### 5/5 — Tested – Totally Private!

*2025-04-02*

I tested it myself — none of my data gets uploaded, which gives me real peace of mind. The share feature is super useful too. I can send a note to a friend, and as long as we’ve agreed on a password ahead of time, they can unlock and read it. It’s a really convenient and secure way to share private info right from your phone.

**Developer response:** Thank you so much for your kind words and thoughtful review! We're thrilled to hear that the app gave you peace of mind and that the private sharing feature worked well for you. Your trust means everything to us, and we're committed to keeping your data safe and offline — always. If you ever have feedback or ideas, feel free to reach out anytime!

### 1/5 — Bug

*2024-07-19*

I have tried for a long time to paste a long and complex password to my first nook without success. I am unable to get the context menu to be able to paste in the password text field, the keyboard pops up and disappears.

**Developer response:** Hi there, thank you for your feedback and sorry for the inconvenience you experienced. We’ve identified and fixed the issue you mentioned regarding the paste function in the password field. The fix has been released in the new version 1.3.2.

We appreciate you taking the time to report this. If you’re still experiencing any issues, feel free to reach out—we’re here to help!

Thanks again for helping us improve the app!
