Keystone Heroes does not:
- have any kind of ads. Neither now, nor in the future.
- track you in any considerable manner. The hosting service - Vercel - like any service of this category I'm aware of, collects access metrics, including, but possibly not limited to timestamp, IP address, url and browser user agent.
Keystone Heroes does:
- collect error reports through Sentry, both client and server side. These include IP address, timestamp, url and possibly the most recent actions taken by the user before the error occured. This data is automatically deleted after fourteen days and is exclusively used to detect and fix bugs.
Keystone Heroes is not a data broker.
