Privacy Policy

Last updated: March 27, 2026

NIS Tracker ("the App") is operated by the NIS Tracker development team. This policy explains what data we collect and how we use it.

What we collect

• Account info: your name, email address, and password (stored securely via Firebase Authentication).
• Swim data: distance, duration, water temperature, location, date, notes, and tagged swim partners.
• Photos: swim photos you attach to your logs and your profile picture, if you choose to upload them.
• Events: events you create or respond to.
• Device info: basic analytics to help us fix bugs and improve the App (no advertising identifiers).

How we use your data

• To provide the App's core features: your feed, leaderboards, events, and profile.
• To send you notifications you've opted into (e.g., swim reactions, event updates).
• To maintain and improve the App.

What we don't do

• We don't sell your data to anyone.
• We don't share your data with third-party advertisers.
• We don't use your data for profiling or targeted advertising.

Where your data is stored

Your data is stored in Google Firebase (Cloud Firestore, Firebase Authentication, and Firebase Storage for photos), hosted in the EU.

Data retention

Your data is kept as long as you have an active account. If you delete your account, your data is removed. Photos attached to swims are deleted when the swim is deleted or your account is removed.

Your rights

You can request a copy of your data or ask us to delete your account and all associated data by emailing andrew@nistracker.com.

Third-party services

The App uses Firebase (Google) for authentication, data storage, and push notifications. Google's privacy policy applies to their services.

Changes to this policy

We may update this policy. We'll notify you of significant changes through the App.
