Last Updated: December 2025
Introduction
LinkStack is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our platform to manage your digital identity and links.
Information We Collect
- Account Data: We store your email address and encrypted credentials via Supabase Authentication.
- Profile Information: We store the handles, bios, avatars, and social media usernames you choose to display.
- Link Data: We store the URLs and labels you add to your public profile.
- Analytics: We collect aggregate data on link clicks and page visits to provide insights into your audience engagement.
Spam Protection (hCaptcha)
We use the hCaptcha anti-bot service on our website. This service is provided by Intuition Machines, Inc. hCaptcha is used to check whether the data entered on our website (such as on a login or registration page) has been entered by a human or by an automated program.
hCaptcha analyzes the behavior of the website visitor based on various characteristics. This analysis starts automatically as soon as the website visitor enters a part of the website where hCaptcha is active. For the analysis, hCaptcha evaluates various information (e.g. IP address, how long the visitor has been on the website, or mouse movements made by the user).
Data processing is based on our legitimate interest in protecting our website from abusive automated crawling and spam.
How We Use Information
Your information is used to provide and improve the LinkStack service, including:
- Personalizing your public link-in-bio page.
- Facilitating "Business" features and verification badges.
- Providing you with analytics regarding your profile performance.
Data Security
We utilize Supabase's secure infrastructure to manage your data. All authentication and database requests are handled via secure, encrypted channels. We do not sell your personal data to third parties.
Your Rights
You have the right to access, update, or delete your personal information at any time through your dashboard. If you delete your account, all associated profile data and links will be removed from our active databases.
