Inputs stay in this tab and are not uploaded or saved automatically. Optional aggregate usage counts and coarse processing diagnostics are sent only after consent, without input content or filenames. Clearing or closing loses inputs; save needed outputs first.
Method and limits
Name 1 to 16 counters and use +/−, the focused +/− keys or Undo. Counts range from −1e9 to 1e9, names can have 80 characters, and there are 128 undo states. CSV keeps quotes and newlines; risky ASCII formula prefixes are escaped with an apostrophe. JSON keeps the exact names. This is a local browser observation only: no hardware diagnosis and no universal accuracy. Nothing is stored, recorded or uploaded, and no private-data telemetry is sent. Stop or reset clears the session. Browser, OS or permissions may leave results UNKNOWN.
