Terms of Service

To use Calplanner, you must create an account by providing:

• —A valid email address
• —Your full name
• —A secure password (or use OAuth authentication via Google/Microsoft)

You are responsible for maintaining the accuracy of your account information.

You agree to:

• —Maintain the confidentiality of your login credentials
• —Use a strong, unique password (or enable two-factor authentication if available)
• —Notify us immediately of any unauthorized access or security breach
• —Accept responsibility for all activities that occur under your account

We recommend enabling two-factor authentication when available for enhanced security.

You may not:

• —Share your account credentials with others
• —Create multiple accounts to circumvent service limitations
• —Use another person's account without authorization
• —Register accounts using automated means (bots, scripts)
• —Impersonate another person or entity

When you connect a calendar provider (Google, Microsoft, Zoom), you grant Calplanner limited access to your calendar data via OAuth 2.0 authorization. You may revoke this access at any time through:

• —Your Calplanner account settings
• —The respective provider's account permissions page

Calplanner requests the minimum permissions necessary to provide synchronization services:

• —Google Calendar: calendar.events.owned (read and write to owned calendars)
• —Microsoft Outlook: Read and write calendar events
• —Zoom: Read meeting information

By linking calendars, you authorize Calplanner to:

• —Read events from connected calendars
• —Create synchronized copies (propagated events) on linked calendars
• —Update or delete propagated events when source events change
• —Apply privacy settings (blocked or full visibility) to propagated events

IMPORTANT SYNCHRONIZATION LIMITATIONS:

You acknowledge and agree that:

• —Calendar synchronization is NOT instantaneous and NOT real-time. Synchronization delays can range from seconds to several hours depending on API rate limits, network conditions, provider availability, webhook delivery failures, system load, and other factors beyond our control.
• —Events may fail to synchronize entirely due to API errors, authentication issues, provider outages, data format incompatibilities, or other technical failures.
• —Events may be delayed, duplicated, modified, or deleted during the synchronization process due to conflicts, API limitations, or system errors.
• —Synchronization status displayed in the Service may not accurately reflect the actual state of your calendars on third-party providers.
• —Changes made directly to calendars on third-party providers may not be immediately reflected in Calplanner, and vice versa.
• —If a calendar account requires re-authentication (e.g., expired or revoked refresh token), synchronization for that account will stop until you reconnect it.

YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT:

1. No Substitute for Primary Calendar: Calplanner is a supplementary synchronization tool only and is NOT intended to be your sole or primary calendar system. You must maintain independent access to your original calendar providers and verify all critical events directly with those providers.

2. Verification Obligation: You are solely responsible for independently verifying all calendar events, meeting times, locations, and details directly with your original calendar providers before relying on them. You should never rely solely on Calplanner to display accurate or timely event information.

3. Critical Events: For time-sensitive, mission-critical, or important events (including but not limited to job interviews, medical appointments, legal proceedings, business meetings, travel arrangements, and deadlines), you must verify event details directly with the original calendar provider and set independent reminders outside of Calplanner.

4. Assumption of Risk: You assume all risk associated with using the Service, including but not limited to the risk of:

• —Missing meetings, appointments, or events due to synchronization delays or failures
• —Scheduling conflicts arising from delayed or failed synchronization
• —Events being incorrectly displayed, modified, or deleted
• —Data loss or corruption during synchronization
• —Inaccurate event times, dates, locations, or details
• —Professional, personal, financial, or reputational consequences resulting from any of the above

5. No Reliance: You agree that you will not rely on Calplanner as your sole source of calendar information for any purpose where accuracy and timeliness are important.

You may use Calplanner for lawful purposes to manage and synchronize your personal or business calendars.

You agree not to:

• —Violate any applicable laws, regulations, or third-party rights
• —Use the Service to transmit malware, spam, or harmful content
• —Attempt to gain unauthorized access to our systems or other users' accounts
• —Reverse engineer, decompile, or disassemble any part of the Service
• —Use automated tools (bots, scrapers) to access the Service without permission
• —Interfere with or disrupt the Service's operation or infrastructure
• —Remove, obscure, or alter any proprietary notices (copyright, trademark)
• —Use the Service for competitive analysis or to build a competing product
• —Resell, sublicense, or redistribute the Service without authorization
• —Exceed reasonable API usage limits or abuse synchronization features
• —Use group invite features to spam, harass, or send unsolicited invitations
• —Attempt to brute-force or circumvent group join rate limits

When creating calendar events through Calplanner, you agree not to include:

• —Illegal, defamatory, harassing, or discriminatory content
• —Content that infringes intellectual property rights
• —Sensitive personal information of others without consent
• —Misleading or fraudulent information

Calplanner allows users to create groups for collaborative scheduling. By creating or joining a group, you agree that:

• —Groups have two roles: admin and member. Admins can manage group settings, invite members, remove members, and delete the group. Members can participate, create group events, and leave the group.
• —You are responsible for configuring your own calendar privacy settings within each group (see Section 5A.3).
• —You may leave a group at any time. If you are the only admin, you may need to transfer admin rights or delete the group.

