Privacy Policy
Last updated: November 8, 2026
Summary
- You can use Wono IELTS without an account. We do not ask for your name or email to practise.
- Your Writing answers and Speaking recordings are sent to our servers only to score them, then passed to the AI providers listed below. We do not keep them on our servers after your result is returned.
- Your practice history, drafts and settings are stored in your own browser (local storage), not on our servers.
- We do not use advertising or tracking cookies, and we do not sell your data.
Who we are
Wono IELTS ("we", "us") runs the website at ielts.wono.app. For anything about this policy or your data, write to halo@wono.app.
What we process and why
| Data | When | Why | Legal basis (GDPR) |
|---|---|---|---|
| Writing answers (text) | When you submit an answer for scoring | To estimate your band and give feedback | Performing the service you asked for (Art. 6(1)(b)) |
| Speaking audio | Only while you record an answer | To transcribe it, score it and (if enabled) assess pronunciation | Performing the service you asked for (Art. 6(1)(b)) |
| Technical data (IP address, browser type, request logs) | On every visit | To deliver the site, keep it secure and fix errors | Legitimate interests (Art. 6(1)(f)) |
The microphone is only used after you allow it in your browser, and only while a recording is in progress.
Who processes your data for us
To score your answers we use these providers. They process the data on our behalf, only to perform the task:
- DeepInfra: speech-to-text, AI scoring and feedback, and examiner voice.
- Microsoft Azure Speech (when enabled): pronunciation assessment of Speaking recordings.
- Our hosting provider: runs the website and our servers.
When you open the practice dashboard, your browser also downloads an open-source voice model from Hugging Face, which sees your IP address like any website you load files from. These providers may be located outside your country, including in the United States. Where the GDPR applies, such transfers rely on safeguards such as the EU Standard Contractual Clauses.
What stays in your browser
The following is stored only in your browser's local storage, on your device:
- your last 100 practice attempts and their scores (the History page),
- unfinished Writing drafts,
- preferences such as subtitles and the timer.
This data never leaves your device unless you submit a new answer for scoring. You can delete it at any time by clearing this site's data in your browser settings. If you switch browsers or devices, your history does not come with you.
Cookies
We do not use advertising, analytics or tracking cookies. The site may use storage that is strictly necessary for it to work (for example remembering your language or your practice history), which does not require consent. If we ever add analytics or marketing tools, we will ask for your consent first and update this policy.
How long we keep data
- Answers and recordings: not stored on our servers after scoring. Our providers handle them under their own retention terms for processing.
- Server logs: kept for a short period for security and troubleshooting, then deleted.
- Browser data: stays until you delete it.
Your rights
Depending on where you live (for example under the GDPR in the EU/UK, the CCPA in California, or Indonesia's Personal Data Protection Law), you can ask to access, correct, delete or restrict the processing of your personal data, object to processing, or receive a copy of it. Because we do not run accounts, we usually cannot link stored data to you, but write to halo@wono.app and we will help. You also have the right to complain to your local data protection authority.
Children
Wono IELTS is not intended for children under 13. If you are under 16 and live in the EU/UK, please use the service only with the consent of a parent or guardian.
Changes to this policy
If we change how we handle data, we will update this page and the "Last updated" date above. Significant changes, such as introducing accounts or analytics, will be announced on the site.
