Privacy policy

Last updated: June 10, 2026

Kaizmax (“the app”) helps its users follow a personalized diet and training program. This policy describes what data we collect, why, how it is protected, and what your rights are.

1. Data we collect

• Account: email address and password (hashed, never readable by us).
• Questionnaire profile: sex, year of birth, height, weight, goal, activity level, training experience, training location and gear, sport practiced, diet, exclusions (allergies) and food preferences.
• Tracking data: meals and workouts checked off, weigh-ins, loads lifted in sessions, declared slip-ups.
• Personal recipes (optional): the recipes you create (name, ingredients, macros, steps), visible only to you.
• Progress photos (optional): if you add any, they are stored in a private space strictly reserved for your account. You can delete them permanently at any time.
• Goal-advice photo (optional): this photo is sent for analysis then immediately deleted. It is never saved, neither by us nor in any technical logs.
• Website waitlist (optional): if you leave your email on the website before launch, it is used only to send you the app's launch announcement, then removed from the list. You can request its removal at any time via the contact below.

2. Purposes

• Generate and adjust your personalized diet and training program.
• Calculate your calorie needs and track your progress.
• Send you local reminders (meals, workouts, weigh-in) if you enable them — these reminders are handled on your device.
• Manage your Premium subscription where applicable.
• Notify you of the app's launch if you joined the website waitlist.

We do not use your data for advertising purposes and we do not sell it to anyone.

3. Hosting and sub-processors

• Supabase (database, authentication, storage) — data hosted in the European Union (Ireland region).
• Google Gemini — used occasionally for AI personalization of programs and analysis of the goal-advice photo. The data sent is limited to what is strictly necessary (questionnaire profile, nutritional targets, photo where applicable — not retained).
• RevenueCat — Premium subscription management (purchase identifier; never your health data).

4. Retention

Your data is kept as long as your account is active. Deleting your account deletes all of your data (profile, programs, tracking, photos) from our systems.

5. Your rights (GDPR)

Under the General Data Protection Regulation, you have rights of access, rectification, portability, erasure and objection. Most of these actions are possible directly in the app (edit the questionnaire, delete a photo). You can permanently delete your account and all your data at any time in the app: Settings → "Delete my account". For any other request:

Contact: [email protected]

You may also lodge a complaint with your local data protection authority.

6. Security

Exchanges between the app and our servers are encrypted (TLS). Data access is partitioned per user at the database level itself (row-level security): an account can technically only read its own data. Progress photos are only accessible via time-limited signed links generated for your session.

7. Minors

The app is not intended for people under 15 years of age.

8. Health disclaimer

The generated programs are indicative estimates based on recognized formulas. They do not constitute medical advice and replace neither a doctor, nor a dietitian, nor a certified coach.

9. Changes

This policy may change. The update date appears at the top of the page; significant changes will be flagged in the app.
