Privacy Policy
Last updated: 4 November 2026
This policy explains what data Wordly Go collects, why, who we share it with and what rights you have. We collect only what learning and running the service require, and process personal data in line with Vietnamese personal data protection law.
1. Data we collect
- Account details from Google when you sign in: name, email address and profile picture.
- Learning data: words and notes you save (with example sentences and source articles), review schedule and results, dictation progress, articles read and study days.
- Preferences: interface language and review settings (in your account); light/dark theme and text size (on your device).
- Plan and payment data: order code, plan, amount, creation and confirmation time, order status and Premium end date. When matching transfers or refunding, we see bank transaction details such as the sender's name, time and transfer content.
- Technical data: sign-in session cookies, a timezone cookie (wordly_tz) so reviews follow your local day, and aggregated, non-identifying visit statistics.
We never collect card numbers, banking passwords or OTP codes.
2. How we use it
- To provide learning features: saving words, scheduling reviews, saving progress and statistics.
- To manage Premium: creating orders, matching transfers, activation, extension and refunds.
- To help when you contact us, send feedback or report a bug.
- To protect the service against abuse, account sharing and unauthorised access.
- To improve content and features based on aggregated usage.
We do not sell personal data and do not use your data for personalised advertising.
4. Storage and security
- Data is transmitted over encrypted connections (HTTPS).
- The database uses row-level permissions: each account can read only its own data, and plan and payment data can be written only by the server.
- Learning data is kept until you ask us to delete your account. Order records may be kept longer where needed for reconciliation, disputes and legal requirements.
5. Your rights
- View and edit your words, notes and preferences directly on the website.
- Get a copy of your data: Premium members can export the notebook to CSV/Anki; anyone can request a copy by email.
- Ask us to delete your account and learning data; we do so within 30 days.
- Withdraw consent by stopping use and requesting deletion.
Send requests from your sign-in email to nykhoa2405@gmail.com so we can verify you own the account.
6. Users under 16
Users under 16 need a parent's or guardian's consent. If you are a parent and believe your child provided data without consent, contact us and we will handle it.
7. Changes
When this policy changes, the update date at the top changes too; important changes are announced on the website.
