Last updated: June 26, 2026 · Aiclysm
1. Data Controller
The controller of your personal data is Václav Frček, a sole trader registered in the Czech Republic (IČO: 73408280), with registered place of business at Sokolovská 966/185, 190 00 Praha 9, Czech Republic, operating under the trade name "Aiclysm" (hereinafter "we", "us", "Aiclysm").
Contact for privacy inquiries: info@aiclysm.com
Supervisory authority: UOOU (Office for Personal Data Protection), Pplk. Sochora 27, 170 00 Prague 7, Czech Republic · uoou.gov.cz
2. What Data We Collect
2.1 Account Data
Email address, password (stored as a secure hash), language preference, and subscription status. Authentication is handled via password-based login. Email verification codes are used during registration and password recovery. We do not collect your name, phone number, or physical address unless you provide it voluntarily.
2.2 Health & Wearable Data
When you connect a wearable platform (Polar, Withings, Fitbit, Oura), we retrieve health-related data through their official APIs using OAuth 2.0, and we never access or store your login credentials. Garmin data is imported manually from the data export file you upload, as Garmin's official API is not yet available to us. Strava integration is temporarily paused.
| Category | Examples | Source |
|---|---|---|
| Heart Rate & HRV | Resting HR, HRV (RMSSD/SDNN), max HR | Garmin (manual import), Polar, Fitbit (HRV+RHR); Withings (RHR only); Oura (HRV+RHR) |
| Sleep | Sleep stages (deep, REM, light, awake), duration, sleep score | Garmin (manual import), Polar, Fitbit, Withings, Oura |
| Activity | Steps, active minutes, workouts, calories, distance | Garmin (manual import), Polar, Fitbit, Withings, Oura |
| Stress & Recovery | Stress score, body battery | Garmin (manual import) |
| Respiratory | Respiratory rate, SpO2 | Garmin (manual import), Fitbit, Withings (SpO2); Polar (breathing rate); Oura (SpO2, breathing rate) |
| Body Composition | Weight, body fat %, muscle mass, BMI | Withings, Fitbit, Garmin (manual import) |
| Blood Pressure | Systolic, diastolic, heart pulse | Withings |
| Body Temperature | Skin temperature, body temperature deviation | Withings, Fitbit, Oura |
2.3 Derived Health Indices
From the raw data above, our algorithms compute 12 proprietary health indices: Immunity, Recovery, Stress Load, Sleep Debt, Circadian Rhythm, ANS Balance, Illness Risk, Overtraining, Respiratory, Morning Energy, Sleep Quality, Cardiac Efficiency — plus Body Status, Biological Age across 8 domains, and Training Load analysis. These are algorithmic estimates, not clinical measurements.
2.4 Billing Data
MyBodyAI is free for all users. If you choose to support us with a voluntary subscription, payments are processed securely by Stripe (stripe.com). We store only your subscription status and Stripe customer ID. We never see or store your credit card number. For Stripe’s privacy practices, see stripe.com/privacy.
2.5 Technical Data
IP address, browser type, device information, and server access logs. These are used for security, debugging, and service improvement. We do not use advertising or tracking cookies. For anonymous usage statistics, we use Umami — a self-hosted, cookie-free analytics tool that collects no personal data (see Section 13).
3. Legal Basis for Processing
We process your personal data on the following legal bases under the GDPR:
- Contract performance (Art. 6(1)(b)) — to provide the MyBodyAI service, manage your account, and process your subscription.
- Explicit consent (Art. 9(2)(a)) — for processing health data (special category data). You grant this consent when connecting a wearable platform. You can withdraw consent at any time.
- Legitimate interest (Art. 6(1)(f)) — for security, fraud prevention, and service improvement.
- Legal obligation (Art. 6(1)(c)) — for tax records, accounting obligations, and compliance with Czech law.
4. How We Use Your Data
- To compute and display your health indices on the MyBodyAI dashboard
- To manage your account and subscription
- To send essential service notifications (e.g., subscription expiry, security alerts)
- To improve our algorithms using anonymized and aggregated data
- To comply with legal obligations
- To ensure security and prevent abuse of our services
5. Data Sharing & Third Parties
We share your data only with the following categories of recipients, all bound by data processing agreements (DPAs):
- Hosting provider — server infrastructure located in the EU
- Wearable platform APIs — data flows are user-initiated via OAuth; each platform's privacy policy governs their data handling
- Stripe — payment processing (if you choose to support us). Stripe processes payment data under their own privacy policy. We receive only subscription status.
- Open Wearables API — our own middleware service that securely connects to wearable platforms via OAuth 2.0. Hosted on the same EU server.
- Health Connect (Android) — our Android app with Google Health Connect integration is in development and not yet publicly available. Once released, health data may be read from Google Health Connect with your explicit permission and will stay on our servers — never shared.
