Is Vault safe to use? Will it delete my photos or videos? medium
According to 2 of 5 sampled recent reviews, users have experienced irreversible data loss where the app auto-deleted saved videos or made photos/videos inaccessible. One reviewer lost approximately 100 videos saved over two years. The app's own description warns that some cleaning apps may delete Vault's data folder, which could explain some cases, but the user reports in the sample do not cite cleaning apps as the cause.

Does Vault have ads? medium
Yes. Two of 5 sampled recent reviewers describe the app as having forced, intrusive ads that appear on nearly every screen (home screen, settings, within other apps) and are easily triggered by pressing the wrong button. One reviewer notes the paid version (ranging from $0.99 to $30.99 per item) removes ads but is considered too expensive.

Can I recover my photos if I forgot my Vault password? high
According to the app description, you can reset your password if you set a security email beforehand. If you did not set a security email but backed up your data to the cloud, you can recover data by reinstalling the app and restoring from the cloud. The app also offers a 'Forgot Password' entrance after entering the wrong password.

What is Stealth Mode in Vault? high
Stealth Mode makes the Vault icon disappear from your home screen. To access Vault again, you can add a Vault widget back to your home screen or download the companion app 'NQ Calculator' from Google Play and enter your password there. This feature is described in the app's official description.

1★This app auto deleted all my videos that I saved over the course of two years, approximately 100 videos...just gone! There is no customer service option to even try to troubleshoot the issue. These were irreplaceable videos! I am just left with nothing, all the memories lost. I would not recommend this app at all. PS Latest update doesn't eve open app. It just crashes.

3★This was my go to app until they forced a feature where I would swipe from one of the bottom corners that had shortcuts for quick settings and was forced to show ads. So there was an ad no matter where I was, home screen, settings, any app. I couldn't find an option to turn it off in the vault settings. I hope you guys stop trying to expand on where you are not needed. I downloaded this for a secure media vault, nothing else.

2★It does the job well but it's a minefield of ads. I don't mean a few ads, I mean if you press the wrong button (which is easy to do), you've opened an ad up. The pay version is too expensive to purchase so you're left with this nightmare of ads to navigate. I would try another app but this one does work the best. You say you removed the ads from my account. How? I just opened the app and it's an avalanche of ads! I understand that you need to generate money but this is ridiculous

3★I had an issue when I got a new phone and tried to transfer my paid application over. They responded quickly and explained how to activate the premium version on my new phone. ** Update** I wish I could press and hold on messages or call log items to select, then select multiple items to delete all at once. Currently I have to delete one at a time which is a PIA. The SMS also does not seem to be able to import my side of the conversation, it only imports the hidden contacts side which is also a PIA. I cant even select my messages to import. Its still a decent app though.

2★Not loading or importing.... All of a sudden I can't get to any of my photos or videos. I also can't import new ones. Please fix this issue without me losing all my pics/videos. I have pics/videos of lost loved ones that were too painful to see on a daily basis. Please help! I've had this app for over 5 years and am even a upgraded paid "member." I've never had a problem before now.
