Privacy

The short version: what you type into the app never leaves your device, because there is nowhere for it to go.

The app

• Nothing you type is sent anywhere. Your tests, sessions and weigh-ins are saved in your own browser and read by nobody else.
• There is no account. No name, no password, no profile.
• There is no analytics inside the app. Nothing watches what you open or what you log.
• Your license key is stored on your device too, so you aren't asked for it again. Clearing your browser data removes it, along with your log.
• Printing happens on your device. Nothing is uploaded to make the printout.

Buying it

The checkout is run by Lemon Squeezy, the merchant of record. They take the payment, handle sales tax and send the receipt. Your card details go to them and are never seen here. What comes back is an order record: the email you bought with, the country for tax, and the license key.

That email is used for the receipt, for sending the link again if you lose it, and for telling you if something in the app materially changes. It is not sold, rented or handed to anybody else.

Your choices

• Ask what is held about you, and it will be sent to you.
• Ask for the order record to be deleted, and it will be, apart from what tax law requires to be kept.
• Ask to be taken off the email list, and you are off it.
