Nothing is collected. Here is the detail
The short version: your inventory lives on your computer and is never sent anywhere. The long version is worth reading anyway, because two things do use the network.
01 What is collected
Nothing. No telemetry, no usage analytics, no crash reporting service, no account, no registration and no phone-home. There is no server to collect anything with.
That also means nobody can see whether you use the application at all — which is the point of buying software once instead of renting it.
02 The update check
On startup the application asks the public repository whether a newer release exists. It is an anonymous, read-only request; like any web server, GitHub sees the request and your IP address. Nothing about you or your data is sent.
03 The AI assistant, if you enable it
The assistant is off until you configure a provider. Once you do, a question sends the question, the conversation so far and the inventory rows needed to answer it — to the provider whose key you entered, under your agreement with them.
Your provider key is encrypted on disk with AES-256-GCM, and the encryption key is stored outside the database, so a backup you hand to support carries no usable credential.
04 Where your data is
In %APPDATA%\BasicInventory: the database, a rotated local error log, and the key that encrypts your AI credential. Backups go wherever you point them — including a synced folder, which then means your data also lives with that provider. Your choice, worth being aware of.
Buy it once. Use it for as long as it is useful.
The price rises every five licences sold and never comes back down. Whatever you pay today is what this copy cost, for good.
