SaunaMind is a wellness app that helps you track training, sauna, cold exposure, hydration, and recovery using available session and heart-rate data. The app is currently in pre-launch testing on Apple's TestFlight and is not yet on the App Store. This policy covers both the SaunaMind website (sauna-mind.com) and the iOS app once it's installed on your device.
We've written this in plain English because health data deserves a straight answer, not a wall of legalese.
Website. If you join the waitlist or use the contact form, we collect the email address and any message you submit. Netlify, which hosts the site, keeps basic request logs (IP address, user agent, timestamp) for security and abuse prevention.
iOS app (when installed). When you create a SaunaMind account and use the app, we collect and store:
A note on wellness estimates. SaunaMind outputs such as Sauna Load, heat zones, cold recovery, hydration prompts, and readiness are proprietary wellness estimates. They are not direct clinical measurements and should not be treated as medical readings.
We use the data we collect to:
SaunaMind processes wellness and health-related data: heart rate, HRV/RMSSD where available, hydration entries, and your session history. We treat this category of data with extra care.
We use a small number of third-party services to run the app. Each one sees a specific slice of data for a specific purpose:
If you're in the European Economic Area or the United Kingdom, the legal bases we rely on are: (a) performance of a contract — for running the app functionality you signed up for; (b) legitimate interest — for crash reporting, debugging, security, and fraud prevention; and (c) your consent — for optional marketing emails and for connecting optional wearable integrations. You can withdraw consent at any time without affecting the lawfulness of processing based on consent before its withdrawal.
Depending on where you live, you may have the right to:
To exercise any of these rights, email privacy@sauna-mind.com. We'll respond within a reasonable timeframe and may ask for information to verify your identity before we act on a request.
Account data is retained for the life of your account plus 30 days after you request deletion, to give us time to complete the removal and handle any reversal request. Session data, wellness estimates, hydration entries, cold exposure data, and AI Coach conversation history are deleted alongside your account. Crash reports and error diagnostics are retained for 90 days. Contact-form submissions are retained for 12 months.
Several of our sub-processors are based in the United States or the European Union, so your data may be transferred across borders. Where this happens, we rely on the sub-processors' own standard contractual clauses and equivalent transfer safeguards. By using SaunaMind you understand that your data may be processed outside your country of residence.
SaunaMind is not intended for users under 18. We do not knowingly collect personal data from minors. If you believe a child has created an account, please contact privacy@sauna-mind.com and we'll delete the account and associated data.
We use reasonable technical and organisational safeguards to protect your data. In practice that means: TLS encryption for all network traffic between the app, the website, and our backend; at-rest encryption on our Postgres database via Supabase; password hashing via Supabase Auth using modern industry-standard algorithms (bcrypt/scrypt family) so we never store plaintext passwords; operational discipline around logging — user credentials and secrets are never written to application logs; row-level access controls; and restricted administrative access.
Honest caveat: no system is perfectly secure, and no provider can promise otherwise. If a notifiable data breach affects your personal information, we will notify affected users and relevant supervisory authorities, including the OAIC in Australia or the relevant EEA/UK authority where applicable, within the timeframes required by law.
The sauna-mind.com website uses Netlify's functional cookies only — needed for the site to work and for form submissions. There are no third-party analytics cookies, advertising pixels, or cross-site trackers. You can clear cookies through your browser at any time.
We may update this Privacy Policy from time to time as the app evolves or the law changes. Updates will be posted on this page with a new Last Updated date. Material changes will be flagged clearly.
Australian users: SaunaMind is an Australian-registered company and handles personal information in accordance with the Australian Privacy Principles (APP) under the Privacy Act 1988 (Cth). Health data is treated as sensitive information under APP 3 and collected with your consent. To make a complaint, you may contact us at privacy@sauna-mind.com, or escalate to the Office of the Australian Information Commissioner (oaic.gov.au).
SAUNAMIND PTY LTD is based in Australia. During pre-launch, EEA and UK privacy requests should be sent to privacy@sauna-mind.com. If our processing requires appointment of an EU or UK representative as the service expands, we will list that representative here before actively offering the service in those markets.
California residents may have rights to know, access, correct, delete, and receive a portable copy of personal information, and to opt out of sale or sharing of personal information. SaunaMind does not sell personal information and does not share health data for cross-context behavioural advertising. To exercise California privacy rights, email privacy@sauna-mind.com.

SaunaMind is in TestFlight now. Join the waitlist to hear first when founding-member access opens.
Join the WaitlistSaunaMind is a general wellness and fitness application. It does not provide medical advice, diagnosis, treatment, prevention, or monitoring of any disease or medical condition.
Sauna Load, heat zones, recovery scores, hydration prompts, and related metrics are proprietary wellness estimates based on available sensor data. They are not clinical measurements and should not be used for medical decision-making.
Heat and cold exposure carry real risks. Always consult a qualified healthcare professional before beginning sauna, cold plunge, or contrast therapy — especially if you have cardiovascular conditions, are pregnant, are taking medication, or have any pre-existing medical condition.
