Privacy

This static website does not require an account to use the calculator, TI-BASIC Studio, Program Runner or learning guides.

External calculator runtime

The calculator loads files from an external TestNav service. When your browser requests those resources, the external provider may receive ordinary web-request information such as IP address, browser information and request timing under its own policies.

TI-BASIC Studio and Program Runner

TI-BASIC Studio reads imported .txt, .8xp and .8xp2 files locally in your browser. Encoding, decoding and CE/Evo conversion also run in the browser. Program Runner executes supported source inside a separate browser worker. These tools do not upload program files or source to an account, public project or conversion service.

Hosting logs and analytics

Your web host may keep standard server logs. If analytics or advertising is added later, this privacy page should be updated before those services are enabled.

Browser storage

The calculator wrapper may store a display-scale preference. TI-BASIC Studio stores the program name, readable source and selected target in your browser so work can be restored. Clearing site data removes these saved preferences and drafts.
