Privacy Notice

CherCounts is a study platform for Singapore Secondary 3 and 4 Principles of Accounts students. This notice explains, in plain English, what personal data we collect, why, how long we keep it, and the choices you have. If anything here is unclear, please ask us.

Who we are

CherCounts is created and run by Ms Peng, in Singapore ("we", "us", "our"). You can reach us at support@chercounts.com.

What we collect

• Your email address — so we can sign you in. Sign-in is passwordless: we never ask for or store a password.
• Your level — whether you study at G2 or G3, so we show you the right content.
• Your progress — the self-marks you give yourself on practice questions ("Got it / Almost / Need more practice") and which walkthroughs you have completed, so your progress is there when you return.
• A record of the content pages you open — each time a notes, practice or walkthrough page is served to you, we record your account, which page it was, and the time. This is explained under Watermarking and the page-view log below.
• Anonymous visit counts, on our public pages only — so we can see how many people are finding CherCounts. This is explained under Visitor counts on our public pages below.

We do not collect your name, your school, your age, or any other personal details.

How we use it

• Email: to sign you in, and if necessary to contact you about your account.
• Level and progress: to run the app for you.
• The page-view record: only for content protection, as explained below. We do not use it to track your study habits, judge how much you revise, or report your activity to anyone.
• The visitor counts: only to see how many people arrive at CherCounts and where they heard about it.

Watermarking and the page-view log

The notes, questions and walkthroughs took a lot of work to write. Most of our notes can be read without an account; the rest of the notes, the practice questions and the walkthroughs are for signed-in students. To protect that work, when you are signed in:

• Every page you view carries a hidden mark unique to your account, woven invisibly into the text, and a faint visible watermark showing your email. If a copy of the content is shared or leaked, these let us trace it back to the account it came from.
• We keep a log of which content pages each account opens — your account, the page, and the time.

Because that log records page views, it could in principle answer a question like "did this account ever open Chapter 9". We deliberately do not use it that way. It exists only as an evidence trail to investigate leaked content, and we keep it only as long as that needs (see below).

Visitor counts on our public pages

We would like to know whether people are finding CherCounts at all — for example, how many visitors arrive from the revision guide. So our hosting provider, Vercel, counts visits to our public pages: the home page, the Start here page printed in the revision guide, the Welcome page printed on the worksheets we share with teachers, the About page, the sign-in page, and these Privacy and Terms pages.

• The pages you see once you sign in are not counted. Notes, practice questions, walkthroughs and your library are left out. Which chapters you study is nobody's business but yours, and this is enforced in the site's code, not just promised here.
• It cannot identify you. There are no cookies and no advertising. Visitors are counted using a scrambled code worked out from the visit itself, which is thrown away after 24 hours, and it is never linked to your account or your email.
• What gets recorded for each visit: which of those public pages it was and when, the site or link you came from, the country and city the visit came from, and the general type of device and browser. Nothing else.

This is separate from the page-view log described above, and the two are never joined up.

How long we keep it

• The page-view log is automatically deleted after 90 days. Investigating a leak only ever needs recent history, so we hold less about you while losing nothing we would actually use.
• Your account details and progress are kept while your account exists. Ask us to delete your account and we remove them.
• The visitor counts are totals, not records about a person, so there is nothing in them to delete. The scrambled code used to count a visitor is discarded after 24 hours.

Who else is involved

We do not sell or share your data. We use a few trusted service providers to run CherCounts, and they process data only to provide their service to us:

• Supabase — database and sign-in.
• Vercel — hosting, and the anonymous visitor counts described above.
• Resend — sending sign-in emails.
• Google — only if you choose "Continue with Google".

These providers may store data on servers outside Singapore.

Your choices and rights

Under Singapore's Personal Data Protection Act (PDPA) you can ask us to show you the data we hold about you, correct it, or delete it. Email support@chercounts.com and we will respond.

For students and parents

CherCounts is intended for Secondary 3 and 4 students, who are usually under 18. We keep the data we collect to the minimum listed above. If you are a parent and have questions, or would like your child's account removed, please contact us.

Changes to this notice

If we change this notice, we will update the date at the top of this page, and show any significant change the next time you sign in.
