Privacy Policy for Ketorra
Last Updated: May 2026
Overview
Ketorra is a keto diet and fasting tracker developed by Mekatronyx. Your privacy is important to us. This policy explains what data the App accesses and how it is handled.
What stays on your device
Your health and nutrition data is stored locally on your device and is never sent to Mekatronyx or any third party.
The App does not require an account or login, does not collect your name, email, or contact information, does not track your location, contains no advertisements, and uses no analytics or third-party tracking services.
The following data is stored locally on your device using Apple's SwiftData framework and never leaves your device unless you explicitly export it:
- Fasting sessions (start time, end time, duration)
- Meal entries and macro tracking (calories, fat, protein, carbs)
- Weight logs and body composition data
- Ketone and glucose readings
- Beverage and supplement logs
- Exercise sessions
- Custom recipes and shopping lists
- Journal notes
- User preferences, settings, and achievement progress
This data:
- Is not transmitted over the internet (except via Apple Health if you enable that integration, or CSV export if you initiate it)
- Is not accessible to Mekatronyx
- Is protected by iOS file-level encryption (only readable while your device is unlocked)
- Can be deleted by uninstalling the App or using Reset All Data in Settings
Fasting Circles — the one exception
Ketorra includes an optional, opt-in feature called Fasting Circles. If you choose to create or join a Circle, a small set of fasting-status data is synced via your iCloud account to Apple's CloudKit service so other members of your invited group can see your current fasting status in near real time.
Only the following fasting data is shared with members of Circles you join:
- The display name and avatar you choose for the Circle (set by you when you join)
- Whether you are currently fasting
- Your current fast's start time, target hours, plan (e.g., 16:8), and metabolic phase
- Your current fasting streak count
Your meals, macros, weight, body composition, glucose readings, ketone readings, supplements, recipes, shopping lists, journal notes, and achievements are NEVER shared — with anyone, ever. The Fasting Circles feature has no access to any of that data.
Technical details:
- Data sync uses Apple's CloudKit (the iCloud public database). Data is stored under your Apple ID's iCloud account, not on Mekatronyx servers. Mekatronyx has no access to your CloudKit data.
- You can see your data only with a valid iCloud sign-in on a device running Ketorra.
- Circle members can only see your fasting status while they are members of a Circle you are also in. They cannot follow you outside a Circle and cannot see Circles you have not invited them to.
- Invite codes are short alphanumeric strings shared by you out of band (text, in person, etc.). Knowing the code does not grant access without an iCloud account.
- Leaving a Circle removes your status from that Circle. Deleting a Circle you own deletes the Circle and removes all members from it.
- Reset All Data (Settings > Reset All Data) wipes your local database AND issues a best-effort delete of your member record and any Circles you own from CloudKit.
You are not required to use Fasting Circles. The rest of Ketorra works entirely without iCloud or any network connection.
Apple Health (HealthKit) Integration
Ketorra offers optional integration with Apple Health. If you grant permission, the App may:
Read from Apple Health:
- Weight and body composition data
- Workout/exercise data
Write to Apple Health:
- Weight entries you log in Ketorra
- Nutrition data (calories, macros) from meal entries
This integration is:
- Entirely optional — Ketorra works fully without it
- Permission-based — you choose exactly what data to share
- Processed locally on your device — no Health data is transmitted externally
- Revocable at any time through iOS Settings > Health > Ketorra
Ketorra does not access any Apple Health data beyond what is listed above. We do not access heart rate, sleep, menstrual cycle, medications, or any other Health categories.
Data Export
Ketorra includes a CSV export feature that allows you to save your tracked data to a file. This export is initiated only by you, creates a local file on your device, and is not automatically shared with anyone.
Notifications
Ketorra may send local notifications (e.g., fasting timer alerts, supplement reminders) if you grant notification permission. These notifications are generated entirely on your device, do not use push notification servers, and can be disabled in iOS Settings.
Children's Privacy
Ketorra does not collect any personal information from anyone, including children under the age of 13. However, the App is designed for adults managing their diet and health. It is not intended for use by children.
Third-Party Services
Ketorra does not integrate with any analytics, advertising, or tracking SDKs. No ads, no tracking pixels.
Apple services we do integrate with (only when you choose to enable them):
- HealthKit — optional, permission-based, processed locally (see above).
- CloudKit — only when you opt into Fasting Circles, only for the fasting-status fields listed in that section.
- WeatherKit / etc. — not used.
Data Security
Your data is protected by iOS file-level encryption (the SwiftData store is marked complete protection, meaning it is only readable while your device is unlocked), iOS app sandboxing, and end-to-end transport encryption (HTTPS / TLS) for any CloudKit traffic when you use Fasting Circles.
Your rights and choices
- Access: All your data is on your device. You can view, edit, and export it directly in the app.
- Export: Use the CSV export in History or Settings to save your tracked data.
- Delete: Use Settings > Reset All Data to wipe local data and any CloudKit data you have created. Uninstalling the app also removes all local data.
- Revoke Apple Health access: iOS Settings > Health > Ketorra.
- Disable iCloud sync: Sign out of iCloud or disable Ketorra in iOS Settings > [Your Name] > iCloud > Apps Using iCloud.

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last Updated" date above.
