Privacy Policy

Marco55 provides training analytics and personalized workout planning. This policy explains how Marco55 uses account information and data received from connected services.

Account information

Marco55 processes the details you enter when registering and completing your profile, including your name, email, country, age, training preferences and physical profile. Your password is stored as a password hash. Account verification and password recovery use email messages.

Activity and wellness data

Your devices and connected services record your activities and wellness measurements. Marco55 does not record those measurements directly. With your authorization, Marco55 receives available data through Intervals.icu, including activities originating from Zwift or Garmin. Marco55 currently has no direct connection to Zwift or Garmin.

Available information may include activity dates, duration, sport, power, heart rate, training load and wellness metrics. Availability depends on your connected services, permissions and their sharing policies.

How the information is used

Marco55 processes and stores received data, your profile, calculated analytics and training plans to provide your account's services. Planned workouts are sent to your authorized Intervals.icu account for delivery through its connected services. Each athlete's information and plans belong to their own account.

Service providers

Marco55 uses Vercel for hosting and Upstash Redis for application storage. Intervals.icu supplies authorized activity and wellness data and receives planned workouts. Namecheap Private Email is used to send account verification and recovery emails from Marco55's configured sender account. Marco55 does not require access to an athlete's personal email inbox.

Authentication and technical information

Marco55 uses authentication cookies, device authorization and connection credentials to maintain access and authorized integrations. Technical request and error records support operation and diagnosis. Do not send passwords or connection tokens by email.

Disconnecting and stored information

You can revoke connected-service authorization through the relevant provider. Revocation prevents use of that authorization; it does not automatically erase information previously stored by Marco55. Ending the pilot leaves existing information visible in read-only mode and stops new data pulls, analytics calculations and workout generation under the service rules.

Questions and data requests

Contact info@marco55.com to ask about your information or request access, correction or deletion. Such requests require verification of account ownership. Provider-held information remains subject to that provider's own privacy policy.
