TokenTank v0.3.0 - Windows

First public release. TokenTank is the fuel gauge for your AI tools — a system-tray app that shows how much of your usage quota is left and when it refills, instead of only what you spent.

Features

• Tray tank icon that drains as you consume your 5-hour session or weekly quota (whichever is tighter). White = plenty, amber = under half, vermillion = under a quarter. Hover for percentages, burn rate, and reset countdowns.
• E-to-F fuel dial in the popover with a live countdown to your next session reset, plus a horizontal weekly tank with its refill time.
• Session-block modelling that mirrors how Claude's 5-hour windows actually behave, and a weekly window anchored to your real reset time.
• 60-second calibration wizard — pick your plan and copy three numbers from the Claude app's Settings → Usage panel; ceilings compute from your real spend. Re-calibrates automatically whenever you actually hit a limit.
• Burn rate, today, last-30-days, and plan multiple at a glance.

Privacy

Everything runs locally. TokenTank reads your local transcript files and nothing else — no account access, no network calls, no telemetry. The source is small enough to audit before you run it.
