Calculator and editor data
Values entered into calculators and the formula editor are processed in your browser and are not intentionally transmitted to our servers. Shared URLs may contain an expression or formula that you choose to include.
Contact communications
When you use the contact form, the name, email address, enquiry type, optional page URL, message, submission time, and a one-way hash used for abuse prevention are stored in isolated STEM Hub Supabase tables. Only authorized STEM Hub administrators can read and manage messages. We reply separately by email. Do not submit confidential information.
Retention
Contact messages are retained only while needed to respond, maintain an appropriate correspondence record, or address abuse, after which an administrator may archive or delete them. Rate-limit records contain a one-way hash rather than the original network address and are used only to prevent form abuse.
Current status
No analytics provider, advertising tag, or Google CMP is active by default. AdSense and Google's certified CMP activate only after approval, publication of the European regulations message, and complete production configuration. We do not create our own IAB TCF string.
Future Google CMP and AdSense mode
If activated, Google's certified CMP will manage advertising consent and IAB TCF signals. Depending on your choices, Google and the vendors disclosed in that message may process identifiers, device and usage information, approximate location, consent records, and ad interactions for delivery, measurement, security, fraud prevention, and personalisation.
Your choices
In the current mode, use Privacy choices in the page corner or footer to change Preferences and Analytics choices. In future Google CMP mode, the same controls reopen Google's official revocation flow. Refusing optional consent does not restrict access.
