Your device and Android version
Both are on the System tab in the app. Manufacturer skins restrict different kernel interfaces, so this often explains a missing value on its own.
Support
Something looks wrong? Tell me.
cpux is maintained by one person, so support is a direct email rather than a ticket system. I read everything that comes in and reply as quickly as I can manage.

Before you write
What to include
Device readings vary enormously between manufacturers. These four details let me reproduce almost any report without a back-and-forth.
Which tab and which row
For example "CPU tab, cache row" or "Battery tab, cycle count". The more specific, the faster it gets fixed.
What you expected to see
If another tool reports a different value, tell me which tool and what it said — that's often the fastest route to the real cause.
A screenshot, if you can
cpux screens contain no personal information, so a screenshot is safe to send. Attach it and I'll usually spot the issue immediately.
Common issues
Answers to the usual questions
A value shows a dash on my device
That means Android or your manufacturer refused the app access to the interface that value comes from. It is not a bug in the reading — cpux deliberately shows a dash rather than inventing a number. It's still worth reporting, because sometimes another readable source exists for the same value.
CPU usage is labelled "estimate"
Some devices deny apps access to
/proc/stat. On those, utilisation is inferred from core clock frequencies rather than measured, and cpux labels it as an estimate wherever it appears.The chipset name doesn't match my phone
Marketing names are resolved from the identifiers your device exposes, and some manufacturers ship several distinct chips under one platform identifier. The raw identifiers are always shown alongside the resolved name — send me those and I can correct the mapping.
My Wi-Fi network name isn't shown
Reading it would require location permission, which cpux does not request. That reading is intentionally left out.
How do I delete my data?
There is nothing to delete. cpux stores exactly one value on your device — the version of the terms you accepted — and it is removed when you uninstall the app. Nothing is ever sent anywhere, so there is no server-side copy of anything.
Can I request a new reading or a new tab?
Yes, please do. If the platform exposes it without requiring an invasive permission, it's a fair candidate.
