    I don’t disagree with owning your hardware. I’m saying that a regulatory body can pose rules on where critical software can run. Part of this is data exposure: A banking app running in a tampered environment makes some malwares possible, which is the side you want an “I know what I’m doing”-button for. But it also creates risk for the bank. In letting you look into network-traffic and memory-dumps, you may discover ways to manipulate an unrooted instance or the backend server. This is security through obscurity and I’d much rather have everything open-source, but it’s what we’re dealing with.

    On the other hand, the bank promises to cover damages, whenever they do mess up. You could give them an easy excuse by taking on that responsibility. But regulations don’t allow that, much like they don’t allow you to do your own high-voltage, high-current electricity. And frown upon you breaking load-bearing walls in a housing complex to have a more open kitchen. There is a line where “let me do what I want” becomes anarchy.

    Now bringing DRM into this, misses the point. There is telemetry in these apps. But there is no piracy or copyright infringement to be had. The bank doesn’t fear you giving yourself a million dollars by changing your balance in memory. It’s all about responsibility in case something goes south. They would love to shift it all onto you, but they’re not allowed to do that. Attestation was never about protecting you, it’s about protecting them from being blamed.

    There is a bunch of parties making guarantees and complying with rulesets. Domino-ing all of them would make you extremely vulnerable. Which is why I opted for “tamper-proof containers running in a unproven host”, rather than signing an unlimited waiver.

    Well the idea of having attestation isn’t the problem. The problem is that apps requiring attestation (banks, insurance providers, ID-systems) use the most convenient solution. Slapping on Googles prebuild attestation. Graphene for example, provides alternative attestation for their OS and offers docs for anyone to implement a more fitting set of checks.

    There are two approaches here: If you’re upset that your hacked-to-bits, rooted, unlocked and/or unencrypted device is failing checks: I’d say, tough luck. Until we can create provably untampered app-containers, that level of access genuinely breaks TOS on apps and regulations on handling personal data. Breaking those checks is then breaking those compliances in an unsafe way.

    If you believe your setup is actually secure and compliant, just not in a way the allmighty Google intended: Try and get an attestation module for your setup. Fight for these apps to accept non-Google attestation and fight for devices that don’t artificially limit what can pass as secure.


  • I feel there are plenty of local activist/independent servers all over the EU. As long as you mind the encryption/anonymization, you can even round-robin them. Having a central EU authority is better than Google/Cloudflare and should be safe, if the implementation is sound. But there is a lot of room to meddle.



  • Hey there, for starters A-GPS, stun, secure DNS, and several other preconfigured servers default to Google. Some of these can be changed with ADB. Check out a guide on de-googleing LineageOS for a more complete list. It’s not AOSP, but close enough. There are also Google servers configured in the sources. How valuable those connections are, depends on your threat-model. If you’d like a paranoid GSI, check out LeOS. It’s probably the most complete treble-compatible option. AOSP by default, isn’t very private.



  • Depends on how far you want to go. From what I’ve been able to tell, they pedel a lot of flashy metrics and still had a bunch of google calls. Some of which you can manually remove, same as LOS. I would avoid buying into their cloud and keeping an eye on things yourself, if you want to install it. I saw them rebrand a bunch of OSS tooling as their own products back then. Don’t know if things changed since then, but I don’t trust the marketing.










  • Like others said, banking needs licensing and licensing costs money. If you already have a bank account, you already trust one party. Ask them if they roll their own app-payment or are already partnered with a service. That way, you can avoid google/Apple and minimize spreading the trust to other parties. My bank cooperates with Fidesmo, for example. Fidesmo then sells wearables with nfc-pay.
