Effective July 17, 2026 · Flowy is published by Snoflo.org LLC ("Snoflo," "we," "us"). By purchasing, downloading, or using Flowy you agree to these terms.

1. Informational use only. Flowy presents hydrological and environmental data (streamflow, gage height, water temperature, weather, and user-submitted observations) for general informational and recreational-planning purposes only. It is not a safety device, navigation aid, forecast service, or emergency information source, and it is not professional, engineering, or safety advice.
2. Data is provisional and third-party. Gauge readings and related data originate from third-party sources, including the U.S. Geological Survey and other public feeds, and are typically provisional, subject to revision, delay, gaps, and error. Community reports are subjective observations by anonymous users. Snoflo does not originate, verify the accuracy of, or warrant any of this data, and readings shown in Flowy may differ from official records.
3. Rivers are dangerous. Use at your own risk. Water conditions change rapidly and without warning. You are solely responsible for your own safety and for independently verifying conditions — including against official sources such as waterdata.usgs.gov and National Weather Service advisories — before entering, crossing, boating, wading, or otherwise engaging with any waterway. You assume all risk arising from river-related activities and from any reliance on the app's content.
4. No warranty. Flowy is provided "as is" and "as available" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, availability, and non-infringement. We do not warrant that the app will be uninterrupted, timely, or error-free.
5. Limitation of liability. To the maximum extent permitted by law, Snoflo.org LLC, its members, officers, and suppliers shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for personal injury, death, property damage, or economic loss, arising from or related to the app or reliance on its content. Our total aggregate liability for any claim shall not exceed the amount you paid for the app.
6. Community reports. By submitting a report you grant Snoflo a perpetual, worldwide, royalty-free license to display and distribute it in anonymous form. You agree to submit only truthful observations from your actual location. We may remove any report and may restrict submissions from any installation at our sole discretion.
7. Acceptable use. You may not misuse the app, including submitting false reports, probing or disrupting our services, scraping data at scale, or reverse-engineering the app except as permitted by law.
8. Indemnification. You agree to indemnify and hold Snoflo harmless from claims arising out of your use of the app, your violation of these terms, or your river-related activities.
9. Changes. We may update the app, these terms, or discontinue features at any time. Continued use after changes constitutes acceptance. Purchases are handled by Apple; refunds are governed by Apple's App Store terms.
10. Governing law. These terms are governed by the laws of the state in which Snoflo.org LLC is organized, without regard to conflict-of-law principles. If any provision is held unenforceable, the remainder stays in effect.

Effective July 17, 2026 · Applies to the Flowy iOS app.

1. No accounts, no tracking. Flowy has no user accounts, no advertising, no analytics SDKs, and no cross-app tracking. We do not sell or share personal data with third parties for marketing.
2. Location. Your location is used on your device to center the map and show nearby gauges. When you submit a report, your coordinates are sent once, over an encrypted connection, solely to verify you are within roughly 100 feet of a river or gauge and to determine current weather. Your exact coordinates are then discarded and are never stored; the published report contains only a randomly offset point several hundred feet away. We never access location in the background.
3. Anonymous install ID. The app generates a random identifier on first launch, stored only on your device and sent with reports for rate-limiting and to let you delete your own reports. It is not linked to your name, email, or any account, and we make no attempt to associate it with your identity.
4. Reports. Published reports contain: an offset location, the condition words you chose, a timestamp, the associated river or gauge name, and the weather at submission time. They are shown publicly and anonymously for 24 hours on the live map. You can delete your own reports from your in-app logbook at any time; your logbook itself is stored only on your device.
5. Email (optional). If you choose to sign up for updates, we store the email address you provide and use it only to send occasional product news. Unsubscribe anytime; write to info@snoflo.org to have your address removed.
6. Feedback (optional). In-app feedback is transmitted with your install ID so we can investigate issues; it contains no identity information unless you include it yourself.
7. Service providers. Map tiles are served by Mapbox, whose servers receive standard network request data (such as IP address) needed to deliver tiles. Weather context is retrieved from a weather data provider using approximate coordinates. Neither receives your identity from us.
8. Retention. Reports persist in our database in anonymous form to support historical condition views. Signup emails are kept until you unsubscribe. Server logs are retained briefly for security and debugging.
9. Children. Flowy is not directed at children under 13 and we do not knowingly collect personal information from them.
10. Contact. Privacy questions: info@snoflo.org.
