Phassa Thai Terms of Use

Last updated: 28 September 2026

These terms apply to Phassa Thai on the web (phassa-thai.app), Android and iOS. By creating an account or using the app you agree to them. If you don't agree, please don't use Phassa Thai.

A free service, supported by ads

Phassa Thai is free to use. In return, it shows ads, on every version of the app (web, Android and iOS). Showing ads is part of the free service. By using Phassa Thai for free, you agree that ads are shown to you as described here:

• Banner ads at the bottom of the home and settings screens.
• Occasional full-screen ads between lessons (never in the middle of an exercise).
• Optional rewarded ads. When you run out of hearts, or after finishing a lesson, you can choose to watch an ad to keep going or to double the XP you earned. Watching these is always your choice.

Ads are provided by Google (AdSense on the web, AdMob in the phone apps). Where the law requires it, for example in the EEA, the UK and Switzerland, you're asked for consent about how ads use your data. See the privacy policy for details. Some partner programmes (for example schools or organisations we work with) may offer ad-free access by separate agreement.

Please don't interfere with the ads (for example by tampering with the app), and don't click ads unless you're genuinely interested in them.

Your account

• You sign in with Google or Telegram. Keep that account secure; you're responsible for activity on your Phassa Thai account.
• Your account is for your own personal learning. Don't share it or use the service to disrupt it for others (for example by automated requests).
• You can ask us to delete your account at any time (see the privacy policy).

Course content

Lessons follow the FSI Thai Basic Course (public domain), via thai-notes.com. Some example sentences come from Tatoeba (CC BY 2.0 FR). Word pictures use Fluent Emoji © Microsoft and flag-icons © Panayiotis Lipiridis (both MIT License). The Phassa Thai app, its design and exercises are ours; you may use them for your own learning.

No guarantees

We work hard to keep lessons accurate and the service running, but Phassa Thai is provided "as is", without guarantees that it will always be available, error-free or suitable for a particular purpose. As far as the law allows, we aren't liable for losses from using, or not being able to use, the app.

Changes

We may change the app, these terms or how ads are shown. If these terms change, we'll update the date at the top of this page. Continuing to use Phassa Thai after a change means you accept the new terms.
