Redact Sensitive Media Before You Share It.

Redact photos, videos and PDFs, with photo EXIF removal and video metadata-removal options. Media analysis and redaction run on your device. Google ML Kit may send diagnostic and usage information to Google, and subscription verification uses online services. Review the exported copy before sharing.

Why Privacy Conscious Users Choose ShareMask

ShareMask analyses selected media locally. Its PDF export rebuilds pages as rendered images rather than retaining the source text layer.

🔒

Local Media Processing

Detection, OCR, face tracking, and rendering execute locally on your device. ShareMask has no remote media inference API and no user content database.

🎯

Multi-Format Support

Redact photos, videos, and multi-page PDF documents. Processing time and detection results vary with your device, file size, format and content. Review and adjust suggested masks before exporting.

🧼

Metadata Removal Setting

Metadata removal is enabled by default and can be changed in settings. The app clears photo EXIF and requests removal of video container metadata during export. Results can vary by format and export path. Inspect exported files when metadata is sensitive.

🛡️

Rendered Output Layers

Exports render your selected redactions into the output. Automated detection can miss sensitive details, and blur or pixelation may leave information recognizable. Review every export before sharing; use an opaque covering where details must be concealed. Originals and copies shared elsewhere remain separate.

Comprehensive Capabilities

Engineered for Every Sharing Scenario

Whether you're sending a quick family photo, sharing a street vlog, or forwarding medical or legal documents, ShareMask has purpose-built tools for the job.

Photo & Screenshot Redaction

ShareMask can suggest masks for detected faces, text, and barcodes. Processing time and detection results vary with your device, file size, format and content. Review and adjust suggested masks before exporting.

  • Mask Styles: Blur, pixelation and opaque blackout, with shape controls and an eye-bar option for faces.
  • Freehand & Polygon Shapes: Draw exact freehand masks or polygon boundaries around complex objects.
  • Generated Filenames: Exports receive generated filenames rather than the original source filename. Generated filenames include the export date and time.

Temporal Video Tracking & Audio Control

Video privacy made easy. The engine samples keyframes, tracks moving faces and objects through the timeline with linear interpolation, and renders smooth blurred ellipses.

  • Automated Motion Tracking: Follows moving subjects across video keyframes with occlusion hold.
  • Audio Control: Keep the original audio or remove the entire audio track during export.
  • MP4 Export: Export redacted video as MP4. Hardware encoding is attempted when supported, with a software fallback. Re-encoding may change quality, bitrate and file size.

Rendered PDF Pages

ShareMask analyses selected media locally. Its PDF export rebuilds pages as rendered images rather than retaining the source text layer.

  • Rendered PDF Pages: Rebuilds pages as rendered imagery where selected redactions are baked into the output.
  • On-Device OCR: OCR and text-pattern rules can suggest regions to mask; handwriting and signatures may be missed. Always review before exporting.
  • Multi-Page Support: Review and sanitize page-by-page before generating your clean PDF.

Batch Redaction for Photo Albums

Select multiple photos, review detected regions and masks for each image, then export the batch. Free supports up to 10 photos; Pro supports up to 1,000.

  • Sequential Processing: Photos are queued and processed sequentially on your device. Processing time depends on device capabilities and image dimensions.
  • Uniform Mask Presets: Apply blur, pixelate, or custom framing consistently across every item.
  • Free & Pro Options: Redact up to 10 photos per batch on Free, or up to 1,000 photos on ShareMask Pro.

Private Watchlists & Sensitive Identities

ShareMask can suggest masks for watchlist terms detected by text recognition. Recognition can miss or misread text; review and adjust suggested masks before export.

  • App-Private Storage: Projects, watchlist phrases, and privacy profiles are stored in app-private storage.
  • No Face Embedding DB: ShareMask never builds biometric facial databases or identity surveillance profiles.
  • Text-Pattern Suggestions: Text-pattern rules can suggest card-number, identifier and email regions to review. Matches may be incomplete or incorrect.

Three Steps to Safe Sharing

Select your media, review and adjust suggested masks, then export. Processing time varies with your device, file size and content.

1

Select or Share-In

Pick media from your phone gallery, or share directly from your camera, WhatsApp, Messenger, or Files app into ShareMask using the standard system share sheet.

2

Auto-Scan & Customize

On-device ML Kit highlights detected faces, sensitive text, and barcodes. Tap to confirm, adjust blur radius, draw custom polygons, or blackout additional details.

3

Export & Share Safely

Export a freshly rendered file with stripped EXIF/GPS metadata and flattened layers directly to your gallery or recipient app. Review the exported copy before sharing.

Architecture & Trust

Privacy Architecture

ShareMask runs media analysis and redaction on-device. The sections below explain local storage, SDK diagnostics, billing verification and sharing.

On-Device ML & Detection

On-device Google ML Kit detection and the bundled MoveNet head-detection model run locally on your device. Selected media is processed locally and is not uploaded to our servers for analysis.

Cloud Backup Exclusions

ShareMask configures Android cloud-backup exclusions for app-private data. Gallery/shared copies follow their destination's backup settings. iOS backup behavior is not yet verified for release.

No Ads or Behavioral Trackers

ShareMask contains NO advertising SDKs, NO behavioral trackers, and NO commercial data monetization. Core detection runs on-device, and third-party ML Kit diagnostics operate strictly under documented platform policies.

Stateless Billing Verification

When you purchase ShareMask Pro, Google Play handles transaction details. ShareMask sends only the purchase token to a stateless Prinix Labs Google Cloud Run verifier to confirm access. Your media is never involved.

Frequently Asked Questions

Clear, direct answers regarding ShareMask's privacy architecture, features, and technical mechanics.

No. Media analysis and redaction run on your device with no upload of your photos, videos, or documents to our servers. Google ML Kit may send diagnostic and usage information to Google. Purchases and subscription verification use online services.

Exports render your selected redactions into the output. Automated detection can miss sensitive details, and blur or pixelation may leave information recognizable. Review every export before sharing; use an opaque covering where details must be concealed. Originals and copies shared elsewhere remain separate.

Metadata removal is enabled by default and can be changed in settings. The app clears photo EXIF and requests removal of video container metadata during export. Results can vary by format and export path. Inspect exported files when metadata is sensitive. Exports receive generated filenames rather than the original source filename (including the export date and time).

Core media analysis and redaction run on-device. Google Play purchases, restoring/checking subscription access, reviewer access and SDK diagnostics use network services. Paid access may need to be verified again after restarting the app.

The local export receipt records selected export options, mask counts, output details and a file hash. It is not a certificate that every private detail or all metadata was removed. Review it before sharing: filenames, timestamps and custom profile names may reveal information.

Payments are managed directly and securely through Google Play. Prinix Labs operates a stateless verifier hosted on Google Cloud Run that queries the Google Play Developer API solely to validate your active subscription token. Your payment card information is handled entirely by Google Play.
