Overview
Bottleneck Calculator is a free CPU and GPU bottleneck tool that processes calculator requests on the server and aims to collect as little personal information as possible. You can check your PC build without creating an account.
Local Storage
Your browser may store a theme preference (dark or light) in local storage so the site remembers your choice. This preference stays on your device and is not sent to us or shared with third parties.
Contact Form
If you contact us, we store your name, email, topic, and message so we can respond to your request. We may also store IP address and user agent to help prevent spam and abuse of the contact form.
Calculator Usage
The CPU, GPU, resolution, RAM, and storage selections you enter are validated against our hardware database to produce a bottleneck result. We do not require an account, and we do not sell your data or build advertising profiles from your calculator inputs.
Third-Party Services
We may load web fonts from Google Fonts to display the site, and email delivery may use a configured SMTP or mail provider to send contact-form responses. These providers process only the data needed to deliver their service.
Your Choices
You can clear your browser local storage at any time to remove the saved theme preference, and you can ask us to delete a contact message you sent by reaching out through the Contact Us page.
