End User License Agreement

DealDoctor PLLC · Effective August 12, 2026

Important calendar-action notice. CalendarGuardian can flag, report, decline, delete, or otherwise act on calendar events when you instruct it to do so or enable a supported automated-protection feature. Detection can produce false positives and false negatives. Platform rules differ, and some providers may require an explicit user action before CalendarGuardian modifies an event.

This End User License Agreement ("Agreement" or "EULA") is between DealDoctor PLLC ("Licensor," "DealDoctor," "we," "us," or "our") and the individual or entity that installs, accesses, purchases, or uses CALENDARguardian™ ("CalendarGuardian" or the "Software") ("you" or "Customer"). By installing, accessing, purchasing, clicking to accept, or using the Software, you agree to this EULA.

1. Definitions

Authorized User means a person permitted to use the Software under your account or subscription. Calendar Provider means Microsoft, Google, Apple, or another third-party calendar or identity provider supported by the Software. Customer Data means information you provide to, connect to, or create through the Software, including calendar data and protection rules. Order means a Marketplace purchase, online subscription, order form, or other transaction that identifies the plan, fees, users, term, or usage limits. Protection Action means an action the Software performs on a calendar event, including flagging, reporting, blocking within CalendarGuardian, declining, deleting, dismissing, quarantining, or recreating available event information.

2. License and subscription

Subject to this EULA, any applicable Order, and payment of applicable fees, DealDoctor grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable right during the applicable term to install, access, and use CalendarGuardian for your internal personal or business purposes. Features, account counts, usage limits, supported Calendar Providers, and automation capabilities may vary by plan, device, and provider.

3. Calendar-provider authorization

You authorize CalendarGuardian to connect to and interact with the Calendar Provider account or device calendar store you select using the permissions you approve. Microsoft connections may use delegated Microsoft Graph permissions that permit CalendarGuardian to read and write calendar information and read basic profile information. Google connections may use Google OAuth/OpenID Connect and Google Calendar API permissions that permit CalendarGuardian to read and edit calendar events and receive authorized calendar-change notifications. Apple-native clients may request full Calendar access through EventKit so the app can read, review, and, when instructed, modify events visible through the Apple device calendar store.

CalendarGuardian does not require your Microsoft, Google, or Apple Account password. Server-side provider connections use OAuth token material where applicable, and Apple EventKit authorization is controlled by the operating system. You represent that you own, control, or are authorized to connect each account, device calendar, and calendar source you use with the Software. You are responsible for ensuring that your use complies with your organization's policies, contractual obligations, professional duties, and applicable law.

4. Detection, reporting, blocking, and automated actions

CalendarGuardian evaluates calendar invitations using rules, content signals, event metadata, links, recurrence, organizer information, user-defined trusted/blocked lists, and other detection methods. Detection is probabilistic and imperfect.

False positives and false negatives can occur. A legitimate event may be flagged or removed, and a malicious or unwanted event may not be detected. You remain responsible for reviewing your calendar and configuring protection settings appropriate for your circumstances.

When you expressly block a sender or domain, CalendarGuardian may automatically act on future matching invitations where the connected provider and applicable platform rules permit that behavior. "Block" means a CalendarGuardian rule unless the Software expressly identifies the action as a provider-level block.

A CalendarGuardian "Report" records your determination that an event is unwanted, junk, phishing, or suspicious. CalendarGuardian will pass a report to the Calendar Provider only when the provider exposes a supported production reporting interface, the required permission has been authorized, and CalendarGuardian expressly identifies that provider-reporting action as enabled. A CalendarGuardian report does not by itself guarantee that Microsoft, Google, Apple, or another provider receives or acts on the report.

5. Removal, decline, notification behavior, and restoration

CalendarGuardian may use Calendar Provider APIs or native frameworks to decline without sending a response, request deletion without attendee updates, delete an event, or perform another supported removal action. Calendar Provider behavior can change and may differ based on account type, client, organizer status, tenant configuration, calendar source, or API semantics. We do not warrant that a removal will be silent to the organizer or other attendees in every circumstance, even when CalendarGuardian requests that provider notifications not be sent.

On Apple platforms, CalendarGuardian's native removal functions are designed to be invoked through an authorized user action consistent with applicable EventKit requirements. Availability of automated background protection may therefore differ from server-connected Microsoft or Google accounts.

If CalendarGuardian offers restoration, it may recreate available event information as a new local calendar event. Restoration may not reconstruct the original organizer-controlled meeting, attendee responses, meeting series relationship, online-meeting link behavior, or other provider state. You should not rely on CalendarGuardian as the sole archive of important meeting information.

6. User controls

You may disable protection, adjust supported thresholds, maintain trusted and blocked rules, review flagged events, revoke provider permissions, and delete CalendarGuardian account data. Certain enterprise plans may allow administrators to apply organization-level settings to Authorized Users. Provider or operating-system settings may impose additional controls.

7. Customer Data and privacy

As between the parties, you retain ownership of Customer Data. You grant DealDoctor a limited right to access, process, transmit, store, and modify Customer Data solely as reasonably necessary to provide, secure, support, and improve CalendarGuardian, comply with law, and enforce this EULA. Our Privacy Policy describes our data practices. Where applicable, the Data Processing Agreement governs processing of Personal Data on behalf of business customers.

