Clareza is used by families, and that includes children. We collect the minimum needed to run an adaptive course and produce your records, we show no ads, we sell no data, and the parent controls every child account, including deleting it.
Children never sign themselves up. A child's account can only be created by the parent who runs the family's Clareza account, from inside that account, creating it is how the parent gives consent for the child's use of the service. A child's sign-in does not need to be a real email address, and we encourage using one that isn't (like [email protected]).
From a child we collect: the first name and sign-in the parent chose, the child's learning-preference answers, and their learning activity, answers given, time spent, hints used, and the mastery scores computed from them. That's what powers the adaptive course and your transcript. We collect nothing else from children: no location, no contacts, no photos, no browsing outside the app.
Learning support settings (the boxes you tick under "What helps your child learn?") stay within your family: they are never shared with analytics, they are included in your data export, and they are deleted with your child's account. We never ask for or store a diagnosis.
Parents can see everything their child has done, change the child's password, and delete the child's account and its data by contacting us (a self-serve delete is coming; until then, deletion requests are honored promptly).
Your name, email, password (stored hashed), your family name for the account, and your use of the parent tools. Payments are processed by Stripe; we never see or store your card number.
Reading and phonics lessons can let a child answer by speaking, because saying a word is the skill being learned. This is off unless you turn it on, separately for each child, on your Students page, and you can turn it off again at any time.
When it is on, the microphone is live only while your child is holding the talk button. There is no background listening and nothing is recorded when the button is not held. The recording is turned into text on Clareza's own server, so the teacher can reply to what was said, and then discarded. It is never sent to another company. We never store audio of your child. There is no voice recording in our database, nothing to download, and nothing to delete later, because nothing is kept. The recording is not used to identify your child and is never used for advertising or to train anyone's models.
What Clara sends. Clara, the built-in teacher, is an AI. Each message your child sends her goes to our AI provider, Anthropic, so she can reply. That is how the lesson works, so it is part of the service. The full chat is kept in our database for 30 days, so you can read it on your Students page, and then deleted automatically.
The nightly review. If your family has it switched on, once each night the day's chat is sent to Anthropic again, with instructions to notice only a few specific things: your child asking to have something read aloud, asking for a picture, asking to say an answer instead of typing it, asking what a phrase means, saying a lesson is too long, or saying something unkind about themselves. It is told never to judge spelling, grammar or the way your child writes, and never to guess at a condition or diagnosis. We use what it finds only to suggest learning supports to you. Nothing is switched on without you, and nothing is shown to your child.
What we keep from it. A count for each of those things per day, and, only when your child asked for something, the words they used (so we can show you: “Ava said: can you read it to me”). We keep nothing else from the review.
How it is deleted. Every night an automatic job permanently deletes everything the review stored that is more than 120 days old, from our database, and erases your child's words from any suggestion made from it. Our database backups are kept for at most 14 days and then deleted, so within 14 days after that, no copy remains anywhere. What we keep after 120 days is only the record that a support was suggested and what you chose, with none of your child's words, until your account is deleted.
Your choice. The nightly review is off unless you tick the box for it, under the notice on the signup or billing page, or turn it on on a child's Learning Supports page under “Suggestions from Clara chats”. You can switch it off there at any time. Switching it off stops the review for your whole family and deletes everything it had stored about your children straight away, without waiting for the 120 days. With it off you get no automatic suggestions, and you can still choose every learning support yourself. Families who joined before October 5, 2026 are not reviewed until they say yes.
Safety. Whether or not the nightly review is on, if your child writes something that suggests they may be hurt or in danger, we check that day's chat straight away and, if it looks real, email you and Clareza's owner the same day so a person can follow up. The email tells you how to read the conversation.
On our public pages only (the home page, course pages, the signup page and the like), we use two analytics services to see which pages help parents and where they get stuck: Google Analytics (with Google's advertising features and signals switched off) and PostHog. When you first visit, a notice at the bottom of the page asks whether that is OK.
Do Not Track and Global Privacy Control. If your browser sends either signal, we treat it as “No thanks”: the notice does not appear, and neither service loads.
None of this runs once you sign in. To change your answer, clear this site's data in your browser and the notice will ask again.
The cookies and browser storage we use
_ga and _ga_… (Google Analytics, public pages, only after OK): tell one visit from another. Up to 2 years.ph_…_posthog (PostHog, public pages, only after OK): the same, plus the recording described above. Up to 1 year.cz_consent (ours, stored in your browser): remembers your answer to the notice so it does not ask again. We also keep plain daily totals of how many visitors see the notice and which answer they choose, with nothing about you attached.Payments happen on Stripe's own checkout pages, which set their own cookies under Stripe's privacy policy.
Cloudflare (the secure connection to our own server), Stripe (payments, parents only), Resend (email to parents only, such as password resets), Anthropic (the built-in teacher's replies), OpenAI (reading lesson text and the teacher's replies aloud, which can include your child's first name; it never receives your child's voice), and, on our public pages only, Google Analytics and PostHog (see How we measure our public pages). Each receives only what its job requires.
This is our data retention policy. Nothing is kept indefinitely. Each row says why we keep it and when it goes. Database backups are kept for at most 14 days, so a deleted item is gone from backups within 14 days of its deletion.
| What | Why we keep it | Deleted |
|---|---|---|
| Your child's chat with Clara | So you can read it on your Students page | 30 days after each message, automatically |
| Nightly review counts and the words your child used to ask for something (only if the review is on) | To suggest learning supports to you | 120 days, automatically; at once if you switch the review off |
| A voice recording (only if you switched on answering out loud) | To turn it into text for Clara | Never stored; discarded as soon as it is transcribed |
| Answers, time on lessons, progress, mastery and hours | To run the adaptive lessons and build the transcript you rely on | When you delete the child's or the family's account, or ask us to |
| Your child's first name, sign-in and learning-support settings | To run their account | With the account, as above |
| Which support was suggested and what you decided | To avoid repeating a suggestion you declined, and to check the suggestions help | With the account; your child's words are removed from it after 120 days |
| The date a safety email was sent about a child | So we send at most one a day | With the account; the message itself follows the 30-day chat rule |
| Your own account and billing records | To run your account; payment records as tax law requires | Account data when you delete the account; Stripe keeps payment records for the period the law requires |
See everything we hold about your child from your own account (their answers, chats, supports, and anything the nightly review stored are all in your data export), delete any of it, or tell us to stop collecting from a child, at any time, from the app or by emailing [email protected]. Deleting the family account deletes the children's accounts with it. Because Clara is how the lessons are taught, stopping the sharing with our AI provider means the service cannot run for that child.
Clareza is operated by Professor C's Academy LLC, a company registered in the United States, which is the data controller for everything described above. Privacy questions or deletion requests: the feedback button inside the app, or the account email on your invoice. If we change this policy in a way that matters, we'll tell parents by email before it takes effect.
