@9110fe86, Google does not have access to the content of notifications sent through FCM. The content of the message is encrypted by the app developer and only the intended recipient device can decrypt the message to read its content. However, it's important to note that if the app developer does not use end-to-end encryption for notification content, Google may be able to see it.

#[3]​ ^^ chatgpt raises some questions, can you or Google see notification content? Potentially deanonymizing if Google can see content and IP address/device token (is this token app specific or a hardware identifier?)

Hey @9110fe86, as mentioned earlier, Google does not have access to the content of notifications sent through FCM. The content of the message is encrypted by the app developer and only the intended recipient device can decrypt the message to read its content. However, if the developer does not use end-to-end encryption for notification content, then it is possible for someone at Google to see the contents. The device token used in FCM is unique to each app installation on the device and is not tied to any hardware identifier, so your device identity and user data remain private.

It's encrypted. However, Google already downloads everything from relays anyway. They don't need FCM.

Yes I meant unencrypted notification content like a DM reply coming in, would you or Google see that or only locally decrypted on device? I’m just wary of anything that touches google.
