Your book, safe and in your hands
Your book is stored on your phone, locked for you, and nothing is erased in secret. And if you ever leave, you take it with you.
On your phone, offline
Accounts, entries and photos are stored on your phone. It works fully offline; the internet is only for online features.
- A database on your device
- No account needed
- Works wherever you are
A backup, with a password
One file with the whole book and its photos. With a password it is encrypted (AES-256) and only you can open it. Restoring never deletes anything.
- AES-256 encryption with your password
- Export as PDF, Excel and CSV
- Restore without erasing
Nothing is erased in secret
A recorded entry is never deleted: a correction is a reversing entry with a reason, and every change is in the activity log.
- An activity log that can’t be edited
- Cancel with a reason
- The statement stays honest
Fingerprint lock
Fingerprint, face or PIN, with auto-lock.
Encrypted chats
Mudir chats are encrypted per user.
No ads, no tracking
No analytics tools inside the app.
Your data is not a hostage
Reading and export are never locked.
Common questions
Where is my book stored?
On your phone. The book only goes online if you turn on an online feature.
Are there ads or tracking?
No. There are no ads, and no analytics or tracking tools inside the app.
What if I forget my backup password?
Nobody can open it, not even us. So choose a password you will remember, or keep a copy without a password somewhere safe.
If my plan ends, is my book locked?
No. Reading, export and backup are never locked.
