Privacy Policy

1. Who is responsible

OSTERA LLC is responsible for personal information about visitors to ostera.app, people who contact us, and the account holders and users of our customers. Contact: OSTERA LLC, 10850 N Dover St, Westminster, CO 80021, USA. Email: contact@ostera.app. Phone: +1 (970) 238-3416.

For the data your business enters about its own clients (names, contact details, appointments, notes), your business decides what is collected and why. We process that data on your behalf, under our Data Processing Addendum.

2. What we collect

• Contact details you send us: name, business name, email, phone and the content of your message.
• Account information: the names, email addresses and roles of the users of a customer account, and sign-in records.
• Subscription records: plan, subscription period and billing contact.
• Technical information: IP address, browser type and pages requested, kept in server logs for security and troubleshooting.

3. Why we use it

• To answer your questions and prepare a plan when you ask for one.
• To provide, secure and support the Service under our contract with your business.
• To manage subscriptions and keep the records the law requires.
• To send service notices, such as changes to the Service or these policies.

We do not sell personal information, and we do not use it for third-party advertising.

4. Who receives it

We share personal information only with service providers that help us run the Service, under contracts that limit their use of it: our hosting provider, our email delivery provider, and the provider that handles subscription billing. We may also disclose information when the law requires it or to protect our rights and users.

5. How long we keep it

Messages and contact requests: up to 24 months after our last exchange. Account and subscription records: for the duration of the subscription and then as long as needed for legal, tax and accounting purposes. Server logs: up to 90 days, unless needed to investigate a security incident.

6. Security

Connections to the website and the Service are encrypted (HTTPS). Access to customer data is limited by role and by sign-in. No system is perfectly secure; we will notify affected customers of a security incident as required by law.

7. Your choices and rights

You may ask us for access to, correction of, or deletion of personal information we hold about you, and object to certain uses. Depending on where you live, including under the Colorado Privacy Act where it applies, you may have additional rights. Write to contact@ostera.app; we will respond within the time the law requires and may need to verify your identity.

If you are a client of a business that uses Ostera, please contact that business first: it controls your appointment data. We will help it respond.

8. Cookies

This website uses only the cookies and similar storage it needs to work. See our Cookie Policy.

9. Children

The website and the Service are not directed to children under 13, and we do not knowingly collect their information.

10. International transfers

We are based in the United States. If you contact us from elsewhere, your information is processed in the United States.

11. Changes

We may update this policy and will show the new date at the top of this page. Last updated November 10, 2026.
