// Q: Why does Next.js need a project ID? Why is it looking at my git remote?
|
|
// A:
|
|
// Next.js' telemetry is and always will be completely anonymous. Because of
|
|
// this, we need a way to differentiate different projects to track feature
|
|
// usage accurately. For example, to prevent a feature from appearing to be
|
|
// constantly `used` and then `unused` when switching between local projects.
|
|
// To reiterate,
|
|
// we **never** can read your actual git remote. The value is hashed one-way
|
|
// with random salt data, making it impossible for us to reverse or try to
|
|
// guess the remote by re-computing hashes.
