There is not much of a privacy policy for Glyphus because there is not much private information. The app does not collect personal information from you, like an email address, phone number, IP address or any a/v media (i.e., photo, audio, video). There is only a set of already created images that everyone chooses from but users cannot and do not create their own images nor can they send anything else.

In order for the system to function properly, each user creates their own unique ID string of characters. This is your username. Your username is usually viewable on the top part of your screen and is necessary in order for you to send and receive images from others.

No one can search for or look up your username. It is not publicly available. You would need to tell someone your username for them to add it to their contact list of people they can send and receive images to and from. Likewise, you will need to also enter their username in order to send and receive images to and from them. If just one person does it and not the other, no images will be received. Users also have the ability to delete a username from their contact list.

Images can be deleted or not. Nonetheless, only (up to) the last 10 received images can be viewed at anytime.
