Privacy Policy

Last updated: 17 July 2026

KEFAS is a multilingual reading app. This page explains what information the app collects, why, and how you can have it deleted.

What we collect

• Email address — used to log you in, deliver your access code, and send account-related messages.
• A device identifier — a random ID generated on your device (not tied to your hardware), used only to bind your access code to your device so it can't be shared or reused elsewhere.
• Reading progress — which book, page, and sentence you're on, so you can pick up where you left off on any device.
• Saved vocabulary — words and phrases you save while reading.
• Words you look up — sent to our server to fetch a translation or conjugation; not stored beyond what's needed to return the result, other than words you explicitly save (above).
• Phone number — only if you pay via mobile money (Airtel, Vodacom, Orange, M-Pesa, etc.); used solely to initiate that one payment through our payment provider, PawaPay.

Payments

We never see or store your card details. Card payments are processed entirely by Stripe; mobile money payments are processed by PawaPay. We only receive confirmation that a payment succeeded or failed, plus the email/phone number needed to identify which purchase it was.

What we don't do

• No advertising and no ad networks.
• No analytics or tracking SDKs (Google Analytics, Facebook, etc.).
• No access to your camera, contacts, location, or photos — the app only ever uses your internet connection (and your microphone, only when you choose to record a reading for pronunciation feedback).
• We don't sell your data to anyone.

Where your data is stored

Account and reading data is stored on our backend server. Your reading library and local preferences also live on your own device and are not affected by deleting your server-side account.

Deleting your data

To delete your account and all associated data, email contact@571185460.swh.strato-hosting.eu from the email address on your account and ask for deletion. We'll confirm once it's done, normally within a few days. You can send this request whether or not you still have the app installed.

This deletes your email, device binding, reading progress, and saved vocabulary. Records of completed payments (amount and date, not card details — we never see those) are kept afterward where we're legally required to retain them for accounting/tax purposes, for as long as that law requires.

Children

KEFAS is not directed at children under 13, and we don't knowingly collect data from them.

Changes to this policy
