By downloading, installing, or using Southbound ("the App"), you agree to these Terms of Service. If you do not agree, do not use the App.
Southbound is an iOS application that uses location services to track the number of days you spend in the state of Florida. The App is designed to help users document their physical presence for tax residency purposes.
Southbound is a tracking and documentation tool only. The App does not provide tax advice, legal advice, or professional guidance of any kind. Tax residency rules vary by state and are subject to change. You should consult a qualified tax professional or attorney for advice specific to your situation.
Southbound makes no guarantee that its reports will satisfy the requirements of any tax authority, court, or government agency. The App is intended to supplement, not replace, professional tax documentation.
Southbound relies on iOS location services, which have inherent limitations. GPS accuracy varies based on device, environment, and signal conditions. The App uses iOS significant location changes, which may not capture every state border crossing instantly. Manual overrides are available to correct any inaccuracies.
We strive for accuracy but do not guarantee that location determinations will be 100% correct at all times.
During the early access period, Southbound is provided free of charge via Apple TestFlight. Early access software may contain bugs, inaccuracies, or incomplete features. By participating, you acknowledge that:
After the early access period, Southbound will be available as a paid subscription at $249/year, billed annually through the Apple App Store. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing period. You can manage or cancel your subscription in your Apple ID settings.
All data generated by Southbound is stored locally on your device and backed up to your personal iCloud account via Apple's CloudKit. You own your data. We do not have access to it, cannot recover it from our end, and are not responsible for its loss. iCloud backup provides protection against device loss or replacement.
We recommend using the export feature regularly to maintain an independent backup of your records. You can manage your iCloud data through your Apple ID settings.
You agree not to:
To the maximum extent permitted by law, Southbound and its creators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to: loss of data, tax penalties, fines, or adverse tax determinations arising from use of the App.
The App is provided "as is" without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
You may stop using the App at any time by uninstalling it. We reserve the right to terminate or suspend access to the App at our discretion, particularly in cases of Terms violations.
We may update these terms from time to time. Changes will be posted on this page with an updated revision date. Continued use of the App after changes constitutes acceptance of the revised terms.
These terms are governed by the laws of the State of Florida, without regard to conflict of law provisions.
