You can create files but you can’t move them. This needs way more work to be useful in any way. ### 5/5 — If you are deciding between apps to encrypt files or even text go with this one become a believer *2024-08-01* Absolutely outstanding app don’t hesitate If you are looking to encrypt files or even text this app makes an absolute breeze. I can’t imagine any possible way encryption on iOS could be made simpler or more user friendly and the fact that it’s offered absolutely free without in app ads or purchases even when the majority of similar apps I found at the time of writing this review that do the same thing weren’t or collected user data and static and more often than not both is jaw dropping in itself. If you have any reservations about this app over ANY similar app on the App Store I strongly encourage you to download this one instead you won’t regret it and save money and preserve your privacy at the same time. ABSOLUTELY PHENOMENAL WORK👏🏻👏🏻THANK YOU! ### 5/5 — Simple, responsive, does what it says it does. *2023-05-15* If you’re looking for a quick easy way to make encrypted notes that’s open source, this is it. The additional features (being able to use multiple encryption phrases, being able to share/store/send encrypted notes elsewhere from the app…) are just the icing on an already-delicious cake. And there’s a cute cat! What’s not to love!? ### 5/5 — PGP app *2023-03-16* This is a great utility for data security. Need to add more features. ### 5/5 — Good to see an open-source app *2022-08-27, version 1.2.6* I download this app today and I understand that it is in the early stages of developing. It does have alot of potential for being a great app so keep it up and add more features. Thanks for your work. **Developer response:** Thank you Behrad! ## Frequently asked questions about PreCloud ### What is PreCloud?

(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. --- Receive updates: www.getrevue.co/profile/precloud ### 1.13.0 — 2022-11-05 Someone asked me to add the in-app-purchase for donation (see here: https://github.com/penghuili/PreCloud/issues/3) 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; --- Receive updates: www.getrevue.co/profile/precloud ### 1.12.0 — 2022-10-30 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; --- Receive updates: www.getrevue.co/profile/precloud ### 1.11.0 — 2022-10-30 Encrypt real large files, up to 1GB In last version I increased the encryption size from 20MB to 200MB. In this version, it jumps to 1GB. Happy encrypting! Receive updates: www.getrevue.co/profile/precloud ### 1.10.2 — 2022-10-25 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".
