The 90-Day Run Tracker

Daily habit tracker for the 90-Day Run (Sep 27 – Dec 25, 2026): workout, daily spend, meal plan, code commits, job applications, reading, HYSA deposits, weigh-ins and milestones.

Static site — a single index.html, no build step.

Deploy on Vercel

1. Push this repo to GitHub.
2. In Vercel: Add New → Project → Import this repo.
3. Framework preset: Other. Leave build command and output directory empty.
4. Deploy.

Data

Progress is saved in the browser's localStorage first, so it always works offline. Click Sync in the header to also back it up server-side and share it across devices/browsers:

1. In the Vercel dashboard, open this project → Storage → add an Upstash Redis database (Marketplace, free tier). This auto-injects KV_REST_API_URL / KV_REST_API_TOKEN-style env vars the @upstash/redis client reads via Redis.fromEnv().
2. Redeploy so the new env vars are picked up.
3. Click Sync on the site, enter (or generate) a short code, and enter that same code on any other device to pull the same run.

The sync code is a lightweight passcode, not real authentication — anyone with the exact code can read/write that run's data. Fine for personal use; don't reuse a guessable code for anything sensitive.
