Terms of Service

Last updated July 2, 2026

These Terms of Service govern your access to and use of Tailwaters. By using Tailwaters, you agree to these Terms.

Use of Tailwaters

Tailwaters provides fly-fishing, river, dam, map, weather, and safety-context information for planning and general awareness. You are responsible for your own judgment, safety, equipment, travel decisions, and compliance with laws, regulations, posted notices, and local conditions.

Safety Information

Tailwater rivers and hydropower releases can change quickly. Tailwaters may display generated, estimated, public-source, third-party, delayed, incomplete, or illustrative information. The app is not an official warning system and is not a substitute for emergency services, dam operators, official agency notices, posted signage, local guides, personal observation, or conservative river judgment.

Do not rely on Tailwaters as your only source of safety information. If conditions look unsafe, leave the water and follow official instructions.

Accounts and Authentication

You may need an account to use some features. Tailwaters currently uses Supabase Auth for email/password sign-up, sign-in, password reset, sessions, and account deletion. It also supports Google sign-in, Sign in with Apple, and Facebook OAuth where available. You are responsible for maintaining the confidentiality of your credentials and for activity under your account.

Location and Maps

Tailwaters can use foreground device location to estimate your river position and can also use a manually selected river spot. Location-derived labels, map markers, access points, route lines, distance calculations, and safety context are approximate and may be wrong. You must verify your actual position and conditions before making fishing, boating, or wading decisions.

Third-Party Services and Content

Tailwaters uses third-party services and SDKs to operate the app and website, including Supabase, Firebase, Google Maps, Google sign-in, Sign in with Apple, Facebook OAuth, App Store distribution, Google Play distribution, Geolocator/operating-system location services, SharedPreferences/local device storage, Flutter Custom Tabs, and iOS Safari view controller browser sheets.

The app may link to or display reference material from third-party or public sources such as AGFC, USACE, USGS, National Weather Service, Google Drive-hosted documents, and Wikimedia-hosted images. We do not control and are not responsible for third-party services, maps, app stores, identity providers, public data sources, linked websites, availability, accuracy, or content.

Account Deletion

The in-app account menu includes account deletion. The current implementation calls a Supabase Edge Function, verifies your active session, deletes your Supabase Auth user, and signs you out. Deletion may not immediately remove operational logs, analytics, crash reports, backups, provider records, or information that must be retained for legal, security, or operational reasons.

Acceptable Use

You agree not to misuse Tailwaters, interfere with the app's operation, attempt unauthorized access, scrape or overload services, bypass security controls, reverse engineer non-open-source portions of the app, misrepresent your identity, or use the app in a way that violates applicable law or infringes the rights of others.

Intellectual Property

Tailwaters, including its name, branding, design, app experience, and original content, is owned by us or our licensors. App store badges, maps, public-source material, and third-party logos, data, and services remain the property of their respective owners. You may not copy, distribute, modify, or create derivative works from Tailwaters except as allowed by law or with our written permission.

Disclaimer

Tailwaters is provided "as is" and "as available" without warranties of any kind, whether express or implied. We do not guarantee that the app, website, maps, account system, telemetry, links, data, forecasts, generated readings, safety context, or third-party services will be uninterrupted, secure, accurate, complete, current, or available at any particular time.

Limitation of Liability

To the fullest extent permitted by law, we will not be liable for indirect, incidental, consequential, special, exemplary, or punitive damages, personal injury, property damage, lost profits, lost data, loss of goodwill, or other losses arising from your use of or reliance on Tailwaters.

Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will update the date above and provide any additional notice required by law. Continued use of Tailwaters after changes take effect means you accept the updated Terms.
