Privacy Policy — Copper Keto Companion

Last updated: June 9, 2026
Effective date: June 9, 2026

Copper Keto Companion ("the App," "we," "us," "our") is an iOS application that provides educational tracking and behavioral coaching for the ketogenic diet through conversational logging, weight trends, and personalized feedback. The App is currently offered only in the United States via the U.S. App Store; see "Availability outside the United States" below. This Privacy Policy explains what data we collect, why we collect it, how we use it, how long we keep it, how we protect it, and your rights regarding your data. It applies to all data we collect from the effective date forward, and is specifically about the iOS App; for our website's privacy practices, see coppersuncompanion.com/privacy.

The App is operated by Copper Sun Content and Creative, LLC("the Company"), a single-member limited liability company based in the United States.

If you have questions about this policy, contact us at support [at] coppersuncreative [dot] com. You can also access this policy at any time from within the App and at coppersuncompanion.com/keto/privacy.


Privacy in 60 seconds


What we collect

We collect data in the categories below, all stored under your individual account.

1. Account information

When you sign in, we collect your email address through our authentication provider (Supabase). We use it to recognize you across sessions, sync your data across devices, and contact you about account or service issues. We do not use your email for marketing.

2. Information you give us about yourself

When you tell the App about yourself — your height, weight, age, daily macro targets, your stated goal, your food preferences, your meals, your weigh-ins, your ketone readings — we store that information so the App's coaching can reference it on later conversations. You decide what to share; nothing is required beyond an email and a sign-in.

Voice input.The App lets you log meals, weights, and observations by voice. Speech recognition runs on your device using Apple's on-device Speech framework — the raw audio of what you say does not leave your device. We receive only the transcribed text, which is then handled the same as anything you type. We do not create or store voiceprints or any other biometric identifier.

You can review what we've stored about you at any time by asking the App, and you can clear specific fields or your full account from within the App's Settings.

3. Data from Apple Health

If you grant permission, the App reads selected metrics from Apple Health (weight, body fat percentage, resting heart rate, sleep, water intake, and any food/nutrition data you've authorized). We store these metrics in our backend database (hosted by Supabase) so the App's coaching can recognize trends across weeks and months — for example, noticing that your weight stalls track with poor sleep, or that your protein intake has trended low. The first time you connect Apple Health, the App backfills a recent window of history per metric (typically 30 to 180 days, depending on the metric); after that, only new readings sync as they arrive.

The App may also write voice-logged weights and nutrition data back to Apple Health so your other health apps stay current. You control these permissions through iOS Settings → Privacy & Security → Health → Copper Keto, and may withdraw any or all permissions at any time.

Apple HealthKit data use.Consistent with Apple's App Store Review Guideline 5.1.3, we do not use Apple Health data for advertising or other use-based data mining purposes other than improving health, medical, and fitness management within the App. We do not share Apple Health data with any third party for advertising or use-based data mining purposes, and we do not sell Apple Health data.

4. Service operation data

We collect minimal technical data to keep the App running:

We do not attempt to re-identify users from anonymized telemetry, and we do not combine telemetry with marketing data sets.

5. Tracking technologies

The App does notuse cookies, web beacons, pixels, advertising SDKs, fingerprinting, or any similar tracking technologies. We do not use Apple's App Tracking Transparency framework because we have nothing to track. We do not embed third-party widgets or analytics scripts that might set their own identifiers.

6. Payment information

We do notcollect or store payment information. Subscription payments are processed entirely by Apple through the App Store, and subscription state (active, lapsed, refunded, in trial) is tracked by RevenueCat using only an opaque user identifier. We never see your card number, billing address, or any other payment-method detail. To request a refund, manage billing, or cancel, use iOS Settings → [your Apple ID] → Subscriptions, or Apple's Report a Problem page.

7. What we do NOT collect

We deliberately design the App to collect as little as possible. We do not collect or process:


How we use your data

We use your data only for these purposes:

  1. To provide the App's core functionality— answering your questions, tracking your goals, surfacing patterns in your data, and adapting coaching to what you've told us.
  2. To send your conversations to a third-party AI provider to generate responses. Your messages and relevant context are transmitted to the provider's commercial API for processing under a zero-data-retention configuration — the data is not retained, is not used to train AI models, and is processed on servers located in the United States.
  3. To diagnose and fix problems with the App.
  4. To respond to you if you contact support.

We do not sell your personal information, share it with advertisers, or use it for cross-app tracking. We also do not share personal information for cross-context behavioral advertising as those terms are defined under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA).

Aggregated and de-identified data

We may create aggregated or de-identified data sets from the data we hold — for example, "average response time for new users in their first week" — and use those to improve the App and our service. De-identified data is treated as such for as long as we hold it; we do not attempt to re-identify users from de-identified data, and we do not allow our service providers to do so on our behalf.

Profiling and automated processing

We build a profile of you within the App — your food preferences, goals, weigh-in history, behavioral patterns the AI has observed over time, and similar information. This profile exists only to personalize the App's coaching to you, and is used in no other way. We do not use profiling for advertising, marketing, demographic analysis, sale, or any commercial purpose outside the App's core function.

The App's coaching responses are generated by AI based on data you've shared. These are educational suggestions to help you follow a ketogenic protocol; they are not medical advice and do not produce legal or similarly significant effects on you within the meaning of GDPR Article 22. You always make the final decisions about your diet and health.


