Kompakt technical questions

[hiItsMe]

hi @urszula - thanks for your answers - i’m quoting here from your other post…

Mudita Kompakt features Offline+ mode , which is a hardware-level switch cutting power to the GSM modem and microphones. It also disables the camera, Wi-Fi, and Bluetooth at the software level. This is designed for users who want a quick, physical way to ensure that radios and microphones are off.
If you’re looking for deeper architectural protections such as baseband/memory isolation, that’s not the focus of this device. Mudita Kompakt uses a MediaTek MT6761 chipset, which means the modem/baseband firmware is closely integrated with the SoC. IOMMU support is not a universal feature in all mobile phones, it’s generally found in high-end or specialized security devices.
I can check with our dev & hardware teams for a definitive answer on whether the modem is isolated from the main user-space or RAM. However, at present, we don’t market Kompakt as offering that specific level of hardware isolation.
As for Sentry, it’s an open-source error tracking tool. In our case, any data (BUT NO IP DATA is collected) collected flows directly to us, is not shared with anyone, and does not leave our systems. It’s used solely to help us improve performance and fix potential bugs.
Our goal with Kompakt is to provide essential functionality, physical privacy controls, and a more mindful relationship with technology, rather than targeting the high-security niche.

i had hoped that Mudita held a stronger position regarding privacy and security given the company is marketing a de-googled device - the decision to use the MediaTek MT6761 modem and apparent lack of modem isolation from user-space in combination with the forced telemetry is off-putting enough that i believe i’ll pass on this phone

“[…] as long as users don’t control what code runs on the baseband, they do not in fact have ownership of the device.”

unfortunately all cellular devices having a baseband/modem are forced to run bug-riddled, insecure, proprietary code and this is why proper isolation of the modem and baseband OS is crucial

i’m aware of the hardware switch - i was referring to a software option to disable telemetry when i mentioned a ‘switch’

regarding Sentry, i understand no PII is collected, however users must be made aware during setup of what data is collected and why and they must have the option to disable collection (most people, including myself, will be happy to send telemetry as long as they know no PII is sent)

not offering the option to disable telemetry in combination with not informing users at setup of Sentry is a decision that could come back to bite Mudita - i’m just telling you this based on what i’ve seen with other companies
