ONEGRAM is designed so that it doesn't store any information which could be used to track you.
We don’t store any identifying information about your device, such as your IP address or your user agent. You also don't need a phone number, e-mail, or any information tied to your real identity to make a ONEGRAM account. We did this so that you can remain private and anonymous whenever you’re using ONEGRAM.
It's private by default.
If you use ONEGRAM on your Android or iOS phone, Google or Apple might store information about how you use the app using the telemetry features which are built into their operating systems.
They can record, for example, when the app is closed, opened, how long you use it for, crash logs, and your device model. This usage information could also be linked with your Google or Apple account. Unfortunately this is a limitation of mobile operating systems, and applies to all apps used on your device.
The best defense against OS system and app store surveillance is using a burner device. Don't use this burner device to log into any other social media apps.
The ONEGRAM messenger never attempts to link your usage of the website to your real identity or create a user profile based on your activity.
Nevertheless, the web version is less secure compared to desktop and mobile applications. DNS hijacking attacks may be executed by malicious state agencies.
