Cookie Policy

What cookies MaintlyQR uses and why — essential only, nothing more.

Effective July 2, 2026 · Revised July 2, 2026

1. What Are Cookies

Cookies are small text files placed on your device by a website when you visit it. They are widely used to make websites work efficiently, provide functionality, and give site owners information about how their sites are used.

2. How MaintlyQR Uses Cookies

MaintlyQR uses essential cookies only. We do not use advertising cookies, tracking pixels, social media cookies, or third-party analytics cookies.

Our approach is minimal by design: we collect only what is necessary to operate the Platform and provide you with a secure, functional experience.

3. Cookies We Use

Cookie NameTypePurposeDuration
sb-access-tokenEssentialMaintains your authenticated session (Supabase Auth)Session
sb-refresh-tokenEssentialKeeps you signed in across browser sessions (Supabase Auth)Persistent

These cookies are set by Supabase, our authentication provider. Without them, you cannot log in or remain signed in to the Platform.

4. What We Do NOT Use

MaintlyQR does not use:

  • Google Analytics, Meta Pixel, or any third-party tracking scripts
  • Advertising or retargeting cookies
  • Social media cookies or share buttons that track you
  • Cross-site tracking or fingerprinting technologies
  • Cookies that collect personal data beyond what is needed for authentication

5. Your Choices

Because we use only essential cookies, blocking or deleting them will prevent you from logging in to the Platform. You can manage cookies through your browser settings, but note that disabling essential cookies will break authentication.

If you access public QR pages without logging in, no cookies are required and none are set.

6. Third-Party Providers

Our authentication cookies are managed by Supabase. Supabase's privacy policy is available at supabase.com/privacy. We host the Platform via Vercel, which may set technical cookies for load balancing and performance purposes.

7. Changes to This Policy

We may update this Cookie Policy from time to time. If we introduce any new types of cookies, we will update this policy and notify registered users. Continued use of the Platform after changes take effect constitutes acceptance.
