Permission Breakdown for Zeit365 Registration

Zeit365 is a professional time tracking and project management application that integrates seamlessly with your Microsoft 365 environment to help you track work time, manage projects, and bill customers effectively. Here's why each permission is essential for the app to function properly:

Core Identity & Authentication

  • - openid - Allows you to securely sign in with your Microsoft 365 account
  • - profile - Displays your name and basic profile information in the app interface
  • - offline_access - Keeps you logged in so you don't have to re-authenticate every time you use the app

User Management & Collaboration

  • - User.Read - Reads your basic user profile to personalize your experience
  • - User.ReadBasic.All - Displays colleague names and basic info when you collaborate on projects or assign time entries to team members

Team & Project Organization

  • - Group.Read.All - Critical for Zeit365's core functionality: The app uses Microsoft 365 Groups to organize your customers and projects. When you create a customer in Zeit365, you link it to a Microsoft 365 Group, which:
  • - Determines access control - Only members of the linked group can view that customer's time entries and project data
  • - Provides customer branding - The group's profile picture becomes the customer's logo in Zeit365
  • - Enables seamless collaboration - Your existing team structure in Microsoft 365 automatically applies to Zeit365
  • - GroupMember.Read.All - Identifies who has access to which customer projects based on group membership, ensuring proper access control and privacy

Document & Workspace Integration

  • - Sites.Read.All - Provides direct links to related SharePoint sites, Teams channels, and Microsoft 365 services for each customer group, so you can quickly access:
  • - Customer documents and files
  • - Team conversations and planning tools (Planner, OneNote)
  • - Shared calendars and resources

Why This Builds Trust

Minimal Data Access: Zeit365 only reads the information it needs - it cannot modify your Microsoft 365 data, delete files, or send emails on your behalf
Leverages Existing Structure: Instead of creating a separate user management system, Zeit365 uses your existing Microsoft 365 groups and permissions, reducing security risks
Transparent Purpose: Every permission directly supports Zeit365's core features of time tracking, project management, and customer billing
Enterprise-Grade Security: Zeit365 uses Microsoft's enterprise authentication system, which means your login credentials never leave Microsoft's secure environment
Granular Access Control: Your Microsoft 365 group memberships automatically determine what customer data you can see in Zeit365, maintaining your organization's existing privacy boundaries

Once you confirm, you'll be asked to Login to your microsoft Account. If you do we will create your Zeit365 App Instance and you will be redirected to your Admin Center!

How Zeit365 Ensures Your Tenant’s Data Is Secure

Discover how Zeit365 protects your organization’s data through dedicated databases, encrypted replication, and security-by-design architecture.

# Developer's Journal

Security at the Foundation

For modern organizations, data is more than just information — it’s intellectual property, reputation, and the foundation of customer trust. At Zeit365, we believe that protecting that data isn’t merely a compliance checkbox — it’s the core of how we design, build, and deliver technology.

Whether you’re a compliance officer, a business leader, or exploring new tools for your company, Zeit365 provides the security, transparency, and scalability you need to operate with confidence in a digital world.

1. Dedicated Databases for Each Tenant: True Isolation, Complete Control

Unlike traditional shared environments, each Zeit365 tenant operates within its own dedicated database. Your data is never mixed with other organizations, and there’s zero risk of cross-access or accidental exposure.

This separation does more than just prevent security incidents — it simplifies compliance with data protection frameworks such as GDPR, HIPAA, or ISO 27001 by providing a clear, auditable boundary around your organization’s information.

For your business, this means:

  • Regulatory peace of mind – Easy mapping to compliance requirements for data segregation.
  • Streamlined audits – Clean, isolated environments simplify evidence gathering.
  • Flexible configuration – Customize settings and integrations without affecting other tenants.

Maximum data isolation and full control over access — your tenant’s data remains yours, always.

2. Encrypted Local Replicas: Secure Performance, Anytime, Anywhere

At Zeit365, performance and protection go hand in hand. To maintain high availability and responsiveness, every tenant’s database is replicated locally in encrypted form — ensuring that users experience seamless performance even during periods of heavy demand or network fluctuations.

Our encryption practices follow the latest industry standards, meaning that even if someone accessed the replicas, the data would remain unreadable and protected.

What this means for you:

  • Business continuity – Uninterrupted access, even during infrastructure updates or regional slowdowns.
  • Consistent user experience – Security never comes at the cost of speed.
  • Data integrity guaranteed – Replicas and backups are always encrypted, verified, and monitored.

Fast access, continuous protection — your workflows stay efficient and secure around the clock.

3. Security by Design: Compliance Meets Scalability

At Zeit365, we view security and compliance as innovation drivers, not restrictions. Our multi - layered “security by design” approach ensures your organization’s data stays safe, available, and compliant — no matter how you scale.

Our principles include:

  • Least-privilege access – Only authorized users can view or modify sensitive data.
  • Audit-ready logging – Every action is traceable and transparent, ensuring full governance oversight.
  • Proactive monitoring – Real-time alerts and automated defense layers enhance visibility and response times.

This means your compliance officers gain deeper data transparency, your leadership gains trust, and your teams gain secure flexibility to perform at their best.

Building Trust Through Transparency

Choosing a new tool for your organization requires confidence — not just in features, but in the integrity of the system behind them. With Zeit365, every design decision reinforces that trust.

Our dedicated databases, encrypted replication, and compliance-centric controls are more than technical measures — they’re the framework of a platform that aligns with your governance, risk, and compliance objectives from day one.
