Privacy Policy

Last updated: April 2026

At Fathom Blue, we believe your privacy is as important as the ocean is deep. This Privacy Policy explains how we collect, use, and protect your personal information when you use the Fathom Blue app and website (www.fathomblueco.com).

1. Information We Collect

Information You Provide

  • Email address — collected when you join our waitlist or create an account.
  • Training data — breath-hold times, session logs, and personal bests that you record in the app.
  • Account details — name and profile preferences if you create an account.

Information Collected Automatically

  • Usage data — anonymous information about how you use the app and website (pages visited, features used, session duration).
  • Device information — device type, operating system version, and app version for bug fixing and improvement.
  • Crash reports — anonymised crash data to help us fix issues quickly.

2. How We Use Your Data

We use the information we collect to:

  • Operate and improve the Fathom Blue app and website.
  • Send you launch notifications and app updates (waitlist emails only).
  • Provide customer support when you contact us.

  • Analyse usage trends to develop new features ocean athletes actually want.
  • Comply with legal obligations.

3. Third-Party Services

We use the following trusted third-party services to operate Fathom Blue:

  • Supabase — database and authentication. Your email and training data is stored securely on Supabase servers.
  • RevenueCat — subscription management and in-app purchase processing via Apple and Google. We do not store your payment details.
  • AdMob (Google) — advertising on the free tier of the app. AdMob may use your device identifier to serve relevant ads.
  • Apple App Store / Google Play — app distribution. Their respective privacy policies apply to any purchases made through their stores.
  • Vercel — website hosting and delivery.

Each of these services has its own privacy policy. We select partners who meet high standards for data security.

4. Data Sharing

We never sell your personal data to third parties. Full stop.

We may share data in the following limited circumstances:

  • With our service providers listed above, only to the extent necessary to operate the service.
  • If required by law, court order, or regulatory authority.
  • In the event of a merger or acquisition, with your rights protected under this policy.

5. Data Retention

We retain your data for as long as your account is active or as needed to provide our services. If you request deletion, we will remove your personal data within 30 days, except where retention is required by law.

6. Your Rights

Depending on your location, you may have the right to:

  • Access the personal data we hold about you.
  • Correct inaccurate data.
  • Request deletion of your data.
  • Object to or restrict processing of your data.
  • Data portability — receive your data in a machine-readable format.
  • Withdraw consent at any time (where processing is based on consent).

To exercise any of these rights, contact us at hello@fathomblueco.com. We will respond within 30 days.

7. Cookies

Our website uses minimal session cookies only — strictly necessary for the site to function. We do not use tracking cookies or advertising cookies on our website. You can disable cookies in your browser settings, though this may affect site functionality.

8. Children's Privacy

Fathom Blue is intended for users aged 18 and over (or 13+ with verifiable parental consent where applicable). We do not knowingly collect personal data from children under 13. If you believe we have inadvertently collected such data, please contact us immediately.

9. Data Security

We use industry-standard security measures including encryption in transit (TLS) and at rest, access controls, and regular security reviews. However, no method of transmission or storage is 100% secure — we encourage you to use a strong, unique password.

10. International Transfers

Fathom Blue operates globally. Your data may be processed in countries other than your own. Where we transfer data internationally, we ensure appropriate safeguards are in place in accordance with applicable data protection law.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify waitlist and registered users of material changes by email. The date at the top of this page will always reflect the most recent update.
