When you connect advertising platform accounts to Zellify, we access and collect data from those platforms via their APIs. The data collected varies by platform but generally includes:

  • Account information: Ad account name, ID, status, and associated business details.
  • Campaign data: Campaign names, objectives, statuses, budgets, schedules, and bid strategies.
  • Ad set / ad group data: Targeting settings (demographics, interests, behaviors, locations, custom audiences), placements, optimisation goals, and delivery status.
  • Ad data: Ad creatives (images, videos, copy, headlines, descriptions), format, preview links, and status.
  • Performance metrics: Impressions, reach, clicks, click-through rates, conversions, cost-per-result, return on ad spend (ROAS), frequency, and other reporting metrics.
  • Audience data: Custom audience names, sizes, and types (excluding the underlying user-level data within those audiences).

Meta (Facebook / Instagram): We access data through the Meta Marketing API with the following permissions: ads_read, ads_management, business_management, pages_show_list, pages_read_engagement, and public_profile, as well as Ads Management Standard Access.

TikTok Ads: We access campaign, ad group, ad, and performance data through the TikTok Marketing API.

Google Ads: We access campaign and performance data through Google's advertising APIs.

1.6 Attribution Data We Send to Platforms

Zellify sends real-time conversion and attribution events (such as sign-ups, purchases, and subscription events) from your published funnels back to your connected advertising platforms. This allows the platforms to optimise ad delivery and accurately report on campaign performance. Data sent may include event type, event time, transaction value, and anonymised user identifiers. This data flows to:

  • Meta via the Conversions API (CAPI).
  • TikTok via the TikTok Events API.
  • Google via Google Analytics / Google Tag Manager.

1.7 End User Data (Funnel Visitors)

When end users interact with funnels you have published through Zellify, we collect data on your behalf as a data processor. This may include:

  • Form and quiz responses: Answers, selections, and inputs provided by end users during funnel flows.
  • Device and browser data: IP address, browser type, operating system, screen resolution, and referring URL.
  • Funnel interaction data: Pages viewed, drop-off points, time on page, and button clicks.
  • Payment data: When end users make purchases through your funnels, payment is processed by your connected Stripe or Paddle account. Zellify receives transaction confirmation data (amount, currency, subscription status) but does not receive or store full payment card details of your end users.

You, as the funnel owner, are the data controller for this end user data. You are responsible for providing appropriate privacy disclosures and obtaining any necessary consents from your end users.

1.8 Data Collected via Cookies and Tracking

See Section 8 — Cookies and Tracking Technologies for details on data collected through cookies, Google Analytics, and PostHog.

4. Meta Platform Data — Special Provisions

This section specifically addresses data collected from the Meta platform in accordance with Meta's Platform Terms and Developer Policies.

4.1 What We Do with Meta Data

We use data obtained from the Meta Marketing API to:

We use Anthropic's Claude AI models to analyse your Meta advertising data and provide insights, recommendations, and summaries. When your data is sent to Anthropic for processing:

  • Data is transmitted securely via encrypted connections.
  • Anthropic processes the data solely to generate responses for your use within Zellify.
  • We do not permit Anthropic to use your data to train their AI models.
  • Only aggregated campaign and performance data is sent — we do not send personal information of individuals within your audiences.

4.3 Data Storage and Retention

  • Meta platform data is stored on our servers to provide the Service.
  • Some data is fetched and displayed in real time directly from Meta's API; other data is cached or stored to enable historical analysis and reporting.
  • Meta data is retained for as long as your account is active and your Meta account remains connected, unless you request deletion (see Section 7).
  • When you disconnect your Meta account from Zellify, we stop fetching new data from Meta. Previously stored data is retained until you request its deletion.

4.4 No Sale of Meta Data

  • Additional technical and organisational measures where necessary (e.g., encryption in transit and at rest).

10. HIPAA Compliance

Zellify is compliant with the Health Insurance Portability and Accountability Act (HIPAA). We maintain administrative, physical, and technical safeguards to protect electronic protected health information (ePHI) in accordance with the HIPAA Security Rule and Privacy Rule.

10.1 Safeguards

Our HIPAA compliance programme includes 74 security controls spanning:

  • Administrative safeguards: Information security policies, security roles and responsibilities, workforce training (including ePHI privacy training), incident response procedures, and risk management with annual risk assessments.

  • Technical safeguards: Encryption at rest and in transit, multi-factor authentication, production access management, intrusion detection, centralized log collection and monitoring, vulnerability scanning, and web application firewall protection.

10.2 Business Associate Agreements

Where third-party processors handle ePHI on our behalf, we enter into Business Associate Agreements (BAAs) that require them to implement appropriate safeguards, report breaches within required timelines, and comply with HIPAA requirements.

10.3 Breach Notification

In the event of a breach of unsecured ePHI, we will notify affected individuals, the U.S. Department of Health and Human Services, and (where applicable) the media, in accordance with the HIPAA Breach Notification Rule.

We implement comprehensive technical and organisational measures to protect your personal data, maintained and monitored through our compliance programme:

  • Encryption: All data is encrypted at rest and in transit (TLS 1.2+). Production encryption keys are managed through secure key management practices.
  • Authentication: Multi-factor authentication is enforced for production systems. Password policies and infrastructure authentication controls are in place.
  • Access control: Production access is restricted on a need-to-know basis, with quarterly access reviews and immediate revocation upon termination.
  • Monitoring: Centralized log collection, login attempt monitoring, intrusion detection systems, and continuous capacity and performance monitoring.
  • Secure development: Source code access controls, code change approval processes, environment separation, and secure development procedures.
  • Vulnerability management: Regular vulnerability scanning and remediation, patch management, and periodic penetration testing.
  • Network security: Firewall rule management, secure connection requirements, and web application firewall (WAF) protection.
  • Endpoint security: Anti-malware protection, removable media controls, and secure workstation configuration.
  • Incident response: Documented incident response procedures, security incident logging, and breach notification processes.
  • Personnel: Employee background checks, confidentiality agreements, security awareness training, and a documented disciplinary process.

Meta API access tokens are stored securely and encrypted. All credentials and secrets are managed through secure storage mechanisms.

While we strive to protect your data, no method of electronic storage or transmission is 100% secure. If you discover a security vulnerability, please report it to [email protected].
