Encryption Algorithm Question

[Braddock]

Dear Encryption Chat support,

I would like to ask you one important question.

Is the (Samsung Notes App) suitable for storing sensitive information?
Are these "password-protected" notes really encrypted?

As encryption experts, do you have an idea about which encryption algorithm they might be using on this App?

I am asking you guys this question because I am a Samsung smartphone user, and I have a lot of important Data stored in this particular Samsung App.
And I am asking you because you guys are experts in the encryption field.

I really would like to know whether this "Samsung Notes App" is safe or not.

I just need to know so I can look for a more secure App if I have to.

One thing that bothers me the most is that Samsung at their website doesn't provide any information regarding the encryption algorithm (if any) they use to safeguard the contents stored in this App.

They should have available at their website a whitepaper explaining this App encription to us Samsung users, but they don't.

I don't know if they use for this App: AES 128-bit, AES 256-bit, Twofish, Serpent, or another encryption algorithm, etc. Therefore I don't even know if it is secure.

Perhaps I should stop using this App and migrate to a more transparent App in terms of its encription algorithm.

Please let me know guys, this is truly important to me and I need to have a good understanding about it, whether this App is suitable for storing sensitive information or not.

Thank you so much.
