Privacy Policy — Uncle Kwaku

Uncle Kwaku is an exam-revision service for university students, on this website, on Telegram and on WhatsApp. It is run by Uncle Kwaku ("we", "us"). This policy explains what we collect, why, who we share it with, and how you can see or delete it. We handle personal data in line with Ghana's Data Protection Act, 2012 (Act 843).

What we collect

Account details: your phone number, the name you give us, an automatically made username, your password (stored only as a one-way hash), and your email address if you add one.
Profile answers you choose to give: your programme, level and how you heard about us.
Telegram and WhatsApp: if you use the bots, your Telegram user ID and username, or your WhatsApp number and profile name.
What you study: your questions and Uncle Kwaku's replies, voice notes (turned into text and not kept as audio), slides and notes you upload, flashcard progress, mock exam answers and results, and your exam timetable.
Payments: the plan you bought, the amount, the date and Paystack's reference. Paystack handles your Mobile Money or card details; we don't see your card number or PIN.
Usage and security: which features you use, daily usage counts, your browser type, and a scrambled form of your network address (not the address itself), so we can stop abuse and fix problems.

Why we use it

To run your account and sign you in, including texting you codes to confirm your phone number.
To answer your questions and personalise your revision, for example by calling you by name and suggesting papers from your programme.
To take payments and give you Pro.
To send exam reminders and weekly revision summaries. You can opt out of promotional messages on your account page.
To keep the service safe and fair, for example through daily allowances and stopping automated sign-ups.
To understand which features help students, using usage counts.

We do not sell your data and we do not show advertising.

Who we share it with

Only the services we need to run Uncle Kwaku, and only what each one needs:

AI provider (Groq): your questions, voice notes, the text of slides you upload, and your first name and programme, so it can write replies.
Meta (WhatsApp) and Telegram: the messages we exchange with you on those apps, under their own privacy policies.
Paystack: payment details when you buy a pass.
Arkesel: your phone number and the text of SMS messages such as verification codes.
Resend: your email address and the content of emails such as password resets, if you added an email.
Our hosting provider: the server and backups where the data is stored.

We may also share data if the law requires it.

How long we keep it

Your account and study data are kept until you delete them, or your account.
The text of messages in our usage log is removed after 90 days; only counts remain.
Phone verification codes are removed after 2 days.
Payment records are kept for our accounts, without your name, phone or email once your account is deleted.
Backups are replaced on a rolling basis, so deleted data disappears from them within 7 days.

Your rights

You can see and correct your details on your account page, and delete your account there at any time. See how to delete your data. You can also ask us for a copy of your data, or object to how we use it: contact us through your account page. If you aren't happy with our answer, you can complain to Ghana's Data Protection Commission.

Cookies and browser storage

We use a cookie to keep you signed in and to protect forms, and your browser remembers settings such as light or dark mode and unfinished mock exam answers. We don't use advertising or tracking cookies.

Security

Connections are encrypted, passwords are hashed, and access to student data is limited to the people who run the service. No system is perfectly secure, so please use a password you don't use elsewhere.

Children

Uncle Kwaku is meant for university students. It isn't meant for children under 16.

Changes

If we change this policy we'll update the date above, and tell you of important changes on the site or in the bots.
