Privacy Policy
Effective date: September 13, 2026
This trading cost estimator can be used without registration. Only when you choose to request a full report will we ask for your email address or WhatsApp number; the site also measures page usage. The following describes all data processing that actually takes place on this page.
SlipLens does not require registration. Except for the email address or WhatsApp number you voluntarily provide when submitting your contact details, we do not ask for your name, identity information, or trading account credentials. Technical data generated: when you visit the site, the server and hosting provider record standard access logs (IP address, access time, and browser identifier). These logs are used only for security and troubleshooting and are retained for a short period under standard retention practices.
Your analysis records, including calculation history and watchlist instruments, are stored only in your browser's local storage and are not uploaded to our servers. They will disappear if you clear browser data, use private browsing, or change device or browser. Your language preference is stored in a cookie named sliplens.lang.v1.
Local records are used only to display history and analysis results on your device. Your language preference is used only to retain your selected language for your next visit. We do not sell your personal information. If analytics or advertising platforms are enabled, they are used only to measure site traffic and advertising performance and not for purposes unrelated to this site.
The following categories of third parties may be involved: (1) market data providers, which receive only market data requests and not your local records; (2) server and hosting providers, which process server access logs; and (3) analytics and advertising platforms, which are used with your consent to measure site traffic and advertising performance. Other than these categories, we do not sell, provide, or share your information with any third party.
Local records remain until you delete them or clear your browser data. Server access logs are retained for a short period under standard operating practices. This site does not store payment information, account credentials, or sensitive personal information.
You may clear your browser data at any time to delete all local records. You can also delete individual records on the Analysis Records page. For privacy-related questions, contact us using the email address below.
If this policy changes, we will update the effective date at the top of this page. By continuing to use the site, you accept the updated version.
