Privacy Policy

Last updated: March 2026

Tendril respects your privacy. This Privacy Policy explains what data we collect, how we use it, and your rights.


Information we collect

We collect only the data required to operate the service.

When you sign up, we collect:

  • Email address
  • Stripe customer ID (if you subscribe to Pro)
  • Affiliate code (if you join the affiliate program)

Authentication is handled using one-time login codes sent to your email. We do not use passwords.

Waitlist data

When you create a waitlist or when someone joins your waitlist, we may store:

  • Email addresses submitted to your waitlist
  • Basic usage data (such as views, signups, and clicks)

Technical data

We use essential cookies to keep you signed in and operate the service. These cookies are required and cannot be disabled. We also use the Endorsely tracking script for affiliate referrals. We do not use advertising or tracking cookies.

Analytics

We use Plausible Analytics, a privacy-friendly, cookie-less analytics service. Plausible does not track individuals, does not use cookies, and is GDPR compliant. All data is anonymized and aggregated.

Payment processing

If you subscribe to Tendril Pro, payment processing is handled by Stripe. We store your Stripe customer ID to manage your subscription. We do not store your payment card details - these are securely handled by Stripe.

Affiliate program

Tendril offers an optional affiliate program powered by Endorsely. If you join the program, your affiliate code and earnings data are stored. Commission tracking is handled by Endorsely and Stripe.
