About PreCloud: Encrypt file & note
Encrypt before upload
---
Encrypt your files and notes before uploading them to cloud.
Open source, no tracking and free forever.
(In-app-purchase is only used for donation)
PreCloud has no server, everything happens on your device: your passwords, the encryption process, the encrypted files and notes.
You can safely upload the encrypted texts or files to wherever you want, making any cloud provider an encrypted storage.
---
Everything is encrypted by the very well established algorithm PGP. The algorithm is used by Proton, Mailvelope, Encrypt.to and many others.
---
You can also generate strong password now;
You can encrypt large files up to 1GB now;
---
NOTE: Please keep your master password in a safe place, like a password manager. If you lose it, you can NOT decrypt your texts and files!

PreCloud 1.14.0: Merge notes and files
There is no Notes tab anymore. (But your notes are not lost!)
All notebooks are moved to the Files tab, so notebooks also become folders. And in each folder, there is a Notes section, and a Files section.
The reason: As I use PreCloud more and more, I find myself creating notebooks and folders with the same name, like "Work", "Family", "Xiangcai".
It's just easier to have everything in one place.

So here you have it! You can now donate with in-app-purchase!
Some other improvements:
Randomise your files in a folder to view;
Download remote files, so files never leave PreCloud;

PreCloud has no cloud, all encrypted files and notes are saved on your phone. If you lose your phone, you lose everything.
This version deals with this problem.
I introduced a "Backup" screen, where you can zip everything and share it to any cloud storage.
Of course, you can import the backup.
You can find the Backup screen at "Settings -> Backup".
---
Other improvements:
- Preview decrypted file if it's image or video;
- Move folders;

1.10.2
2022年10月25日
This release introduces sub-folders for files encryption.
I was wandering in a forest nearby during the weekend, and took a lot of photos with PreCloud. I have a "Travel" folder, so all photos are saved here.
But this folder becomes unmanageable very quickly, because everything can go here.
I need make it possible to create sub-folders within a folder. That's what I did in the past 2 days.
Now I have 2 sub-folders within "Travel".

- You can now empty a folder;
- Now the App size decreased dramatically (from 80MB -> 20MB);
- But you can now encrypt bigger files, 200MB;
- And you can Move or Delete file in the decryption modal, so it's easier to organise your files;

In version 1.9, I introduced notes and notebooks, so you can organise your notes well;
In version 1.10, it's all about file folders.
Until now you can use PreCloud to encrypt and decrypt files, but you need to decide what to do with the files immediately, PreCloud doesn't store your files.
Now you can create file folders, and the encrypted files will be saved in those folders. Next time you open PreCloud, the files are still available in the app.

This version introduces a very important change: Notebook.
Previously I introduced the rich text editor, in which you can insert images, so you can create blog / diary like notes.
[Btw, I always want to build a note taker that can insert images :)]
And in this version, you can organise your notes in different notebooks.
Hope you like it!
I moved the plain text encryption into the settings screen, to make the notes screen clean.

In this version I re-worked the rich text editor:
1. You can Insert images now (Maximum of 10 images though);
2. The note now will be encrypted and saved on your phone as a file (file extension .precloudnote);
3. I added the plain text encryption back, so if you just want to encrypt some text, go here;
4. I also re-worked the navigation in the app;
My goal with rich text note is, you can take all your private notes here and feel safe about them.

Until now, the text editor is very basic, you can only type, there are no formats.
In this version, I implemented a text editor. You can add list, intent the list, make text bold, strikethrough it and etc.
This is the start of the text editor, I will keep improving it (for example insert images) Stay tuned.
