Privacy Policy

1. Who we are

Velocity Sprint ("the App", "we", "us") is operated by SFEC, Inc., 4234 SW 75th Ave, Miami, FL 33155, USA. Contact us with the Report an issue button in Contact below, or in the app under Settings → Feedback.

2. What the App touches, and where it stays

• Camera. The App uses your phone's camera as a motion tripwire to detect a runner crossing a line. Frames are analyzed in real time on the device and are not recorded, stored, or transmitted. Nothing from the camera leaves the phone. You can revoke camera access at any time in your browser or phone settings.
• Athlete roster and results. Names, bib numbers, times, splits, notes, workouts, and settings you enter are stored only in your browser's local storage on that phone (key gatesync:v1). We cannot see this data. It is deleted when you use "Erase all data" in Settings or clear the site's data in your browser.
• Timing messages between phones. During a session, phones exchange small timing messages (clock sync, arm, start, crossing events, and a result record including the athlete's name as entered) directly with each other over an encrypted peer-to-peer connection (WebRTC). These messages are not routed through our servers.
• Your account. To run a subscription we store on our servers: your name, email, mobile number, the sport you train, the age range and gender of the athletes you coach, your subscription status, and a record of the phone signed in to your account (device type, approximate region from your network address, and time). We use your mobile number to reach you about your account; we only send tips or marketing texts if you ticked that box at sign-up, and you can reply STOP at any time. Payment cards are handled by Stripe; we never see or store your card number. Athlete names and times stay on your phone as described above. To delete your account, use Settings → Feedback → Report a problem (or email us); we remove this data within 30 days.

3. Third parties that may receive data

We do not sell, rent, or share personal data for advertising. The following service providers process the limited technical data needed to deliver the App:

• PeerJS signaling broker (peerjs.com). To connect two phones, each phone registers a short random pairing ID with the PeerJS public broker. The broker sees your IP address and the pairing ID, which it uses only to introduce the phones to each other. Once paired, timing traffic flows phone-to-phone. Hosted by the PeerJS project; see peerjs.com/privacy.
• Netlify. The App is hosted on Netlify, which keeps standard web-server access logs (IP address, user agent, pages requested) for security and operations, retained for a limited period. See Netlify's privacy policy. If you submit a diagnostics report (below), Netlify Forms stores that submission and emails it to us.
• Supabase. Hosts our account database and sign-in service (email codes and passkeys). It stores the account data listed above and your sign-in sessions. See Supabase's privacy policy.
• Stripe. Processes payments and hosts the checkout and billing pages. Stripe receives your name, email, and card details directly; we receive only the last four digits and your subscription status. See Stripe's privacy policy.
• Resend. Sends our account emails (sign-in security alerts and your subscription confirmation). It sees your email address and the message content. See Resend's privacy policy.

We do not use Google Analytics, advertising pixels, or tracking cookies. The App sets no cookies.

4. Diagnostics reports you choose to send

Settings → Field diagnostics lets you send a technical report to us to help fix field problems. A report contains: app version, phone model and browser (user agent), camera frame timing, detection threshold values, clock-sync statistics, connection events, a shortened session ID, and an optional note you type. Athlete names and results are excluded from diagnostics reports. Reports are sent only when you tap the button, are received by email at our contact address, and are kept only as long as needed to investigate the issue. You may also export the same report as a file instead of sending it.

5. Backups and exports

JSON backups and CSV exports are generated on your phone and saved or shared wherever you choose (Files, AirDrop, email, etc.). Those destinations are outside our control. A backup contains your full roster and results, so treat it as personal data.

6. Children and athlete consent

The App is a tool for coaches, trainers, parents, and athletes. Coaches commonly time athletes under 18. Because all athlete data stays on the coach's phone and is never collected by us, the coach (or the organization the coach works for) is the data controller for that roster and is responsible for obtaining any consent their league, school, or local law requires before recording a minor's name and performance. We do not knowingly collect personal information from children under 13; if you believe a child has sent us personal information (for example in a diagnostics note), contact us and we will delete it.

7. Artificial intelligence

The App does not use artificial intelligence or machine-learning services, and does not send your data to any AI provider. Motion detection is a fixed, on-device image-difference algorithm.

8. Your rights

Because your data lives on your own phone, you control it directly: view it in the App, export it, or erase it at any time. If you are in the EU/UK, California, or another jurisdiction with data-protection rights, you may also contact us to access, correct, or delete any information we hold about you (in practice, only diagnostics reports or emails you sent us). We will respond within 30 days. We do not sell personal information and do not discriminate for exercising your rights.

