The Notebook Commitment

First published July 16, 2026. Amended only in writing, here, with the date of the change.

Your notebook is your own record: dated notes and dated appraisal snapshots, written by you, on the companies you study. This page states plainly what happens to it.

What is stored

The text of your notes; and for each snapshot, the price you typed, the dial settings you chose, the sentences the page showed you for them, the day's bond yield, and the filing vintage the record ran through. Nothing else. Nothing is captured automatically; every entry is your own act.

Who can technically reach it

Your rows are locked to your account at the database itself, not merely in the application. But we will not pretend to more than that: the database administrator role can reach any row, as it can at every hosted service you have ever used, and the platform's backups retain data for their retention window. A promise of absolute technical impossibility would be false, so we do not make it.

What we commit never to do

We will never read a notebook. We will never query, aggregate, count, rank, or mine notebooks, not even anonymized ("most-noted companies" will never exist here). We will never use a notebook to train anything, sell anything, or decide anything. There is no analytics code on the notebook, and no code path in the product that reads notebooks across users.

The standing proof

This publication's code is public. Anyone may verify that the notebook's tables deny access at the database except to their owner, that snapshots cannot be edited even by their owner, and that no aggregation path exists. The commitment is not a policy we ask you to trust; it is an architecture you can read.

Your record leaves with you

The export is free, complete, and will never sit behind a payment: every note and snapshot, dated, in a plain file you can read in any editor decades from now. Delete means delete.

If this commitment ever changes, the change will be written here, dated, before it takes effect.
