Terms of Use — TDY Slayer

1. About these terms

These Terms of Use ("Terms") govern your use of the TDY Slayer mobile application ("TDY Slayer," the "App," "we," "us," or "our"), published by Southwind Digital LLC ("Southwind Digital"). By downloading, installing, or using TDY Slayer you agree to these Terms. If you do not agree, do not use the App.

TDY Slayer is provided to you as a personal productivity tool. It is not affiliated with, endorsed by, or sponsored by the U.S. Department of Defense, the Defense Travel System (DTS), the Defense Travel Management Office (DTMO), the U.S. General Services Administration (GSA), the U.S. Department of the Treasury, or any branch of the U.S. Armed Forces.

2. What TDY Slayer does

TDY Slayer helps you:

Capture photos and PDFs of receipts and other travel documents during official government travel.
Read structured information from those documents using cloud-based AI.
Organize that information by trip so you can prepare a Defense Travel System (DTS) voucher more quickly.
Provide estimates of common travel allowances using publicly available U.S. Government reference data bundled with the App.
Export a summary you can use as a worksheet when entering a voucher into DTS.

TDY Slayer is an organizational aid. It does not submit vouchers to DTS, does not transmit anything to your finance office, and does not communicate with any official government system. You remain solely responsible for accurately entering and submitting your travel voucher in DTS in accordance with the Joint Travel Regulations (JTR), your service's supplemental guidance, and your finance office's instructions.

3. Eligibility

You must be at least 18 years old to use TDY Slayer. By using the App you represent that you have the legal authority to agree to these Terms.

TDY Slayer is designed for use by U.S. military service members, DoD civilians, and other authorized government travelers preparing DTS vouchers. You may use the App in connection with personal travel reimbursement claims (for example, contractor expense reports), but the App's reference data, computations, and copy are tuned for DTS use cases. We make no claim of suitability for any other reimbursement system.

4. Your account and your device

TDY Slayer currently runs locally on your iPhone without a Southwind Digital user account. Your trip data and receipt images are stored on your device in an Apple App Group container that is shared between the App and its Share Extension.

You are responsible for:

Keeping your device secure (passcode, biometric lock, current iOS version).
Backing up your device through iCloud or another method if you want to preserve your data.
Any operational security ("OPSEC") considerations that arise from storing travel patterns, locations, and dates on your device.

If you delete the App, your trip data and receipt images stored locally are deleted with it. We cannot recover them.

5. The OCR service

To read information from receipts, the App sends receipts and other documents to a Cloudflare Worker operated by Southwind Digital, which in turn uses Anthropic's Claude AI. See the Privacy Policy for details on what is sent, how long it is retained, and what protections apply.

The OCR service is provided on a best-effort basis. AI can and does make mistakes. You agree to:

Review every field the App produces from a receipt before relying on it. The App will surface items it thinks need your attention, but the final accuracy is your responsibility.
Verify totals, dates, locations, and other voucher data against the source receipt before entering them in DTS.
Not rely on the App's per-diem, M&IE, mileage, or other travel-allowance estimates as authoritative. They are convenience features for sanity-checking, not official rate authority.

6. Acceptable use

You agree not to:

Use TDY Slayer to prepare any voucher you know or have reason to believe contains false, inflated, or otherwise non-reimbursable claims. False claims against the government may be a federal offense under 18 U.S.C. § 287, the False Claims Act, and the Uniform Code of Military Justice. You bear sole responsibility for the truthfulness of anything you submit to DTS.
Reverse engineer, decompile, or attempt to extract source code from the App, except to the extent applicable law expressly permits.
Interfere with, abuse, or attempt to circumvent the rate limits or authentication on the cloud OCR service.
Use the App in a way that violates the Joint Travel Regulations, your service's supplemental guidance, your command's instructions, or U.S. law.
Use the App to process documents that are classified or otherwise restricted from being processed on a personal commercial device. TDY Slayer runs on commercial cloud infrastructure (Cloudflare and Anthropic) and is not authorized for classified information.

