Privacy policy
This page explains StockLab+'s current data practices and the disclosures needed before any future advertising is enabled.
Last updated: 31 August 2026
Inputs and browser storage
No registration is required. Tools with autosave store calculation inputs in browser localStorage. Language selection uses a NEXT_LOCALE cookie. You can clear site data in your browser, which also removes saved settings.
Shared links
Sharing encodes calculation inputs after the # in the URL. This is not encryption: anyone with the link may read those values. Do not include sensitive information in shared content.
Operations and third parties
Cloudflare provides hosting and network security. Requests may involve IP addresses, browser details, URLs, timestamps and error logs to operate and troubleshoot the service. Quote requests send ticker-related queries from our server to Yahoo Finance and cache the results.
Contacting us
Information and contact details you voluntarily send through WhatsApp are used to handle your enquiry. WhatsApp processes data under its own policies. Use our contact page for access, correction or deletion requests, and avoid sending unnecessary sensitive data.
Google Analytics and advertising
StockLab+ uses Google Analytics 4 (G-KTCH2C0XEM) to understand visits, traffic sources and site usage. Google may use analytics cookies and process device, browser and page interaction data. We do not add calculation inputs or saved scenarios to analytics events. Google signals and advertising-personalisation signals are disabled in our tag configuration. You can block or clear cookies through your browser and use Google's Analytics opt-out browser add-on. AdSense advertising is not enabled. Before enabling ads, we will update this policy and the required consent settings. See Google's privacy policy below for its data practices.
