"I built Open Period because I watched the maths up close: the pile that never shrinks, the evenings that do, and the feedback cut first every time. I didn't want a tool that marked for teachers. I wanted one that gave the boring half back and left the judgement where it belongs. With you."
Scott, the maker · English teacher in training, ACU
01 · The one-page summary
What it is, and how it treats student data.
In plain language an executive can read in two minutes, before they ask a single question.
What it is
An Australian teaching-workload tool that drafts feedback, marking, and parent emails. Built by a teacher, for teachers.
Who reviews the output
The teacher, always. Every result is a starting draft, not a finished judgement. Nothing reaches a student or parent unreviewed.
Student names & IDs
Stripped from text before it reaches the AI: once in the app, and again by a server-side backstop. The number removed is shown on every result.
What the AI is
Anthropic's Claude, accessed by API. Under Anthropic's commercial terms, API inputs and outputs are not used to train their models.
What we store
Only usage counts and the sign-up email. We do not store student drafts, generated feedback, or prompts.
Where it's processed
De-identified text is processed overseas (US) by Anthropic. We disclose this overseas processing to teachers in-product and on our public pages.
Selling / sharing
Never. Data is disclosed only to the processors needed to run the service: Anthropic (AI) and Formspree (sign-up forms only).
Consent & policy
The teacher and school remain responsible for consent and for following the school system's policies on AI use and de-identification.
We don't overclaim. Automated stripping is not infallible. Free text can contain identifying detail no automated pass catches, so teacher de-identification stays the primary safeguard. Estimated grades or bands are for drafting and practice only: not official, not a NESA determination, not a prediction of any exam result.
02 · The data flow
How a student draft moves through Open Period.
The exact path a piece of student work takes, and the two points where identifying details are removed.
1
Teacher submits a draft
The teacher pastes or uploads student work in the app. Teachers are instructed never to include identifying details.
↓
2
In-app de-identification
Names and identifiers are detected and replaced before the text leaves the browser session.
↓
3
Server-side backstop
A second pass strips identifiers again on the server. The count of removals is shown to the teacher on every output.
↓
4
AI processing: Anthropic Claude (US)
The de-identified text is processed to produce a draft. Inputs and outputs are not used to train the model.
↓
5
Result returned to the teacher
The teacher reviews, edits, and decides what to use. The draft and the feedback are not stored on Open Period's servers.

Prompt content
One honest exception: photographed handwriting. When a teacher photographs handwritten work, the image is sent to the AI to transcribe it, so a name written on the page is visible to the AI during that step. The name is replaced with "Student A" in the transcription, and teachers are instructed to keep names on a cover sheet or crop them out before photographing.
03 · Bring this to your exec
A proposal, a principal email, a parent statement.
Three things you can copy with one click, fill the blanks, and send. Let the facts above do the explaining.
A. One-screen proposal
Drop this in a doc or an email body. It answers the data question before it's asked.
PROPOSAL: Trial of Open Period (teaching-workload tool)
What it is: An Australian AI tool that drafts feedback, marking, and parent
emails. The teacher reviews and decides on every output.
Why: Marking and feedback are the largest time cost in our faculty.
This drafts the first version so we spend our time on judgement,
not typing.
Data handling: Student names and identifiers are stripped before any text
reaches the AI (in-app + a server-side backstop, with the
removal count shown). No student drafts or feedback are stored.
The AI provider does not use our inputs to train its models.
Full data-flow attached.
Our duties: We continue to de-identify work and follow Department and school
AI policy. Estimated grades and bands are for drafting only.
Scope: [ ___ teachers ] · [ Year ___ / faculty ___ ] · the free trial
period when Open Period opens to founding teachers.
Cost: Free for founding teachers when it opens. Two weeks free, no
card, no payment details required.
I'm asking for: Approval to run a de-identified trial when access opens, then a
five-minute review of whether it saved us time.
