Privacy Policy

Last updated: 1 October 2026

In short: Yak has no accounts and does not collect your name, email, voice, location, or contacts. Your saved words and learning progress stay on your device. We don't sell data, show ads, or track you across apps.

This policy explains how Viral App Brewery Pte. Ltd. (“we”, “us”) handles information when you use the Yak app (“Yak”, “the app”) and this website.

1. Information we do not collect

No account or sign-up: we don't ask for your name, email address, or phone number.
No microphone, camera, contacts, photos, or location access. Yak only plays audio; it never records or listens.
No advertising identifiers and no cross-app tracking.
No payment card details — purchases are handled entirely by Apple.

2. Information stored only on your device

To make the app work, Yak stores the following locally on your iPhone: words you save, flashcard review history and schedule, which clips you've watched or liked, and your settings (such as Simplified or Traditional Chinese). This data is not sent to us. Deleting the app deletes it.

3. Information processed to deliver content

When you use Yak, the app downloads video clips and their subtitles from our content providers: Supabase (clip information) and Cloudflare (video delivery). Like any internet request, these requests include technical information such as your IP address, device type, and operating system version. We use this only to deliver content and keep the service secure and reliable; we do not use it to identify you or build a profile. These providers may keep short-term server logs under their own privacy policies.

4. Subscriptions

Subscriptions are purchased and managed through your Apple ID. Apple processes your payment and shares with the app only what's needed to confirm that your subscription is active. See Apple's Privacy Policy.

5. Learning content

Subtitles, definitions, translations, and pronunciation guides are prepared in advance on our servers, partly with the help of AI tools. No personal data from you is used to create them.

6. Children

Yak is not directed to children under 13, and we do not knowingly collect personal information from children.

7. Your rights

Because we don't hold personal data about you, there is usually nothing for us to access, correct, or delete — your learning data lives on your device and you control it. We comply with Singapore's Personal Data Protection Act 2012 (PDPA) and, for users in the EU/EEA and UK, the GDPR. If you are in one of these regions, California, or anywhere else with privacy laws, you may still contact us with any request or question and we will respond within the time required by law.

8. Changes

If we change how Yak handles data, we will update this page and the “Last updated” date above. Significant changes will be explained in the app's release notes.
