Privacy Policy — WordFeed

Last Updated: November 9, 2026

This policy explains what the WordFeed app for iPhone and iPad (“WordFeed”, “we”) collects, why, who processes it for us, and how you can have it deleted.

1. Overview

  • You don’t create an account. On first launch the app signs you in with a random anonymous ID. We never ask for your name, email address or phone number.
  • We use your data to run the app, keep your progress and improve WordFeed.
  • We do not show ads, sell your data, or track you across other companies’ apps and websites.

2. Information We Collect

Anonymous identifiers. The anonymous ID created at sign-in, and a random ID the app creates for your device. Neither is your Apple ID or your device’s advertising identifier.

Your answers during setup. How you heard about WordFeed, your age range, gender, native language, whether English is your native language, vocabulary level, learning goal, favorite topics, weekly word goal and background theme. Age range and gender are optional, and you can skip them.

Learning activity. Words you view (and for how long), like, save or mark as mastered; your answers in quizzes and games, with timings and scores; your daily streak; and a backup of the progress kept on your device. Each record carries the app version and the time it happened.

Usage and device data. Screens you open, buttons you tap and other in-app events; session recordings of how you interact with the app’s screens; and your device model, operating system version, language and time zone.

Subscription status. Whether you have WordFeed Premium, which plan, and its trial and renewal dates. Payments are handled by Apple: we never see your card or payment details.

Data that stays on your device. Your settings, widget content, notification reminders and the word list itself are stored on your device. Home Screen and Lock Screen widgets read only data the app saved on the device.

3. How We Use Information

  • To personalize your word feed, quizzes and games to your level, goal and topics
  • To save your liked and mastered words, streak and progress, and to keep them in sync
  • To unlock Premium features after a purchase and restore them later
  • To understand how the app is used, find bugs and decide what to improve

We do not use your data for advertising or for profiling unrelated to the app.

4. Service Providers

We share data only with providers that process it on our behalf to run WordFeed:

  • Supabase: anonymous sign-in and the database that stores your setup answers, learning activity and progress.
  • RevenueCat: manages subscriptions and receives your purchase status with your anonymous ID.
  • PostHog: product analytics (in-app events and your setup answers, linked to your anonymous ID).
  • Microsoft Clarity: session recordings and heatmaps of how screens are used.
  • Google Firebase Analytics: app usage statistics.
  • Google Gemini API: generates word details, translations and quiz questions. It receives words, sentences and the target language, never your identifiers or setup answers.
  • Apple: processes in-app purchases under Apple’s Privacy Policy.

These providers may process data in the United States and other countries. We do not sell or rent your data, and we disclose it otherwise only if the law requires us to.

5. Retention and Deletion

  • We keep your data while you use WordFeed and delete it when it’s no longer needed.
  • Uninstalling the app removes the data stored on your device. It does not remove the copy on our servers.
  • To have your server data deleted, or to get a copy of it, email udapps@icloud.com. Because there is no account, we may ask for details that help us find your data, such as when you installed the app.
  • You can cancel a subscription at any time in your App Store account settings.

6. Children

WordFeed is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has used the app, contact us and we will delete the data.

7. Security

All connections to our services use encrypted HTTPS, and our providers protect the data they store for us.

8. Your Rights

Depending on where you live, you may have the right to access, correct, delete or object to the use of your data. Email us to use any of these rights.

9. Changes to This Policy

When we change this policy we update the date at the top. The current version is always on this page, which is linked from the app and its App Store page.
