Privacy Policy

Effective: April 20, 2026

This Privacy Policy describes how OKKAI ("we", "us", "our") collects, uses, and shares your personal data when you use the OKKAI mobile application and related services (the "Service").

1. Who We Are

OKKAI is the data controller for the personal data processed through the Service. If you have any questions about this policy or want to exercise any of your rights, contact us at support@okkai.app.

2. Data We Collect

We only collect what we need to run the Service.

  • Account identifiers — email address, hashed password, optional username and avatar. If you sign in with Apple or Google, we store the identifier the provider returns and, if you share it, the email address they pass to us.
  • Profile and goals — age, sex, height, current weight, goal weight, activity level, diet preferences, and the targets and pace you set.
  • Food and weight history — meals and items you log (name, portion, time, optional photo), nutrition values computed from them, and your weight entries over time.
  • Health and fitness data — only if you connect Apple Health, we read and write categories you explicitly authorise (for example dietary energy, macronutrients, body mass, active energy).
  • Device and usage data — device type, operating system, language, IP-derived country, and in-app events we use for reliability, analytics, and fraud prevention.
  • Subscription data — when you subscribe via the App Store we receive the Apple original transaction identifier, the product you bought, its status (trial, active, expired, refunded), and renewal dates. We never see or store your payment card.
  • Support correspondence — the content of any messages you send us.

3. How We Use Your Data

  • To provide the core Service — maintain your account, sync your logs, compute calorie and macro targets, render charts and insights.
  • To analyse photos you submit — we send your meal photo and your prompt to a large-language-model provider to infer ingredients and nutrition. We do not send your name, email, or account identifiers with the image.
  • To manage billing — verify Apple transactions, grant and revoke premium access, and prevent reuse of a single paid subscription across multiple accounts.
  • To communicate — transactional emails (password resets, important service notices) and, if you opt in, push notifications.
  • To keep the Service safe — detect abuse, investigate bugs, and comply with law.

4. Legal Basis (EEA and UK users)

We rely on: performance of the contract with you (to deliver the Service), your consent (for processing of sensitive health data and for cross-border transfer), our legitimate interests (to keep the Service secure and to improve it), and legal obligations (to retain tax records for paid transactions).

5. Third Parties We Share Data With

  • Apple — authentication (Sign in with Apple), in-app purchases, and Apple Health on your device.
  • Google — authentication (Sign in with Google), if you choose it.
  • Cloud infrastructure providers — database hosting and object storage in the United States.
  • AI providers — large-language-model vendors that process your meal photos and descriptions to return nutrition estimates.
  • Email and push delivery providers — strictly to deliver messages you asked for or that the Service requires.

We do not sell your personal data and we do not use it for advertising.

6. International Transfers

Our servers are located in the United States. When you use OKKAI outside the United States your personal data is transferred to and stored in the United States, where data-protection laws may differ from those in your country. Where required, we rely on your explicit consent (given at onboarding) or on appropriate safeguards such as the European Commission's Standard Contractual Clauses.

7. How Long We Keep Your Data

We keep your data for as long as your account is active. When you delete your account we delete or anonymise your personal data within 30 days, except where law requires us to keep a record for longer — for example, invoices for paid transactions, which we retain for 7 years for tax purposes.

8. Your Rights

You can at any time:

  • Access, correct, or delete your data — from inside the app at Settings → Delete Account, or by emailing us.
  • Withdraw a consent you previously gave without affecting processing already carried out.
  • Export a copy of the data you provided.
  • Object to or restrict certain processing, where applicable law gives you that right.
  • Lodge a complaint with your local supervisory authority.

If you have an active Apple subscription, deleting your OKKAI account does not cancel it. You must cancel in Settings → Apple ID → Subscriptions on your device; otherwise Apple will continue to charge you.

9. Security

We protect your data with industry-standard measures: encryption in transit (TLS), hashed passwords, access controls on production systems, and continuous monitoring. No method of transmission or storage is perfectly secure, and we cannot guarantee absolute security, but we work hard to keep your data safe and to act quickly if something goes wrong.

10. Children

OKKAI is not directed to children under 13, and we do not knowingly collect personal data from them. If you believe a child has provided us data, contact us and we will delete it.

11. Changes to This Policy

When we make material changes we will notify you in the app before they take effect and update the effective date above. Continuing to use the Service after changes means you accept the updated policy.

12. Contact

Privacy questions and rights requests: support@okkai.app (use subject "Privacy"). We respond within 30 days.
