Privacy and local data

Calculations and input files

Tire and wheel calculations run in the browser. Selecting a JSON file for import allows the application to read that file locally so it can validate and preview the project. The application has no project-upload endpoint and does not send the file to an AI service.

Browser-local storage

When you save a named comparison, the project and its settings are written to storage associated with this site in the current browser profile. Preferences such as the selected theme may also be stored locally. This is separate from an account: there is no sign-in or automatic synchronization. Other people with access to that browser profile may be able to view local projects.

Your choices and deletion

You can use temporary mode without persistent project saves, delete an individual saved project, or clear the site’s data through your browser. Clearing site data can also remove preferences. Keep a downloaded JSON backup if you want to restore a project later; the application has no remote backup to retrieve.

Downloaded files

Exports are generated in the browser. After you save a file, it is managed by your device, browser and any service to which you choose to upload it. A report may include a project name and input values. Review its contents before sharing it.

Page delivery and hosting

The website is delivered through Cloudflare. Requests for pages and assets may include connection and request information that Cloudflare processes to deliver and protect the service, as described in its privacy policy. TireSpan has no project-upload endpoint or server-side project database.

Advertising and analytics

This edition contains no enabled advertising, analytics or consent-platform integration. Reserved layout space does not itself load an advertising script. If a future release adds those services, its data practices and any required choices must be reviewed and this notice updated before activation.

External source links

Manufacturer and reference links take you to other websites with their own policies. TireSpan does not control their content or tracking. Opening a source link is separate from performing a local calculation.

Privacy contact

This website operates under the public name TireSpan. Email support@tirespan.site for privacy questions or requests concerning messages you have sent.

Email is separate from the local calculation tools. Your email provider and the forwarding and receiving services process messages you choose to send. TireSpan uses that correspondence to address your request; do not send passwords, payment information or unnecessary personal files. TireSpan cannot retrieve browser-local projects or delete files already saved on your device.
