Privacy Policy – Synqo

Last updated: October 2026

Synqo: AI Health Coach processes health data, so this page explains exactly what happens with it. In short: Synqo has no server of its own, no user accounts, no ads and no analytics. Your data stays on your iPhone and in your own iCloud. We, the developers, do not receive or see any of your data.

What data does the app process?

  • Apple Health (read): sleep, heart rate, resting heart rate, HRV, steps, energy burned, workouts with route and heart rate, breathing, blood oxygen, weight, body fat, blood pressure, VO₂ max, mindfulness and, if you turn it on, cycle data. You decide in the Health prompt which data the app may see.
  • Apple Health (write): only when you trigger it in the app or allow it in Settings: water, nutrition, body measurements (weight, BMI, body fat, lean mass), mindful minutes, mood and your cycle entries (period, symptoms, basal body temperature, ovulation test, sexual activity, contraception).
  • Your own entries: meals, water, caffeine, body measurements, cycle and mood entries, conversations with the coach, saved analyses, weekly goals, challenge progress and your settings (goals, sleep need, wake-up and bedtimes, language).
  • Well-being: meditation, the wind-down routine, stretching and the stress check are calculated on your device. The app stores their duration only as mindful minutes in Apple Health, if you allow it.

This data is used on your device for display, scores (recovery, strain, sleep, stress), analyses, reminders and widgets. It is not sold, not used for advertising and not sent to us. Apple Health data is not used for data mining or profiling.

Storage and iCloud

Data is stored locally on your device. Your own entries are backed up and synced between your devices through your private iCloud (Apple CloudKit). This storage belongs to your Apple account and we have no access to it. Access keys (see below) are kept in your device's Keychain.

AI features (optional)

Apple Intelligence: On suitable iPhones the coach (daily and weekly analysis, conversations, nutrition estimates, meal plan) can use Apple Intelligence. Processing runs entirely on your device. No data is sent to us or to other providers.

Your own API key: Alternatively you can enter your own API key from a provider in Settings: Anthropic (Claude), OpenAI (ChatGPT) or Google (Gemini). This is also needed for the more accurate photo analysis of meals and for reading body scale screenshots. When you then use an AI feature, your iPhone sends the data needed for it (for example daily values, your question, a photo or a screenshot) directly to the provider you chose. We do not see this data. The provider's privacy terms apply to its processing. This can involve a transfer to countries outside the EU, for example the USA. You pay the costs through your key with the provider. Without a key and without Apple Intelligence, no data is sent to AI providers.

Open Food Facts

When you search for a food or scan a barcode, the app sends the search term or barcode number to Open Food Facts (openfoodfacts.org) to find nutrition values. No health data is transmitted. For technical reasons the service receives your IP address.

intervals.icu (optional)

If you enter an API key from intervals.icu, the app fetches your workout and fitness data directly from there. The key is stored in the Keychain.

Garmin (optional)

Through Apple Health: If you turn on the connection to Apple Health in Garmin Connect, Synqo reads the Garmin values from Apple Health, like all other Health data. The permissions you grant in Apple Health apply.

Direct connection to Garmin Connect: If you connect your Garmin account to Synqo, the app retrieves your Garmin data with your explicit consent, for example activities, sleep, heart rate, resting heart rate, HRV, stress, Body Battery, steps and weight. If you turn it on in Settings, the app can also write entries such as weight back to Garmin Connect.

  • Purpose: The data is used solely to show you recovery, strain, sleep and analyses in Synqo.
  • Transfer and storage: The data goes directly between Garmin and your device. It does not pass through any servers of ours. Credentials and access keys are kept only in your device's Keychain. Garmin data is not synced to your iCloud.
  • No sharing: We do not share Garmin data with third parties, do not sell it, do not use it for advertising or profiling and do not train models with it. If you use the AI coach with your own API key, your device only sends the request you trigger to the provider you chose (see "AI features").
  • Deleting your Garmin data: You can delete your Garmin data at any time. In the app, sign out under Settings → Garmin Connect. This removes the credentials from the device and deletes the cached Garmin values. You can also clear the cache under Settings → Data. If you delete the app, all locally stored Garmin data is removed. On request, an email to synqo.ai@icloud.com is also enough. You delete Garmin data in your Garmin account in Garmin Connect, where you can also revoke Synqo's access. Entries that Synqo wrote to Garmin Connect are deleted in Garmin Connect.
  • Garmin as controller: Garmin's privacy terms apply to the processing of your data at Garmin. Garmin and Garmin Connect are trademarks of Garmin Ltd. or its subsidiaries. Synqo is not a Garmin product and is not endorsed by Garmin.

Camera and photos

The camera is used for meal photos and scanning barcodes, photos only when you choose them (for example a body scale screenshot). Images are processed on your device and only sent to an AI provider when you start the photo analysis with your own key.

Maps

The route of a workout is shown with Apple Maps. Apple's privacy terms apply to that.

Notifications, widgets and rating

Reminders (water, measuring, movement, bedtime) are local notifications of your device. Widgets read daily values from a shared storage on your device. No data leaves the device. The request for a rating is shown by Apple's system. Synqo receives no information from you in the process.

No sharing, no ads

Synqo contains no ads, no trackers and no analytics services. There is no registration.

Deleting and revoking

  • You delete entries in the app.
  • If you delete the app, local data is removed. Remove data in your iCloud under Settings → [your name] → iCloud → Manage Storage.
  • Values saved in Apple Health are deleted in the Health app. Change permissions under Health → Sharing → Apps → Synqo.
  • You can remove API keys in the app's Settings.

Your rights

Under the GDPR you have the right to access, rectification, erasure, restriction of processing and data portability, and the right to lodge a complaint with a data protection authority. Because we do not store any of your data, you exercise these rights directly through your device, your Apple account and the providers mentioned. If you have questions, write to us.

Children

Synqo is not aimed at children.

Changes

If this policy changes, the updated version will be published on this page.
