Privacy

This page says what Mozaker keeps about you, why, and who else sees it. We wrote it to match what the site actually does.

What we keep

• Your account: email, the name you type (it is printed on your certificate), phone number if you give one, and the language you chose. Your password is stored scrambled (hashed): nobody, us included, can read it.
• Payments: for each order, the price, any coupon, the photo of your InstaPay transfer, and the sender name, phone and reference you type. You pay InstaPay directly; we never see your bank login or card.
• Your studying: which lessons you opened and finished, time spent, your quiz answers and whether you watched a lesson's video. While you are signed out this stays in your browser only. Once you sign in, it is saved to your account so it follows you to other devices.
• Hand-ins: the text, links and files you hand in for projects and exercises, the grades and feedback, and the messages between you and the reviewer.
• Problems you report and our answers, and the notifications we show you on the site.
• Certificates: the name printed on it, the course, the date and its code.
• Security records: failed sign-in attempts with the address they came from, so we can stop someone guessing passwords.

Who sees it

• The course owner, and anyone the owner adds to help with reviewing payments or grading. Staff accounts sign in with two-step sign-in.
• Anyone with a certificate's code or link can open its check page, which shows the name on it, the course, the date and whether it is valid. Nothing else about you is on that page.
• Email: to send you emails (confirming your address, receipts, reviews) we hand your email address and the message to an email delivery service.
• YouTube: lesson videos are YouTube videos. Nothing loads from YouTube until you press play. After that, YouTube (Google) handles the video under its own privacy policy.

We don't sell your data, we don't show ads, and the site has no analytics or tracking scripts.

Cookies and your browser

The site sets a few cookies that it needs: one keeps you signed in and one protects forms from being sent by another site. Your browser also keeps your reading progress and settings (day or night theme, text size, the width of the lesson list) so the site remembers them. No advertising or tracking cookies.

Payment photos and hand-in files

These files are never public. Only you and the staff can open them, and the site checks who is asking every time.

How long we keep it

For as long as you have an account. If you ask us to delete your account, we delete it along with your progress, hand-ins and messages. We may keep the record of a payment (order number, amount and date) where we need it for our own accounts.

What you can ask for

• To change your name, phone or language: do it yourself in your account settings.
• A copy of what we keep about you, a correction, or deleting your account: write to us at the address below.
