Your Privacy, Our Priority

At seazn, we take data privacy seriously — because your trust is everything. We know how personal hormonal health can be, and we’re committed to protecting your information with the highest standards of transparency, security, and control. Below, you’ll find our full Privacy Policy, which outlines exactly how we collect, use, and safeguard your data. No fine print, no surprises — just clarity and care.

Our Privacy Policy

Last updated: August 25, 2025

Important Disclaimer: Not Medical Advice

The information provided by the seazn app, including but not limited to, analytics, nutritional, exercise, and mindfulness tips, is for informational and educational purposes only. It is not intended as, and shall not be understood or construed as, medical or professional health advice. The Service is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Never disregard professional medical advice or delay in seeking it because of something you have read on this Service.

This Privacy Policy describes our policies and procedures on the collection, use and disclosure of your information when you use the Service and tells You about Your privacy rights and how the law protects You. We use Your Personal data to provide and improve the Service. By using the Service, You agree to the collection and use of information in accordance with this Privacy Policy. You can withdraw consent, turn automated predictions on/off, and delete your account.

This Policy applies to seazn’s websites, mobile/desktop apps, chatbots, and related services (the “Services”). It explains what personal information we collect, how we use it, how we share it, and your rights.

We keep this tight and transparent. Below we list the types of data, examples, why we collect them, and your controls.

Account & Contact Information

Examples: Email, hashed password, display name, preferred language, 18+ attestation. We do not require your street address.
Why we collect this: Create and secure your account; authenticate you; send service communications (e.g., receipts, critical notices); show the right language.
Your controls: You may update email/language in settings; you can delete your account at any time.

Self‑Reported Wellness & Lifestyle Data

Examples: Symptom logs, cycle information, mood/sleep/energy, lifestyle inputs, goals, check‑ins, feedback. You choose what to submit.
Why we collect this: To deliver the core experience—personalized tips, trends, progress views, and (if enabled) automated predictions of hot‑flash risk. We also use de‑identified/anonymized aggregates to understand usage and improve features.
Your controls: You decide what to log; you can edit/delete entries; you can turn predictions on/off; research participation is opt‑in and withdrawable.

App Activity & Device Data (Non‑marketing)

Examples: Device model/OS, app version, performance events, crash logs, basic diagnostics. No advertising identifiers.
Why we collect this: Keep the app reliable and secure, fix bugs, prevent fraud/abuse, and measure feature performance.
Your controls: Not used for ads. You can request restriction/objection where applicable; we minimize what we collect.

Subscription & Payments

Examples: Plan, renewal status, transaction metadata from Stripe (e.g., token, last4, card brand). We do not store full card numbers.
Why we collect this: Process payments, issue receipts, manage renewals, detect fraud, and comply with tax/accounting rules.
Your controls: You can cancel anytime in settings; use alternative payment methods Stripe supports.

Support & Communications

Examples: Emails/messages you send us, support tickets, in‑app feedback.
Why we collect this: Respond to you, resolve issues, improve service quality, and meet compliance obligations.
Your controls: Choose your contact channel; manage non‑essential email preferences.

Research Opt‑In (Optional)

Examples: If you opt in, we may use de‑identified/anonymized datasets or pseudonymized study IDs derived from your logs for research or product improvement.
Why we collect this: Advance women’s health insights and validate features while protecting your identity; publish only aggregated/anonymized outputs.
Your controls: Participation is voluntary and based on separate explicit consent that you can withdraw at any time in‑app without affecting your core service.

Derived Insights & Predictions

Examples: Hot‑flash risk predictions, timing windows, adherence trends.
Why we collect this: To personalize guidance and help you plan your day. Predictions are informational only; they are not medical advice.
Your controls: Predictions toggle in Settings → Privacy; request an explanation of the main factors and ask for human review.

Security & Audit Logs

Examples: Authentication events, IP address at login, timestamps, risk signals.
Why we collect this: Protect your account, detect suspicious activity, and meet legal/security obligations.
Your controls: Security logs are retained for limited periods and are not used for marketing.

Encryption & Anonymization. Personal data is encrypted in transit (TLS) and at rest. We anonymize or aggregate data for analytics/research where possible; anonymized data is no longer considered personal information.

How We Use Data

We use your data to: - Provide the Services (create and manage your account, store your logs, billing and receipts) — contract. - Generate predictions and tips (automated processing of self‑reported data to personalize your experience) — explicit consent for sensitive data. Toggle available to turn predictions on/off. - Customer support & communications — contract and legitimate interests. - Security, fraud prevention, and service integrity — legitimate interests. - Research/product improvement (optional) — explicit consent (separate opt‑in).

We do not sell your personal information.

Privacy by Default

  • Highest confidentiality by default for optional features (e.g., analytics/marketing).

  • Privacy officer identified below; their title and contact are published.

  • PIA (privacy impact assessment) before transfers of personal information outside Québec and for new systems involving personal data.

  • Breach management: incident register; notify the CAI and affected individuals where there is a risk of serious injury.

Automated Processing, Explanations & Human Review

seazn uses automated processing to generate risk predictions and recommendations. You can: - Turn predictions on/off at any time in Settings → Privacy; when off, we do not run the prediction engine for your account. - Request an explanation of the main factors that led to a prediction.
- Request human review of decisions that affect you.

Contact privacy@seaznhealth.com to exercise these rights.

Data Minimization, Encryption & Anonymization

  • Minimize: We collect only what’s needed to operate and improve the Services.

  • Encrypt: Personal data is encrypted in transit (TLS) and at rest (e.g., database/storage‑level encryption).

  • Anonymize & aggregate: We may anonymize or aggregate data for analytics and research. Anonymized data cannot reasonably identify you and is no longer personal information. Where data is de‑identified/pseudonymized but still linkable, we treat it as personal information and protect it accordingly.

Data Sharing

We share data with: - Service providers (processors) under contract, only as needed to provide the Services:
- Supabase (hosting/database; primary storage in Canada).
- Stripe (payments).
- Authorities where required by law or to protect rights, safety, and security.
We do not allow providers to use personal data for their own marketing.

Your Rights & Choices

Depending on your location, you may have rights to access, rectify, delete, restrict or object to processing, data portability, and to withdraw consent without affecting prior processing. You also have the right to:
- Deactivate predictions and withdraw research consent in‑app.
- Delete your account in‑app or by contacting us; we will delete personal data unless we must keep some for legal/accounting reasons.

To exercise rights, contact privacy@seaznhealth.com. If unresolved, you may contact your local authority (e.g., CAI in Québec; an EU data protection authority for EU residents).

Data Retention

We keep personal data only as long as necessary for the purposes described or as required by law. When no longer needed, we delete. Backups may persist for a limited period. We may retain aggregated/anonymized information.

Children

The Services are intended for individuals 18+. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact privacy@seaznhealth.com to request deletion.

Security

We implement technical and organizational measures appropriate to the sensitivity of the data, including encryption, access controls, least‑privilege, audit logging, and vendor due diligence. No system is perfectly secure; report concerns to privacy@seaznhealth.com.

Subprocessors

We maintain a list of subprocessors (e.g., Supabase, Stripe). We will update this list upon material changes and provide notice where required.

Changes to this Privacy Policy

We may update this Policy from time to time. If we make material changes, we will provide reasonable advance notice (e.g., in‑app notice or email). Continued use after the effective date constitutes acceptance.
