The Postmaster is a correspondence-management application provided by Four Page Letter Co. and designed to help users organize, send, track, follow up on, and file professional correspondence. This Privacy Policy explains how The Postmaster handles information, including information used in connection with Google Workspace integrations.
Information You Enter Into The Postmaster
The Postmaster may store information that you choose to enter into the application, including:
- correspondence records
- sender and recipient information
- contact information
- matter or file names and numbers
- follow-up dates
- correspondence notes
- template content
- tracked-mail information
- user settings
- default signature information
Depending on the version of The Postmaster you use, this information may be stored locally in your browser or device. You are responsible for determining whether the information you enter into The Postmaster is appropriate for storage in the application and consistent with your organization’s confidentiality, privacy, security, and technology policies.
Google Workspace Integration
The Postmaster offers optional integration with Google Workspace. Google Workspace access is user-initiated and optional. The Postmaster does not require a Google account for its core correspondence-management functions.
Gmail
If you connect Gmail, The Postmaster may use authorized Google access to send email messages that you explicitly choose to send. The Postmaster does not:
- scan your Gmail inbox
- import your email history
- monitor incoming messages
- read unrelated Gmail messages
- automatically detect replies
- automatically create correspondence records from your Gmail inbox
The Postmaster only performs Gmail actions that you explicitly initiate through the application.
Google Calendar
If you connect Google Calendar, The Postmaster may create calendar events that you explicitly choose to add. These may include:
- correspondence follow-ups
- expected response dates
- records-request follow-ups
- scheduling reminders
- other correspondence-related events
The Postmaster does not silently create calendar events by default.
Google User Data
The Postmaster uses Google user data only to provide the Google-connected functionality requested by the user. Google user data is not sold. Google user data is not used for advertising. Google user data is not used to build advertising profiles. Google user data is not transferred to third parties except where necessary to provide functionality requested by the user, comply with applicable law, or protect the security and integrity of the service. The Postmaster’s use and transfer of information received from Google APIs will comply with the Google API Services User Data Policy, including applicable Limited Use requirements.
OAuth Authorization
The Postmaster uses Google’s OAuth authorization system to connect to supported Google Workspace services. The Postmaster does not request or store your Google password. Google controls the authorization screen and the permissions you approve. You may decline authorization and continue using The Postmaster without Google Workspace features.
Disconnecting Google Workspace
You may disconnect Google Workspace from within The Postmaster where that functionality is available. You may also manage or revoke application access through your Google Account security and permissions settings. Disconnecting Google Workspace does not automatically delete correspondence records that you previously created within The Postmaster.
Local Application Data
The Postmaster may use browser-based storage, including localStorage, to preserve application data and preferences. Browser-based storage may be affected if you:
- clear browser data
- use private or incognito browsing
- change browsers or devices
- reset the application
- remove application storage
Users are encouraged to use available backup/export tools regularly.
Backups and Exports
The Postmaster may allow users to export application information in formats such as JSON or CSV. Exported files may contain confidential or sensitive information. You are responsible for storing, transmitting, and protecting exported files appropriately.
Confidential and Legal Information
The Postmaster is designed for professional correspondence management and may be used in environments where correspondence contains confidential, privileged, personally identifiable, medical, legal, business, or other sensitive information. The Postmaster does not determine whether information is confidential or legally protected. Users are responsible for complying with:
- professional obligations
- confidentiality duties
- organizational policies
- privacy requirements
- security requirements
- applicable laws and regulations
Data Security
Reasonable measures are used to design The Postmaster in a privacy-conscious manner. However, no browser application, internet service, computer system, or method of electronic storage can be guaranteed to be completely secure. Users should use appropriate organizational and technical safeguards when handling sensitive correspondence.
Third-Party Services
The Postmaster may interact with third-party services selected by the user, including Google Workspace. Use of those third-party services is also governed by the terms and privacy policies of the applicable provider.
Children’s Privacy
The Postmaster is intended for professional and business use and is not directed to children.
Changes to This Privacy Policy
This Privacy Policy may be updated periodically to reflect product changes, legal requirements, or changes to supported integrations. The updated date shown at the top of this page will indicate when the policy was most recently revised.
