

4. Third-Party Services & Advertising

To provide free features, analytics, and diagnostics, we integrate trusted third-party services:

Google AdMob (Advertising)

For free tier users, we display advertisements via Google AdMob. AdMob may use device advertising identifiers (such as IDFA on iOS or GAID on Android) in accordance with Google's policies and your device privacy settings. Pro subscribers enjoy a 100% ad-free experience.

Google AdMob Policy: Google Ads & Privacy.

Firebase (Diagnostics & App Performance)

We use Firebase Authentication, Firestore, and Firebase Crashlytics to securely authenticate users, sync credits, and collect anonymous error logs. This diagnostic data is anonymous and does not contain any file content or document data.

Google Privacy Policy: Google Privacy & Terms.

5. Permissions Used by the App

PDF Signature Validator requests specific device permissions only when required to perform operations you initiate:

  • File and Storage Access: Used to select, open, process, save, or export PDF files and documents.
  • Camera or Photos Access: Used only when you choose to create PDFs from images, scan physical documents, or create ID card PDFs.
  • Internet Access: Used solely for checking app updates, diagnostics, and performance logs. Document processing never transmits data over the Internet.

6. How We Use Information

If any anonymous diagnostics or crash reports are collected, they are used solely to fix application crashes, bugs, and errors; improve performance, stability, and speed; and maintain general security. We do not collect, sell, rent, trade, or share any personal information.

7. Data Security

We implement standard technical measures to protect any anonymous diagnostic data. Since your PDF documents are processed locally on your device, we have no access to them, and they are protected by your device's operating system security.

8. Children’s Privacy

Our services are not directed to anyone under the age of 13. We do not knowingly collect personal information from children under 13.
