## Description

Secure Memo is a powerful Chrome extension designed to keep your notes private and secure using AES encryption and password protection. It safeguards your sensitive information by encrypting notes with system-assigned keys and tracks unauthorized access attempts with timed lockouts after multiple failed logins. Users can easily edit, delete, share, and prioritize notes by urgency, filter notes by priority, and export/import encrypted data for backup or device changes.

The free version supports up to 50 notes, while the Premium upgrade removes ads, allows unlimited notes, enables the use of personal encryption keys, and offers advanced features such as search, adjustable session duration, text size, and automatic backup settings. Notably, all encrypted data is stored locally on your device for ultimate privacy, ensuring only you have access. With user-friendly design and strong security measures, Secure Memo is ideal for anyone seeking to protect their confidential notes effortlessly.

## Review summary

Users appreciate Secure Memo for its strong encryption, ease of use, ad-free experience, and reliable security for sensitive notes. However, common issues include a cramped editing interface, inability to recover forgotten passwords, difficulty recovering notes after app deletion, and concerns that shared notes may be exported unencrypted. Overall, it's valued for secure, small-note storage but could improve usability and data recovery features.

### Pros

- The app is highly secure with strong encryption and password protection.
- It is free, easy to use, and has no advertisements or bloatware.
- The app is reliable and trusted by long-term users for storing sensitive information.
- Good technical support and user satisfaction are reported.
- Suitable for keeping small notes safe and accessible on the device.

### Cons

- The editing window is too small and scrolling through larger notes is difficult.
- There is no option to recover or reset a forgotten password, risking data loss.
- Accidental deletion of the app results in permanent loss of stored information without recovery options.
- The app’s sharing feature exports notes in clear text, which may compromise encryption during data sharing.
