Proton Blog: “The last thing you want when showing funny videos or holiday photos on your phone or tablet to friends and family is for them to see your sensitive and private photos. Although there are third-party apps dedicated to hiding your personal photos and videos, such as Vaulty(new window), LockMyPix(new window), and Gallery Vault(new window), these cost money and aren’t necessary. Almost all Android devices, iPhones, and iPads devices have pre-installed system apps that offer this functionality. Another option is to remove your private photos from your phone altogether and upload them to secure online storage that only you can access (such as Proton Drive).
