Privacy Policy

This Privacy Policy describes how RatioLens ("we", "us", or "our") collects, uses, and shares information about you when you use our website at ratiolens.io.

Information We Collect

We collect information you provide directly to us, including your email address when you create an account. If you subscribe to a paid plan, your payment is processed by Stripe and we do not store your payment card details.

We automatically collect certain information when you use our service, including your IP address, browser type, pages visited, and actions taken within the app. We use this information to improve our service and diagnose technical issues.

How We Use Your Information

We use your information to provide and improve the RatioLens service, send you email alerts and weekly digests you have opted into, process payments and manage your subscription, and communicate with you about your account.

We do not sell your personal information to third parties. We do not use your data to serve advertising.

Email Communications

If you subscribe to Signals or Pro, you may receive email alerts and weekly signal digests. You can manage your email preferences from your account settings or unsubscribe using the link in any email we send.
