LineageOS Statistics Backend

Data Collected

Devices check in (roughly) daily with the following data:

• Device ID: The sha256 of Settings.Secure.ANDROID_ID. This ID is reset every time the device is wiped.
• Device model, taken from ro.cm.device.
• Device version, taken from ro.cm.version. For Lineage builds, this is in the format VERSION-DATE-TYPE-MODEL.
• Device country, as reported by the SIM card.
• Device carrier, as reported by the SIM card.
• Device carrier ID, as reported by the SIM card.

Additionally, we record the following:

• Current time the request was made.

Limitations

• Devices do not retry when a check in fails, it is assumed they will check in the next day. As such, device counts for a given day may be lower than the actual number of devices available.
• Devices lose their ANDROID_ID when they're either wiped. As such, device counts may be high if a large number of wipes have occured during the period (ie, during new release times).
• Devices without sim cards do not report their country, carrier, or carrier ID.

All stats are displayed, you'll want to drop old data if that's a thing you care about. We keep 90 days. Only the last checkin for each device is kept.
