Physical and Administrative Safeguards: Mainstreet implements physical security at data centers and organizational safeguards such as staff training, written policies, and regular access reviews to ensure ongoing protection of all personal and sensitive business information.
Regular Audits and Monitoring: Systems are subject to active monitoring, regular security audits, and review of security controls to ensure that measures remain effective as threats evolve.

How Updates Are Managed:
Automatic Deployment: Mainstreet manages software updates server-side, so improvements and fixes are deployed without users needing to manually update anything on their own devices.
Continuous Improvement: Given industry standards and AI-driven features, updates may be rolled out in a rolling or agile release fashion—sometimes weekly or monthly—though large new features or integrations may be bundled and announced periodically.
User Notification: Any significant feature changes or scheduled maintenance periods are communicated in advance to users, usually via in-app notifications, emails, or status page announcements.
Mainstreet adopts a data policy that emphasizes user rights to access, deletion, and portability, in alignment with U.S. privacy frameworks such as the California Consumer Privacy Act (CCPA) and general industry standards:
User Rights: You retain significant rights over your personal and business data provided to Mainstreet. Mainstreet gives you the right to request access to, correct, or delete your personal information, subject to certain exceptions required by law. The company will not sell your personal data for monetary consideration and explicitly allows you to opt out of any activity that may be viewed as a sale under CCPA definitions (e.g., targeted advertising).
Non-Retaliation: Exercising your data ownership rights does not result in retaliation or discrimination by Mainstreet.
Right to Export: You may request a copy of your personal data collected by Mainstreet. This data will be provided in a structured, commonly used, and machine-readable format, making it feasible to transmit the data to another platform or provider.
Deletion and Correction: In addition to portability, you can request deletion of your data or correction of inaccuracies. Mainstreet will comply unless certain exceptions apply (e.g., legal compliance).
Terms and conditions for contract renewal and cancellation for Mainstreet (mainstreet.com), based on available data points from the company's public materials and industry practices:
Automatic Renewal: Mainstreet typically operates on a month-to-month or annual agreement that may auto-renew unless the user takes action to cancel. For most subscription-based services, the contract will continue to renew automatically until a formal cancellation is received and processed.
Notice Requirements: To avoid a renewal, users are generally required to provide written notice of cancellation, commonly at least 30 days in advance for monthly or annually renewing services. Notice is usually submitted by email or through the user’s account portal.
Changes to Terms and Pricing: Mainstreet reserves the right to update or change service prices and terms at any time. Users will be notified (typically by email or portal message) when updates to Terms of Service occur, and continued use constitutes acceptance of new terms.
Billing Practices: Recurring payments for services are processed automatically before the renewal date, often 30 days in advance. Services like Registered Agent or Privacy Address are billed annually as long as Mainstreet’s information is on file with the relevant state.
Voluntary Cancellation: Users can cancel at any time by providing written notice (e.g., email or through their portal). For services involving state records (e.g., Registered Agent), users must show proof that Mainstreet is no longer listed in public records to stop recurring charges.
Refund Policy: No refunds are issued for previous services, whether paid monthly or annually, and cancellation does not result in prorated reimbursement unless specifically requested and agreed upon within 30 days of purchase, and only if work has not yet been started. Full refunds are rare and only possible before work initiation.
Cancellation After Work Has Started: Once Mainstreet has initiated or completed work tied to annual renewals or compliance services, cancellations will take effect only at the end of the currently billed period, with no refunds for that cycle.
Outstanding Charges: If Mainstreet remains listed in state records after a service due date, users are responsible for all continued recurring charges and any administrative or state fees incurred for removal.
Mainstreet aligns its software and business processes with several widely recognized data privacy and compliance standards appropriate for SaaS financial and tax technology platforms serving U.S. businesses:
Data Privacy Regulations Compliance: Mainstreet's policies and platform are designed to comply with leading U.S. privacy frameworks, notably the California Consumer Privacy Act (CCPA). The company gives users the right to access, export, and delete their personal information, does not sell personal data for monetary consideration, and allows customers to opt out of activities considered a “sale” under CCPA definitions. These rights are verified with identity/authentication controls and are outlined clearly in Mainstreet’s public-facing privacy materials.
Data Portability and User Rights: Users can request a copy of all personal data collected by Mainstreet in a structured, commonly used, machine-readable format, supporting both data portability and deletion rights. Mainstreet commits to fulfilling such requests in line with applicable state and federal laws.
Data Security Best Practices: Although Mainstreet does not explicitly list certifications like SOC 2 or ISO 27001 on its site, their published security measures include encryption of data in transit and at rest, strong access controls, regular monitoring and audits, secure data destruction, and prompt breach notification procedures, all of which reflect compliance with industry-standard security frameworks for fintech SaaS applications.
No Data Selling or Unauthorized Sharing: Mainstreet is transparent in its privacy policy that it does not sell or share personal data for advertising or profiling purposes, a requirement under CCPA and a standard feature of modern privacy-focused SaaS solutions.
