How CuppaTA treats your information
Pilot version, November 2026.
What we store
- About you: your first name, email address, timezone and briefing preferences. If you chose a password it is stored hashed by our sign-in provider; if you sign in with Google or Microsoft we receive your email address from them and nothing else.
- Your plan: your timetable, term dates, duties and events, lesson titles, tests, homework and tasks, the check-ins you type or dictate (as text), and the briefings we have sent you.
- What we never store: pupil names, marks, seating plans, class lists or anything about an individual pupil. There is no place in CuppaTA to put them. Anything in your check-in that looks like a person's name is removed before it is saved.
Why we hold it
To run the planner you signed up for: show your day, send your briefing and replan when you check in. We don't sell it, share it for advertising, or use it for anything else.
Documents you upload
A timetable, scheme of work or school calendar is read once to build your plan. The file itself is not kept; we keep its name and the plan details read from it. Please don't upload class lists, markbooks or anything with pupils' names.
Voice
When you tap the mug, your phone sends what you say straight to Speechmatics (processed in the EU), which writes it down as you speak. The audio doesn't pass through CuppaTA and we never store it. Anything that looks like a name is removed from the text before it is saved or read by anything else.
AI
Two jobs use an AI model from Anthropic: reading a document you've uploaded, and turning your check-in into proposed changes to your plan. For a check-in the model sees your plan (lesson titles, class names, dates) and your words with names removed. For a document it sees the document as you uploaded it, which is why we ask you not to upload anything with pupils' names; it is told not to record any person's name from it. It proposes; you approve. Anthropic's API does not train on this data. Your morning briefing is put together by fixed rules, with no AI involved.
Who else handles it
- Supabase (Ireland): the database and sign-in.
- Vercel (Dublin): runs the app.
- Resend: delivers email from hello@cuppata.com.
- Anthropic: the AI model, for the two jobs above.
- Speechmatics (EU): turns speech into text.
- Google or Microsoft: only if you choose to sign in with them.
Resend and Anthropic are American companies, so emails and AI requests may be processed in the United States.
How long we keep it
Until you delete it. Deleting your account removes your plan, check-ins and briefings from our database straight away.
Your choices
- See it or take it with you: Settings → Download everything gives you one file with all of it.
- Correct it: everything in your plan can be edited in the app; your name and email preferences are in Settings.
- Delete it: Settings → Delete your account. It is immediate and permanent.
- Stop the emails or the calendar feed: both are in Settings, and you can make a new calendar link at any time.
Who we are
CuppaTA is made by one teacher on the Isle of Man. Questions and worries to hello@cuppata.com; a person reads it. If you're unhappy with how we've handled your information you can also complain to the Isle of Man Information Commissioner (inforights.im).
