So this is a lie ?

This appears to be some sort of metrics functionality. Don’t think there is any bad faith.
I’d recommend nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg fix this.
The public key seems to be used for certain personalization, so it makes sense they might store that for debugging, but still a privacy risk.
They could rework their debugging system to integrate tracing and logging to identify specific issues, without storing search queries or pubkeys. And limit retention to a few days, and only when necessary (query error or high latency).

So this is a lie ?

Data not collected by the app, but perhaps user activity is logged on their caching server, since the app doesn't work without it.
It's essentially a platform.
How that works? How does an app earns that legend?
Self-reported information. App Review does some checks I think.
I would expect diagnostics to be listed.
So... Wen primal devs gonna make this right?
