Your family's privacy

The short version

• No cookies, no tracking pixels, no consent banner. Nothing on your device follows you around the web.
• We never sell your family's details, and we never hand them to advertisers.
• Your child's work is used to teach and mark your child, and to report to you. It is not used to train anyone's AI.
• We never hold your passwords. Google's Firebase does, hashed, and we can't read them.
• The tutor is never told your child's name. It sees the question, the answer and its own notes.
• Ask, and we'll show you everything we hold, correct it, or delete it.

What we collect, and why

Your account

Your first name and your email address, which is your login. Your surname and cell number are optional. We use these to run your account, to send you account and billing emails, and to send you your child's reports.

Your child's profile

First name, a username and password, grade, language of instruction, and their school and province. Surname and birthday are optional. We use these to serve the right curriculum and to greet your child in the app. Everything inside Studywork is keyed on an internal ID, never on a name.

Your child's work

The answers your child gives, whether typed, spoken or photographed; their conversation with the tutor; their marks and progress; and the tutor's notes on how your child learns, such as what they struggle with and what finally clicked. This is what lets the tutor mark, guide, report to you, and make the next session fit your child. A spoken answer is turned into text as it is spoken, and the audio is not kept. A photographed answer is stored in a private store that only we can open, so the tutor can read the handwriting.

Payment

Paystack processes your payment and pays us. Your card number never reaches us. We keep Paystack's reference for your subscription and the plan you're on, and nothing else about your card.

Technical records

Our server keeps a log of what the app did, keyed by internal ID and never by name. It includes your child's answers and the mark given, so we can review a wrong mark, and the internet address of visits to our public pages, so we can stop abuse. Log lines are deleted after 90 days.

Bug reports

When your child taps Report a bug, we receive what they wrote, the screen they were on and the app's own error messages. No screenshot is taken.

Who else handles it

Five companies touch your data, each for one job. This is the whole list.

Google Cloud

Hosts Studywork and its database in Google's data centres in Iowa, in the United States. The tutor's model, Gemini, runs in Google's Belgium region through Vertex AI, where Google does not use what we send it to train its models. Google also turns your child's speech into text and the tutor's words into speech. POPIA allows data to be held abroad where the host is bound to protect it to a similar standard, and Google's terms do that.

Paystack

Takes your card details and your monthly payment. We never see the card.

Gmail

Sends our emails from info@zandeo-ai.com. There is no open tracking and no click tracking in anything we send.

Claude

Claude, made by Anthropic, is the AI we build Studywork with. It writes and checks the code, and it runs our daily checks on the live system under Hex's or Hannes's login. When it does, the records it reads pass through Anthropic's servers in the United States, under terms that do not use what it reads to train Anthropic's models. Claude never speaks to your child: the tutor in the app is Gemini.

Meta, only if you came from one of our adverts

If you tapped a Studywork advert on Facebook or Instagram, Meta puts an ID for that click in the link. Our server then tells Meta when that visit tapped Start on the Try Studywork page, reached the first question, reached Create account, or signed up, so we can see which adverts work. Meta receives the click ID, your internet address, your browser type and the page address. It never receives your name, your email, or anything about your child, and nothing is placed on your device. If you didn't arrive from an advert, Meta hears nothing from us.

We use no analytics service, no advertising network, and nobody else.

Your rights, and how long we keep things

You can ask to see everything we hold about your family, to correct it, to delete it, or to object to how we use it. Message us at info@zandeo-ai.com and it is done; no forms. Deleting an account deletes the children's profiles, their work and the tutor's notes. We keep invoices for as long as tax law requires.

We keep your account while it is open. If you cancel, we keep it so your child can pick up where they left off if you come back. Ask, and we delete it.

If you feel we have not handled your information properly, you can complain to the Information Regulator of South Africa at inforegulator.org.za. But we would rather hear from you first.