7. Intellectual property

The App, including its code, design, copy, and any proprietary methods used inside it, is owned by Southwind Digital LLC or its licensors and is protected by U.S. and international copyright, trade secret, and other intellectual property laws.

Apple's App Store license terms also apply to your use of the App.

Publicly available U.S. Government reference materials bundled with the App (such as travel regulations and per-diem tables) are works of the U.S. Government and are not copyrighted. They are included for your reference convenience.

8. Your content

Receipts, photos, trip data, personal information, and any other content you create in or import into the App ("Your Content") remain yours. You grant Southwind Digital a limited license to process Your Content solely to provide the App's features (including sending images to the OCR service and storing them locally on your device). We do not claim ownership of Your Content.

9. Disclaimers

TDY Slayer is provided "as is" and "as available" without warranties of any kind. To the maximum extent permitted by law, Southwind Digital disclaims all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.

We do not warrant that:

The App will be uninterrupted, error-free, or available at any particular time.
The OCR results will be accurate, complete, or current.
The travel-allowance or currency-conversion estimates produced by the App will match the figures DTS or your finance office actually applies to your voucher.
The App will be compatible with any particular version of iOS or any particular iPhone model.

You are solely responsible for the contents of any voucher you submit. Reimbursement decisions are made by your finance office under the JTR and your service's regulations, not by Southwind Digital or by this App. If a voucher is rejected, reduced, or audited, that is between you and your finance office.

10. Limitation of liability

To the maximum extent permitted by law, in no event will Southwind Digital LLC, its members, officers, employees, contractors, or affiliates be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, reimbursement, or goodwill, arising out of or related to your use of (or inability to use) the App, even if advised of the possibility of such damages.

Southwind Digital's total cumulative liability arising out of or related to these Terms or the App will not exceed the greater of (a) the amount you paid Southwind Digital for the App in the twelve months preceding the claim, or (b) U.S. $50.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages, so some of the above may not apply to you. In that case, our liability is limited to the smallest extent permitted by applicable law.

11. Indemnification

You agree to indemnify and hold harmless Southwind Digital LLC and its members, officers, employees, contractors, and affiliates from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to (a) your use of the App, (b) Your Content, (c) any voucher you submit in DTS or any other reimbursement system in reliance on the App, or (d) your violation of these Terms or applicable law.

12. Changes to the App and to these Terms

We may update the App from time to time to add features, fix bugs, or maintain compatibility. We may also update these Terms. Material changes will be reflected in the "Last updated" date at the top of this document and, where appropriate, surfaced inside the App. Your continued use of the App after a change becomes effective constitutes acceptance of the updated Terms.

If a change to these Terms is unacceptable to you, your sole remedy is to stop using and uninstall the App.

13. Termination

You may stop using the App at any time by deleting it from your device.

We may suspend or terminate your access to the cloud OCR service (or any future Southwind Digital service) at any time, with or without notice, for any reason, including suspected abuse, suspected fraud, or suspected violation of these Terms.

Sections 7 through 11 and 13 through 16 survive termination.

14. Governing law and disputes

These Terms are governed by the laws of the State of Kansas, without regard to its conflict-of-laws rules. Any dispute arising out of or related to these Terms or the App will be resolved exclusively in the state or federal courts located in Sedgwick County, Kansas, and you consent to the personal jurisdiction of those courts.

Nothing in this section limits any rights you may have under the consumer-protection laws of your state or country that cannot be waived by contract.

15. Apple App Store terms

If you downloaded the App from the Apple App Store, the following also applies:

These Terms are between you and Southwind Digital LLC, not Apple. Apple is not responsible for the App or its contents.
Apple has no obligation to provide maintenance or support for the App.
In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any). To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
Apple is not responsible for addressing any claims by you or any third party related to the App, including product-liability, regulatory-compliance, or intellectual-property claims.
Apple and Apple's subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
