Your swim log
Every swim you have logged, with the totals. This lives on this device and nowhere else — there is no account, nothing is uploaded, and I cannot see any of it.
How to add one
Every beach, river, lake and waterfall page has a Log a swim here button beside the save button. It fills in today and the place; how long and how cold are yours to add if you want them.
The temperature box is left empty on purpose. The figure the page shows is modelled for open water some way out, and writing it into your own record would turn somebody else’s estimate into your measurement — so the log only ever holds what you typed.
Keeping it safe
Because it is on this device, it goes if the device does, or if you clear the browser’s data for this site. Use Download as a spreadsheet now and then; the file is built in the browser and is not sent anywhere either.
