About this app

Ultimate photo lock and explicit content blocker tool.

Cover - Photo Vault is a unique photo lock tool. It helps keep your media content secure with the hide photos and videos feature. It is a secret photo vault and content blocker, keeping your phone clean from sensitive content 24/7.

It's the first video and photo vault tool with an automatic explicit content detection and content blocker feature.

Do you need content automatically blocked? With Cover, it’s easy. Inappropriate content, sensitive pictures & video files are detected and automatically moved to a secure folder. The best thing is that only you have access to the secure folder!

Secret Photo Vault + Automatic sensitive content blocker = Cover
If you need to hide photos and only you have access to the secure folder, our Photo Locker app with photo vault feature is great for you.

We know that you are busy and you don’t always have time to do it manually, Cover’s automatic explicit content blocker is made for you! Explicit content is blocked and moved to a secure folder, and you don’t need to do anything. Simple as that.

WHY COVER? -We’ve got you covered!

Your content stays yours, hide photos, underlock videos, and keep explicit content in a secure folder. Cover app locks your files in an encrypted secure folder photo vault with password protection (a PIN or a fingerprint).

There are hundreds of photo vaults out there. They all do the same thing so here's what makes this secret photo vault app different from a generic photo lock tool for Android:

Automatic Safe Gallery: sensitive pictures & videos are automatically
moved to a photo lock folder. No need to hide photos and video manually. Automatic content blocker!

Smart Notifications: Cover will subtly notify you if explicit content photos or videos are detected.

Instant Explicit Content Blocker: Cover can block any inappropriate pictures or videos sent via Messenger, Telegram, Whatsapp & other messaging apps!

Think of Cover as a safe photo lock app, which continually scans your device for explicit content - inappropriate images & videos and moves them to a secure folder. You don't need to manually hide photos with sensitive content inside a gallery vault anymore! Cover doesn’t even need internet access to work!

Real-time protection means that Cover runs 24/7 and does its best to hide pictures that are explicit content to your secure folder (gallery vault), keeping your phone "family-friendly" and your privacy protected.

Cover also has your messages protected. It will be automatically hiding or "covering" inappropriate pictures sent via Messenger, Whatsapp, Telegram, and more.

Automatic NSFW explicit content blocker and secret photo vault in one app. Hide photos in a secure folder and feel protected. We’ve got you covered!

Good app, only had 2 false positives out of almost a mix between 700 pics and vids... mostly pics. However the pictures still showed in the gallery and said "covered by cover" which was annoying. And so I decided I'd use a different app and wanted to "uncover" everything. So I selected everything at once and selected uncover but it only put like 10 things back to the way they were. I literally had to "uncover" stuff one by one... for almost 700 things. And when it came to the vids.... it slowed the app down... Because there would be lag because the app would be restoring the vid. Which wasn't even a big video btw. So it took almost 2 hours or more because the app kept freezing while I was uncovering stuff 1 by 1. It also didn't cover like 40 things that it should have. Overall the app did a good job detecting stuff to hide or whatever but definitely annoyed that I couldn't batch uncover stuff even though the app gives you the option I still had to undo stuff 1 by 1. Also no option to add stuff manually that the app missed. So if I have anything to say to people thinking about installing the app... I tried it thoroughly and it was a headache worse than what it's worth in the current state as of 12/17/18

Not sure if it actually detects anything NSFW because so far it hasn't found anything - I was mostly curious as to how many false positives it would flag - but I DID find that some pictures slow it to a CRAWL. I have some photos I took of caves on a trip I took ages ago and it is taking several hours scanning these. I left it running overnight and it managed to analyze four of them. So beware, pictures that don't have people in them but have skin-like tones might throw the app into a tailspin it can't recover from.

Till now the app has been working just fine. No hiccups. No unexpected shutdown. Any bugs encountered in future will be updated here. Edit1: This app can access all the corners and gets all those hidden thumbnails that are left back after the actual file gets deleted. Feature request-> show the metadata of the files that are being scanned and also the ones that gets selected for user review. We would like to know these hidden locations.
