Is self-hosted enough to avoid push notifications going through Apple and Google servers?
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don’t control.
Rules:
Be civil: we’re here to support and learn from one another. Insults won’t be tolerated. Flame wars are frowned upon.
No spam posting.
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it’s not obvious why your post topic revolves around selfhosting, please include details to make it clear.
Don’t duplicate the full text of your blog or github here. Just post the link for folks to click.
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
No trolling.

How does it handle push notifications? If they come from googles push service then they’d be exploitable as well.
Indeed - it seems that this tracking is done completely outside of the phone, asking the network where, physically, the push notification was delivered (Tower, time, and date) to locate the phone and ostensibly the owner of the phone.
