Information We Collect and Process

1) Files You Upload (Some Apps Only)

  • Files you select for processing (e.g., images, PDFs, videos, Word documents) may be temporarily uploaded to our secure servers only to complete your request where server-side processing is required.
  • All uploaded files are automatically deleted within approximately 2 hours after processing.
  • We never sell your documents or use them for advertising or model training.

2) Text You Enter (ScamShield AI)

  • ScamShield AI analyzes only the text you paste into the app. The text is processed locally on your device.
  • ScamShield AI does not upload message text to our servers and does not share message text with any third-party AI service.
  • If you enable History, scan results are stored locally on your device and can be cleared at any time.

3) Diagnostics and Usage Data

  • Limited, non-identifying data (e.g., error logs, device/OS version, timestamps) may be collected to maintain reliability, security, and performance.

4) Payments

  • Purchases and subscriptions are processed by Apple App Store or Google Play. We do not store credit card numbers.

5) Advertising and Analytics (AdMob)

  • Some apps display ads via Google AdMob. AdMob may collect device identifiers (e.g., IDFA/AAID), approximate location (derived from IP), app interaction, and performance data to provide and measure ads.
  • You can reset or limit ad tracking in your device settings. If you purchase a "Remove Ads" option (where available), the app stops requesting ads.

Permissions We Request

  • Files / Storage: to allow you to select photos, videos, or documents for processing and save results locally.
  • Camera (optional for certain apps): to capture a new photo or video if you choose to do so inside the app.
  • Internet Access: to securely upload files for processing and deliver results where applicable. ScamShield AI does not require internet for pasted text analysis.

How We Use Information

  • Provide the services you request (e.g., conversion, compression, editing).
  • Provide message risk analysis in ScamShield AI using on-device processing.
  • Improve app reliability, security, and user experience.
  • Respond to support requests you send us.

Sharing of Data

  • We do not sell or trade your data.
  • We may share limited data with trusted service providers (e.g., cloud hosting for file processing apps, error monitoring, ad networks for apps that show ads) strictly to operate our apps, under confidentiality obligations.
  • ScamShield AI does not share message text with any third-party AI service or external processing provider.
  • We may disclose information if required by law.

Data Retention

  • Uploaded files are automatically deleted within ~2 hours after processing (where uploads are used).
  • ScamShield AI: pasted message text is processed locally. Optional scan history is stored on-device and can be deleted by clearing History.
  • Diagnostic logs are retained only as long as needed for operations and security.

Security

  • We use HTTPS for secure transfers where supported.
  • Access to systems is restricted to authorized personnel.
  • No method of transmission or storage is 100 percent secure, but we use industry-standard safeguards.

Children's Privacy

Our apps are not directed to children under 13 (or under 16 in the EU). If we learn that such data has been provided, we will delete it promptly.

App-Specific Notes

ScamShield AI

  • ScamShield AI analyzes only the text you paste into the app, on your device.
  • Message text is NOT uploaded to our servers and is NOT shared with any third-party AI service.

Google and its advertising partners may process device or advertising identifiers, IP address, ad interactions, consent choices, and diagnostic information to provide and measure ads. Processing and ad personalization depend on your settings, location, and consent choices.
  • Apple App Store or Google Play processes in-app purchases. We do not receive your full payment card details. The store may provide purchase information needed to enable or restore a purchase.
