Please check out the FAQ below:

Q: What Files Can I Encrypt With This App?
A: You can encrypt any file type you want. That includes Pictures, Videos, Text, APKs, documents, PDFs etc. As long as it's in your device, it can be encrypted.

Q: How Do I Encrypt?
A: ZenCrypt supports encrypting using an alphanumerical password, or using a fingerprint, if your device supports it.

Q: How Robust Is ZenCrypt?
A: Although ZenCrypt is a very powerful tool and the encrypted files are very well protected against attacks, I can not guarantee the robustness of this app. What I can guarantee, is that I put a lot of effort to provide a more secure option for storing your files.

Q: Can Other Devices Decrypt?
A: As long as they have ZenCrypt installed, and the same password is used (either plain or in fingerprint configuration), absolutely.

Q: Can I Share The Encrypted Files?
A: Yes. You can share them just like any other file, without worrying for your personal data.

Q: Can I Encrypt From External Storage?
A: Yes you can. ZenCrypt supports both internal and external storage, such as micro sd cards, usb, hard drives. You can also encrypt from cloud providers such as Google Drive.

Q: Is My Password That I Used For Encryption Stored?
A: No, and it never will be. ZenCrypt will never have an Internet permission, so your password and files will never be sent anywhere.