9. Security

The App is served over HTTPS with a restrictive content-security policy. Peer-to-peer connections use WebRTC's built-in DTLS encryption. Local storage is protected by your phone's own lock screen and browser sandbox — lock your phone and do not share backups you would not want others to read.

10. Changes

We will post any changes here and update the effective date above. Material changes will also be noted in the App's Settings tab.

Terms of Use

1. Acceptance

By using Velocity Sprint you agree to these Terms and to the Privacy Policy above. If you use the App on behalf of a team, school, or organization, you confirm you are authorized to bind it to these Terms.

2. What the App is — and is not

The App is provided in a pre-release ("beta") state and may change, break, or be withdrawn at any time.

3. Your responsibilities

• Use the App safely. Set up phones, tripods, and running lanes so they do not create a hazard; supervise athletes; follow your organization's safety and medical rules.
• You are responsible for the athlete data you enter and for any consent required to record it (see Privacy Policy §6).
• Keep your own backups. Local storage can be cleared by the browser, the phone, or you. We cannot recover lost data.
• Do not attempt to interfere with other users' sessions, reverse-engineer the pairing protocol to disrupt it, or use the App in violation of any law.

4. Intellectual property

The App — including its name, logo, design, user interface, source code, detection method, calibration and threshold values, drill library, diagrams, instructions, and all other content — is owned by SFEC, Inc. and its licensors, and is protected by United States and international copyright, trademark, and trade-secret law. "Velocity Sprint" and the VS mark are marks of SFEC and may not be used without written permission. The App is not affiliated with any other timing-product vendor.

We grant you a personal, revocable, non-exclusive, non-transferable license to use the App for its intended purpose: timing athletes. Except as that license expressly allows, or as applicable law permits notwithstanding this restriction, you may not:

• copy, reproduce, download, scrape, or extract the App's code, content, drill library, or data, in whole or in part, other than the transient copies your browser makes to run it;
• reverse engineer, decompile, disassemble, or otherwise attempt to derive the App's source code, detection method, calibration values, or protocol;
• modify, translate, adapt, or create derivative works from the App or any part of it;
• use the App, or any knowledge of how it works, to build, train, or improve a competing product or service;
• remove, obscure, or alter any copyright, trademark, or proprietary notice;
• sell, rent, sublicense, or commercially exploit the App or access to it;
• use automated tools (bots, crawlers, scrapers) to access the App or its content.

Any use outside this license terminates it automatically. SFEC reserves all rights not expressly granted and may pursue any remedy available at law or in equity, including injunctive relief, for unauthorized use.

5. Pricing

Velocity Sprint is sold as a subscription with a 2-day free trial that requires a payment card. When the trial ends, the card on file is charged for the plan you chose, and the plan renews automatically at the same price until you cancel. We will tell you by email at least 30 days before any price change.

Cancelling: open the app, go to Settings, scroll to the bottom and tap Manage subscription, then Cancel. Cancellation is immediate to request and takes effect at the end of the period you have paid for; you keep access until then. Refunds for a period already charged are handled case by case through support.

One phone, no sharing: an account works on one phone at a time. Signing in on another phone moves the account and signs the first phone out; we email you each time. Accounts may not be shared. Within any 90 days: the third phone change triggers a warning, the sixth suspends the account for 15 days, and the ninth suspends it for 30 days. Suspension for sharing is not refunded.

6. Disclaimer of warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ACCURACY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that timing results are accurate, that the App will be uninterrupted or error-free, or that data will not be lost.

7. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, SFEC, INC. AND ITS OFFICERS, EMPLOYEES, AND CONTRACTORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, INJURY, OR LOSS ARISING FROM RELIANCE ON TIMING RESULTS, ARISING OUT OF OR RELATED TO THE APP. OUR TOTAL LIABILITY FOR ANY CLAIM SHALL NOT EXCEED THE AMOUNT YOU PAID US FOR THE APP IN THE TWELVE MONTHS BEFORE THE CLAIM, OR US $50 IF YOU PAID NOTHING. Some jurisdictions do not allow these limitations; in that case they apply to the maximum extent permitted.

8. Indemnity

You agree to indemnify and hold us harmless from claims arising from your use of the App, your athlete data, or your breach of these Terms.

9. Termination

You may stop using the App at any time; erase local data from Settings. We may suspend or discontinue the App, or restrict access for misuse, at any time. Suspension under the sharing rule in section 5 is not a termination; billing continues and access returns when the suspension ends.

10. Governing law

These Terms are governed by the laws of the State of Florida, USA, without regard to conflict-of-law rules. Any dispute shall be brought in the state or federal courts located in Miami-Dade County, Florida, and you consent to their jurisdiction. If any provision is found unenforceable, the rest remains in effect.
