DataStamp vs Pixveil

DataStamp is a local-first proof vault for creating verifiable timestamps for text, photos, screenshots, receipts, contracts, and files. The app computes a SHA-256 hash on your device, requests an OpenTimestamps proof, and lets you keep a portable record that can later be verified against Bitcoin anchoring. Your original content stays under your control; the proof is based on the hash, not on uploading the private document itself. What DataStamp does: • Create timestamp proofs for text, images, and files • Verify existing OpenTimestamps (.ots) proofs • Track pending and confirmed proofs • Organize evidence with folders and tags • Export/share proof material when needed • Use widgets and background checks for pending confirmations • Optionally sync your own records through your private iCloud account DataStamp is designed for people who want defensible records without depending on a central account, proprietary server, or mutable database. It is useful for preserving proof of existence for notes, creative drafts, legal or financial records, screenshots, business documents, research artifacts, and other digital evidence. OpenTimestamps is an open protocol for timestamping data with Bitcoin. DataStamp provides a polished iOS workflow around that protocol while keeping the app local-first and privacy-conscious.

Pixveil strips the hidden metadata from your photos before you share them — so you control what you reveal. Every photo your iPhone takes quietly embeds GPS coordinates, camera model, exact timestamp, lens settings, and more into the file. When you share that photo, all of it goes with it. Pixveil is the fastest way to see exactly what's hidden and remove it in one tap. View full EXIF metadata, grouped by category: · Location — GPS latitude, longitude, altitude · Camera — Make, model, lens, aperture, ISO, shutter speed · Date & Time — When the photo was taken and digitized · File — Dimensions, color space, file size Strip metadata instantly: · One-tap full strip removes everything · Selective strip (Pro) — keep GPS but remove camera, or any combination · Batch strip (Pro) — clean up to 60 photos in a single operation WHAT MAKES PIXVEIL DIFFERENT · 100% on-device processing — your photos never touch a server · Inspect before you strip: see exactly which fields will go · One-time Pro purchase — no subscription, ever PRICING Inspecting photos and the one-tap full strip are included at no charge. Pixveil Pro (selective strip, batch strip, and all future features) is a single one-time purchase — yours forever, with no subscription. FEEDBACK Questions, bug reports, or feature ideas?
