Clavis (Passwords Manager)

Clavis stores in a file encrypted by AES algorithm (Rijndael-256), a list of records containing Users or identifiers (ID) associated with a Password or Payment card.

The vast majority of websites and internet portals require registration to enjoy all its content.
Due to the large number of websites visited in which it is necessary to be registered with a username and password, it is normal for you to use the same users and passwords for all those websites.
As a rule, attacks and hacks occur on the servers of websites and internet portals through which criminals can obtain the passwords of all their users.
Administrators sometimes do not inform users and may force them to change their password to a different one.
The criminals will know their access credentials, which will be the same as those used for many other websites. They know this situation and will not hesitate to take advantage of the juicy information obtained.
To avoid that situation, it is best to have a different password on each website without having to remember them.
Clavis is responsible for storing and reminding them wherever you are.
You will only have to memorize a single strong password that will serve as the master password.
Likewise, it is also recommended to have your credit card information ready but secure.

Clavis consists of a list of "Records" that contain "Users/ID" associated to "Passwords" or "Payment cards".
You can define the name of each record with the name of the desired website, and within that record one or more "Users" or "ID".
You can use the application to enter what you want, the only restriction is that only a password or card can be associated with a user.
Example with email:
Record: Gmail
User/ID: abc@gmail.com
Password/Key: 12345678
Example with website:
Record: Amazon
User/ID: Fulanito
Password/Key: qwerty
Example with bank card:
Record: Bank of America
User/ID: Online card
Number: 1234 5678 9012 3456
Expiration day: 08
Expiration month: 09
Expiration year: 2040
CSC/CVV: 123

The list of records is stored encrypted in a records file.
The file is saved in the local storage of the device.
To ensure the persistence of this records file, the application allows you to synchronize it online using a Google Drive account (cloud storage).
If you have a Google account, then you also have access to Google Drive through that account for free.

Unlike other similar applications, Clavis does not use third-party servers or require registrations on pages of dubious trust.
Your passwords and keys will be in your Google Drive account and in the internal storage of any device you choose.

The application has a security lock that prevents a user from uninstalling it or modifying its settings without authorization. To activate it, the following permissions are required and must all be authorized:
- Device administration.
- Accessibility service.

The Premium version gives you the following improvements:
- Removal of ads.
- A great password generator with multiple options.
- Unlimited number of records (The free version has a limit of 8 records without ads).