8. Acceptable use

You may not use CalendarGuardian to access accounts you are not authorized to access, interfere with another person's calendar, facilitate harassment, evade security controls, distribute malware, violate privacy or communications laws, reverse engineer the Software except where law prohibits this restriction, resell access except under a written reseller agreement, or use the Software to develop or benchmark a competing service in violation of applicable law or contractual restrictions. Additional rules appear in the Acceptable Use Policy.

9. Third-party services

CalendarGuardian depends on Calendar Providers, cloud infrastructure, marketplaces, identity platforms, mobile operating systems, app stores, and other third-party services. Their services are governed by their own terms. We do not control and are not responsible for outages, API changes, permission changes, review requirements, account restrictions, or other acts or omissions of third-party services, although we will use commercially reasonable efforts to adapt CalendarGuardian when practical.

10. Fees, renewals, and billing

Fees, billing interval, renewal terms, trials, cancellation rights, and plan limits are stated in the applicable Order or purchase flow. Marketplace or app-store purchases may also be subject to the applicable marketplace's commerce terms. Except where required by law or stated in an Order, prepaid fees are non-refundable. We may change prices for future renewal periods upon advance notice permitted by the applicable purchase channel.

11. Intellectual property

DealDoctor retains all right, title, and interest in CalendarGuardian, its software, design, detection logic, documentation, branding, and related intellectual property. CALENDARguardian™ and associated CG marks are trademarks of DealDoctor PLLC. DealDoctor® is a registered trademark of DealDoctor PLLC. Feedback you voluntarily provide may be used by DealDoctor without restriction or compensation, provided we do not identify your Confidential Information as feedback.

12. Confidentiality

Each party will use reasonable care to protect the other party's non-public confidential information and will use such information only to perform or exercise rights under this EULA. This obligation does not apply to information that is public through no fault of the receiving party, independently developed, rightfully received without restriction, or required to be disclosed by law.

13. Security

DealDoctor will maintain commercially reasonable administrative and technical safeguards appropriate to the nature of the service. No internet-connected service can be guaranteed completely secure. CalendarGuardian does not represent that it has obtained SOC 2, ISO 27001, or other certification unless we expressly state that such certification has been obtained.

14. Warranties and disclaimers

We warrant that we have authority to license the Software and will use commercially reasonable efforts to provide it substantially in accordance with its documentation during a paid subscription. Your exclusive remedy for a material breach of this limited performance warranty is correction of the nonconformity or, if we cannot reasonably correct it, termination and a refund of prepaid fees for the unused portion of the affected paid term.

EXCEPT FOR THE EXPRESS WARRANTY ABOVE AND TO THE MAXIMUM EXTENT PERMITTED BY LAW, CALENDARGUARDIAN IS PROVIDED "AS IS" AND "AS AVAILABLE." WE DISCLAIM IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT CALENDARGUARDIAN WILL IDENTIFY ALL JUNK, SPAM, PHISHING, OR MALICIOUS INVITATIONS; WILL NEVER FLAG OR REMOVE A LEGITIMATE EVENT; WILL OPERATE WITHOUT INTERRUPTION; OR WILL REMAIN COMPATIBLE WITH EVERY THIRD-PARTY PLATFORM.

15. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, BUSINESS INTERRUPTION, OR LOSS OF DATA, EVEN IF ADVISED OF THE POSSIBILITY. EACH PARTY'S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THIS EULA WILL NOT EXCEED THE AMOUNT YOU PAID TO DEALDOCTOR FOR CALENDARGUARDIAN DURING THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. NOTHING LIMITS LIABILITY THAT CANNOT LAWFULLY BE LIMITED.

16. Indemnification

You will defend and indemnify DealDoctor from third-party claims arising from your unauthorized use of a Calendar Provider account, your unlawful use of the Software, Customer Data you lack the right to process, or your material breach of this EULA. DealDoctor will defend you from a third-party claim that the unmodified Software itself infringes a U.S. patent, copyright, or trademark, subject to customary exclusions for Customer Data, third-party services, modifications, combinations, and misuse. These obligations are subject to the liability limits above to the extent permitted by law.

17. Term and termination

This EULA begins when you first accept, install, access, or use CalendarGuardian and continues until terminated. You may terminate by canceling the applicable subscription, disconnecting accounts, revoking native permissions, and ceasing use. We may suspend or terminate access for material breach, nonpayment, security risk, unlawful conduct, provider requirements, or discontinuation of the service. Upon termination, your license ends. Data deletion and retention are governed by the Privacy Policy and applicable Order.

18. Disputes and governing law

Before initiating a formal dispute, the parties will attempt in good faith for 30 days to resolve it after written notice. Unresolved disputes will be resolved by binding arbitration administered by the American Arbitration Association under its applicable Commercial Arbitration Rules by one arbitrator in New York, New York, except that either party may seek injunctive relief for intellectual-property or confidentiality violations. Claims must be brought individually and not as a class, collective, or representative action to the maximum extent permitted by law. This EULA is governed by New York law without regard to conflict-of-laws rules.

19. Additional terms

You may not use or export the Software in violation of U.S. export-control or sanctions laws. Preview or beta features may be modified or discontinued without service-level commitments. CalendarGuardian will not depend on an unsupported beta provider API for a production-critical function unless that status is expressly disclosed. If an Order conflicts with this EULA regarding commercial terms, the Order controls. If the DPA conflicts regarding Personal Data processing, the DPA controls.

20. Changes and notices

We may update this EULA to reflect product, legal, security, mobile-platform, or Calendar Provider changes. Material changes will be communicated through the service, website, app, or account email where reasonably practicable. Notices to DealDoctor should be sent to legal@dealdoctor.pro.
