Privacy Policy

Primer (operated by PetRhino LLC) · Last updated: August 10, 2026

Summary: This policy explains what information Primer collects, how we use it, and your choices when you use the Primer mobile application, website, and related services (the "App").

Educational purposes, not clinical care. Primer is a daily course about how attention, feeling and reaction work. It is not therapy, diagnosis, or treatment, and it is not a substitute for care from a qualified professional. If you are in crisis, contact your local emergency services or a crisis line.

When using Primer, you may provide:

You can use Primer without an email address. An account is only needed to carry your progress to another device.

We do not collect precise location data.

2. How We Use Your Information

We do not sell your personal data.

3. AI Features and OpenAI

Primer's AI companion is powered by OpenAI (OpenAI, L.L.C., San Francisco, CA). To make these features work, the following is transmitted to OpenAI's API to generate your response:

OpenAI processes this data solely to generate the requested response. Under OpenAI's API terms, data submitted via the API is not used to train OpenAI's models. You can review OpenAI's privacy policy at https://openai.com/privacy.

AI responses are produced automatically and may be inaccurate or incomplete. They are intended for education and reflection, and are not clinical guidance.

Please avoid entering sensitive personal, legal, medical, or financial information into the App.

4. Rate Limiting

5. Subscriptions

Primer may offer a paid subscription that unlocks additional features or removes usage limits. Free users may have limited access to certain features.

Payments are processed by third-party providers (such as Apple or Google). We do not store your full payment details.

6. Data Sharing

We share limited data with service providers that help us operate the App:

Each provider is contractually obligated to protect your data and may only use it for the purposes for which it was shared. Only information necessary to operate the App is shared. We never sell your personal data.

7. Data Security

We take reasonable technical and organizational measures to protect your data. However, no system is 100% secure, and we cannot guarantee absolute security.

8. Data Retention

We retain your information only as long as necessary to provide the service, comply with legal obligations, resolve disputes, and improve the product.

You may request deletion of your account at any time from within the App or by contacting us. Deleting your account removes your progress and reflections.

9. Your Rights

Depending on your location, you may have the right to access, correct, delete, or request portability of your personal data, or withdraw consent where applicable.

Primer is intended for users aged 13 and older. We do not knowingly collect data from children under 13. If we learn we have collected data from a child under 13, we will delete it.
