The chart never changes.
You do.
Everything else here is fixed. Your birth chart said the same thing last year and will say the same thing in ten, which is the honest reason most astrology apps invent a new horoscope every morning. This is the part that is allowed to grow instead: what you asked, when you asked it, and what was true at the time.
This is stored on this device and nowhere else. No account, no sync, no server copy. Nobody can read it, and nothing here has ever been uploaded. The cost is real and worth saying plainly: clear this browser and the record goes with it. So take a copy when it starts to matter to you.
What is true today?
One or two lines is plenty. What you are carrying, what changed, what you noticed. In a year these are worth more than any reading on this site, because they are the only part of it that could not have been computed.
Nothing here yet
This fills itself as you go. Questions you put to the mirrors are kept here automatically, and anything you write above joins them. Come back at your lunar return and there will be something to compare against.
