Terrible Privacy Policy

Kilonotes says it collects device and log info, including device model, operating system, unique device identifiers, login IP address, app version, network status, network quality, sensors such as gravity sensors, operation logs, SD card data, running processes, and service logs. It also says it may collect installed-app information, running-process info, or memory-stored data for security/malware prevention.

It requests permissions for things like local storage, camera, photo album, Bluetooth, microphone, foreground service/recording, and access to task information for app analysis. Some of that makes sense for a notes/PDF/recording app, but “access to task information” and running-app analysis is more invasive than I’d love for a notebook app.

If you are intending to use Kilonotes as a private journal, password storage, etc. I would steer clear.

Amazing!!

Im making a junk journal on it, and its overall amazing!! Its not my favorite for making the screens, but i write down things on ibis paint x, and i import it into my journal! Amazing quality, but i would add a feature so when you import a photo you have the option to make it fit the whole screen!

Only one complaint…

I just got the app and I think it’s pretty good but idk why but I’ve just have so much beef with the way my handwriting looks and it just keeps cutting off the beginning of my line and it makes me mad since I have to rewrite the same letter over and over.

Un reailable

Always dropping and I paid for a yearly subscription…. Can’t work on anything this way

Pretty good

Really good and fun to take notes! A lot of really good free stuff, some things are a bit difficult to figure out and the eraser and lasso tool kinda just pick up stuff near it but apart from that it’s good.
