About this app

Detaggo gives you full control over your image metadata — view every hidden tag, edit or strip what you want, sign photos with Content Credentials, and protect your work with watermarks. All in one app that runs entirely on your device.
🔍 VIEW & EXPLORE METADATA
Open any image to see all its embedded metadata, organized into clear categories: camera info, shot settings, date, GPS location, software, XMP, IPTC, C2PA, maker notes, and more. Search and filter by category. AI-content flags and GPS coordinates show at a glance, and C2PA provenance is marked AI-generated or human-signed.
✏️ EDIT & ADD TAGS
Tap any tag to edit values across 14+ categories with inputs matched to each data type. Add new tags from the EXIF catalog or create your own. Save as a copy or overwrite the original.
✅ C2PA CONTENT CREDENTIALS (PREMIUM)
Sign your photos as human-signed Content Credentials to prove they're real. Mint a signing identity or import your own (PEM/PKCS#12, EC P-256 / ES256), then sign single images or batches. Identities are backed up to Google Drive.
🤖 AI CONTENT DETECTION
Scan images for AI-generation signals across 11+ signatures, including DALL·E, Midjourney, Stable Diffusion, Adobe Firefly, and more — each with a clear confidence rating. It also tells AI-generated photos apart from human-signed ones.
🧹 CLEAN & STRIP METADATA
Choose what to remove: AI tags only, AI + C2PA, AI + software signatures, human-signed C2PA, or a full metadata wipe. Preview the tag count and file-size savings before applying.
📤 SHARE TO AUTO-CLEAN
Share any image into Detaggo to auto-strip its metadata by your chosen profile, then forward it, open it, or discard it. Free daily cleans, unlimited with Premium.
🧭 PRIVACY PRESETS
Build reusable presets that strip the right metadata for each destination — dating apps, marketplaces, social — and apply them in one tap.
📋 COPY METADATA BETWEEN IMAGES
Copy all metadata or pick specific fields from a source image to one or many targets in a single pass.
🕓 TIMEZONE DETECTION & FILLING
Derive the image's timezone from GPS, EXIF offset, or XMP using confidence-weighted methods, then fill the missing pieces automatically.
💧 IMAGE WATERMARKING (PREMIUM)
Protect your work with multiple watermark styles:

- Visible overlay: text or logo with control over size, opacity, rotation, blend mode, and tiling
- Blind DCT: embed an invisible payload that survives JPEG re-compression; extract without a key
- Keyed DCT: hide a payload behind a shared passphrase so only the correct key can recover it
- RSA-2048 signature: sign with a private key, verify authenticity with the public key, export a PDF report
- Survival test: run an attack battery, score how well a watermark holds up, and export a PDF report
- Key management: generate, import, export, and switch keypairs, with encrypted backup to Google Drive
- Watermark Vault: store watermark configs and thumbnails for later re-editing

📍 VIEW & EDIT GPS
View, edit, or delete coordinates (latitude, longitude, altitude, speed, direction). Pick them on a map, or open in your system maps app.
🔒 ENCRYPTED VAULT
Store sensitive images in a local encrypted vault. Choose full-image storage or thumbnail-plus-reference mode.
☁️ GOOGLE DRIVE BACKUP
Sign in with Google to two-way sync vault entries, watermark keys, signing identities, and history, with user-controlled conflict resolution.
📦 BATCH PROCESSING
Operate on many images at once — strip metadata, AI tags, GPS, or C2PA, or add tags — with per-image success/failure reporting.
📈 ACTIVITY & INSIGHTS
A home activity feed tracks what you've cleaned and signed, with streaks, a weekly summary, and bytes saved.
🎨 DESIGN & LANGUAGES
A modern Material 3 interface with light, dark, system, and dynamic-color themes, plus tablet and foldable two-pane layouts. Available in English, Thai, Vietnamese, and Romanian.
🛡️ PRIVACY FIRST
Everything runs on your device. No images are uploaded. No data leaves your phone.
Detaggo — De-tag and go.
