Privacy Policy

Last updated: August 25, 2026

1. Overview

This Privacy Policy describes how Sentinel Core Vision, a sole proprietorship ("we", "us", "our") handles personal data in connection with the SentinelLabeler desktop application, its local dashboard, our licensing service, and our websites (together, the "Service"). It covers what we collect, why we collect it, who we share it with, how long we keep it, and the rights you have.

SentinelLabeler is a dataset-labeling desktop application for Windows, paired with a local dashboard you open in your browser. The labeling and AI-assist work happens on your own hardware. Because of that, the amount of personal data we collect is deliberately small. This Policy applies to that data; it does not describe the footage, datasets, or models you choose to process locally on your own machine, which we never receive.

2. Who we are & how to contact us

We are Sentinel Core Vision, a sole proprietorship, and we are responsible for the personal data described in this Policy. You can reach us at support@sentinelcorevision.com. Please use the email address associated with your license or account where possible, so we can locate your records.

3. Information we collect

We collect only what we need to operate the Service. In practice, that is:

• Account & sign-in data. When you create an account or sign in, we process your email address and authentication details. Accounts and authentication are handled through Supabase, our authentication and database provider.
• Purchase & billing data. When you buy a plan, our payment processor Stripe collects your payment details and shares limited transaction data with us — for example, your email address, the plan you bought, and whether payment succeeded. We never see or store your full card number. Card data is handled by Stripe.
• License & activation data. We issue you a license key (in the form SNL-XXXX-XXXX-XXXX-XXXX) and record activation information for the device you activate on, used to enforce the machine limits of your plan.
• Support messages. If you contact us by email, we process the messages you send and any information you include in them so we can help you.
• Basic technical & log data. When the app validates a license or when you use our websites, our systems process ordinary technical data such as an IP address, timestamps, and request logs. We use this for validation, security, fraud prevention, and keeping the Service running.

4. How we use your information

We use the information above to:

• provide and activate the Service — deliver your license key, activate it on your device, and let you sign in and manage your account;
• process payments — take payment, manage subscriptions and renewals, issue receipts, and handle refunds through our payment processor;
• provide support — answer your questions and resolve issues you report;
• keep the Service secure and prevent fraud — validate licenses, honor machine limits, detect and prevent abuse, and protect the Service and our users; and
• comply with the law — meet our legal, tax, accounting, and record-keeping obligations, and respond to lawful requests.

We do not use your personal data to build advertising profiles, and we do not sell it.

5. Local-first processing on your device

SentinelLabeler is a local application. The footage, frames, datasets, and models it works with are processed on your own computer, using your own hardware. That content does not leave your PC through the app. We do not receive it, store it, or transmit it, and it is not part of the data described elsewhere in this Policy. Your projects, labels, and other local settings are stored on your machine. The only routine network activity the app performs is a lightweight check to our licensing service to confirm your license is valid, and — on first launch — downloading the AI runtime it needs to run locally.

6. Sharing & service providers

We do not sell your personal data. We share it only with the service providers we use to run the Service, and only to the extent each of them needs it to do their job. Our main providers are:

• Stripe — payment processing, subscriptions, and billing.
• Supabase — accounts, authentication, and database.
• Cloudflare — website hosting, delivery, and security.

We may also disclose personal data to advisers, authorities, or other parties where we are legally required to, or where it is reasonably necessary to protect our rights, our users, or the Service. If our business is transferred, personal data may be transferred as part of that transaction, subject to this Policy.

7. Cookies & local storage

Our marketing website is static and does not use advertising or cross-site tracking cookies. Where our websites or the app use cookies or local storage, it is limited to what is needed to make them work — for example, keeping you signed in on your own device.

8. Data retention

We keep personal data only for as long as we need it for the purposes described in this Policy. In general, that means:

• account, license, and activation data for the life of your account and license, and for a reasonable period afterward to handle reactivations, disputes, and security;
• billing and transaction records for as long as required for tax, accounting, and legal reasons; and
• support messages and logs for a limited period appropriate to their purpose.

When we no longer need personal data, we delete it or anonymize it. Some providers, such as our payment processor, keep records under their own retention rules.

9. Your rights

You can ask us to access, correct, or delete the personal data we hold about you. To make a request, email support@sentinelcorevision.com from the address associated with your account, and we will respond within the time required by applicable law.

Depending on where you live, you may have additional rights. For example, under the EU/UK GDPR you may generally have rights to access, rectification, erasure, restriction, portability, and objection, and the right to complain to your local data-protection authority. Under the California CCPA/CPRA you may generally have rights to know, delete, and correct your personal information, and a right not to be discriminated against for exercising them. We do not sell personal information. Which rights apply to you depends on your location and the applicable law; we will honor the rights that apply to you.

10. Security

We use reasonable technical and organizational measures to protect personal data, including encryption in transit for data that travels over the network and restricted access to the systems that hold it. We also rely on established providers (such as Stripe, Supabase, and Cloudflare) that maintain their own security programs. No method of transmission or storage is completely secure, so while we work to protect your data, we cannot guarantee absolute security.

11. Children

The Service is not directed to children, and we do not knowingly collect personal data from children under 16 (or under 13 where a lower age applies under local law). If you believe a child has provided us personal data, please contact us and we will take reasonable steps to delete it.

12. International transfers

We and our providers may process personal data in countries other than the one you live in, including the United States. Where personal data is transferred internationally, we rely on the safeguards recognized under applicable law — for example, adequacy decisions or standard contractual clauses — and on providers that offer appropriate protections.

13. Changes to this Policy

We may update this Policy from time to time as the Service, our providers, or the law change. When we do, we will update the "Last updated" date above, and for material changes we will take reasonable steps to let you know. Your continued use of the Service after an update means you accept the updated Policy.

14. Contact

If you have questions about this Policy or your personal data, or want to make a privacy request, email support@sentinelcorevision.com.

This Policy is provided for transparency and is not a statement of legal sufficiency; it may be revised as our practices and applicable law evolve.
