documentation
Running your own instance.
sardinetracker is meant to live on your machine, which means the parts nobody else can do for you — getting to it from outside the house, and working out what broke when it stops answering — are documented here rather than assumed.
Remote access
Reaching your own instance from outside the house — a Cloudflare Tunnel or a Tailscale VPS, with the trade-offs of each spelled out.
Troubleshooting
Symptom-first triage for a deployed instance. What to check, in what order, when the site won't load or a device stops syncing.
Using sardinetracker
The in-app help, on the web: what each view is for, what the numbers mean, and how to log a day without it becoming a chore.