When you participate in a group, the following data is shared with other group members:

• —Your profile information: Name, email address, avatar, role, assigned color, and join date
• —Your calendar events (subject to your privacy settings): Start/end times, timezone, all-day status, and either full event details (title, description, location) or anonymized "Busy" blocks
• —Group metadata: Group name, member count, and creation date
• —Group events: Events created within the group include all members as attendees

You control what calendar data is visible to other group members via per-calendar privacy settings:

• —Full visibility: Other members can see event titles, descriptions, and locations
• —Busy only: Other members see only that you are busy during those times; no event details are shown

You are solely responsible for selecting appropriate privacy settings. Calplanner is not liable for any disclosure of calendar data that results from your privacy settings choices.

Groups can be joined via:

• —Shareable invite links: Generated by admins; anyone with the link may request to join
• —Email invites: Admins may enter an email address to send an invitation. The recipient must have access to that email address to accept the invite

Invite links may expire or be revoked by admins at any time. Rate limits may apply to group join attempts to prevent abuse.

Group events are created on the organizer's connected calendar and include group members as attendees. You acknowledge that:

• —Creating a group event may reveal your availability and event details to members based on your privacy settings
• —You should only join groups with people you trust to see your configured level of calendar information

All content, features, and functionality of the Service, including but not limited to:

• —Software code, algorithms, and architecture
• —User interface designs, graphics, and logos
• —Documentation, tutorials, and help materials
• —Trademarks, service marks, and trade names

are owned by the Calplanner development team and are protected by United States and international copyright, trademark, patent, and other intellectual property laws.

Our collection, use, and disclosure of personal information is governed by our Privacy Policy, which is incorporated into these Terms by reference. Please review our Privacy Policy carefully.

We implement industry-standard security measures to protect your data, including:

• —TLS encryption for data in transit
• —AES-256-GCM encryption for OAuth tokens at rest
• —Access controls and authentication systems
• —Regular security audits and monitoring

However, no internet transmission or electronic storage is 100% secure. You use the Service at your own risk.

While we maintain regular backups, we do not guarantee the ability to recover data in all circumstances. You are responsible for maintaining your own backup copies of important calendar events.

We strive to maintain high service availability but do not guarantee uninterrupted access. The Service may be unavailable due to:

• —Scheduled maintenance (announced in advance when possible)
• —Emergency repairs or updates
• —Third-party calendar provider outages
• —Force majeure events (natural disasters, internet failures, etc.)

We reserve the right to:

• —Modify, suspend, or discontinue any feature of the Service
• —Change synchronization intervals or API rate limits
• —Update system requirements or supported platforms
• —Add, remove, or modify integrations with calendar providers
• —Adjust Free tier limits or Pro features

We will provide reasonable notice of material changes when feasible.

Calplanner integrates with third-party calendar services (Google, Microsoft, Zoom). Your use of these services is governed by their respective terms of service and privacy policies. We are not responsible for:

• —Changes to third-party APIs or service disruptions
• —Data loss or corruption caused by third-party services
• —Privacy practices of third-party providers

Subscription management and payment processing are handled by Polar (and Stripe). Your use of these services is subject to their respective terms:

• —Polar Terms of Service
• —Stripe Services Agreement

Integration with third-party services does not constitute endorsement. We are not liable for the quality, accuracy, or reliability of third-party services.

You may terminate your account at any time. We provide a secure account deletion feature accessible through your account settings that ensures you understand the consequences before proceeding.

#### 11.1.1 Account Deletion Process

When you choose to delete your account, you will be guided through a three-step verification process:

Step 1: Warning and Information

• —You will be shown a comprehensive list of all data that will be permanently deleted, including:
• —All connected calendar accounts and their OAuth access tokens
• —All synced calendar events and event data
• —Your Calplanner account, profile, and preferences
• —All group memberships and associated data
• —You must acknowledge that you understand this action cannot be undone

Step 2: Identity Verification

• —You must verify your identity by entering your account password
• —This prevents unauthorized account deletion by malicious actors or accidental deletion

Step 3: Final Confirmation

• —You must type the confirmation text "DELETE" to confirm your decision
• —The system will display the exact count of calendar accounts and events to be deleted
• —This final step ensures you have made a deliberate, informed decision

Immediate Effects:

• —All OAuth access tokens for connected calendar providers are immediately revoked
• —You will be logged out and redirected to the landing page
• —Your account access is immediately terminated

Data Deletion Timeline:

• —All personal data, calendar connections, and synced events are permanently deleted within 30 days
• —Backup copies in our systems are purged within this period
• —This action is irreversible and cannot be undone

Alternative Method:

• —You may also request account deletion by emailing support@calplanner.com with the subject line "Account Deletion Request"
• —We will verify your identity and process your request within 5 business days

#### 11.1.2 Cleaning Up Propagated Events Before Deletion

Before deleting your account, you may choose to remove propagated (orphaned) events that Calplanner created on your connected calendars. This can be done through the "Clean up" feature in your calendar settings. Note that removing orphaned events does not disconnect your calendars or stop future synchronization — it only deletes existing propagated copies.

