#DHSeaDev — Chrome MV3 — Popup Extension
Dota Companion
Your private Dota 2 improvement dashboard — improvement streaks, goals measured against your own baseline, hero stats, and private player notes. Local-first: no account, no API key.
Field Guide
Dota Companion is built for the climb between matches, not the match itself. Its improvement streak counts consecutive recent games that beat your own GPM baseline — so the number tracks getting better, not just showing up. Set a goal against a real metric (GPM, KDA, last hits, or win rate) and the progress bar measures it against your current twenty-game average. The player-notes tab is the piece you cannot get from a stats site: tag and rate the people you run into — smurf, thrower, playmaker — and it stays, privately, only on your device. Enable “Expose Public Match Data” in Dota 2 settings so your matches are visible to the public OpenDota API the extension reads from.
What it does
Improvement Streak
Counts consecutive recent games that beat your own GPM baseline. The streak measures progress, not attendance.

Player Notes
Tag and rate anyone you run into — smurf, thrower, playmaker. Private, stored only on your device.
Recent Form
Win/loss streak, last-ten results, and most-played heroes with per-hero win rate — one toolbar click.

Privacy Policy
Your notes, goals, and cached matches are stored locally in your browser and never leave your device. No accounts, no telemetry, no analytics. The extension makes one kind of network request: fetching public Dota 2 match data from the OpenDota API for the account ID you enter.
