Privacy policy
A child is on the other end of this. Everything below is written from the code, so you can check it against what the software does.
Version 1.0 · Controller: [Operator legal name], [Country of establishment] · [KVKK iletisim adresi]
1. What we hold, and why
This is the whole list. If something is not here, we do not collect it.
| What | Why | Where it goes | Kept? |
|---|---|---|---|
| Student's name and year or level note | So the teacher greets the right child and pitches the lesson | Stays on the machine running TeacherKit | Yes, until deleted |
| A phone number | Only to deliver notes and homework on WhatsApp | Stays on the machine; used with WhatsApp if paired | Yes, until deleted |
| The student's voice, live | It is the lesson | Streamed to Google's Gemini Live API | No audio is stored |
| A transcript of what was said | To write the notes and to resume a dropped session | Stays on the machine; excerpts go to Gemini for the rolling summary and the notes | Yes, until deleted |
| What was written and drawn on the board | To replay the board if the tab reloads, and to write the notes | Stays on the machine | Yes, until deleted |
| Single camera frames | Only when the teacher asks to look at something | Sent to Gemini for that turn | Not stored |
| Screen share | Only while the student holds it open | Streamed to Gemini while on | Not stored |
| Files placed on the board | So the teacher can work through them | Text is extracted on the machine; the extract goes to Gemini | The extract stays in the lesson record |
| Durable notes about the student | So the teacher remembers them next time | Stays on the machine | Yes — see section 3 |
| Notes and the homework PDF | The point of the lesson | On the machine, and to WhatsApp if paired | Yes, until deleted |
There is no analytics service, no advertising pixel, no third-party font or CDN, and no cookie set by this website. Nothing on these pages tracks you.
2. Who else processes it
| Processor | What they get | When |
|---|---|---|
| Google (Gemini API) | Live audio, requested camera frames, screen share while on, transcript excerpts, extracted file text, and the material used to write notes and homework | Every lesson — the teacher is a Gemini model |
| Meta (WhatsApp) | The phone number, the notes message and the homework PDF | Only if a WhatsApp number has been paired |
| iyzico | The card, and the name and details the card holder types on iyzico's own payment page. We never see or receive the card number — we are handed back only the brand, the last four digits, and opaque references. iyzico also requires a buyer record (name, contact and an identity field) with each payment | Only where lessons are paid for: the first payment, each later charge, each refund |
That is the complete list of third parties. Processing by Google may take place outside your country; where local law requires explicit consent for that transfer, booking a lesson is where it is asked for and you may withdraw it by asking us to stop. iyzico is a licensed payment institution in Türkiye and keeps its own records of a transaction for as long as financial law requires, which is longer than we keep anything and is not ours to erase — deleting a child from this service does not and cannot delete iyzico's record that a payment happened.
3. The teacher's memory of your child
Across lessons, the teacher keeps a small set of durable facts about a student — their level, what they find hard, which examples land. This is what makes the second lesson better than the first.
Two rules constrain it, and both are enforced in the code rather than promised here: a fact may only be written from something that actually happened in a lesson, and every fact carries the identifier of the lesson it came from, so any claim can be traced back to a real transcript. The set is capped, and you can read it, correct it or have it erased on request.
4. How long we keep it
Plainly: there is no automatic deletion. A lesson's record, the notes, the homework and the student's file stay on the machine until somebody removes them. We would rather tell you that than publish a retention period the software does not enforce.
What that means in practice: ask us to delete a student and we delete their folder, their memory file and every lesson recorded against them. On a self-hosted install, that is a directory you can delete yourself.
5. Legal basis
- Performance of a contract — running the lesson you booked, and delivering the notes and homework.
- Consent — given by the parent or guardian for a child's data, including the transfer to the model provider. Withdrawable at any time, which ends the lessons.
- Legitimate interests — keeping the service working and secure, in a way that does not override the child's interests.
6. Your rights, and how to use them
You can ask us to: tell you what we hold, give you a copy, correct it, delete it, restrict what we do with it, or object to it. For a child, the parent or guardian exercises these.
Write to [KVKK iletisim adresi] with the student's name. We will reply within 30 days. There is nothing to prove and no form to fill in — if you booked the lessons, you can ask.
You also have the right to complain to your data protection authority.
7. Security
- The student list, WhatsApp pairing and admin lesson-creation answer requests from the machine itself and nowhere else.
- Lesson and notes links are unguessable random tokens rather than sequential identifiers.
- There are no user accounts and therefore no passwords to leak.
- Public booking is the only unauthenticated write, and it is rate-limited.
- Lesson records are written atomically to flat files, so a crash cannot leave half a record.
No system is perfect. If you find a security problem, write to [KVKK iletisim adresi] and we will credit you if you would like us to.
8. Children
This service is designed to be used by minors. A separate page covers what that means — consent, what the teacher remembers, and how to erase a child completely. It forms part of this policy.
9. Changes
Material changes get a new version line here, and where we hold a contact address we will tell you before they take effect.
Plain English first
If anything on this page contradicts the parents' page, treat the plain-English page as the description of the software's behaviour and this page as the legal commitment — and tell us, because they should never disagree.
