How does Guest mode work when I hand my phone to someone?
Open a set or pick specific photos and start Guest mode before handing your phone over. The viewer can only swipe through the photos you selected, and exiting Guest mode back to the rest of the app requires your PIN or biometric unlock.
What is the difference between 'Move' and 'Copy' when importing photos?
Copy imports your selected photos into the private Only These sandbox while leaving the originals in your phone's photo library. Move imports the photos and removes the originals from your camera roll so they only live inside your locked sets.
Can Drawcode see or recover my photos if I forget my PIN?
No. Because Only These has zero network access and stores your PIN as a one-way salted PBKDF2 hash in your device's hardware Keystore or Keychain, no one (including Drawcode engineers) can bypass the PIN or recover your photos without it.
How do .otvault backup files work?
An .otvault file is an AES-256-GCM encrypted archive containing your sets, photos, videos, and organization. When you export a backup, you choose a passphrase that derives the encryption key via PBKDF2. You can store the .otvault file anywhere, and restore it later on the same or a new device using that passphrase.
Does Only These connect to any cloud server?
Never. The app does not request the INTERNET permission on Android and makes zero network requests on iOS. It operates 100% offline.
