Trail Bubble is designed to be an anonymous app — no accounts, no PII collected during normal use. This contact form is the one exception. Your email address is stored only to reply to your message. It is not shared with third parties, used for marketing, or retained longer than needed. If you would like your email and message deleted after we have replied, just say so in your message and we will remove the record. You can also read more about how we handle data.
