1. Introduction

This Privacy Policy explains how RC-Timing collects, uses, stores, and protects personal information when users interact with our application CloudSync.
This policy applies to all users of the App and to all data processed through Google APIs.

By using CloudSync, you agree to the practices described in this Privacy Policy.

2. Data We Access via Google APIs

CloudSync requests access only to the minimum data required to provide its calendar synchronization features.

Google Calendar Data

Depending on your selected Google OAuth scopes, CloudSync may access:

  • Google calendar list (read-only)

  • Calendar event metadata (title, description, location, start time, end time)

  • Calendar events (read and/or write, depending on the requested scopes)

Google User Information

If required by the chosen scope:

  • Basic Google profile information (email address, user ID)

CloudSync does not access:

  • Emails

  • Contacts

  • Google Drive files

  • Any other Google user data not required for app functionality

3. How CloudSync Uses Google User Data

CloudSync uses Google Calendar data strictly to enable reliable event synchronization.

Specifically, CloudSync may:

  • Retrieve the user’s Google calendars to display them in the App

  • Read existing Google Calendar events to compare them with local events

  • Create, modify, or update Google Calendar events when the user initiates a sync

  • Identify and authenticate the user via OAuth 2.0

CloudSync does not:

  • Use Google user data for advertising

  • Sell Google user data

  • Use Google user data for profiling

  • Use Google user data for AI or machine learning model training

All processing complies with the Google API Services User Data Policy.

4. Data Sharing

RC-Timing does not share Google user data with any third parties.

Data is only disclosed in the following rare cases:

  • If required by law (e.g., lawful governmental request)

  • If necessary to protect CloudSync from abuse, fraud, or security threats

Data is never sold, rented, or traded.

5. Data Storage & Protection

Local Storage

CloudSync may store the following securely on the user’s device or server:

  • OAuth access tokens needed to maintain authentication

  • Temporary cached calendar data for synchronization

No Google Calendar data is permanently stored unless explicitly required for sync functionality.

Security Measures

We use industry-standard security practices including:

  • Encrypted HTTPS connections

  • Secure OAuth 2.0 authentication

  • Secure storage of tokens

  • No logging of sensitive Google user data

We never store user passwords or raw credentials.

6. Data Retention & Deletion

Retention

We retain Google user data only as long as necessary to operate CloudSync.
Cached data is automatically deleted periodically or after synchronization.

User-Initiated Deletion

Users may request deletion of:

  • All local CloudSync data

  • All cached Google Calendar data

  • OAuth access/refresh tokens

Requests must be submitted to:
support@rc-timing.ch

We process deletion requests within 30 days.

Users may also revoke CloudSync’s Google account access at any time at:
https://myaccount.google.com/permissions

7. Children’s Privacy

CloudSync is not intended for children under 16 years of age and does not knowingly collect data from minors.

8. Changes to This Privacy Policy

We may update this Privacy Policy as needed. Changes will be posted on this page and indicated with a new “Last updated” date.
