Welcome to Tailwindup. We respect your privacy and are committed to protecting your personal information. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your information.

By using Tailwindup, you agree to the collection and use of information in accordance with this policy. If you do not agree with our policies and practices, do not use our service.

Information We Collect

We collect several types of information to provide and improve our service:

Account Information: When you create an account, we collect your email address and name. This information is necessary to identify you and provide access to your account.

Usage Data: We collect information about your conversions, including the code you convert, conversion formats (CSS, Tailwind, SCSS), and conversion history. This data helps us improve our conversion algorithms and provide you with access to your past conversions.

Technical Data: We automatically collect certain technical information, including your IP address (hashed for rate limiting), browser type, device information, and access times. This data helps us prevent abuse and improve service performance.

Analytics: We use Plausible Analytics, a privacy-friendly analytics service that does not use cookies or collect personal data. Analytics help us understand how users interact with Tailwindup to improve the user experience.

Custom Configurations: If you save custom Tailwind configurations or SCSS variables, we store these securely in your account for future use.

Service Provision: To provide, maintain, and improve the Tailwindup conversion service, including processing your style conversions and managing your account.

Data Security

We take the security of your data seriously and implement appropriate technical and organizational measures:

Encryption: All data transmitted between your browser and our servers is encrypted using TLS (Transport Layer Security). Passwords are hashed using industry-standard bcrypt.

Access Controls: Access to user data is restricted to authorized personnel only and protected by authentication mechanisms.

Infrastructure Security: We rely on Supabase and Vercel's enterprise-grade security infrastructure, which includes regular security audits, monitoring, and compliance certifications.

Data Retention: We retain your account information and conversion history for as long as your account is active or as needed to provide you services. You can request deletion of your data at any time.

While we strive to protect your information, no method of transmission over the internet or electronic storage is 100% secure. We cannot guarantee absolute security.
