Information you choose to provide
This is a free information website. It does not provide account registration, purchases or payment processing. If you contact OngTeh by email, we may receive your email address, message and any other information you choose to share.
Technical information
Optional Google Analytics is available only after you choose “Allow analytics” in the site notice. Until then, this site does not load Google Analytics. With consent, Google may process usage data and set analytics identifiers according to its terms. Separately, hosting and security providers may process routine technical logs such as IP addresses, browser information and timestamps.
How information is used
Information is used to respond to enquiries, maintain the security and performance of the website, keep appropriate business records and meet legal obligations where applicable. It is not sold.
Sharing and retention
Information may be processed by service providers that support email, hosting, security or professional advice, subject to their own safeguards and terms. We retain information only for as long as reasonably needed for the purpose for which it was collected, a resulting business relationship, security, dispute resolution or legal obligations.
Your choices
You may ask about personal information you have provided, request a correction or withdraw consent for future use where applicable. Some records may still need to be retained for legal, security or legitimate business reasons.
External services and updates
Use “Privacy settings” below to revisit your analytics choice at any time. Declining optional analytics does not stop the core website from working. If forms, ordering or other data features are added later, this notice will be revised before they are used.
