Last updated: November 14, 2026
This page explains how to delete your SAT Vocab Boost (「SAT 單字衝刺」) account and the data associated with it, what happens to that data, and what is kept. The app is published by CORETRIX TECHNOLOGY LIMITED.
Delete your account in the app
- 1 Open the SAT Vocab Boost app.
- 2 Go to 設定 (Settings).
- 3 Tap 帳號 (Account).
- 4 Tap 刪除帳號 (Delete account).
- 5 Confirm the deletion.
No email or support request is required. The deletion is done in the app
and takes effect immediately after you confirm. For reference, the app sends a
DELETE /api/v1/auth/me request to our server.
What is deleted
When you confirm, the following server-side data linked to your account is deleted immediately:
- Account and sign-in data: your member record, email address, linked sign-in methods (Apple, Google, WeChat, or username and password), and login / activity records. (
members,member_activity,member_auth_providers) - Study plan and settings (
user_study_plans,user_app_settings) - Learning progress: words you browsed, your wrong-answer log, your review list, and word-view records. (
user_browsed_words,user_wrong_words,user_review_words,word_views) - Connection and presence data: last-used time and IP address records. (
user_presence) - Purchase records and the daily word email subscription, including the delivery email address. (
purchases,email_subscriptions)
This is permanent and cannot be undone.
What is not deleted
- Store purchase records. The Apple App Store and Google Play keep their own records of your purchases and subscriptions. We do not control those records and cannot delete them.
-
Your subscription is not cancelled. Deleting your account does
NOT cancel a paid subscription. You must cancel it in the store:
- iOS: Settings → Apple ID → Subscriptions, or https://apps.apple.com/account/subscriptions
- Android: Play Store → Payments & subscriptions, or https://play.google.com/store/account/subscriptions?package=com.coretrix.satvocabboost
- Anonymous progress not linked to an account. Learning records stored under an anonymous visitor ID (for example, progress uploaded while signed out) are not tied to an account and are not removed by this request. To clear them, open the app → Settings → Data & Privacy → Reset learning data, or uninstall the app.
- Data on your device. Account deletion is performed on our server. It does not remotely erase the SQLite database on your phone. Use the local reset above or uninstall the app to remove on-device data.
Retention period
Your data is deleted immediately when you confirm. We apply no additional retention period on our side. Our encrypted database backups are rotated out within 30 days.
If you cannot access the app
If you cannot open the app or sign in, email support@coretrix-tech.com from any address and tell us the email address or sign-in method you used for the account. We will process the deletion within 30 days. Please do not send us your password.
