Organize Your Notes
By the end your notes will be in a shape you can still understand when you come back, and you will know where they are kept and what would delete them.

THE IDEA
Your task: tidy your notes and check where they are kept.
Diagram: a double ring. The outer ring is divided into twelve parts for the signs, the inner ring stands for the houses, and a horizontal line on the left is labelled ASC, the starting point. A concept figure with no real degrees.
When you tidy your notes, keep the dates, the bases and the doubts.
Tidying so you can come back
Records are only worth comparing if you can tell them apart. So keep three things when you tidy. First, dates: six months on, that is how you tell what you wrote then from what you changed later. Second, the basis marks: computed, traditional, or my own observation. Third, the doubts: candidates, descriptions that missed, things you have not worked out yet.
Reflection promptKeep those three and every line can be traced to its source and compared six months on — that is exactly what makes notes useful.
Reflection promptWhat the old texts say: Book I ch. 2 of Ptolemy's Tetrabiblos says one reason predictions fail is that the examples they rest on are not alike.
Cited sourceYour notes are kept on your own device, and they are still there after a membership lapses.
Where your notes are kept
Your notes, read marks and last reading position are kept on this device, together with your birth data. Delete all data in settings clears the notes and progress together, and it cannot be undone.
How this tool worksThe first three lessons are free; from lesson four on, approved lessons are member content and need a membership to open. Every lesson opens once it has been approved. When a membership lapses, member lessons lock again, and notes and progress stay on the device; notes on the locked lessons are put aside and return to the notes overview when you are a member again.
How this tool worksYour notes stay on this device, in your own keeping.
How this tool worksSo if a line matters to you for the long run, copy it into your own notes app as well.
Reflection promptOBSERVE YOUR OWN CHART
Look at my chart
One last task: tidy the notes you have made along the way.
- Add a date and a basis mark to each note.
- Keep the candidates and the mismatches; they are the most useful part.
- Copy the lines that matter into your own notes app as well.
Without a birth time, rising sign and houses stay blank.
LOOK CLOSER
A common mix-up
“The shorter the notes, the better.”
Keep the dates, bases and doubts, and a note can be traced to its source and compared later.
“My notes disappear when my membership lapses.”
A lapsed membership only locks the member lessons again; it deletes no notes, and your progress stays too. What really clears them is delete all data in settings.
CHECK YOURSELF
Now, try it yourself.
Sources and rights
- Ptolemy, Tetrabiblos, trans. F. E. Robbins (Loeb Classical Library, 1940)
Book I ch. 2 gives the disparity of the examples as one reason predictions fail, which is why this lesson says records must be distinguishable to be worth comparing. The dates, basis tags and keeping of uncertainties are this lesson's arrangement, and where notes are stored, what delete all data does, and that the first three lessons are free, approved lessons from four on need a membership, and a lapse locks them again without deleting notes, are this app's actual behaviour today.

Limits of this lesson
For prices and plans, the membership page is what counts.
Lessons not yet approved stay closed to everyone, member or not.
When a membership lapses, notes on the locked lessons drop out of the notes overview for now, but they are not deleted.
Notes live only on this device and are not backed up to a cloud or sent anywhere; copy out any line you want to keep for the long run.
The before-and-after lines are only a demonstration, not anyone's real notes.
YOUR STUDY
Write what you learned in your own words.
Write it down: the three lines from this course you most want to keep, each with a date and a basis.
Your note stays in this browser. Switching languages will not translate it.
