Privacy Policy

Last updated 24 August 2026

Classical Calendars turns homeschool assignment documents into weekly checklists. This policy describes what the service stores, who it is shared with, and how to get rid of it.

What we store

Your account. The name, email address and profile picture your Google account provides when you sign in, plus a Google account identifier.
What you enter. The names you give your children, and the order you arrange subjects in.
Documents you choose. The text of each assignment document you add, whether picked from Google Drive, pasted, or uploaded. We keep the text so weeks can be generated from it later without re-reading the original.
Generated schedules and your progress. The weekly charts produced from your documents, and which items you have ticked off.
Usage records. The number of weeks you generate and their processing cost, so limits can be applied fairly.

We do not use cookies for advertising or analytics. The only cookie is the one that keeps you signed in.

Google Drive access

Classical Calendars requests the drive.file permission. This grants access only to the specific files you select in Google's own file chooser. The service cannot see, list or open anything else in your Google Drive, and access does not extend to files you have not chosen.

Chosen documents are read once to extract their text. We do not modify, move, share or delete anything in your Drive. Classical Calendars' use of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements.

Who else sees your data

Anthropic. The text of a week is sent to Anthropic's Claude API to be condensed into a checklist. Anthropic processes it to return that result. It is not used to train models.
Our hosting and database provider, which stores the data on our behalf.

We do not sell your data, and we do not share it with anyone else.

About children

Accounts belong to parents and guardians. Children do not sign in and have no accounts. The only information about a child is the name you type and the schoolwork you choose to add — please use a first name or nickname rather than a full legal name.

Keeping and deleting data

Your data is kept while your account exists. Deleting a child removes their documents, schedules and progress immediately. Deleting your account removes everything associated with it, permanently and without a recovery period. You can also revoke this app's Drive access at any time from your Google account permissions.
