Guitar String Tension Calculator works without an account. Calculator inputs are processed in your browser and are not intentionally sent to our server unless you place them in a contact message or share a URL.
Information you provide
If you submit the contact form, the form provider processes your name, email address, message, and basic request metadata so the message can be delivered. Do not submit confidential instrument-owner, payment, medical, or identity information.
Calculator and shared URL data
Calculator settings may be placed in a URL when you choose “Share setup.” Anyone receiving that URL can read those settings. Shared calculator URLs are canonicalized to the main calculator and are not intended to create separate indexed pages.
Technical data
Hosting infrastructure may process standard logs such as IP address, user agent, request time, and requested path for security and reliability. Retention and processing depend on the hosting provider’s operational policies.
Cookies and local storage
The current theme does not require an account or advertising cookie. If analytics, consent controls, or local preferences are added later, this policy will be updated before those features are enabled.
Your choices
You can use the calculators without contacting us. To request deletion of a submitted message or ask a privacy question, use the contact page and identify the message involved.
