The short version
There is no account, no database and no tracking. Your name, date, time and place of birth are used to compute your chart and are not written to disk. Close the tab and nothing about you remains.
What leaves your browser
To read your details out of a sentence, the message you type is sent to OpenAI’s API. To draw your chart, the date, time and the coordinates of the place you picked are sent to our own server. Neither of those is stored by us afterwards.
What we log
Our server keeps plain-text operational logs — which endpoint was called, whether it succeeded, how long it took, and a one-way hash of the IP address so we can apply rate limits. Names, dates, times and places are redacted before anything is written. The hash uses a key that is regenerated whenever the server restarts, so log entries cannot be linked back to a person or joined across restarts.
The chart image
Your chart is delivered as an image that contains only the charts themselves — no name, date, place or coordinates appear anywhere in it. That is deliberate: it means the image is safe to save and share without giving away your birth details.
Your session
Your conversation is held in your browser for as long as the tab is open, so a refresh does not lose your chart. It is cleared when you close the tab, and never sent anywhere beyond the calls described above.
