Privacy policy.

Effective date: 1.1.2025

Ferrivia ("we", "us", or "our") is operated by Powerfuel -ravitsemuspalvelut (Y-tunnus: 2819206-7), a Finnish company. "Ferrivia" is a brand name under which we currently operate and may become a separate legal entity in the future. This Privacy Policy describes how we collect, use, and protect your personal data when you use our digital service.

Ferrivia provides a browser-based web application to help users track and reflect on their iron-related wellbeing. The service includes symptom and lab tracking tools, educational insights, and optional expert feedback. We do not provide medical advice, diagnosis, or treatment.

By using Ferrivia, you agree to this Privacy Policy.

1. What Data We Collect

We collect the following types of data from users:

  • Personal identifiers: Name, email address, age, gender (optional), and other onboarding responses

  • Health-related inputs: Symptom logs, supplement usage, past lab results

  • Usage data: Information on how you use the app (e.g., pages visited, time of use)

  • Device data: Browser type, operating system, language preferences, and IP address

You provide most of this information directly. Some usage and technical data may be collected automatically to improve the service.

2. How We Use Your Data

We use your data for the following purposes:

  • To provide and maintain the service

  • To help you track your own wellbeing over time

  • To generate educational insights (non-medical)

  • To support customer service requests

  • To analyze aggregate trends and improve our offering

  • To communicate with you regarding the service

We do not:

  • Use your data for advertising or marketing

  • Share your personal data with any third parties

  • Use your data for profiling or automated decision-making

We may use anonymized and aggregated data (e.g., "38% of users report cold feet") for educational, research, or marketing purposes, but never in a way that identifies you.

3. Who Has Access to Your Data

Your data is only accessible to the internal Ferrivia team (Powerfuel -ravitsemuspalvelut), specifically those who need it to support the service.

We do not share, sell, or disclose your data to third parties.

4. About Glide (App Platform)

Ferrivia uses Glide to power its browser-based web app. While the app may look and function like a mobile application when saved to a user’s home screen, it runs in a web browser and does not require installation via the App Store or Google Play.

Glide acts as a data processor under the EU General Data Protection Regulation (GDPR), while Ferrivia remains the data controller. This means we decide how and why your personal data is used, and Glide processes it on our behalf.

According to Glide’s GDPR compliance information, the platform:

  • Is fully GDPR compliant

  • Offers a signed Data Processing Agreement (DPA)

  • Provides SOC 2 Type II certified security controls

  • Enables data export and deletion

  • Does not access or use user data for its own purposes

5. Data Retention

We keep your personal data only as long as necessary to provide the service, comply with legal obligations, or support your user experience.

You may request deletion of your account and associated data at any time by contacting us at info@ferrivia.ai.

6. Your Rights

Under the GDPR, you have the right to:

  • Access the personal data we hold about you

  • Correct inaccurate information

  • Request deletion of your data

  • Object to or restrict certain processing

  • Request a copy of your data (data portability)

You can exercise these rights by contacting us at info@ferrivia.ai.

7. Children

Ferrivia is not intended for children under 18 years of age. We do not knowingly collect data from individuals under 18.

8. Data Security

We use industry-standard technical and organizational measures to protect your data. Access to personal data is limited to authorized team members.

9. Changes to This Policy

We may update this Privacy Policy. When we do, we will update the "Effective Date" and notify users via email or in-app notice where appropriate.
