Privacy & Cookie Policy
Last updated: 20 June 2026
KruWai (ครูไหว) respects your privacy. This policy explains what this website collects and how it is used — in particular our use of cookies — in line with Thailand's Personal Data Protection Act B.E. 2562 (PDPA).
Information we collect
This page (the landing site) does not collect personally identifiable information. We use only cookies necessary for the website to function. Sign-up and sign-in take place in our separate student system, which is governed by this same policy.
Our student system (when you sign up or sign in) collects account data such as your name, school, and grade level, along with learning data, in order to provide and improve the service, under this same policy.
Cookies we use
The cookies strictly necessary for the website to function (always on) are:
| Cookie name | Purpose | Type | Duration |
|---|---|---|---|
| kwweb_session | Maintains your session and remembers your chosen language (Thai/English) | Necessary | 120 minutes |
| XSRF-TOKEN | Protects against cross-site request forgery (CSRF) | Necessary / security | 120 minutes |
Analytics tools run only after you accept. Our analytics is cookieless and anonymous (aggregate only). You can change your choice at any time via “Cookie settings”.
Featuring students publicly (website and social media)
We may feature a student's nickname or short name with their grade level, photo, and quiz results on our website and/or social media to promote and showcase success stories. We do this only after obtaining parental/guardian consent, requested separately for each channel (website / social media). We follow data minimization. Parents/guardians may withdraw consent and request removal at any time. Note that content published on social media may be cached or re-shared by third parties, so complete deletion may be limited.
What we don't do
We do not sell your personal data, do not run personalized advertising, and do not build advertising profiles of minors. Our website usage analytics is anonymous.
Legal basis and consent
These necessary cookies operate without prior consent because they are essential to providing the website. If we introduce analytics or marketing cookies in the future, we will ask for your consent first.
Your rights under the PDPA
You have the right to access, correct, delete, object to, or request transfer of your personal data, as well as to withdraw consent and lodge a complaint with the relevant authority.
Managing cookies in your browser
You can delete or block cookies in your browser settings, but disabling necessary cookies may cause some features — such as remembering your language — to work incorrectly.
Third parties and international transfers
We may use necessary external providers, such as anonymous analytics services and social media platforms (only when posting content with consent), some of which may process or store data abroad under appropriate safeguards required by law.
Data retention
We keep data only as long as necessary for the stated purposes. Necessary cookies last about 120 minutes, while learning data in the student system is kept for as long as your account is active or until you request deletion.
Minors
Most of our users are secondary-school students who are minors. For any processing that relies on consent, we obtain consent from a parent or guardian as required by law, and we do not show personalized advertising to minors.
