Snow10 ☃

+

Snow10 is a simple web app for converting text to whitespace characters, which can be hidden in normal messages.

+

It is inspired by the original program published in ~1998.

+

Do not use alongside languages/emoji that use zero-width characters. Sorry, it's the way it works.

+ 
+	Threat model: person visually looking at message threads in an app such as Twitter, Matrix, Signal, documents, etc. E.g. abusive family
+
+	Encrypt the secret message using something like age or keybase before using if encryption is needed.
+
+	Will not resist forensic analysis.
+
+	Privacy: This works client-side and does not log any messages.
