Wolf Gallery
Encrypted, offline photo & video vault with a comfortable gallery
新版本 4.1
Every file can now show what it carries. The details dialog reads the shot out of the photo itself — date taken, camera, aperture, shutter, ISO, focal length, flash and coordinates — and a second screen opens the file completely: EXIF, IPTC, the ICC profile, XMP, the chunks of a PNG and the container of a video. Blocks that are closed or specific to one vendor are listed by name and size and never opened.
New ways to sort: by size, largest or smallest first, by album across the whole vault, and

Wolf Gallery is an offline gallery that keeps your photos and videos encrypted on the device.
Each file is stored as ciphertext in the app's private storage, so other apps and the system only ever see encrypted data. Files are decrypted on demand, including when you share to another app or set a wallpaper, so your media is never written out in the clear. You can use it as your main gallery or keep it next to the stock one as a private vault.
Development is active and ongoing.
Security
Every file is encrypted in an isolated vault inside the app's private storage. There is no internet permission and no accounts, cloud, telemetry or trackers, so the app simply cannot reach the network. Encryption uses authenticated AES-256-GCM, so any tampering is detected on decryption, and keys are derived from your passphrase with Argon2id, the memory-hard winner of the Password Hashing Competition. Your passphrase is never stored. The vault key is wrapped with an Argon2id key on top of the hardware-backed Android Keystore, so both the device and your password or PIN are needed to decrypt. The vault is symmetric-only, which makes it quantum-resistant by design, and a native crypto core zeroes key material in memory after use. Screenshots and Recents previews are blocked, wrong unlock attempts are slowed by exponential backoff, and an optional wipe after a set number of failures is available. A built-in self-test screen runs the crypto, file-format and migration checks right on your device.
Organize
Create groups and albums inside the app and rename anything, including with emoji. Sort, search and pin your groups, albums and files, set an album cover from any picture with adjustable framing, and import or export on your own terms — a whole group leaves as a folder with a subfolder per album. You can share to other apps or set a wallpaper directly from the vault.
Appearance
Choose from several themes, including pure-black dark modes, paired with a custom accent color. Adjust the grid density, switch thumbnails and albums between rounded and square corners, and place the action bar at the top or the bottom to suit your grip.
Other
A built-in trash keeps deletions undoable, a first-run wizard makes setup effortless, and the app is available in several languages with more translations on the way.

Added export of a whole group: it leaves the vault as one folder, with a subfolder for every album inside it.
Existing features have been improved and a number of bugs fixed. Translations have been refined throughout.

新版本 1.3.9
Large photos and videos now import reliably. Encryption inside the vault was rebuilt to work through a file in small pieces instead of holding all of it in memory at once, so file size is no longer a limit. Imports that used to fail on big videos go through, and they finish faster than before.
Video playback changed with it. A video is now read straight out of the vault as it plays, piece by piece, so it no longer has to be decrypted into a temporary file before it starts. That temporary copy i
