Field notes
The listed views include weekly volume by sport, aerobic efficiency, intensity distribution, personal records, and a calendar with weekly totals and rest days. The page says data is stored separately by browser and can be moved with an exported backup; it also cautions that Safari may remove site data after seven days unless the site is installed. It says Garmin syncing is intentionally absent because it would require a server and account.
