Privacy Policy

Last updated: July 3, 2026

Source to Sea: The Nile ("the app") is developed by CharterOne Solutions. This policy explains what data the app collects, how it's used, and how you can control or delete it.

What we collect

• Fitness data: rowing and paddle-sport workout distance, duration, and active energy, read from Apple Health. We never write to Apple Health — read access only.
• Email address: collected via Sign in with Apple, used only for account recovery and support.
• Account identifier: a unique ID tied to your Apple sign-in, used to keep your progress attached to your account.
• Display name and country (optional): if you choose to appear on the public leaderboard, your chosen name, country, and total distance are visible to other users. This is off by default and can be turned off at any time in Profile.

What we don't collect

We do not access your location, contacts, photos, or browsing history. We do not use advertising identifiers, third-party analytics, or ad-network SDKs of any kind. We do not sell or share your data with data brokers or advertisers.

How your data is used

Solely to run the app's core features: tracking your progress along the route, unlocking checkpoints and awards, and the optional public leaderboard. Health data is never used for advertising, marketing, or resold to third parties.

Who we share data with

Your data is stored with Supabase, our backend infrastructure provider, acting solely on our instructions to store and serve your data — not as an independent party using it for their own purposes.

Your control over your data

• Reset progress: wipes your workouts and progress, keeps your account.
• Delete all my data: permanently and immediately deletes every workout, progress record, and correction tied to your account. This cannot be undone. Both are available in Profile at any time.

Children's privacy

This app is not directed at children under 13, and we do not knowingly collect data from children under 13.

Security

Data is protected in transit via HTTPS/TLS and access-controlled so you can only ever see your own data.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected here with an updated date.
