A random ID for your device

The first time you use Wikizen, your browser or phone makes up a random ID and keeps it. It is not your name, email, phone number or advertising ID, and it isn’t derived from anything about you. It is sent with requests so that your listening progress and saved articles come back to the same device.

What is kept on our servers

• Listening progress: for each article you play from the Library, where you stopped, and when.
• Saved articles: the articles you save.

Both are stored against the random ID, in a database hosted by Supabase. Only requests carrying that ID can read them. Live listener counts use the same service: while you listen, a station counts one more listener, under a key made up for that session and never stored.

Like every website and app, the services that deliver Wikizen (Cloudflare for the website and audio, Supabase for the database) see your IP address with each request and keep short-lived logs of them for security and operations. We don’t use those logs to identify listeners.

What stays on your device

The random ID, the article you were last playing and where you stopped, in the app the station you last listened to, and on the website your cookie choice. These are stored in the browser (local storage) or in the app’s own storage.

Analytics on the website

The website uses Google Analytics to count visits and see which stations and articles people listen to (page views, tuning in to a station, playing an article). It asks first: until you accept in the cookie banner, Google Analytics sets no cookies and receives only cookieless signals. Advertising features are always off. You can change your answer at any time with “Cookies” at the bottom of the player. See how Google uses this data.

The Android app has no analytics.

Deleting your data

Unsaving an article deletes it from our servers. Clearing the site’s data in your browser, or clearing the app’s storage or uninstalling it, removes the random ID, and with it the only link between you and your progress and saved articles. To have them deleted from our servers too, write to hi@covalc.com.

Children

Wikizen is not directed at children under 13 and does not knowingly collect anything from them.

The articles

Articles come from Wikipedia, used under CC BY-SA 4.0, and are read aloud by a synthetic voice. Wikizen is not affiliated with the Wikimedia Foundation. Links to Wikipedia and other sites are governed by their own policies.

Changes and contact

If what Wikizen keeps changes (for example, if signing in is added), this page will say so, with a new date at the top. Questions: hi@covalc.com.
