9. Data Security
We implement industry-standard security measures to protect your information:

10. California Privacy Rights (CCPA)
If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA):
- Right to know what personal information we collect and how it's used
- Right to delete your personal information
- Right to opt-out of the sale or sharing of personal information. We do not sell personal information for financial consideration, but our use of the Meta Pixel and Conversions API may constitute “sharing” for cross-context behavioral advertising under CCPA/CPRA. Opt out at Do Not Sell or Share My Personal Information
- Right to non-discrimination for exercising your privacy rights
11. European Privacy Rights (GDPR)
If you are in the European Economic Area (EEA), we process your data under the following legal bases:
- Contract performance: Processing necessary to provide the Service you subscribed to
- Legitimate interest: Analytics, security, fraud prevention, and service improvement
- Consent: Marketing emails, analytics and advertising cookies (Meta Pixel / Conversions API), and other optional data processing. Consent is opt-in for EEA, UK, Swiss, and Canadian users via our consent banner, and is withdrawable at any time via Cookie Preferences
- Legal obligation: Tax records, compliance with legal requests
You have the right to lodge a complaint with your local data protection authority.
12. Analytics & Advertising (Meta Pixel + Conversions API)
We use Meta's advertising tools to measure the performance of our marketing and the paths visitors take through our site:
- Meta Pixel (browser): A small JavaScript snippet that sets the
_fbp and, on ad clicks, _fbc cookies. It reports page views, clicks on pricing tier buttons (InitiateCheckout), and signup completion (CompleteRegistration) to Meta. - Meta Conversions API (server): The same events are also sent directly from our servers for better attribution accuracy. Server-side events include your hashed email, hashed first/last name, hashed internal user ID, IP address, user agent, and the page URL. Hashing uses SHA-256 and is performed before the data leaves our servers.
When these tools fire:
- Visitors from the EEA, United Kingdom, Switzerland, and Canada see a consent banner and the Pixel fires only after affirmative acceptance
- Visitors elsewhere have the Pixel enabled by default, and may opt out at any time at Do Not Sell or Share My Personal Information or Cookie Preferences
- Opting out sets a cookie that disables both the browser Pixel and any server-side Conversions API events tied to your browser. It does not affect your account, session history, or access to the Service
Meta's processing of this data is governed by Meta's own privacy policy, available at facebook.com/privacy/policy.
13. Credential Sharing Detection
To protect the integrity of our subscription model, we monitor for credential sharing by tracking:
- Number of unique devices accessing your account
- IP addresses used during sessions
- Simultaneous session detection
This monitoring is conducted automatically. If anomalous activity is detected, we may contact you for verification or restrict account access. Device fingerprints are hashed and cannot be used to identify you personally.
14. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Material changes will be communicated via email or prominent notice on the Service at least 30 days before taking effect. The “Last updated” date at the top will be revised accordingly.
