PrivyMark scans your photos for the private details you might accidentally share — a face in the background, an email or phone number in a screenshot, a card number on a receipt, an address on a shipping label — and helps you cover them in one tap before you post, message, or send. Everything happens on your iPhone. Your photos are never uploaded, and PrivyMark doesn't collect, track, or store anything about you. SCAN FIRST, NOT JUST BLUR • On-device detection for faces, QR/barcodes, emails, phone numbers, URLs, street addresses, card-style numbers, ID/passport numbers, order and tracking numbers, and names • Every match is shown as a suggestion you can review — turn any of them on or off before you export • Low-confidence matches are labeled "Maybe" instead of silently covering — or missing — something COVER IT YOUR WAY • Solid block — the safest option, fully opaque and irreversible • Pixelate or blur — for a softer look (these can sometimes be reversed on text, so text defaults to solid block) • Hide Text — blends a text region into its background so it disappears in place • Marker — freehand strokes for anything the scan missed • Faces get a fun emoji cover by default — tap to swap the emoji, drag to reposition FIX WHAT THE SCAN MISSED • Long-press any line of text to "explode" it into individual words and cover just the parts that matter • Draw your own box around anything, anywhere • Pinch to zoom in for pixel-precise touch-ups • Full undo/redo CLEAN UP METADATA, TOO • See exactly what's hiding in the file — GPS location, device model, timestamps, and more • GPS is stripped by default; choose what else to remove • Optional check for hidden pixel-level watermarks some apps embed in screenshots (best-effort — see note below) SHARE FROM ANYWHERE • Send a photo to PrivyMark from the share sheet in Photos, Messages, or any app • Scan, cover, and share back out without leaving your flow 100% FREE • No account, no subscription, no paywalled tools, no watermark added to your exports • Every detection type and every cover style is free, forever MADE FOR iOS • Universal app for iPhone and iPad • VoiceOver labels and Dynamic Type support throughout • Works fully offline, including in Airplane Mode BE HONEST ABOUT LIMITS PrivyMark's scan is a smart assistant, not a guarantee — always review its suggestions before you share. Pixelation and blur can sometimes be reversed on text, which is why text defaults to a solid cover. The hidden-watermark check catches simple pixel-level tricks; it cannot detect or remove professional forensic watermarking designed to survive edits. PrivyMark never uploads your photos, doesn't use ad or tracking SDKs, and doesn't collect analytics of any kind. Every feature is free. If PrivyMark saves you trouble, Settings has an optional "Buy Me a Coffee" tip — it unlocks nothing, removes no limits, and changes nothing else in the app. Privacy Policy: https://privymark.o-c.do/privacy Terms of Use: https://privymark.o-c.do/terms
One Video Player

One Video Player turns your device into a video player that understands what it's playing. Even for videos that have no subtitles at all — or when you just can't find the right subtitle file — it generates subtitles live from the audio, right on your device, as it plays, in dozens of languages. Those subtitles are then translated into your own language, also entirely on your device. No upload. No account. No subscription. The player is free, and your first 5 videos include live subtitles and translation at no charge. After that, a single one-time unlock keeps them forever. Full real-time subtitle generation and translation require iOS 26 or later. On older devices, this live on-device processing may cause noticeable battery drain, heat, or slowdowns.

Verdict
The clearest difference is in-app purchases: PrivyMark at none against One Video Player's 1. PrivyMark also leads on iOS requirement (17.6 vs 26.0). One Video Player's advantage is update cadence (weekly vs monthly). On price, ads and device support there is nothing between them.