B. Ready-to-send email to your principal / head teacher
Paste it, swap the brackets, and send. The pack above is the attachment.
Subject: Approval to trial a marking/feedback tool (de-identified) when it opens
Hi [Name],
I'd like approval to trial a tool called Open Period with [my classes / our
faculty] when it opens to founding teachers. It drafts feedback, marking and
parent emails; I review and decide on everything it produces.
I know the first question is data. In short: student names and identifiers are
removed before any text reaches the AI: once in the app and again on the
server, and the number removed is shown to me each time. Student drafts and
feedback aren't stored, and the AI provider doesn't use our inputs to train its
models. I've attached a one-page summary and the full data flow.
Founding teachers get free access when it opens: two weeks free, no card. And
I'll keep de-identifying work and following our AI policy throughout. After the
trial we can take five minutes to decide whether it actually saved time.
Happy to walk you through the attached pack whenever suits.
Thanks,
[Your name]
C. Parent-facing transparency statement
Defensible language for families. It reframes the tool from a secret shortcut to a professional one, with the teacher in control.
How we use AI to support feedback
Some of the written feedback your child receives may be drafted with the help of
an AI tool, which the teacher then reviews, edits and approves before it is
shared. The teacher makes every judgement about your child's learning. The tool
drafts, the teacher decides.
To protect privacy, student names and identifying details are removed before any
work is processed by the tool, and student work is not used to train any AI
system. Our use of these tools follows Department and school policy.
If you have any questions about how we use these tools, please contact
[teacher / school contact].
Use as a starting point. Adapt the bracketed details to your school's voice, and check each piece against your school's communications and AI-use policy before sending.
Built for your school's AI policy
The tool that can't break your data policy.
Student data never leaves your computer in identifiable form. Names and identifiers are stripped before anything reaches the AI, twice.
Made for the Australian Framework for Generative AI in Schools: AI drafts, a human decides. You're the assessing teacher, start to finish.
You approve every word before it goes anywhere near a student, parent or report.
NSW DoE tells staff not to put student work into free cloud AI. Open Period is built so it can't. It's the safe answer, not a quiet workaround.
"The privacy is in the architecture, not just the promise. Identifiers are stripped before the text leaves the browser, then stripped again on the server, with the count shown to you."
Alignment with the framework, not endorsement by it. Independent of NESA and the NSW DoE.

Fair questions
The exec's questions, answered straight.
Is student data sent to the AI?
Only after it's de-identified. Student names and identifiers are stripped before any text reaches the AI, once in the app and then again by a server-side backstop, and the number removed is shown to the teacher on every result. We're honest about one exception. When handwriting is photographed, the image is sent to the AI to transcribe it, so a name on the page is visible during that step; the name is replaced with "Student A" in the transcription, and teachers are told to crop or cover names first. Automated stripping isn't infallible, so teacher de-identification stays the primary safeguard.
Is any of it stored?
No student drafts, no generated feedback, and no prompt content are stored on our servers. We keep only usage counts and the email you give us to join the founding list. The draft and the feedback live in your browser session and are not retained by Open Period.
Is it NESA or NSW DoE approved?
No. Open Period is an independent product, not affiliated with, endorsed by, or approved by NESA, the NSW Department of Education, or the NSW Government. It is built for the Australian Framework for Generative AI in Schools, where AI drafts and a human decides, but alignment with a framework is not endorsement by it. Always follow your own school system's AI policy.
Can I really just send this to my principal?
Yes. Copy the one-screen proposal and the ready-to-send principal email from the exec kit above, fill in the brackets, and attach the data-flow summary on this page. There's a parent-facing statement too. They're written to answer the data question before it's asked, which is the whole point of the kit.
What does it cost?
The kit on this page is free and needs no sign-up. For Open Period itself, you're joining the founding list right now. Leave your email and you'll be first in when we open, with free founding access for early teachers: two weeks free, no card, nothing recurring to join.
