What is ShardNote?
ShardNote is a secure communication platform designed for those who put privacy first. It allows you to create messages and share temporary files that are technically impossible for anyone to read except the intended recipient.
How does it protect your data?
Unlike standard cloud storage or messaging services, ShardNote uses a Zero-Knowledge architecture combined with End-to-End Encryption (E2EE).
- Client-Side Encryption: Your data is encrypted directly in your browser using the AES-GCM 256-bit algorithm (military grade).
- The Key is Yours: The decryption key is generated locally and included in the URL after the
# symbol. Browsers never send this part of the URL to our server.
- Inaccessibility: If a hacker (or even ourselves) were to access our database, they would only see random strings of text and indecipherable files. Without your secret key, the data is useless.
Self-Destruction and Control
Total control remains in your hands. You can decide the lifespan of each note:
- Single Opening: By default, the note is permanently deleted from our systems as soon as it is read for the first time.
- Time-To-Live (TTL): You can set a timer (from 10 minutes to 7 days). When the time expires, the data is automatically deleted.
- Extra Protection: You can add an optional password for an additional layer of security.
Why use ShardNote?
ShardNote is ideal for sharing sensitive information such as credentials, private documents, API keys, or simple confidential messages that should not leave permanent traces on the internet.
