Your GPX data and photos are uploaded to our server to create the postcard, and immediately deleted afterward.
Your postcard is available at the download link for around 60 minutes after it's created. After that, we delete it.
The title of your activity is recorded, just so we know how many people are using this tool. Basically, every time someone creates a postcard, we get an email saying: "Hey, someone created a postcard "Morning Run"". That's it - nothing else.
Apart from this we don't store or sell or do anything else with your data.
