Kall Privacy Policy

Welcome to Kall, the cross-platform productivity and collaboration service. We treat your personal data privacy as the core foundation of our service operation. This policy applies to all Kall products, websites, mobile applications, browser extensions, and related support services (collectively referred to as the "Services").

By accessing or using our Services, you acknowledge that you have read, understood, and agree to be bound by the terms of this Privacy Policy. We only collect data that is necessary to provide, optimize, and secure our Services, and we never sell your personal data to third parties for commercial purposes.

This policy is designed to comply with applicable privacy regulations in your jurisdiction, and we have implemented global privacy controls that allow you to manage your data preferences regardless of your location.

We use your data exclusively for the following purposes, and we will not use your data for any unrelated purposes without your explicit consent:

• Deliver and maintain the core functionality of the Services, including syncing your content across devices and enabling collaboration features
• Process your transactions, manage your subscription, and send you service-related notifications such as billing alerts and service updates
• Improve product performance, develop new features, and test product updates based on user behavior and feedback
• Detect, prevent, and address security threats, fraudulent activity, and violations of our Terms of Service to protect you and other Kall users
• Provide personalized recommendations and custom experience based on your usage habits, which you can disable in your account settings at any time
• Respond to your support requests and resolve technical issues you encounter while using the Services

We only share your personal data in the following limited circumstances:

• Service providers: We share necessary data with third-party service providers who assist us in operating the Services, such as cloud hosting providers, payment processors, and email delivery services. All our service providers are bound by strict data protection agreements and are prohibited from using your data for any unauthorized purposes.
• Legal requirements: We may disclose your data if required to do so by a valid legal order, or if we believe in good faith that such disclosure is necessary to protect our rights, your safety, or the safety of other users.
• Business transactions: In the event of a merger, acquisition, or sale of all or part of our business, your data may be transferred as part of the transaction, and we will notify you before any transfer takes place and before your data becomes subject to a new privacy policy.
• With your consent: We will share your data with third parties if we have your explicit written or verbal consent to do so.

Note: You can choose to share content with other users via Kall's collaboration features, and such sharing is governed by your own sharing settings.

You have the following rights regarding your personal data, which you can exercise directly in your account settings or by contacting our support team:

• Right to access: You can request a copy of all personal data we hold about you
• Right to correction: You can update or correct inaccurate or incomplete personal data
• Right to deletion: You can request the deletion of your personal data, subject to any legal retention requirements
• Right to data portability: You can export your user-generated content in a machine-readable format for transfer to another service
• Right to withdraw consent: You can withdraw any consent you previously provided for data processing, without affecting the lawfulness of processing based on consent before its withdrawal
• Right to account deletion: You can permanently delete your Kall account at any time, and we will delete all your data within 30 days of account deletion, except for data we are required to retain by law.

We respond to all valid data requests within 30 days, and we do not charge you for reasonable requests unless your request is excessive or repetitive.

We implement industry-standard technical and organizational security measures to protect your data from unauthorized access, use, disclosure, alteration, or destruction:

• All data is encrypted in transit using TLS 1.3 encryption and at rest using AES-256 encryption
• We enforce strict access controls, so only authorized Kall employees can access your data on a need-to-know basis for service purposes
• We conduct regular security audits, vulnerability scans, and employee privacy training to maintain the security of our systems
• We maintain a comprehensive data breach response plan, and we will notify you and relevant authorities of any data breach affecting your personal data as required by applicable regulations

While we take all reasonable measures to protect your data, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee absolute security of your data.

We may update this Privacy Policy from time to time to reflect changes in our practices, product features, or legal requirements. When we make material changes to this policy, we will notify you via email to your registered email address, or via a prominent notice on our website and in-app notification at least 30 days before the changes take effect.

Your continued use of the Services after the effective date of the updated policy constitutes your acceptance of the changes. If you do not agree to the updated policy, you may stop using the Services and delete your account.

If you have any questions, concerns, or requests regarding this Privacy Policy or our data processing practices, you can contact our dedicated data protection team at any time via:
