Privacy Policy
Effective October 26, 2026
This policy explains what information CoreCnx collects, why, and what you can do about it. CoreCnx is run by DB Technology Solutions LLC ("we", "us"). We don't sell your information, and we don't show ads.
Teachers: what we collect
- Account details: your name, email address, password (stored scrambled, so we can't read it), and your two-factor authentication setup if you turn it on.
- Billing: Stripe handles your card. We keep the ID Stripe gives us for you and your plan's status and payment history, but never your full card number.
- Your library: the videos and thumbnails you upload, and the titles, classes, sections and settings you create, including your link password if you set one.
- Messages: anything you send us through the contact form or by email.
- Activity records: when you sign in, and a record of account and billing actions, which can include your IP address and browser type. We use these to keep accounts secure and to sort out billing questions.
Students: what we collect
Students don't create accounts, and we don't ask them for a name or email address. When someone opens a teacher's link, we use:
- a cookie that remembers they've entered the right link (and password), so they don't have to enter it on every page; and
- their IP address, briefly, to limit how many wrong passwords can be tried.
We don't build profiles of students or track what they do on other sites. CoreCnx isn't directed at children, and we don't knowingly collect personal information from children under 13. If you believe a child has given us personal information, contact us and we'll delete it.
How we use it
- to run CoreCnx: store and play your videos, and share them through your link;
- to charge for your plan and handle failed payments;
- to send emails you need, like password resets and important notices about your account or these policies;
- to keep the service secure, prevent abuse, and fix errors;
- to answer your messages; and
- when the law requires it.
Who we share it with
We use these companies to run CoreCnx. Each one gets only what it needs to do its job for us:
- Render: hosts the website and its database.
- Cloudflare (R2): stores your video files.
- Stripe: takes payments and manages subscriptions.
- Brevo: sends our emails.
- Sentry: reports errors in the site to us. We've set it not to send personal details like names or email addresses.
We may also share information if the law requires it, to protect people's safety or our rights, or as part of a sale or merger of the business (in which case this policy would still apply to your information).
Cookies
We use only the cookies the site needs to work: one that keeps you signed in (or remembers a student's access to a library), and one that protects forms from forgery. Your choice of light or dark screen is saved in your own browser. We don't use advertising or tracking cookies.
How long we keep it
- While your account is open, we keep your information so the service works.
- After your plan ends, we keep your videos for 90 days in case you come back, then we may delete them.
- If you close your account, we turn it off straight away: you can't sign in and your student link stops working. We keep your name, email address and billing history, because we need them for tax and accounting records and to answer billing questions. If you also want your name and email erased, email us and we'll do it, except where the law requires us to keep something.
- Stripe keeps its own payment records under its own policies.
Your choices and rights
- You can see and change your name, email and password on your account page.
- You can delete videos at any time from your library.
- You can ask us for a copy of the information we hold about you, or ask us to correct or delete it, by emailing support@corecnx.com. We'll reply within 30 days.
- Depending on where you live, you may have other rights under your local law. Contact us and we'll help.
Security
We use HTTPS on every page, offer two-factor sign-in for teachers, store passwords scrambled, and keep video files in private storage that only plays through CoreCnx. No system is perfectly secure, but if we learn of a breach that affects your information, we'll tell you as the law requires.
Where your information is kept
CoreCnx is run from the United States, and your information is stored there or by our providers listed above. By using CoreCnx from outside the United States, you understand it will be handled there.
Changes to this policy
If we change this policy in a significant way, we'll email teachers before the change takes effect. The date at the top shows when it last changed.
