Apple and Google both provide support for offline speech-to-text using local models. Users can configure it to be fully offline.

The Murena Voice to Text service in /e/OS sends the user's audio to OpenAI which is hidden away in their terms of service:

Voice to Text feature using Open AI

Thank you a lot for your positive and supporting comments about our new /e/OS Voice-to-text! Regarding its implementation in /e/OS, I’d like to explain a few things to explain why we have chosen an OpenAI STT API to implement it and how it’s going to evolve in the future: What we have learned from our experimentations with STT models that run locally on the smartphone for speech recognition: they work quite poorly, they make a lot of mistakes in voice recognition they are not able to mix la...

/e/OS is heavily marketed as private but in reality it has enormous privacy issues like this with their default apps and services. It's also heavily marketed as avoiding Google services but yet has privileged integration for Google services and connects to multiple by default.
/e/OS doesn't keep up with basic privacy or security patches for the OS or browser engine used not only for the default browser but also the WebView used by many apps including email clients and far more for rendering web-based content.

/e/OS is not a threat to mass surveillance but rather significantly helps with it by making exploiting devices to extract data or take remote control over them far easier. They do not keep up with basic High and Critical severity patches. All devices sold by Murena are insecure.
Even on Pixels, /e/OS is extremely far behind on providing the current High and Critical severity privacy and security patches due to being so far behind on OS updates. They mislead users by setting a fake security patch level and changing the UI to mask what's happening.
Murena is a for-profit company and /e/OS is very clearly built and managed for the benefit of Murena. Despite this, /e/OS receives a huge amount of EU government funding. If you're an EU taxpayer, your money is being used to build this extraordinarily insecure and non-private OS.
@GrapheneOS Seriously, jealous of EU funding? Please. Stop kicking down to your colleagues and start kicking up to the real competitors
@djoerd @GrapheneOS known scammers are not colleagues lmao. They’ve grifted for years and should be called out for it.
@monew @GrapheneOS I am sorry you were scammed. I can recommend a Fairphone with e/OS to prevent such events in the future. Did you know it block trackers inside Android apps and allows you to use a fake location? Pretty neat

@djoerd @monew

> Did you know it block trackers inside Android apps

All it provides is a terrible implementation of DNS-based filtering. Contrary to the false marketing, it cannot stop privacy invasive behavior by apps It blocks a small portion of client side connections to domains not used for actual functionality. Vast majority of privacy invasive behavior remains and it's trivially bypassed. RethinkDNS is a better implementation usable everywhere, but DNS-based filtering is very limited.

@djoerd @monew

> and allows you to use a fake location

This is a standard Android feature called Mock Location.

> I can recommend a Fairphone with e/OS to prevent such events in the future.

The reality is that /e/OS is an extraordinarily insecure and non-private OS being marketed as something it's not. It does not provide people with the basic Android privacy/security patches and doesn't keep the basic security model intact. Murena even sells people already end-of-life devices.

@GrapheneOS @monew Take it easy, I know all this. That's no reason to call e/OS fake, misleading and misusing EU funding. I still think e/OS is a great alternative to the Apple/Google duopoly for the average person. They're on your side. Happy to try Graphene once it runs on ethical hardware like the Fairphone.

@djoerd @monew Your claims are objectively false. /e/OS is absolutely engaging in extremely false marketing about privacy, security, updates, usability and compatibility. They've repeatedly spread misinformation about GrapheneOS and it's why we started posting about it.

/e/OS is not a safe option for anyone to use and does not offer a reasonable alternative to Apple or Google products. It is not more focused on regular people than GrapheneOS, contrary to their misleading claims about us.

@djoerd @monew /e/OS is certainly not on our side. They aren't in the same space as GrapheneOS in the first place but rather only pretend to be as part of their marketing. They've repeatedly engaged in attacks on GrapheneOS through spreading misinformation about it and making personal attacks on our team.

> Happy to try Graphene once it runs on ethical hardware like the Fairphone.

Fairphone devices do not meet our basic hardware security and update requirements. False marketing is not ethical.

@[email protected] @[email protected] Really? Now Fairphone is ALSO using false marketing? You're paranoid, mate! I used to be a happy FirefoxOS user. You cannot scare me with less-than-state-of-the-art hardware.

@djoerd @monew Fairphone has always misrepresented the level of updates and long term support provided for their hardware. They present providing an update released in 2022 in 2025 as providing 3 more years of support than OEMs which shipped it on release day. That has never made sense. Fairphone's lags far behind on providing current OS updates with full privacy/security patches, typically a year or more. They lag 1-2 months behind on providing the partial backports to older Android releases.

@djoerd @monew Fairphone is directly participating in the false marketing by Murena for /e/OS. They present it as being far more private than it is and lead people to believe it isn't going to be using Google services and giving highly privileged access to them when it does.

Making baseless personal attacks on our team claiming we're delusional, paranoid, etc. has been repeatedly done by the founder of /e/OS and Murena. You're demonstrating how their community follows this lead.

Ok, Fairphone is bad too. I am sorry I brought that up. Have a nice day, @GrapheneOS.