Who can access your data

We share your data only with the following service providers, all under contract to handle your data only as instructed and only to provide their service to us:

ProviderWhat they handlePurpose

Subprocessors

Our service providers may engage their own subprocessors consistent with their contracts with us — for example, cloud-infrastructure providers behind Supabase or our AI provider. We require all providers to implement appropriate technical and organizational safeguards for your data, including encryption in transit and access controls.

International data transfers

These providers process data in the United States and other jurisdictions. Where data flows from the European Union, United Kingdom, or Switzerland to the United States, we and our providers rely on the EU-US, UK-US, and Swiss-US Data Privacy Framework certifications and/or Standard Contractual Clauses approved by the European Commission. You may request more information about these safeguards by contacting us at the address above.


How we protect your data

We take reasonable technical and organizational measures designed to protect your data against unauthorized access, accidental loss, alteration, and disclosure:

No system is perfectly secure; we cannot guarantee absolute security. In the event of a data breach affecting your personal information, we will notify you and applicable regulators without undue delay, as required by law (including GDPR Article 33/34, the UK GDPR, CCPA, Washington's My Health My Data Act, and other state breach- notification statutes).


How long we keep your data

We retain your data for as long as your account is active. After you delete your account (Settings → Delete Account in the App), we erase your data from our production systems immediately. Backup copies held by our hosting providers for disaster recovery are retained for up to 30 days, after which they are also deleted.

Service operation data (Sentry errors, Axiom telemetry) is retained for up to 90 days for diagnostic purposes, then automatically purged. Aggregated or de-identified data may be retained in de-identified form for service-improvement purposes.


Your rights and choices

Availability outside the United States

The App is currently offered only in the United States via the U.S. App Store and is not made available for download in the European Union, United Kingdom, Switzerland, Canada, Brazil, or other non-U.S. App Store storefronts. We do not market the App to residents of those regions, and we do not process the personal data of non-U.S. residents in the ordinary course of operating the App.

Before we expand availability to any non-U.S. region, we will make the registrations and designations required by that region's privacy law — including, where applicable, an EU Article 27 representative, a UK GDPR representative, a Swiss FADP representative, a South Korean PIPA domestic representative, or a Brazilian LGPD operator — and we will update this Privacy Policy to describe the statutory rights available to residents of that region (under the GDPR, UK GDPR, Swiss FADP, PIPEDA, LGPD, PIPA, or other applicable law) before processing their data.

If you believe you are a resident of a non-U.S. region and have accessed the App, please contact us using the address above. The rights described in this policy — access, correction, deletion, portability — are available to you as a matter of our policy regardless of where the App is currently offered.

California (CCPA / CPRA)

For California residents, the rights above implement your statutory rights of access, deletion, correction, and portability under the CCPA/CPRA. The App processes Sensitive Personal Information (health and fitness data, account credentials) solely to provide the service you requested; we do not use Sensitive Personal Information for any purpose beyond providing that service. We do not sell personal information, and we do not share personal information for cross-context behavioral advertising.

Right to appeal.If we deny a privacy request you have submitted, you may appeal our decision by emailing the contact address above with the subject line "CCPA APPEAL" and a brief description of the request. We will respond to your appeal within sixty (60) days.

Consumer Health Data (Washington MHMDA and similar laws)

For users in Washington state, Nevada, Connecticut, and other jurisdictions with consumer-health-data laws, the metrics described above (weight, body fat percentage, resting heart rate, sleep, water intake, food and macro logs, ketone readings, exercise) constitute consumer health data. We collect and process this data solely to provide the App's core functionality and personalized coaching. We do not share consumer health data with any third party for purposes beyond the service providers listed above, and we do not use it for targeted advertising or sale. To request access, correction, deletion, or withdrawal of consent regarding your consumer health data, use the methods described above; we may verify your identity before fulfilling such requests.

Other U.S. states

Residents of Colorado, Connecticut, Virginia, Utah, Texas, and other U.S. states with comprehensive consumer privacy laws have the rights of access, correction, deletion, and opt-out of targeted advertising and sales, where applicable. We do not engage in targeted advertising or sale of personal information.

Children

We do not knowingly collect data from children under 13, the threshold under the U.S. Children's Online Privacy Protection Act (COPPA). The App is rated 4+ on the App Store because it contains no objectionable content, but it is designed for adults managing their own ketogenic diet. If you believe a child has provided us with personal information, please contact us and we will delete it.


Medical disclaimer

The App is for educational and behavioral coaching purposes only. It does not provide medical advice, diagnosis, or treatment, and is not a substitute for professional medical care. The Company is not a HIPAA-covered entity or healthcare provider, and the App is not a medical device. Always consult a qualified healthcare provider before starting or modifying a ketogenic diet, especially if you have diabetes, kidney disease, are pregnant or breastfeeding, are taking prescription medications (including insulin, sulfonylureas, or blood-pressure medications), or have other medical conditions. If you experience symptoms that concern you, contact a healthcare professional or emergency services. Do not rely on the App for medical decisions.


Changes to this policy

We will update this Privacy Policy when our data practices change. The "Last updated" date at the top reflects the most recent change. For material changes, we will notify you through the App or by email before they take effect. You can always access the current version of this policy from within the App or at coppersuncompanion.com/keto/privacy.
