Privacy Policy
Last updated: 8 July 2026
WordSpark is a vocabulary-learning app that helps you learn English through games, daily
practice, and a friendly AI tutor. We care about your privacy and we keep things simple:
almost everything stays on your own device, and we do not sell your data or show you ads.
This page explains, in plain language, what information the app uses and why.
The short version
- Your name, your chosen location, and all your learning progress are saved on your
own device — not on our servers.
- When you chat with the AI tutor or ask it to check a sentence, that text is sent to a
third-party AI service so it can reply. Nothing more.
- We do not sell your data, we do not show ads, and we do
not track you across other apps or websites.
What information the app uses
- Your name — the name you type during setup, used only to greet you inside
the app. It stays on your device.
- Your location — the city or country you choose to enter. It is used to
translate words into your language and to show a local weather greeting. We use only what
you type; we do not read your phone's GPS.
- Your writing and chat messages — the sentences you write for practice and
the messages you send to the AI tutor. These are sent to a third-party AI service so it can
check your answer or reply to you.
- Your learning progress — words learned, scores, streaks, and settings.
This is saved in your device's local storage so the app remembers where you left off.
Where your information is stored
Your name, location, progress, streaks, and settings are stored locally on your
device using your browser's storage. We do not keep a copy on a server, and there is
no account or login. If you clear the app's data or uninstall it, that information is gone.
Third-party services we rely on
To provide some features, the app sends certain information to trusted third-party services:
- An AI service (used for the AI tutor, sentence checking, and example
generation) — receives the text you send so it can generate a response.
- A weather / web lookup — used to create your local weather greeting, based
on the location you entered.
- A dictionary service — used to look up definitions when you tap a word.
These services process the information only to return a result to the app. Please
refer to the respective providers' own privacy policies for how they handle data.
What we do NOT do
- We do not sell, rent, or trade your personal information.
- We do not show advertising.
- We do not track your activity across other apps or websites.
- We do not require you to create an account.
Children
WordSpark is intended for learners aged 13 and older. It is not directed at children under 13,
and we do not knowingly collect personal information from children under 13.
Changes to this policy
If we make meaningful changes to how the app handles information, we will update this page and
change the "Last updated" date above.