- Sentry — error monitoring service (hosted in EU Frankfurt). Captures technical error reports (stack traces, browser type, URL) to help us fix bugs. No health data or personal identifiers are included in error reports. Sentry Privacy Policy.
We may disclose personal data to law enforcement or regulatory authorities only when required by law. We will notify you of such requests where legally permitted.
6. Provider-Specific Data Handling
Each wearable data provider has specific requirements for how we handle your data. We comply with all provider terms and policies:
| Provider | Data Caching | Deletion on Revocation | Attribution |
|---|---|---|---|
| Garmin (manual import) | Imported from your export | N/A | Data from your Garmin export |
| Polar | As needed for service | Tokens revoked, data deleted | Data sourced from Polar |
| Strava | Temporarily paused | Not currently syncing | — |
| Withings | As needed for service | Prompt deletion | — |
| Fitbit | As needed for service | Prompt deletion | — |
| Oura | As needed for service | Prompt deletion | — |
Strava data is shown only to the user who authorized the connection. We do not display one user's Strava activity data to other users. Strava data that becomes unavailable is immediately removed from our cache.
In addition to GDPR breach notification requirements (72 hours to supervisory authority), we will notify affected data providers within 24 hours of discovering a security breach, as required by their respective terms.
7. International Data Transfers
Your data is primarily stored on servers within the European Union. When data is transferred outside the EEA, we rely on EU Standard Contractual Clauses (SCCs) or adequacy decisions to ensure an adequate level of protection.
8. Data Retention
| Data Type | Retention Period |
|---|---|
| Account data | Until account deletion + 30 days |
| Health & wearable data | Until account deletion or integration disconnection |
| Computed health indices | Until account deletion |
| Billing records | 10 years (Czech tax law) |
| Server logs | 90 days |
After account deletion, all personal data is permanently erased within 30 days, including backups. Anonymized and aggregated data (which can no longer identify you) may be retained indefinitely for statistical purposes.
9. Data Security
We implement appropriate technical and organizational measures to protect your data:
- Encryption in transit (TLS 1.2+)
- Password-based authentication with secure hashing, and time-limited email verification codes for registration and password recovery
- Optional two-factor authentication (TOTP authenticator apps and WebAuthn passkeys) with one-time recovery codes
- OAuth 2.0 for wearable integrations — we never store your third-party credentials
- Regular security reviews and updates
- Breach notification to UOOU within 72 hours per GDPR Article 33, and to affected data providers within 24 hours
- OAuth tokens and API credentials encrypted at rest
10. Your Rights Under GDPR
You have the following rights regarding your personal data:
- Access (Art. 15) — obtain a copy of your personal data
- Rectification (Art. 16) — correct inaccurate data
- Erasure (Art. 17) — request deletion of your data ("right to be forgotten")
- Restriction (Art. 18) — restrict processing in certain circumstances
- Portability (Art. 20) — receive your data in a structured, machine-readable format
- Objection (Art. 21) — object to processing based on legitimate interest

To exercise any of these rights, contact us at info@aiclysm.com. We will respond within 30 days.
You can also exercise these rights directly in the app: go to your Dashboard and use Export My Data to download all your data in JSON format, or Delete Account to permanently erase your account and all associated data.
11. Automated Decision-Making & Profiling
MyBodyAI uses automated processing to compute health indices (such as Recovery, Stress Load, Illness Risk, Biological Age) from your wearable data. These scores are generated algorithmically based on published research and personalized to your historical data. No decisions with legal or similarly significant effects are made solely based on automated processing. All outputs are informational wellness insights, not medical diagnoses. You have the right to request human review of any automated assessment by contacting us.
12. Children's Data
MyBodyAI is not intended for users under 15 years of age (in accordance with Czech law). We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us and we will promptly delete it.
13. Cookies
We use only essential cookies necessary for the functioning of the service (session cookies, language preference). We do not use advertising or tracking cookies. No cookie consent banner is required for strictly necessary cookies under the ePrivacy Directive.
We use Umami, a privacy-focused, self-hosted web analytics tool, to understand website usage. Umami does not use cookies, does not collect personally identifiable information (PII), and does not track users across websites. All analytics data is stored on our own servers within the EU. No data is shared with third parties.
Affiliate Links
Some pages contain affiliate links to third-party retailers. When you click one, the affiliate network (such as Sovrn or CJ Affiliate) may set a cookie to attribute a possible purchase to us, and we may earn a commission at no extra cost to you. These networks process the click under their own privacy policies. We do not share your MyBodyAI account data with them. See our Affiliate Disclosure.
14. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be communicated via email or in-app notification at least 14 days before taking effect. The "Last updated" date at the top of this page will be revised accordingly.
