Mwangaza Yield

Privacy policy

We do not collect your personal data, because the app has nowhere to send it.

Last updated 25 July 2026

The short version

Mwangaza Yield has no user accounts, no login, and no server that stores anything about you. Everything you enter — amounts, holdings, goals — is computed on your own device and saved only in your browser's local storage (IndexedDB). It never leaves your phone or computer.

What we store, and where

  • Your portfolio and imported CSV data — stored locally in your browser only. Clearing your browser data or tapping “Clear all holdings” deletes it permanently. We cannot recover it, because we never had it.
  • Market data — bond, bill, auction and macro figures are downloaded to your device and cached so the app works offline. This is public information flowing to you, not data flowing from you.
  • No cookies are set for tracking, advertising or profiling.

What our host can see

The site is served as static files by Netlify. Like any web host, Netlify processes standard server request data (IP address, browser type, pages requested) to deliver the site and protect it from abuse. We do not add analytics, advertising trackers, or third-party scripts on top of that. Fonts are served from our own domain rather than a third party, so loading a page does not notify anyone else that you did.

Links away from the app

We link to the Central Bank of Kenya, the NSE, KNBS and CBK's WhatsApp channel. Once you follow a link you are on their service, under their privacy policy, not ours. Sharing a summary to WhatsApp hands that text to WhatsApp — we neither see nor keep a copy.

Children

The app is intended for adults able to hold a CSD account. We do not knowingly collect information from anyone — a promise that is easy to keep given we collect none at all.

Your rights

Kenya's Data Protection Act, 2019 gives you rights over personal data held about you. Because we hold none, there is nothing for us to disclose, correct or erase on request — your data is already exclusively in your own hands. If that ever changes, this page will change first, and the date above will say so.
