Privacy Policy

Last updated: March 8, 2026

1. Introduction

Monetly ("we", "our", "us") is a Validation Operating System that helps founders and product teams test business ideas through behavioral measurement. This Privacy Policy explains how we collect, use, and protect your information when you use our platform at monetly.io.

2. Information We Collect

We collect the following categories of information:

  • Account Information: Email address provided during authentication via magic link. We do not collect passwords.
  • Workspace & Project Data: Project names, experiment configurations, landing page content, and domain settings you create within the platform.
  • Billing Information: Subscription and payment data is processed by our payment providers (Polar and Stripe). We do not store credit card numbers directly.
  • Usage Analytics: We use PostHog to collect platform usage events (e.g., logins, experiment creation) to improve the product. These are prefixed with app_ and are separate from experiment measurement data.
  • Experiment Measurement Data: When visitors interact with your test landing pages, we collect behavioral events (page views, CTA clicks, email submissions, checkout interactions) to produce validation decisions. These events are prefixed with test_.

3. How We Use Your Information

  • To provide and maintain the Monetly platform
  • To produce BUILD, ITERATE, or KILL decisions based on measured behavior
  • To process subscriptions and manage billing
  • To send transactional emails (via Resend) related to your account
  • To improve platform functionality and user experience
  • To enforce usage quotas based on your subscription plan

4. AI-Generated Content

Monetly uses OpenAI to generate landing page copy for your experiments. The prompts sent to OpenAI include your project description and experiment parameters. OpenAI's data usage policies apply to this processing. Generated copy is stored within your landing page revisions.

5. Payment Intent Mode

The payment intent experiment mode uses a simulated checkout form. No real payment information is collected, processed, or stored. The form measures behavioral intent (willingness to pay) without any financial transaction occurring.

6. Data Storage & Security

Your data is stored in Supabase (PostgreSQL) with Row Level Security (RLS) enabled, ensuring users can only access their own workspace data. We use HTTPS for all data transmission. Metric snapshots and decisions are stored as immutable records.

7. Data Retention

  • Account data: Retained while your account is active
  • Experiment data: Retained for 90 days after experiment conclusion
  • Metric snapshots & decisions: Immutable records retained for the duration of the experiment data retention period
  • Deleted accounts: Data purged within 30 days of account deletion

8. Third-Party Services

We use the following third-party services:

  • Supabase: Database, authentication, and storage
  • Google Analytics (GA4): Website analytics to understand how visitors use Monetly. Data is processed by Google LLC in the United States. Google Analytics only activates after you give explicit consent via our cookie banner. For more information, see Google's Privacy Policy.
  • PostHog: Product analytics and event tracking (activated only with your consent)
  • Polar / Stripe: Payment processing and subscription management
  • Resend: Transactional email delivery
  • OpenAI: AI-powered copy generation
  • Vercel: Application hosting

9. Cookies

We categorize cookies into two groups. You can manage your preferences at any time using the "Cookie Settings" button available on every page.

Essential Cookies (always active):

  • Supabase Auth session cookies — Required for login and authentication. These cannot be disabled.

Analytics Cookies (opt-in only):

  • Google Analytics (_ga, _ga_* cookies, up to 2 years) — Helps us understand page views, navigation patterns, and general usage. Data is sent to Google LLC (US). These cookies are only set after you give explicit consent.
  • PostHog (localStorage-based) — Tracks platform usage events to help us improve the product. Only activated with your explicit consent.

We do not use advertising, marketing, or third-party tracking cookies. You can withdraw your consent at any time by clicking "Cookie Settings" and selecting "Only Necessary". When you withdraw consent, all analytics cookies are immediately deleted.

10. Your Rights

You have the right to:

  • Access your personal data
  • Request correction of inaccurate data
  • Request deletion of your account and associated data
  • Export your experiment data (available on Pro and Advanced plans)
  • Cancel your subscription at any time
  • Withdraw cookie consent at any time via "Cookie Settings"
