Bonne Application

bonne application, cependant il serais très bien d'avoir une traduction en français, pour les non anglophones. Je suis pour l’instant, complètement bloqué car j’ai oublier mon mot de passe. Donc si quelqu’un peu m’indiquer comment récupérer mon mot de passe.👍👍

Search Function?: NoteLock

Very good App. I use this App a lot
However, there should be a search function in that App. In absence of this, I am wasting my time searching for a particular word which I saved it long time back.

FAQ

What does Note Lock do?

Note Lock is an application designed to protect your private notes, ideas, and journals with advanced security features. It allows you to store and manage unlimited secret collections and notes, separate from your device's default note-taking apps.

What are the key security features of Note Lock?

Note Lock offers multiple layers of security including folder lock, pattern lock, and passcode options. It also features an anti-intruder system that captures photos and videos of attempted break-ins, a self-destruction option for data erasure after multiple incorrect passcode attempts, and a discreet app name.

How much does Note Lock cost?

The application is available for free with in-app purchases. While the core functionality is accessible, certain advanced features like the full version of Lock Square Technology and unlimited note additions may require purchase.

Can I back up my notes in Note Lock?

Yes, Note Lock provides a backup feature to safeguard your information. You can back up your data to use in case your device is ever replaced, lost, or damaged, and you can also back up your passcode to your email for recovery.

What kind of content can I store in Note Lock?

You can store a wide variety of content, including lecture notes, business notes, secret ideas or information, private journals with pictures and descriptions, class lectures, love letters, and personal diaries. The app supports adding text, pictures, stickers, and sticky notes.
