Terms
Terms of use
These terms cover stringspec.com and the StringSpec connector at https://stringspec.com/mcp.
StringSpec is run by BigBalli (contact [email protected]).
Using either one means you accept them. Last updated 6 October 2026.
What StringSpec is
StringSpec publishes lab measurements of tennis strings and figures derived from them, such as percentiles, playable life, tension advice and recommendations. The site and the connector are free and need no account. Both are for information. A string that measures well still has to suit your racquet, your tension and your arm, and nothing here is medical advice: if you have arm or elbow pain, see a doctor or physiotherapist.
No warranty
The data is provided as is. Measurements can contain errors, manufacturers change products, and prices are a retailer's set price from the last check, not live prices. StringSpec is not liable for decisions or purchases made on the strength of this data, to the extent the law allows.
Fair use
You may use the site and the connector for your own research and to answer questions, including through an AI assistant. You may not copy the database in bulk, scrape it, resell it or get around the rate limits. Requests over those limits are refused.
Shops and other sites
Links to retailers take you to sites StringSpec does not run. Their prices, stock, terms and privacy policies apply there.
Changes and contact
These terms can change; the date above shows the latest version. What StringSpec collects is in the privacy policy. Questions go to [email protected].
