Focus Session Totals

Totals elapsed, break and active minutes from explicit same-day session start/end minutes. Rejects overlaps and breaks longer than a session to prevent double counting. Active time is arithmetic, not evidence of attention quality or productivity. Uses only adult user-controlled facts; review the result. No external lookup, storage or sending. Uses explicitly supplied structured inputs. Server computations are transient; the standalone website computes locally in your browser. Review the output before exporting it. No persistent account records, external source retrieval, sending, transactions or paid model calls. CSV/JSON review and export are available on the standalone website. MCP requests are capped at 128 KiB and computed responses at 256 KiB; individual field and record limits also apply.
