Privacy Policy

This Privacy Policy describes how Vyve Care ("Vyve", "we", "us", or "our") collects, uses, and protects information when you use our website (vyvecare.com), our mobile and web applications, and related services (together, the "Services"). By using the Services, you agree to the practices described here.

Our privacy principles

Vyve was built around a simple idea: your most personal data should belong to you. Three principles guide everything we do:

• On-device by default. Your cycle and health data is designed to live encrypted on your device, not in a central cloud profile of your body.
• We don't sell your data. We do not sell, rent, or trade your personal information, and we do not share your health data with advertisers or data brokers.
• Data minimization. We collect as little as possible to provide and improve the Services, and we let you delete your data at any time.

Information we collect

We aim to collect the minimum necessary. Depending on how you use the Services, this may include:

• Information you provide. If you choose to create an account, join a waitlist, or contact us, you may give us your email address or other details you submit. You can use core tracking features without an account.
• Health and cycle data you log. Data you enter in the app — such as period dates, symptoms, mood, flow, and related information. As described below, this is designed to remain on your device.
• Device and usage information. Limited technical information such as device type, operating system, app version, and crash diagnostics, used to keep the Services working and secure.
• Website information. When you visit our website, standard server logs and limited, privacy-respecting analytics may record information such as pages visited and general region, as described under "Cookies & analytics".

Your health and cycle data

The health information you log — your cycle, symptoms, and related entries — is the most sensitive data you can record about yourself, and we treat it that way. Vyve is designed so that this data is encrypted and stored on your device. Our predictive features are designed to run on your device wherever possible, so that being helpful never requires us to hold a copy of your body's data.

If we ever offer optional features such as encrypted backup or syncing across devices, those features are designed to be opt-in and end-to-end encrypted, meaning we are not able to read the contents. We will always describe such features clearly before you choose to use them. We do not use your health data for advertising, and we do not sell or share it with third parties for their own purposes.

How we use information

We use the limited information we collect to:

• Provide, maintain, and improve the Services and their features;
• Personalize predictions and insights (performed on your device wherever possible);
• Respond to your requests and provide customer support;
• Send you service-related communications, and — only if you opt in — product updates;
• Keep the Services secure, detect and prevent fraud or abuse, and fix bugs;
• Comply with legal obligations.

Sharing and disclosure

We do not sell your personal data. We only share information in limited circumstances:

• Service providers. Vetted vendors who help us operate the Services (for example, hosting or analytics), under contracts that require them to protect your data and use it only for the services they provide to us.
• With your direction. If you choose to export or share a report (for example, a PDF for your doctor), you control that sharing.
• Legal and safety. Where required by law, or to protect the rights, safety, and security of users and the public. Because health data is designed to stay on your device, there is generally no central store of it for us to disclose.
• Business transfers. If Vyve is involved in a merger, acquisition, or sale of assets, we will require any successor to honor the commitments in this policy and will notify you of material changes.

Cookies and analytics

Our website may use a limited number of cookies and privacy-respecting analytics to understand how the site is used and to improve it. We aim to avoid third-party advertising trackers. You can control cookies through your browser settings, and where required we will ask for your consent. See our Cookie Policy for more detail.

Your rights and choices

Depending on where you live, you may have rights over your personal information, including the right to access, correct, delete, or port your data, and to object to or restrict certain processing. Because your health data is designed to live on your device, you can typically view and delete it directly in the app at any time — including erasing everything in one step.

If you have an account or have given us your email, you can contact us to exercise your rights. Users in the European Economic Area, the United Kingdom, and similar jurisdictions have rights under the GDPR; users in California have rights under the CCPA/CPRA, including the right not to be discriminated against for exercising those rights. We do not "sell" or "share" personal information as those terms are defined under California law.

Data retention

Health data you log is retained on your device until you delete it. For limited information we hold (such as an email address you provided), we keep it only as long as needed for the purposes described here or as required by law, and then delete or anonymize it.

Data security

We use technical and organizational measures — including encryption — designed to protect your information. No method of storage or transmission is completely secure, but keeping sensitive data on your device by design significantly reduces the risk of a large-scale breach affecting your health information.

Children's privacy

The Services are not directed to children under the age of 13 (or the minimum age required in your country), and we do not knowingly collect personal information from them. Some of our content is written to be appropriate and helpful for teenagers learning about their cycle, but account features and data collection are intended for users who meet the minimum age. If you believe a child has provided us with personal information, please contact us and we will take appropriate steps.

International users

Vyve may be used around the world. Where we process limited information on our servers, it may be processed in countries other than your own. Where required, we use appropriate safeguards for such transfers. Your on-device data remains on your device regardless of location.

Changes to this policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date above and, where appropriate, provide additional notice. Your continued use of the Services after changes take effect means you accept the updated policy.

VyveSleep — App-Specific Disclosure

VyveSleep is a dream-journaling app. The following describes what data VyveSleep specifically collects, transmits, and processes — in addition to anything covered in the general policy above.

What VyveSleep collects on your device

• Dream text you journal (title + body)
• Symbols, archetype, and emotional tone extracted from your dream text (computed locally, never sent)
• Sleep score, habits, alarms, and journaling history
• Your chosen bedtime, wake target, and chronotype

All of this stays on your device, protected by iOS / Android operating-system encryption.

What VyveSleep transmits, and when

When — and only when — you tap "Decode this dream" or "Generate dream image" on a dream, that dream's text is sent to our backend server (vyve-sleep-api.vyveperiodtracker.workers.dev), which forwards it to:

• Anthropic (Claude) — to generate the AI dream interpretation. https://www.anthropic.com/privacy
• Together AI (Flux Schnell) — to generate the dream image. https://www.together.ai/privacy

Both providers are bound by their own privacy policies. Anthropic and Together do not retain customer API content for model training as of their current policies.

What VyveSleep does NOT do

• Does not sell your dream data or any user data
• Does not share your data with advertisers or analytics providers
• Does not use your dreams to train AI models
• Does not collect your name, email, contacts, location, or health data
• Does not require an account (anonymous-only at launch)

Your rights in VyveSleep

• Delete all your data inside the app: Open the You tab → Privacy section → tap "Delete all VyveSleep data". This wipes every dream, habit, alarm, sleep log, and setting on your device — instantly, no review or wait period.
• Delete any individual dream by long-pressing it in the Dreams tab.
• Uninstall the app to erase all local data.
• For any other request, including data deletion verification: privacy@vyvecare.com

Children

VyveSleep is not intended for users under 13. We do not knowingly collect data from minors.
