This Policy is written to reflect the principles and obligations set out in Tanzania’s Personal Data Protection Act, 2022 (“PDPA”) and its regulations, and is consistent with the consumer-protection principles that apply to electronic communications services regulated by the Tanzania Communications Regulatory Authority (“TCRA”).

We collect personal data in the following ways:
a) Information you give us directly — when you contact us by phone, WhatsApp, or email, or purchase a digital product (such as our ebooks) from us, we may receive your name, phone number, email address, and the content of your messages.
b) Payment information — when you pay via M-Pesa Lipa Namba, the mobile money transaction is processed directly between you and your mobile network operator (e.g. Vodacom M-Pesa). We do not collect or store your M-Pesa PIN or full financial account details; we only see the transaction reference and phone number you share with us to confirm your order via WhatsApp.
c) Technical and usage information — when you browse the Site, our hosting and caching systems automatically log standard technical data such as your IP address, browser type, device type, pages visited, and the date/time of your visit, for security and performance purposes.
d) Cookies and similar technologies — see “Cookies and Tracking Technologies” below.
e) Information from analytics and advertising tools — where enabled, tools such as Google Analytics, Meta (Facebook/Instagram) Pixel, and TikTok Pixel may collect information about how you interact with the Site and our advertisements, including device identifiers, approximate location, and browsing behaviour, for analytics and ad-performance purposes.
We use personal data to:
Under the PDPA, we process personal data on one or more of the following bases: your consent (e.g. when you choose to message us or opt into marketing/analytics cookies); the performance of a transaction you have requested (e.g. fulfilling an ebook purchase); our legitimate business interests, such as responding to enquiries and improving our services, balanced against your rights; and compliance with a legal obligation.
The Site uses cookies and similar technologies for three general purposes:
You can control or delete cookies through your browser settings at any time. Blocking cookies may affect how parts of the Site function. Where required by the PDPA, we will seek your consent before activating non-essential cookies.
We do not sell your personal data. We may share it with:
We keep personal data only for as long as necessary for the purposes described in this Policy, or as required by Tanzanian law, after which it is securely deleted or anonymised. WhatsApp message history and order records are generally kept only as long as needed to fulfil your order and handle any related queries.
We take reasonable technical and organisational measures to protect personal data against loss, misuse, unauthorised access, disclosure, or alteration. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
Some of the third-party tools we use (such as Google Analytics, Meta Pixel, TikTok Pixel, and our hosting/security providers) may process data on servers located outside Tanzania. Where this occurs, we rely on the safeguards required under the PDPA, including using providers that offer an adequate level of data protection or that have entered into appropriate data protection arrangements.

To exercise any of these rights, contact us using the details in “Contact Us” below.
The Site and our services are not directed at children, and we do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us so we can delete it.
The Site may contain links to third-party websites or platforms (such as WhatsApp, Instagram, Facebook, or TikTok). We are not responsible for the privacy practices of those third parties, and we encourage you to review their privacy policies separately.
We may update this Privacy Policy from time to time to reflect changes in our practices or Tanzanian law. The “Last updated” date at the top of this page shows when it was last revised. We encourage you to review this Policy periodically.
If you have concerns about how we handle your personal data, please contact us first so we can try to resolve the matter. You also have the right to lodge a complaint directly with Tanzania’s Personal Data Protection Commission (PDPC).
