Privacy Policy

Last updated July 2, 2026

Tailwaters is a mobile fly-fishing app for Arkansas tailwaters. This Privacy Policy describes the app and website as currently implemented.

Information You Provide

• Email/password accounts: If you create an account with email and password, Supabase Auth processes your email address, password credential, session tokens, password reset requests, and related account metadata.
• Social sign-in: If you sign in with Google, Apple, or Facebook, Tailwaters uses Supabase Auth with the identity provider's token flow. Apple sign-in requests email and full name; Apple may provide the name only the first time you authorize the app, and Tailwaters stores the returned name in Supabase user metadata when available.
• Support messages: If you email us, we receive the contact information and content you choose to send.

Location

Tailwaters requests foreground location permission only. Android declares coarse and fine location permissions; iOS uses when-in-use location copy. The app uses phone GPS through the operating system and the Geolocator library to calculate your miles below the selected dam, show your position relative to river access points, and support river safety context while the app is open.

Tailwaters currently processes phone GPS coordinates on the device for river-position calculations and does not send raw phone GPS coordinates to Supabase product tables. Google Maps SDKs may process map viewport, marker, and related map interaction data when map screens or the manual location picker are displayed. Manual river spot selections are currently in-memory for the app session. Your selected dam is stored locally on your device with SharedPreferences.

Telemetry and Diagnostics

Tailwaters uses an app-owned telemetry layer with Firebase as the current remote telemetry provider. In release builds, Firebase Analytics, Crashlytics, and Performance Monitoring may collect app events, crash diagnostics, performance information, device model, operating system version, app version, timestamps, and related technical data. App code disables Firebase Analytics, Crashlytics, and Performance collection outside release builds.

Tailwaters does not currently use advertising SDKs, payment SDKs, in-app purchase processing, contacts access, camera access, microphone access, or background location tracking.

Website

The Tailwaters website, including this page, is hosted on Firebase Hosting. We do not currently add web analytics, advertising pixels, or cookies to the static website. Firebase Hosting and related infrastructure may process standard request information such as IP address, browser user agent, request URL, and timestamps to serve and secure the website.

Third-Party Services

• Supabase: Authentication, sessions, password reset, account metadata, and the delete-account Edge Function.
• Google: Google sign-in, Google Maps SDKs, Google Play distribution, and Firebase services including Hosting, Analytics, Crashlytics, and Performance Monitoring.
• Apple: Sign in with Apple and App Store distribution.
• Meta/Facebook: Facebook OAuth sign-in if you choose that provider.
• External websites: In-app reference links may open public resources such as AGFC, USACE, USGS, National Weather Service, Google Drive-hosted documents, and Wikimedia-hosted images in platform browser sheets or your browser.

How We Use Information

• Authenticate users, maintain sessions, and support password reset and account deletion.
• Show Tailwaters content for the selected dam and, with permission, for your current or manually selected river position.
• Operate maps, legal links, public reference links, and app store links.
• Monitor reliability, diagnose crashes, and improve app performance and usability.
• Respond to support requests, prevent misuse, and comply with legal obligations.

Sharing

We do not sell personal information. We share information with service providers as needed to operate Tailwaters, when required by law, to protect users or the app, or as part of a business transfer such as a merger or acquisition.

Retention and Deletion

We keep account information as long as needed to provide Tailwaters, comply with legal obligations, resolve disputes, and enforce agreements. If you delete your account in the app, Tailwaters calls a Supabase Edge Function that verifies your active session and deletes your Supabase Auth user. Some logs, analytics, crash reports, backups, or provider records may remain for a limited time according to operational, legal, security, or provider retention practices.

Your Choices

• You can deny or revoke location permission in your device settings. The app can still use a default or manually selected river spot.
• You can sign out or delete your account from the in-app account menu.
• You can choose whether to use email/password, Google, Apple, or Facebook sign-in where available.
• You can avoid opening third-party reference links if you do not want those sites to receive browser request information.

Children

Tailwaters is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

Changes

We may update this Privacy Policy from time to time. If we make material changes, we will update the date above and provide any additional notice required by law.
