Where are my documents and data stored?
Doki works 100% locally on your phone. No personal documents, passwords, or data are ever transmitted to IANGINE servers or any third-party clouds.
How many passwords can I store?
Up to 10 in this version, in total, regardless of the holder. Deleting one frees up a slot.
How do I view or copy a saved password?
Using your fingerprint, face, or PIN. When copied, it is automatically cleared from the clipboard after 30 seconds.
Does the backup include my passwords?
Yes, if you leave "Include my saved passwords" enabled. If you turn it off, restoring that file will not erase the passwords already on your phone.
How do I share data for a family member or a vehicle?
Local backup → Share holder data. Send the file password through a different channel.
Can I recover my passwords if I lose my phone?
Only with a backup that includes them and its password.
What happens if I forget the password for a backup or shared file?
Nobody can open it, neither Doki nor IANGINE.
How do I rate the app or send feedback?
Profile → About.
What happens if I forget my PIN?
If you enabled biometrics (Face ID, Touch ID, or Android Biometric Prompt), you can use it to unlock the app. Because of our offline, zero-knowledge architecture, IANGINE cannot reset your PIN remotely.
How can I back up my documents and passwords securely?
You can generate an encrypted .doki backup file from Local backup. Be sure to remember the password you choose (minimum 8 characters), as nobody can open or restore it without it.
How can I delete all my data?
You can purge all stored data anytime from Profile → Delete all data, or by uninstalling the application from your phone. When deleting a password or holder, they are also removed from your phone.