We may suspend or terminate your account immediately without notice if you:

• —Violate these Terms or our Acceptable Use Policy
• —Engage in fraudulent or illegal activity
• —Pose a security risk to the Service or other users

We may also terminate inactive accounts (no login for 12+ months) with 30 days' email notice.

Upon termination (whether initiated by you or by us):

Immediate Effects:

• —Your access to the Service is immediately revoked and your session is terminated
• —All OAuth access tokens for connected calendar providers are immediately revoked
• —You will no longer be able to log in or access your account
• —All calendar synchronization stops immediately

Data Deletion:

• —All personal information (name, email, profile data) is permanently deleted within 30 days
• —All calendar connection data and OAuth tokens are permanently deleted within 30 days
• —All synced event data stored in Calplanner's database is permanently deleted within 30 days
• —Billing and subscription data may be retained for a longer period as required for tax, accounting, or legal obligations
• —Backup copies are purged from our systems within 30 days
• —Error logs and diagnostic data containing your information are retained for up to 90 days for troubleshooting, then permanently deleted

Important Notes:

• —Propagated Events: Events that were created on your destination calendars by Calplanner may remain on those calendars after deletion. You are responsible for manually deleting these events from each calendar provider if desired. We recommend using the "Clean up" feature before account deletion
• —Third-Party Data: Data stored directly with third-party calendar providers (Google, Microsoft, Zoom) is not deleted by Calplanner. You must manage that data through each provider's platform
• —No Refunds: No refunds are provided for prepaid subscription fees (except as required by law)
• —Irreversible: Account deletion is permanent and cannot be undone. You will need to create a new account if you wish to use the Service again

This includes job interviews, medical appointments, legal proceedings, business meetings, personal events, travel arrangements, and any other scheduled activities.

• —Scheduling Conflicts: We are NOT responsible for double-bookings, scheduling conflicts, or overlapping events that result from synchronization delays, failures, or inaccuracies.

• —Legal or court scheduling where missed appearances could result in legal consequences
• —Financial trading or time-sensitive business transactions
• —Emergency response or safety-critical applications
• —Any application where synchronization delays or failures could result in significant harm

If you choose to use the Service for such applications, you do so entirely at your own risk.

We are not liable for delays or failures in performance resulting from causes beyond our reasonable control, including:

• —Acts of God (earthquakes, floods, fires)
• —War, terrorism, or civil unrest
• —Internet or telecommunications failures

Before filing any formal claim, please contact us at admin@calplanner.com to attempt to resolve the dispute informally. Include:

• —Your name and contact information
• —A description of the dispute
• —The relief you seek

We will work with you in good faith to resolve the matter.

These Terms are governed by the laws of Sri Lanka, without regard to conflict of law principles.

Note: As we are currently pre-incorporation, the governing law jurisdiction may change once we formally establish our legal entity. We will update these Terms and provide notice if the governing law changes.

For disputes that cannot be resolved informally:

• —Small Claims Court: You may bring claims in small claims court in your jurisdiction if they qualify
• —General Jurisdiction: For other disputes, you consent to the jurisdiction of courts in Sri Lanka
• —No Class Actions: You agree that disputes will be resolved on an individual basis only, not as part of any class action or representative proceeding

This is a simplified dispute resolution process appropriate for our current stage. Upon incorporation and as the service grows, more formal dispute resolution procedures may be implemented.

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Calplanner regarding the Service and supersede all prior agreements and understandings.

We may update these Terms from time to time. Material changes will be communicated by:

• —Posting a notice in the application 14 days before the effective date
• —Sending an email to your registered email address
• —Updating the "Last Updated" date at the top of this document

Continued use of the Service after changes take effect constitutes acceptance. If you do not agree to the updated Terms, you must stop using the Service and may cancel your account.

Our failure to enforce any provision of these Terms does not constitute a waiver of that provision or our right to enforce it in the future.

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions will remain in full force and effect.

You may not assign or transfer these Terms or your account without our written consent. We may assign these Terms to any affiliate or successor entity without restriction.

These Terms do not create any third-party beneficiary rights except as expressly stated.

Nothing in these Terms creates a partnership, joint venture, agency, or employment relationship between you and Calplanner.

Provisions that by their nature should survive termination (including Sections 6, 12, 13, 14, 15, 16) will remain in effect after termination of these Terms.

These Terms are prepared in English. Any translation is provided for convenience only. In the event of a conflict, the English version shall control.
